[00:00:02] <norias> and measure your tooling with it
[00:00:09] <renesis> says cutting tool and consumables management
[00:00:13] <norias> basically, based on how it vibrates
[00:00:18] <norias> as a system
[00:00:27] <norias> they can give you optimal spindle speeds
[00:00:49] <renesis> hmm weird
[00:00:56] <norias> see also stability lobe diagram
[00:01:28] <furrywolf> spotify also requires a binary gender. there's another strike against them.
[00:01:52] <norias> spotify requires a gender?
[00:01:59] <renesis> fuck if i remember
[00:02:20] <norias> is there boys only and girls only music?
[00:02:26] <renesis> maybe
[00:02:44] <furrywolf> apparantly
[00:02:48] <furrywolf> or, more likely, advertising.
[00:02:50] <renesis> furrywolf: hundred days is like 20% the cure and 80% something else i dunno i dont think i like
[00:03:59] <norias> wtf
[00:04:07] <norias> http://www.sciencedirect.com/science/article/pii/S0890695508001296
[00:04:12] <norias> check out that abstract
[00:04:13] <renesis> album title track is totally like late 70s disco sounding the cure tracks
[00:05:34] <furrywolf> sounds like they've automated what a machinist with a practiced ear already does.
[00:05:44] <renesis> norias: so drive tool into spec inclined work, listen for it to scream, make plot?
[00:06:03] <renesis> furrywolf: those guys can cost like $70k/year
[00:06:04] <norias> i think that's what they are saying
[00:06:45] <norias> i think i'm going to pay for this article
[00:07:04] <norias> doing stability lobe diagrams without paying $10k is pretty much my holy grail right now
[00:07:53] <furrywolf> renesis: I'm not sure if I like the hundred days or not... I've only heard a couple of their tracks. hence why I'm looking for an album. lol
[00:08:18] * renesis just gonna listen to the cure f this
[00:08:59] <furrywolf> bah, they only do automatic billing? there's another strike. if money comes out of my account, it's because _I_ initiated it.
[00:11:33] <norias> so, furrywolf
[00:11:45] <norias> the advantage to a stability lobe diagram
[00:11:56] <norias> is usually when you set up a part, and adjust for chatter
[00:12:18] <norias> you are only moving to the closest stable combination of axial depth of cut
[00:12:21] <norias> and spindle speed
[00:12:32] <norias> however, given the mechanics of the system
[00:12:37] <norias> there is an optimal point
[00:12:58] <norias> so, often, the listen and adjust method gets you a suboptimal, but stable, configuration
[00:13:24] <Cromaglious_> hmmm 8" floppy spindle motor to drive a vinyl disc?
[00:13:56] <Cromaglious_> for stero don't you have to move in the z direction too?
[00:14:19] <Cromaglious_> s/stero/stereo/
[00:14:21] <furrywolf> Cromaglious_: the secret to driving vinyl is a big hunk of steel. doesn't matter much what you turn it with. :)
[00:14:47] <Cromaglious_> true... or a hunk of marble
[00:15:21] <furrywolf> I was working on a direct-drive turntable once, and with the big heavy weight removed, it'd snap 1/3rd of a rotation at a time.
[00:15:43] <furrywolf> i.e. rotate 120 degrees. stop. rotate 120 degrees. stop. etc.
[00:16:14] <furrywolf> it was entirely dependent on a big weight to make that into smooth movement
[00:16:19] <Cromaglious_> I had a BSR turntable with a marble platter with a rubber mat
[00:17:24] <Cromaglious_> neon light to adjust the speed with a pot to control the speed of the 6v dc motor
[00:18:27] <furrywolf> yep, I've worked on those. several rows of black/chrome around the platter if it's multi-speed too.
[00:18:50] <furrywolf> hrmm, sourceforge seems to be returning 503s today.
[00:19:04] <Cromaglious_> yep, 33 1/3,45,78
[00:19:17] <Cromaglious_> man those 78's ate needles
[00:19:54] <Cromaglious_> I'd almost want to make a laser reader to play 78's
[00:20:58] <furrywolf> from what I know, non-contact players never really worked well.
[00:22:10] <Cromaglious_> they didn't have the sensors they have today
[00:24:33] <furrywolf> I wonder if you could adopt one of those capactive video disc heads to read audio vinyl...
[00:27:22] <Cromaglious_> IRENE at the library of congress takes pictures of the grooves and then constructs a model of the record
[00:27:42] <Cromaglious_> only does monophonic records which is OK for 78's
[00:28:59] <Cromaglious_> micro 3d scanner would work for the grooves for stereo and quadraphonic records. Just have to have a high speed blast of clean air to clean the dust out of the groves
[00:29:31] <furrywolf> the capacitive heads were cool... they worked like CD heads with tracking coils to center the stylus...
[00:32:19] <Cromaglious_> I'm thinking 2 tracking lasers reflecting into ccd's for tracking and another laser with beam splitter to read the sides at 3 places on each side, and depth
[00:33:17] <furrywolf> if you think you can get an accurate reflection, have fun...
[00:33:45] <Cromaglious_> build a 3d model of the groove, post process for dust and scratches.
[00:34:31] <Cromaglious_> a scratch would have an angle different than the original press.
[00:35:05] <Cromaglious_> maybe use those usb microscopes
[00:35:30] <Cromaglious_> and structured light
[00:50:22] <norias> structured light!
[00:50:27] <norias> yippee!
[00:57:05] <furrywolf> bbl, wolfy bedtime
[00:58:52] <t12> interferometric turntable
[00:59:40] <furrywolf> by the time you get into spending that much money, you'll want to be digging masters out of old warehouses, not using consumer pressings...
[01:51:15] <Cromaglious_> money? $20 usb microscope and a slide projector converted to LED?
[01:55:56] <renesis> that prob wont work well
[01:56:12] <renesis> those $20 usb microscopes are total shit, nowhere near what you need
[01:56:20] <renesis> can barely use them for PCBA inspection
[01:56:55] <renesis> 3 bosses have thrown me that shit for documentation, everytime ive ended up using the real microscope and my smartass phone cam
[02:13:00] <Deejay> moin
[02:33:07] <Cromaglious_> Hmm there's an idea... get a decent webcam and stick a magnafying macro lens on it
[03:07:47] <Jymmm> archivist: Do you know by chance if electro-etching can be used to (essencially) "polish" brushed SS ?
[03:09:38] <Jymmm> archivist: I want to basically remove some laser engraving
[03:11:51] <archivist> I would use wet and dry paper to match the brushing
[03:12:59] <Jymmm> archivist: Good idea, thank you =)
[03:14:46] <Jymmm> I'm trying my hand at vaping, and want to customized it some =)
[03:16:17] <Tecan> Vapor deposition ?
[03:16:39] <Jymmm> Tecan: As a way to reduce/quit smoking
[03:17:50] <Tecan> http://netpipe.ca/netpipe/?page_id=286
[03:18:44] <Jymmm> Tecan: tl;dr
[03:19:57] <Jymmm> Tecan: is that yours?
[03:20:12] <Tecan> ya
[03:20:37] <Jymmm> Reading...
[03:20:48] <Tecan> i almost died because i put moonshine in my vape mix lol
[03:22:37] <Jymmm> vpaping is far older than 4 years, almost 9 years that I'm aware of.
[03:23:01] <Jymmm> I just threw out 5yo juice =)
[03:24:16] <Jymmm> I just can't do nic at all it seems (ironic I know)
[03:24:31] <Jymmm> at least not without coughing up a lung or three
[03:24:39] <Tecan> nic is just to turn off the smoke craving response
[03:24:50] <Tecan> vg on its own is way more powerful
[03:24:56] <Jymmm> I can't vape nicotine at all
[03:25:46] <Jymmm> I'd avoid SOY just due to the GMO personally
[03:25:59] <Tecan> without nic vg still changes my vision gives an energy boost and feels like a smoke
[03:26:40] <Jymmm> MY VG is non-gmo, kosher, and palm or vegetable based
[03:26:42] <Tecan> i quit for 3 months and started back up on cigars as a victory smoke lol
[03:26:45] <Tecan> ideot
[03:26:51] <Jymmm> lol
[03:27:18] <Tecan> those prime time rum and wine cigars are tasty
[03:27:23] <Jymmm> You can use a drop of water to thin VG btw
[03:27:53] <Tecan> the water was making my spleen hurt
[03:28:02] <Tecan> it was sticking to my tissue more
[03:28:25] <Jymmm> a DROP of water?
[03:28:30] <Tecan> more vg being absorbed into my body
[03:28:39] <Jymmm> ah
[03:28:41] <Tecan> you have to keep the smoke really cool for those big clouds
[03:29:05] <Jymmm> Maybe you have a reaction to PG and/or VG in general, many do.
[03:29:32] <Jymmm> I'm not a cloud chaser, I prefer flavor
[03:31:22] <Jymmm> But I got VERY lucky and this build it hitting great
[04:17:00] <Swapper> i have a basic question, when i load gcode in to linuxcnc i always have to "rotate" the layout to get the x-y orient to make sens visualy, no problem milling it its only the gui thats rotating it wrong.
[04:17:18] <Swapper> can i be that i have +- orientation wrong or somting ?
[04:44:17] <SpeedEvil> Simply rotate your screen 90 degrees.
[04:44:22] <SpeedEvil> (sorry - no sensible answer)
[04:44:26] <Swapper> hehe
[04:44:53] <Swapper> i have to rotate the cooridnate in the gui every time to get the orient to match the jog directions
[04:45:12] <Swapper> its a silly thing but...
[05:00:59] <SpeedEvil> Annoying enough.
[08:21:52] <Swapper> omg i hate welding stainless
[08:21:55] <Swapper> its hopless
[08:23:31] <archivist> use the right welder :)
[08:33:38] <_methods> wow most people love welding it
[08:34:03] <_methods> welders at my shop will fight for a stainless job
[08:35:00] <archivist> cast iron is hard work to do properly
[09:17:43] * jthornton tries to figure out how to make a symbolic link to the 2TB drive on sdb1
[09:18:20] <furrywolf> ln -s /whatever /wherever
[09:18:44] <jthornton> what is where ever on a different drive?
[09:19:14] <furrywolf> doesn't matter.
[09:19:29] <furrywolf> symbolic links can point to anything you want, even things that don't exist....
[09:19:48] <jthornton> so how to you point to another drive?
[09:20:39] <furrywolf> ... /whereevertheotherdriveismounted/somewhere/...
[09:20:39] <furrywolf> all things on *nix are mounted into a single tree
[09:21:33] <archivist> one often just mounts on some directory in fstab like usb drives appear on /media
[09:21:58] <jthornton> http://pastebin.com/tDKbdNfX
[09:22:00] <archivist> as usual more than one way to skin this cat
[09:22:29] <Tom_itx> yeah i did that once but forgot how, it linked the whold drive as a directory
[09:22:31] <jthornton> lol I can't even create a directory on the drive... I guess I don't "own" it
[09:22:45] <furrywolf> looks like your automount is mounting it as /media/6821c43c-d4b9-486a-a36c-9645cb1c4edd. so ln -s /media/6821c43c-d4b9-486a-a36c-9645cb1c4edd/furryporn /home/jt/
[09:22:49] <_methods> yeah much better to fstab
[09:25:17] <Tom_itx> https://help.ubuntu.com/community/Fstab
[09:25:23] <archivist> automount is the new fangled method for usb devices, silly thing has remembered a cf card on this box!
[09:29:14] <furrywolf> it rained a bit yesterday, so I wasn't planning on yard sales today... but it looks like today might clear up nicely. hrmm.
[09:30:19] <jthornton> looks like the type is wrong for sdb1 http://pastebin.com/02XVYGM8
[09:30:39] <jthornton> from what I've read it needs to be ext4 for backuppc
[09:30:49] <jthornton> out to the shop for a bit
[09:31:02] <archivist> define wrong
[09:31:18] <furrywolf> ext4 and ext3 are very compatible
[09:31:24] <jthornton> it's ext2 and I think it needs to be 4
[09:31:34] <jthornton> see the pastebin
[09:31:47] <archivist> I think linux can mount almost any type
[09:32:08] <archivist> if it is ext2 then mount as same
[09:32:09] <furrywolf> ext2 is very old. how old is this drive? lol
[09:32:17] <jthornton> not linux issue but backuppc needs ext4
[09:32:24] <jthornton> 1 day old
[09:32:31] <jthornton> lol
[09:32:48] <jthornton> I think I need to format it
[09:32:48] <furrywolf> how the hell did you even manage to format it as ext2?
[09:32:52] <archivist> then format it properly next time :0
[09:33:05] <jthornton> I didn't format it I just created a partition
[09:33:10] * furrywolf wasn't aware any modern system even included utilities to do that
[09:33:14] <jthornton> with gpart
[09:35:10] <furrywolf> completely random question: is there any reason speaker cones have to be conical? what about a paraboloid?
[09:38:08] <furrywolf> hrmm. I'd need to work out the minimum diameter for acceptable frequency response...
[09:40:55] <archivist> I bet it has been tried
[09:43:23] <Tom_itx> just don't ask an audiophool
[09:43:59] <archivist> I should go look in some text books http://www.collection.archivist.info/searchv13.php?searchstr=sound+bk
[09:45:01] <archivist> warfedale will have measured /me wanders off upstairs
[09:51:28] <furrywolf> looks like I wouldn't have enough available space. oh well.
[09:53:57] <archivist> no mention of cone shape on a skim read, lots of graphs of response measurements with different cabinets and crossovers etc
[09:54:21] <zeeshan|2> archivist: that book by ab wood
[09:54:22] <zeeshan|2> is pretty decent
[09:54:31] <zeeshan|2> i referred to it in my acoustics course
[09:54:45] <furrywolf> Rayleigh says my plan wouldn't work, so even if the speaker would work, the overall idea is a bust.
[09:54:52] <archivist> was about to go back upstairs to drag it out :)
[09:55:47] <zeeshan|2> two other books i used a lot was
[09:55:55] <archivist> I have a load od audio stuph not catalogued yet as some I regarded as audiophool grade
[09:56:39] <zeeshan|2> "industrial noise control and acoustics" by randall baron and "fundamentals of acoustics" by lawrence kinsler
[09:56:47] <furrywolf> I thought of an application where you could combine a loudspeaker and parabolic microphone, but it'd take an annoyingly large loudspeaker... so whether the cone shape would be acceptable is irrelevant. heh.
[10:01:19] <archivist> furrywolf, the UK made some parabolic reflectors during the war for long distance listening and may have had drivers too
[10:02:39] <archivist> ah ww1 http://en.wikipedia.org/wiki/Acoustic_mirror
[10:03:30] <Tom_L> lrad doesn't use a cone
[10:08:11] <zeeshan|2> man how do you make a chamfer mill
[10:08:13] <zeeshan|2> take a helical path!!
[10:09:16] <furrywolf> ?
[10:09:26] <furrywolf> same way you make any other mill?
[10:09:28] <zeeshan|2> mastercam being a slut
[10:09:35] <Tom_itx> why would you want to?
[10:09:43] <Tom_itx> wtf are you making?
[10:09:43] <zeeshan|2> cause im making a deep chamfer
[10:09:51] <archivist> use human cam
[10:09:51] <zeeshan|2> and doing it on the mill
[10:10:34] <zeeshan|2> http://i.imgur.com/XZc0MJ0.png
[10:10:37] <zeeshan|2> basically that tool path
[10:10:39] <furrywolf> " Since the mounting depth in my car is so shallow, the installer had to remove the factory terminal lugs from the speaker. Then he sodered the speaker wire directly to the tinsel leads." ... the things you find googling for info on repairing broken tinsels. lol.
[10:10:40] <zeeshan|2> that doesnt take 10 hours
[10:10:51] <zeeshan|2> i wanna step the big chamfer with a 3/8 end mill
[10:10:55] <zeeshan|2> .050 scallops
[10:11:03] <zeeshan|2> and then come clean it up with a chamfer mill
[10:11:39] <Tom_itx> how big a chamfer?
[10:12:07] * Tom_itx looks at zeeshan|2's show n tell
[10:12:21] <zeeshan|2> .30" x 45
[10:12:23] <zeeshan|2> deg
[10:12:42] <zeeshan|2> ive done this on straight parts with chamfer
[10:12:42] <Tom_itx> ball nose it
[10:12:45] <zeeshan|2> but those techniques dont work
[10:12:46] <zeeshan|2> no
[10:12:50] <zeeshan|2> i wanan do it quick
[10:12:59] <furrywolf> just put it on your 5-axis mill and rotate it at a 45 degree angle about the axis of your hole.
[10:13:03] <Tom_itx> cram the cutter in there then
[10:13:18] <zeeshan|2> i wanna remove the bulk with the regular flat bottom end mill
[10:13:20] <_methods> HHAHAHHAHAHHAHAH
[10:13:44] <Tom_itx> do it on a 5 axis and tilt the part
[10:14:02] <zeeshan|2> yes, let me setup a 5 axis
[10:14:03] <zeeshan|2> just for this
[10:14:04] <zeeshan|2> :-)
[10:14:10] <_methods> plz do
[10:14:20] <zeeshan|2> i can throw this on the lathe and get it done
[10:14:24] <zeeshan|2> but id like to do it in one setup
[10:14:28] <Tom_itx> there's your best bet
[10:14:28] <zeeshan|2> i wish someone used mast4ercam in here
[10:14:40] <zeeshan|2> ive seen it done before, but i dont know which path it was
[10:14:52] <Tom_itx> ?
[10:15:05] <Tom_itx> do it the same way you spiral down the center
[10:15:07] <furrywolf> masturcam... when you only use it by yourself.
[10:16:21] <Tom_itx> if you use a ball nose to 'step' down you will remove more material than a flatbottom em
[10:16:24] <Cromaglious_> woo 7.9 earthquake in Nepal
[10:16:32] <Tom_itx> just saw pics of that
[10:17:05] <Tom_itx> at least 700 dead
[10:17:53] <Cromaglious_> not the most earthquake safe construction standards
[10:18:20] <Tom_itx> zeeshan|2 ^^
[10:18:54] <Cromaglious_> up to 906 now
[10:19:42] <Cromaglious_> 876 in Nepal, 20 in India, 6 in Tibet and 2 in Bangladesh
[10:21:27] <jthornton> hmm sdb1 is owner is root :(
[10:22:27] <_methods> i am groot
[10:23:26] <zeeshan|2> http://i.imgur.com/WqgQxvN.png
[10:23:30] <zeeshan|2> thats what it looks like right now
[10:23:33] <furrywolf> to yard sale or not to yard sale, that is the question. Whether 'tis nobler in the mind to suffer, to sit at home and ponder what deals might have been, or to take action against these doubts, and drive around in poor weather?
[10:23:40] <zeeshan|2> what is the tool path called for chamfer milling!
[10:24:00] <Tom_itx> zeeshan|2, if you use a ball nose you will remove mor material than a flatbottom mill
[10:24:09] <_methods> ahhh comeon i liked the other one better
[10:24:14] <zeeshan|2> Tom_itx: i dont wanna change tools
[10:24:19] <Tom_itx> pfft
[10:24:21] <_methods> just make sure you video it for me when you run it
[10:24:26] <_methods> like your clamping video
[10:24:26] <Tom_itx> lazy
[10:24:31] <zeeshan|2> _methods fuck off
[10:24:36] <_methods> hahahhaha
[10:24:40] <Tom_itx> heh
[10:25:01] <Tom_itx> that _was_ awesome!
[10:25:02] <zeeshan|2> i share it for a laugh
[10:25:16] <zeeshan|2> not for your continuous trolling
[10:25:19] <_methods> and i think you
[10:25:20] <zeeshan|2> and acting like you know what you're doing
[10:25:21] <zeeshan|2> :-)
[10:25:27] <_methods> lol
[10:25:33] <Tom_itx> when it's out there... it's out there.
[10:25:45] <zeeshan|2> it's out there for a reason, cause its interesting
[10:25:48] <zeeshan|2> most machining is boring
[10:26:00] <zeeshan|2> ive made 20 other parts in that time period that are typical
[10:26:12] <Tom_itx> boring is but one part of machining :D
[10:26:31] <zeeshan|2> if you expect it to do something silly, you video it
[10:26:33] <zeeshan|2> :-)
[10:27:02] <zeeshan|2> _methods i'm an engineer
[10:27:03] <Tom_itx> just don't let the EM gouge the surface you want smooth
[10:27:04] <zeeshan|2> i know all
[10:27:09] <zeeshan|2> except how to do this tool path!
[10:27:10] <Tom_itx> i'm still suggesting a ballnose
[10:27:22] <zeeshan|2> Tom_itx: im leaving .050 from the surface of interest
[10:27:28] <zeeshan|2> im using it to remove the majority of the material
[10:27:36] <furrywolf> "Hold my beer and watch this!" is generally a good cue to get the camera rolling.
[10:27:41] <zeeshan|2> so the chamfer mill doesnt have to do as much work
[10:27:48] <furrywolf> Tom_itx: I told him to use a ballnose yesterday. he didn't listen then either.
[10:28:05] <zeeshan|2> i didnt ask for suggestions on how to do it furry
[10:28:11] <Tom_itx> it's still a lathe job...
[10:28:12] <zeeshan|2> i was asking on how to generate the tool path specifically to what i want
[10:28:28] <Tom_itx> join ###mastercam
[10:28:30] <zeeshan|2> Tom_itx: i don't wanna risk it losing concentricity
[10:28:48] <Tom_itx> i know how to do it in smartcam
[10:28:48] <zeeshan|2> its easier to do it in one setup
[10:28:56] <furrywolf> you need that cnc boring head someone here pasted yesterday
[10:28:57] <zeeshan|2> well maybe its similar in master?
[10:29:01] <Tom_itx> i doubt it
[10:29:25] <Tom_itx> i would group the surface and do a helix with an offset
[10:29:42] <Tom_itx> or spiral
[10:30:14] <Tom_itx> the problem with using a spiral or helix is by the end of the first pass you're too deep
[10:30:56] <Tom_itx> i fear chatter on your chamfer cut
[10:32:08] <zeeshan|2> its a proper chamfer mill
[10:32:32] <zeeshan|2> http://blog.supertoolinc.com/wp-content/uploads/2013/05/chamfer-cutter.jpg
[10:32:33] <zeeshan|2> like that
[10:34:15] <zeeshan|2> figured it out
[10:34:20] <zeeshan|2> it was just circular milling tool path
[10:34:28] <zeeshan|2> but the start angle had to be the same as my chamfer angle
[10:35:37] <zeeshan|2> 8 min to run entire program
[10:35:39] <zeeshan|2> more like it!
[10:38:02] <jthornton> I finally got it... create a ext4 partition that shows up in /media/partitionname and chown to me!
[10:38:14] <jthornton> now for some honey dews
[10:38:24] <_methods> hehe
[10:40:54] <zeeshan|2> furrywolf:
[10:40:55] <zeeshan|2> http://www.kijiji.ca/v-tool-other/hamilton/vise/1065921850?enableSearchNavigationFlag=true
[10:41:02] <zeeshan|2> lol
[10:49:18] <JT-Shop> when you don't know jack shit about what you need to do it is very hard to figure out what to do... as always when you know how it is easy
[10:51:15] <_methods> < zeeshan|2> i know all
[10:51:45] <zeeshan|2> man these starrett tap handles have sky rocketed in prices after all the machinist youtubers have been talking about them
[10:52:33] <zeeshan|2> _methods don't you love it when i troll back? :]
[10:53:45] <Tom_itx> single edge chamfer will give you less chatter
[10:54:18] <zeeshan|2> cat40 ftw!
[10:54:25] <Tom_itx> 50
[10:54:51] <zeeshan|2> its okay if i get chatter on that surface
[10:54:56] <Tom_itx> rulz
[10:54:57] <zeeshan|2> its just a viewing surface for the 3d cameras
[10:55:14] <zeeshan|2> i mean it allows viewing
[10:55:45] <zeeshan|2> http://i.imgur.com/zJRzJ8I.jpg
[10:55:46] <zeeshan|2> if i dont chamfer
[10:55:53] <zeeshan|2> then you see that small shadow
[10:56:32] <Tom_itx> then just use the step mill and call it good
[10:56:40] <zeeshan|2> haha
[10:58:16] <zeeshan|2> http://i.imgur.com/3bEuowG.jpg
[10:58:20] <zeeshan|2> you get that nonsense on the corners
[10:59:20] <Tom_itx> use a ballnose on a single pass and disregard the chamfer cut
[10:59:35] <Tom_itx> it would be smooth enough
[11:01:12] <zeeshan|2> i just realize, the botom part of the die
[11:01:16] <zeeshan|2> ill prolly have to put on the lathe anyway
[11:01:18] <zeeshan|2> :/
[11:01:24] <Tom_itx> hehe
[11:01:27] <zeeshan|2> fak
[11:01:37] <_methods> i love it when you troll back
[11:01:37] <Tom_itx> why? for the seal ring?
[11:01:47] <_methods> on yourself lol
[11:01:50] <zeeshan|2> air pressure distribution chamfer
[11:01:54] <zeeshan|2> chamber thing
[11:02:03] <zeeshan|2> _methods: COOL STORY
[11:02:39] <Tom_itx> i thought you already made one of these
[11:02:43] <zeeshan|2> i did
[11:02:49] <zeeshan|2> now im making another set
[11:02:55] <zeeshan|2> with larger diameters
[11:02:58] <Tom_itx> so what did you do the first time?
[11:03:05] <zeeshan|2> oh i didnt chamfer it
[11:03:08] <zeeshan|2> it was a flat bottom
[11:06:59] <zeeshan|2> http://i.imgur.com/VOG0oOr.png
[11:07:01] <zeeshan|2> there tom
[11:07:04] <zeeshan|2> see the steep angle
[11:07:08] <zeeshan|2> i think lathe is needed =/
[11:07:23] <Tom_itx> been saying that a while now
[11:07:31] <Tom_itx> or 5 axis
[11:07:42] <zeeshan|2> i don thave a 5 axis!
[11:07:42] <jthornton> hmm after booting up media/backup requires a password to gain access to it
[11:08:00] <Tom_itx> password: cannonshot
[11:08:31] <Tom_itx> no way to disable that?
[11:11:30] <Tom_itx> you need an air deflector on the inside so it doesn't blast that tiny hole straight ahead to the test specimen
[11:11:53] <zeeshan|2> its incremented in small amounts
[11:11:56] <zeeshan|2> .5psi
[11:12:16] <zeeshan|2> but i didnt have enough chamber voume
[11:12:23] <zeeshan|2> *volume
[11:12:30] <zeeshan|2> so that means that i can't use the assumption of uniform pressure
[11:13:04] <Tom_itx> make it a sphere
[11:13:18] <zeeshan|2> Tom_itx: this chamfer is standard design
[11:13:30] <zeeshan|2> thats why im using it
[11:13:31] <Tom_itx> i'm just overengineering it for you
[11:13:34] <zeeshan|2> haha
[11:14:13] <Tom_itx> you didn't listen about the lathe so i figured you would ignore me now too
[11:15:20] <Tom_itx> the time you've spent on cad you could have had the part by now :)
[11:15:56] <Tom_itx> now i'm just messin with ya...
[11:15:58] <zeeshan|2> =D
[11:16:30] <zeeshan|2> i don't mind getting trolled by someone who knows what they are talking about :-)
[11:17:21] <Tom_itx> i sure got you fooled :D
[11:17:28] <zeeshan|2> haha
[11:19:41] <zeeshan|2> http://tetech.com/products/tc-36-25-rs232/
[11:19:44] <zeeshan|2> i was so ready to buy thsi thing
[11:19:55] <zeeshan|2> but damn it it uses thermistors
[11:20:12] <zeeshan|2> they have crap stability and linearity
[11:24:09] <pcw_home> Platinum RTDs FTW
[11:25:35] <zeeshan|2> man maybe its better to juse circular liquid nitrogen through this
[11:25:43] <zeeshan|2> and have a heating coil and use a regular temperature controller
[11:25:59] <zeeshan|2> circulate
[11:26:05] <pcw_home> At one time HP had a thermometer that used a Quartz crystal oscillator cut so it had a large tempco
[11:26:25] <zeeshan|2> tempco?
[11:26:30] <zeeshan|2> coefficient?
[11:26:45] <pcw_home> temperature coefficient
[11:28:00] <zeeshan|2> peltier vs liquid n2+heating element
[11:28:03] <zeeshan|2> what to do!!
[11:28:11] <archivist> that is way back 1960's :)
[11:29:55] <pcw_home> I probably read about it in a HP journal in the 60s...
[11:30:19] <archivist> I have catalogues going way back, where I read it :)
[11:31:24] <zeeshan|2> my instincts tell me the liquid n2 and heating element would have better cooling rates
[11:31:26] <zeeshan|2> vs a peltier
[11:31:29] <zeeshan|2> cooling/heating
[11:31:56] <archivist> peltier can be poor
[11:32:14] <archivist> dissipates too much internal heat
[11:33:58] <pcw_home> getting linear control of the ln2 cooling rate may be entertaining
[11:34:12] <archivist> pcw_home, I also have an app note from 1983 Practical temperature measurements application note 290
[11:34:14] <zeeshan|2> pcw_home: we already have an instron chamber
[11:34:21] <zeeshan|2> that is supposed to
[11:34:45] <zeeshan|2> i was thinking of ripping its controller and solenoids
[11:34:53] <zeeshan|2> and using it for my application
[11:35:42] <zeeshan|2> theres a fan, it blows a mist of liquid n2
[11:35:51] <zeeshan|2> to cool
[11:36:02] <zeeshan|2> (doesn't circulate it)
[11:36:48] <zeeshan|2> think that would give a linear cooling rate?
[11:43:22] <zeeshan|2> http://myhoneysplace.com/wp-content/uploads/2013/02/oh-no-13.jpeg
[11:43:24] <zeeshan|2> nice
[11:43:58] <Tom_itx> tank leak test
[11:44:05] <Tom_itx> they pass
[11:44:09] <zeeshan|2> haha
[11:46:21] <zeeshan|2> man i gotta start working on this throttle body for a customer today
[11:46:43] <zeeshan|2> http://i73.photobucket.com/albums/i225/nvmyre/throttlebody/16072008026.jpg
[11:46:44] <zeeshan|2> go from that
[11:46:45] <zeeshan|2> to:
[11:46:49] <zeeshan|2> http://i73.photobucket.com/albums/i225/nvmyre/throttlebody/16072008025.jpg
[11:47:14] <zeeshan|2> im thinking of keeping it simple and just dialing in each bore, then using the boring head to make them larger
[11:47:30] <zeeshan|2> and then machining out the brass plates
[11:56:02] <furrywolf> why would you use three small butterflies instead of one big one?
[11:56:17] <zeeshan|2> ??
[11:56:22] <zeeshan|2> oh
[11:56:27] <zeeshan|2> its a 2 stage tb
[11:57:23] <furrywolf> yes, that's what it is... that doesn't answer WHY.
[11:57:43] <zeeshan|2> you asked why three butterflies
[11:57:45] <zeeshan|2> vs one big one
[11:57:49] <zeeshan|2> i was pointing out its a 2 stage tb
[11:57:53] <furrywolf> unless that's for some weird carb I've never seen, not efi.
[11:57:56] <zeeshan|2> the top butterflies open together and bottom opens diff
[11:58:02] <zeeshan|2> it is for efi
[11:58:06] <zeeshan|2> its for a rotary engine
[11:58:13] <zeeshan|2> you want a progressive opening
[11:58:22] <zeeshan|2> otherwise you get huge tip in fuel tuning issues
[11:59:21] <furrywolf> that seems like something that should be addressed with software and/or sensor improvements, not an overly complicated throttle body. heh.
[11:59:35] <furrywolf> my car has one, about 3" around. nice, simple. a tps on one side, a cable on the other. lol
[11:59:43] <zeeshan|2> every rotary engine has a tb like this
[11:59:45] <zeeshan|2> there is a reason for it
[12:00:01] <zeeshan|2> cause you cant controll the transient velocity through software fast enough
[12:00:13] <zeeshan|2> control the transient fueling fast enough
[12:00:27] <zeeshan|2> i dont know. i didnt design the engine :p
[12:00:50] <furrywolf> lol
[12:01:43] <Tom_itx> rotaries are a fail
[12:01:49] <zeeshan|2> ^ totally agree
[12:01:55] <zeeshan|2> but it doesnt stop me from making money from them! :D
[12:02:36] <zeeshan|2> ill never run one again
[12:02:42] <zeeshan|2> unless its a water pump or something
[12:02:42] <zeeshan|2> :)
[12:02:59] <zeeshan|2> (removing the compression phase)
[12:03:00] <Tom_itx> years ago a friend raced one. he was always blowing seals out
[12:03:06] <Tom_itx> even with the comp seals
[12:03:26] <zeeshan|2> tom if you take one apart
[12:03:27] <zeeshan|2> you can see why
[12:03:33] <Tom_itx> i know why
[12:03:44] <Tom_itx> rotaries are a fail
[12:03:56] <zeeshan|2> http://www.ridelust.com/wp-content/uploads/wankel-inside-kart-engine.jpg
[12:04:02] <zeeshan|2> see the wave springs?
[12:04:14] <zeeshan|2> carbon gets in them and they stop being springy and bam sealing fail
[12:04:15] <Tom_itx> i know
[12:04:30] <zeeshan|2> 3 moving parts my ass
[12:04:30] <zeeshan|2> :)
[12:04:47] <zeeshan|2> http://www.carthrottle.com/wp-content/uploads/2013/08/2531-communism-engine-rotary-theory-655x524.jpg
[12:04:48] <zeeshan|2> rofl
[12:05:13] <furrywolf> googling suggests the stupid throttle body goes with stupid injectors, and a modern system wouldn't need it.
[12:05:38] <zeeshan|2> the injectors are way further up
[12:05:49] <Tom_itx> bbl
[12:09:07] <archivist> pcw_home, quartz thermometer still in the catalogue in 1991
[12:09:40] <furrywolf> the new engines only have a single butterfly. :)
[12:10:26] <zeeshan|2> they do
[12:10:29] <zeeshan|2> but they're also electronic
[12:10:44] <zeeshan|2> so they control the tip in accel control
[12:10:58] <furrywolf> apparantly has to do with velocity through the intake ports... I guess the stupid combustion chamber shape needs high velocity air for scavanging purposes or such.
[12:11:25] <archivist> mixing too
[12:11:27] <furrywolf> the old design used a separate butterfly to only let air though a small port to keep the velocity high
[12:12:39] <furrywolf> I toyed with designing a vane pump engine a while ago... should build one one of these days.
[12:13:11] <archivist> that will last a few seconds
[12:13:35] <furrywolf> no, I got the relative velocity of all the seals down nice and low, much better than a wankel...
[12:14:02] <archivist> shite still gets where you dont want it
[12:14:14] <zeeshan|2> lol
[12:14:38] <furrywolf> I couldn't identify any part of the design that would work worse than a wankel. :P
[12:14:42] <furrywolf> now, that's not much of an endorsement, of course...
[12:14:44] <zeeshan|2> furrywolf: you destroyed 100 mazda engineers w/ one design
[12:14:48] <zeeshan|2> you should go school them
[12:14:59] <zeeshan|2> show em how it's done
[12:15:22] <zeeshan|2> maybe melt all the rotary engines and cast them into something more useful
[12:15:23] <zeeshan|2> :-)
[12:15:36] <furrywolf> lol
[12:15:38] <archivist> sculptures ?
[12:15:42] <zeeshan|2> that'd work
[12:15:43] <zeeshan|2> :D
[12:16:28] <furrywolf> my design has a whole lot more moving pieces. even if it works, it's probably not economical. but it'd still be interesting to try building one.
[12:16:51] <furrywolf> it even had variable cutoff between the compressor and "turbine" parts. :)
[12:17:15] <furrywolf> it works (assuming it does) more like a jet engine than a otto engine.
[12:17:19] <furrywolf> brayton
[12:17:42] <pcw_home> roots engine
[12:18:06] <pcw_home> no seals! (or walruses)
[12:18:16] <furrywolf> also no expansive use of pressure
[12:18:19] <furrywolf> = crap efficiency
[12:18:36] <archivist> lolrus engine
[12:18:52] <zeeshan|2> v8
[12:19:15] <furrywolf> roots steam engines were built for specialized purposes... the efficiency was too crap for general use.
[12:19:17] <pcw_home> sure it does, its just s high pressure turbojet
[12:23:06] <furrywolf> it's continuous combustion, and a lot more like a jet (brayton cycle) engine than a spark ignition otto engine... just built with vane pumps instead of turbines. tried designing an engine that'd have some of the benefits of turbines, but over a wide rpm range, as it was positive displacement instead of depending on aerodynamics...
[12:23:45] <furrywolf> the hard part is making a vane pump that can expand combustion temperature gasses without promptly failing... or needing new apex seals weekly, like a rotary. :)
[12:25:52] <furrywolf> bbl, going to try yard sales
[12:26:11] <SpeedEvil> Good luck finding exotic superalloys there.
[12:26:46] <SpeedEvil> There is interesting work done on full sized aeroplane turbines
[12:27:04] <SpeedEvil> Actively modulating the gap between the case and the turbine blades.
[12:27:12] <furrywolf> turbines are inherently limited to a very narrow rpm range, making them difficult to use for general-purpose applications.
[12:27:31] <SpeedEvil> Making your ~1m diameter turbine varying from 200 to 800C can have a .1mm gap to the case is fun
[12:27:52] <SpeedEvil> Over the whole operating range
[12:28:08] <furrywolf> turbines are definitely more efficient and simpler than my design... but have other issues.
[12:29:19] <archivist> coworker at a previous job left to start a turbine tip measuring company

[12:37:23] <furrywolf> bbl
[12:37:28] <SpeedEvil> Currently wondering the best way to go cheaply from ~20000RPM down to ~600 for a chain drive for a small cart.
[12:37:46] <zeeshan|2> epicyclic gear
[12:37:48] <zeeshan|2> s
[12:37:52] <furrywolf> best, cheaply... pick one.
[12:38:03] <zeeshan|2> how much input torque
[12:38:44] <Tom_itx> SpeedEvil reprap print a harmonic drive
[12:39:35] <SpeedEvil> furrywolf: yeah - I know. But I see no real reason I can't cut a gear for a chain drive out of some plate I have with a drillbit and file.
[12:39:51] <SpeedEvil> zeeshan|2: 500W
[12:40:26] <archivist> 20k rpm is a bit too much for chain methinks
[12:40:46] <archivist> trivial for helical gear
[12:41:02] <SpeedEvil> archivist: yeah - the chain goes from 600 to 60

[12:42:33] <archivist> and one in a clock I made
[12:43:54] <archivist> hidden inside the barrel http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_07_15_Webb_Clock/P1010006.JPG
[12:45:24] <zeeshan|2> nice!
[12:45:41] <archivist> and another in that winding motor as it happens
[12:46:04] <zeeshan|2> are those gears made out of brass
[12:46:30] <archivist> yes, inside the barrel is steel though
[12:47:06] <archivist> the worm squealed so tried a nylon
[13:03:25] <cradek> I love the socket head cap screws
[13:03:30] <cradek> very utilitarian
[13:03:54] <cradek> the motor just lifts the weight? is there maintaining power?
[13:06:12] <cradek> it has too many parts to be time-only and I don't see an escapement - what is it exactly? did you finish it?
[13:06:27] <cradek> it's beautiful
[13:12:56] <archivist> made the basic clock for customer to fit his self made gravity escapement
[13:13:51] <archivist> time only, weight maintained, but electrically wound with the power kept on by the gearbox in the barrel
[13:15:34] <cradek> wow
[13:15:44] <cradek> wish I could see it finished
[13:16:24] <cradek> I've only seen a couple running gravity escapements - they're so neat
[13:16:25] <archivist> I should call it weight driven and maintained
[13:16:36] <cradek> they don't sound like clocks
[13:16:47] <archivist> I have a vid he sent back
[13:17:08] <archivist> cant remember if its on this box
[13:23:30] <archivist> cradek, seems they are http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_09_17_web_cnc_worm/

[14:12:28] <archivist> furrywolf, an interesting engine design for you http://www.collection.archivist.info/archive/DJC/BK/BK346/
[14:12:43] <cradek> archivist: these are cool, anyway
[14:13:44] <archivist> cradek, I should find an editor and mangle these AVI files into something usable
[14:14:04] <cradek> archivist: I'd like to see them, but don't do it just for me
[14:14:44] <cradek> I've reencoded files with mencoder before
[14:14:53] <cradek> figuring out the command line is a task
[14:16:40] <archivist> heh
[14:17:55] <archivist> ew based on mplayer, which fails to play those files on this box anyway, totem works
[14:18:21] <cradek> yeah maybe not then.
[15:20:46] <Computer_barf> is it necessary to load the 7i76e mesa card with firmware to get it working or does it come loaded with firmware?
[15:26:18] <Computer_barf> MarkusBec: you around?
[15:33:04] <pcw_home> alway loaded
[15:34:04] <Computer_barf> pcw_home: was that a response to me?
[15:34:35] <pcw_home> no, I'm always loaded
[15:35:00] <Computer_barf> now im not sure if you are being sarcastic or just drunk
[15:36:04] <pcw_home> The 7I76E is preloaded with 7I76E firmware (in fact if it had no firmware you woudl need a JTAG programmer to recover)
[15:36:25] <Computer_barf> ahh
[15:36:32] <Computer_barf> cool so i don't have to do anything
[15:36:34] <Computer_barf> thats the way I like it
[15:36:42] <Computer_barf> cause I mostly don't know what im doing
[15:36:53] <Computer_barf> so a reduction in steps is appreciated
[15:36:58] <Computer_barf> if only i knew what to do next
[15:37:19] <Computer_barf> I do know that I likely have to power the thing so I'll do that I guess
[15:37:57] <Computer_barf> ive hooked up all my steppers to the 7i76e, still need to power the drivers
[15:38:06] <Computer_barf> set the dip switches
[15:38:13] <Computer_barf> wired the steppers to the drivers
[15:38:35] <Computer_barf> started printing standoffs on my 3d printer for the motherboard and mesa
[15:39:19] <Computer_barf> installed linuxcnc with the RT-prempt
[15:40:29] <Computer_barf> I imagine once I get the mesa board powered I will be powering my drives and then off to try to configure linux cnc
[15:44:05] <skunkworks> 7i76e looks really cool
[15:44:31] <Computer_barf> looks cool but for a noob it might have been easier to do something where I have actual instructions
[15:44:52] <skunkworks> eh - it is good for you.. :)
[15:44:54] <Computer_barf> people recommended it to me here , i suspect I will be happy once I get it working
[15:45:18] <pcw_home> do you have the latest linuxcnc ISO installed
[15:45:23] <pcw_home> ?
[15:46:36] <Computer_barf> yes I got that and updated the kernel per somones advise
[15:46:54] <Computer_barf> ok got it powered up
[15:47:06] <Computer_barf> some lights blinked and now just the power light is solid
[15:47:10] <pcw_home> do you have 2 Ethernet interfaces?
[15:47:13] <Computer_barf> suppose thats all well and good
[15:47:16] <Computer_barf> no
[15:47:17] <Computer_barf> lol
[15:47:22] <pcw_home> (or Ethernet and wireless)
[15:47:23] <Computer_barf> yes I'll be needing another one
[15:47:36] <Computer_barf> I figured that out once I had the board already here
[15:47:49] <Computer_barf> but I figure ill pick up a usb ethernet for the internet connection
[15:47:59] <Jymmm> Ewwwwwwwwwwwwwwwwwwwww
[15:48:05] <Jymmm> Nooooooooooooooooo USB
[15:48:13] <Computer_barf> well not usb for the mill
[15:48:25] <Jymmm> No usb to ethernet
[15:48:29] <Computer_barf> just for the occasionally used internet
[15:48:45] <pcw_home> I have a 1G USB-Ethernet adapter I found at goodwill for $3.00 and it works perfectly
[15:48:54] <Jymmm> You'll live up to your nickname with a usb nic =)
[15:49:05] <Computer_barf> I had a usb wireless dongle
[15:49:13] <Computer_barf> but the network didn't reach to the millhouse
[15:49:44] <Computer_barf> i don't see much of a problem for simple occasional network use
[15:50:14] <Computer_barf> I don't know what else I would put on this board for an additional ethernet port
[15:50:30] <Jymmm> What board?
[15:50:40] <pcw_home> USB-Ethernet is fine
[15:50:57] <Computer_barf> asrock q1900-itx
[15:51:38] <Computer_barf> if i was getting all purist I wouldn't be using the internet on the milling machine
[15:51:58] <Computer_barf> or browsing , or chatting
[15:52:49] <Jymmm> http://www.ebay.com/itm/IBM-Intel-PRO-1000-PT-QUAD-PORT-GIGABIT-ETHERNET-PCIe-NIC-Card-39Y6138-Low-Pro-/131491229769
[15:52:55] <pcw_home> I have > 1 year 24/7 time running real time Ethernet along with normal internet use, no problem
[15:53:38] <Jymmm> pcw_home: You could say that it makes you poop gold nuggets.... NO USB ETHERNET
[15:54:10] <Computer_barf> idk if I that board would fit my board, the only other slot that looks remotely like that is the empty ram slot
[15:54:13] <Jymmm> USB WIFI, sure, fine, just not ethernet
[15:54:22] <pcw_home> works fine for this
[15:55:08] <jthornton> what I'm down to now is figuring out how to set a root password and passing a key
[15:55:45] <Computer_barf> so I just started linux cnc for the first time
[15:56:09] <Computer_barf> I confronted with sample configurations , what might I select for setting up my g0704
[15:58:44] <pcw_home> If this is a odl 7I76e you may need to update the firmware
[15:58:53] <pcw_home> s/odl/old/
[16:01:44] <pcw_home> so first thing is to connect your Ethernet port to the 7i76E
[16:01:46] <pcw_home> and setup a static IP address on the host
[16:01:47] <pcw_home> If you have the default 7I76e address = both IP select jumpers down
[16:01:49] <pcw_home> I woudl set the host address to netmask
[16:04:32] <jdh_> can you just add a static arp entry pointing to the 7i76e MAC?
[16:04:55] <jdh_> (just out of curiosity, not to confuse whatever issue)
[16:06:36] <Computer_barf> I just got this one in the mail from mesa a few days ago
[16:08:04] <pcw_home> I guess so but you still need the interface setup
[16:09:44] <Computer_barf> so like, the thing has small web server on it?
[16:10:08] * furrywolf needs a 7i76e
[16:10:10] <Computer_barf> im flipping some jumpers and then going to the web server in the browser and changing some settings for a more ideal ip address
[16:10:28] <Computer_barf> furrywolf you should definantly get one, then tell me how to do everything, that would be sweet
[16:10:43] <jthornton> backuppc says it is backing up the Hardinge :)
[16:10:51] <furrywolf> Sure, send me yours, and I'll let you know exactly what it took to get it working. :)
[16:10:56] <Computer_barf> lol
[16:11:35] <pcw_home> no web server (theres all of 4K of code space (~2K used) on the 7I76e for the Ethernet interface)
[16:11:51] <zeeshan|2> http://i.imgur.com/asI7Zdp.jpg
[16:11:57] <zeeshan|2> i like my setup for this throttle body =)
[16:12:00] <Computer_barf> ok then how am I changing the ip address?
[16:12:01] <Jymmm> jdh_: I would HIGHLY recommend that you don't just "trust" your backups, but actually perform restores as a test as well.
[16:12:29] <pcw_home> did you read the 7I76E manual?
[16:12:53] <jthornton> looks good to me what are you doing to the throttle body?
[16:12:56] <furrywolf> I have the generic chinese hold-down set, but not those nice blocks you have under it...
[16:14:05] <Computer_barf> pcw_home, ive gone through it, but that doesn't mean i understand it
[16:14:09] <zeeshan|2> http://i.imgur.com/7gc2mJB.jpg
[16:14:23] <Deejay> gn8
[16:14:31] <zeeshan|2> jthornton: using that end mill im trying to bore out the throttle body
[16:15:09] <zeeshan|2> its a bit challenging
[16:15:11] <zeeshan|2> cause its 3 bores
[16:15:24] <zeeshan|2> so i just eyeballed the squreness of the tb to the table
[16:15:43] <zeeshan|2> and then used the indicator to find the center, (noting the locations of the readout)
[16:15:52] <zeeshan|2> and now writing a small g-code to bore them out
[16:15:59] <zeeshan|2> gonna start by removing 1mm from each bore
[16:16:34] <pcw_home> The 7I76E has 3 IP address options: W2 W3
[16:16:36] <pcw_home> fixed at DOWN DOWN
[16:16:37] <pcw_home> set by EEPROM (default = DOWN UP
[16:16:39] <pcw_home> BootP UP DOWN
[16:17:20] <furrywolf> are you making the butterflies too? if not, you need to get the bores to match the butterflies you bought...
[16:17:30] <zeeshan|2> yea im making the butteries for the large 2 ports
[16:17:44] <zeeshan|2> but using one of the order butterflies for the smaller port
[16:17:58] <zeeshan|2> currently the large ports are at 1.967" , the small port is at 1.772"
[16:18:03] <zeeshan|2> so im gonna make the small port 1.967"
[16:18:09] <zeeshan|2> and that butterfly _should_ work
[16:18:37] <zeeshan|2> and the 1.967 bores are becoming 2.175"
[16:18:47] <furrywolf> heh, just make sure you have enough metal left.
[16:18:57] <zeeshan|2> yea thats why im going in 1mm steps
[16:24:00] <Computer_barf> pcw_home: can't I just configure the ip addresses in PNCconf?
[16:24:21] <pcw_home> No
[16:25:07] <Computer_barf> ok so after I change the jumpers how do I actually change the address?
[16:25:38] <MarkusBec> rtfm :)
[16:25:39] <furrywolf> did you read the manual?
[16:26:55] <pcw_home> ok so if you set W2,W3 to down/up, the 7I76e IP address will be (you need to cycle the 7I76E power after moving the jumpers)
[16:26:58] <MarkusBec> page 27
[16:27:55] <pcw_home> Then you can setup your host ethernet port
[16:27:56] <pcw_home> (you can use the network mangler for this)
[16:29:04] <pcw_home> (there are more complete Ethernet setup instructions in the hm2_eth man page : man hm2_eth)
[16:29:06] <furrywolf> the manual says to use mesaflash --device 7i76e --set ip=whatever
[16:29:54] <pcw_home> yeah but thats not needed, the default IP address should be fine
[16:30:28] * furrywolf hands Computer_barf a copy of the manual
[16:30:45] <furrywolf> I don't even own one, and I've read it. :)
[16:32:35] <pcw_home> I presume the J1900 has RTK Ethernet chip and the MB MAC
[16:32:36] <pcw_home> if it has intel it needs to be tweaked with Ethtool
[16:32:50] <pcw_home> s/and the/as the/
[16:34:33] <pcw_home> the network manager icon is on the top right of the default wheezy screen and looks popsicle (why, I do not know)
[16:34:43] <pcw_home> looks like
[16:35:10] <furrywolf> lol
[16:39:02] <pcw_home> Computer_Barf: do you know how to setup an interface with a static IPV4 address?
[16:39:04] <pcw_home> If not, I can walk you through it (I have a laptop with Linuxcnc/Wheezy/Preemt-RT/HM2-Eth running a 7I92)
[16:40:14] <Computer_barf> pcw_home: i dont know much. lol. I
[16:40:22] <Computer_barf> I'll probably need a bit to be ready though
[16:40:26] <furrywolf> I haven't even turned on the laptop for my mill in months... need to work on the mill, which needs money.
[16:40:53] <pcw_home> That the one with a bent leadscrew?
[16:41:02] <furrywolf> yes. got that part working great.
[16:41:18] <Computer_barf> im currently wiring up the power to the drivers
[16:41:21] <furrywolf> oxytorch + hammer. :)
[16:41:49] <Computer_barf> do any of you put ferrite beads on your power lines?
[16:41:57] <furrywolf> http://fw.bushytails.net/milltest01.jpg
[16:42:38] <furrywolf> (the change in depth of cut was because I only clamped it at one end, and it rode up on the bit - not the mill's fault)
[16:43:56] <furrywolf> the mill is currently functional, but I need to build an enclosure for the electronics and re-wire it... right now the drivers, power supply, etc, are all loose parts sitting next to it. and I don't want to re-wire it until I have the right board to control it...
[16:44:27] <furrywolf> I can't actually use it, as it dumps swarf onto the breakout board... lol
[16:44:54] <pcw_home> I use (LARGE) ferrite beads for commom mode chokes for motor drives
[16:45:56] <pcw_home> so they always have 2 or 3 wires going through
[17:05:14] <Swapper> anyone that can explain how a Pneumatic counterweight works?
[17:05:18] <Swapper> https://www.youtube.com/watch?v=-D5FoXQOnPQ
[17:05:35] <Swapper> is it possible to do with a normal pressure regulator?
[17:05:43] <Tom_itx> probably like a shock absorber
[17:06:02] <Swapper> i need one to counterbalance my z axis
[17:06:18] <Tom_itx> or a spring or lead weight
[17:06:34] <Tom_itx> i used a big bronze bar to counterweigh mine
[17:07:01] <Swapper> i thaught it where a nifty way to counterpalance without taking up a lot of space
[17:07:21] <Tom_itx> my bar doesn't take much space
[17:07:28] <Tom_itx> it's on pulleys out of the way
[17:07:31] <Swapper> i need to counterbalance 80kg and dont have 80kg of brass/lead :)
[17:07:47] <Tom_itx> concrete in a bucket would also work
[17:07:55] <Swapper> that where my initial thaught, i even got the vgrove bearings to do that
[17:08:22] <Swapper> but then i found the Pneumatic counterweight method, and i have all the parts for it (if it works with a normal regulator)
[17:08:43] <Tom_itx> give it a go
[17:08:46] <Tom_itx> i dunno
[17:09:49] <Swapper> anyone have a good guide on how angular contact ball bearings should be oriented
[17:10:04] <pcw_home> not sure a simple regulator would work (where does the air go when Z moves down?)
[17:10:08] <Swapper> i know its been up for discussion here before
[17:10:47] <Swapper> pcw_home: my guess is that when the regulator gets a higher pressure on the "out" port it dumps it
[17:10:58] <pcw_home> or maybe with a big ballast tank
[17:11:08] <Swapper> yea you need a tank for it
[17:11:18] <Swapper> tu buffer the air volume
[17:11:26] <pcw_home> yeah
[17:11:28] <Swapper> s/tu/to
[17:11:47] <Swapper> but i dont get how the regulator can get the "dumped" air back in the tank
[17:11:58] <pcw_home> has the advantage of not doubling the Z axis mass like a counterweight
[17:12:10] <Swapper> yea that where my thaught also
[17:12:27] <Swapper> where thinking of using gas springs but they are not linear
[17:12:30] <Swapper> this should be linear
[17:12:42] <Swapper> and easier to tune with servo
[17:12:58] <Tom_itx> with the cylinder and reserve tank etc a bucket of concrete may take less space
[17:13:12] <Swapper> yea but it ads mass
[17:13:12] <Tom_itx> maybe not as elegant but effective
[17:13:26] <pcw_home> what about a big clock spring on the leadscrew :-)
[17:13:29] <Tom_itx> counter mass
[17:13:35] <Swapper> still more mass
[17:13:51] <Tom_itx> it's how elevators wowrk
[17:13:54] <Tom_itx> work
[17:14:06] <Swapper> yes but they dont accelerate like a cnc head do
[17:14:21] <Tom_itx> heh some of the ones i've been on seem to :)
[17:14:59] <Swapper> looks like the system needs 2 regulators...
[17:15:00] <Swapper> humz
[17:16:46] <asdfasd> constant pressure will work as linear spring while pressure is kept constant
[17:16:47] <asdfasd> probably some protection needed in case you loose pressure
[17:17:34] <Swapper> i run the mill without counterbalance today so thats no problem
[17:18:07] <Swapper> But how is it all connected, how would i build a constant pressure system that does not need a constant supply of air ?
[17:18:26] <Swapper> This dude seems to have built that https://www.youtube.com/watch?v=-D5FoXQOnPQ
[17:18:39] <Swapper> using 2 pressure regulators and a tank
[17:20:40] <furrywolf> a small cylinder and a large tank approximates constant pressure
[17:21:07] <Swapper> so no need for a regulator?
[17:21:29] <furrywolf> depends on how constant you need. heh.
[17:21:48] <furrywolf> the video will load in a few minutes so I can see what you're talking about.
[17:21:58] <Swapper> :)
[17:24:38] <furrywolf> I think the regulator is just for filling, and it's a small-cylinder-large-tank setup.
[17:25:00] <Swapper> oh ok, that makes it simple
[17:25:00] <furrywolf> consider that if the tank is 20 times larger than the cylinder, you'll only get a 5% change in pressure over the full stroke.
[17:25:18] <Swapper> ill have to try that
[17:25:27] <furrywolf> and he has a quite large tank.
[17:25:32] <Swapper> yea and then the regulator can keep it topped up
[17:25:34] <Swapper> if it leaks
[17:26:34] <furrywolf> I think the second regulator is for some part of the machine other than the counterweight.
[17:27:17] <Swapper> thank for the explanation
[17:27:32] <furrywolf> I'm not sure it is - I just think it is. heh.
[17:27:40] <Swapper> ill try it
[17:27:45] <Swapper> it sounds logical
[17:28:02] <furrywolf> the other option is just to build a quill drive, so you don't have nearly as much weight to move. :)
[17:28:06] <Swapper> the piston will "float" on the tank pressure
[17:28:44] <Swapper> the axis is allready working, i only want to offload some whight of the bearings
[17:28:57] <furrywolf> you probably also could do a pneumatic remote counterweight... get two matching cylinders, put one on the machine, and one next to it with the same amount of weight just sitting on it.
[17:29:01] <Swapper> i have a 2kw ac servo there so no lack of power
[17:29:05] <furrywolf> that'd be truely constant pressure
[17:29:51] <Swapper> i only need to get it somewhat counterbalanced
[17:30:06] <furrywolf> so just use a large tank. :)
[17:32:19] <furrywolf> if you figure his cylinder is 2.5" diameter and 2ft stroke (it's probably less, but just to approximate), that's about exactly a half gallon of volume. it looks like he has a 20-30 gallon air compressor tank with the pump removed. that's less than 2.5% pressure change over its full stroke.
[17:33:25] <Swapper> yea and thats not much compared to a normal gas strut
[17:33:35] <Swapper> i guess they are not that lienar
[17:33:40] <furrywolf> if I ever build a router, I'll use a quill drive... no reason to move the motor around!
[17:33:41] <Swapper> linear
[17:34:04] <Swapper> it for this mill https://www.youtube.com/watch?v=3aRGh76ApUs
[17:34:08] <Swapper> not a router
[17:35:10] <furrywolf> that looks like painfully much weight.
[17:35:45] <Swapper> yea.. and im second guessing my choice of bearings.. .:)
[17:36:12] <furrywolf> looks like you'll still have the tilting-forwards torque to deal with even with your support system.
[17:36:17] <Swapper> and in any case im thinking it would be good to counter its some
[17:37:10] <Swapper> tilting forward?
[17:37:39] <furrywolf> if you put your air cylinders back by the column, all they'll do is take the weight off the leadscrew. the bearings will still see the same forces.
[17:38:58] <furrywolf> or do you mean the leadscrew bearings, not the ones between the head and the column? (if any - just gibs?)
[17:39:21] <Swapper> its gibs, i mean the ballscrew bearings
[17:39:43] <furrywolf> ah
[17:40:39] * furrywolf is too used to people in here building things with ball bearings on rails
[17:41:51] <Swapper> i tore the z axis down "again" today since i have some weerd noise... dont know if its the bearings
[17:42:15] <Swapper> and im seccond guessing my self every time im asemling the angular contacts....
[17:42:22] <furrywolf> I'd love a nice large mill... mine has 3" of Z travel. heh.
[17:42:42] <zeeshan|2> well i just found out
[17:42:48] <Swapper> i had an X2 mill before this one.
[17:42:59] <Swapper> its quite the differance
[17:43:16] <zeeshan|2> my machine doesnt like a 3" axial doc .050" radial doc, 300 sfm, 8ipm with a 1" end mill
[17:43:21] <zeeshan|2> i think im deflectiung the end mill
[17:43:26] <zeeshan|2> mad chatter
[17:43:43] <furrywolf> cut faster?
[17:43:55] <zeeshan|2> i tried feeding slower and faster
[17:44:01] <zeeshan|2> didnt seem to change it
[17:44:04] <furrywolf> if it gets quieter, good. if it breaks the cutter, you know you were feeding too fast. :P
[17:44:54] <Swapper> deflecting a 1" end mill requires so serius torque ?
[17:45:09] <furrywolf> Swapper: he has real toys. :(
[17:45:27] <zeeshan|2> i think im gonna try helical plunging
[17:45:28] <Swapper> ill bet
[17:45:41] <Swapper> zeeshan|2: what material ?
[17:45:45] <zeeshan|2> aluminum
[17:46:24] * furrywolf bets the problem is the z axis driver. :P
[17:46:33] <zeeshan|2> haha
[17:46:39] <Swapper> nr of flutes?
[17:46:57] <zeeshan|2> 4
[17:47:23] <zeeshan|2> im prolly feeding too slowly
[17:47:29] <zeeshan|2> but i wanna take it easy
[17:47:59] <furrywolf> I think even your machine would have a hard time breaking a 1" endmill.
[17:48:18] <zeeshan|2> im afraid of breaking the throttle body
[17:48:20] <Swapper> 1500 rpm ?
[17:48:24] <zeeshan|2> the middle section is thin.
[17:48:38] <zeeshan|2> swapper , im at 1100 rpm
[17:48:53] <Swapper> carbide ?
[17:48:56] <zeeshan|2> no hss
[17:48:57] <furrywolf> ... you're machining the throttle body with a 1" endmill? lol
[17:49:03] <zeeshan|2> yes
[17:49:12] <zeeshan|2> i dont have a cat40 adapter for my boring bar yet
[17:49:24] <Swapper> 1987 rpm 38 in/min
[17:49:36] <Swapper> 1.9 hp
[17:50:01] <Swapper> sorry 2.4 hp
[17:50:13] <Swapper> at 3" depth
[17:50:33] <Swapper> Breaking Torque:687.87in-lb
[17:50:42] <Swapper> Cutting Force:151.27lb
[17:50:44] <furrywolf> Swapper: he's worried his workpiece can't handle that much energy input.
[17:50:58] <furrywolf> yes. 151lb will snap it.
[17:51:12] <zeeshan|2> http://i73.photobucket.com/albums/i225/nvmyre/throttlebody/16072008027.jpg
[17:51:17] <zeeshan|2> look at the wall between the two bores
[17:51:21] <zeeshan|2> im afraid to deform that
[17:51:28] <Swapper> Torque:75.6in-lb
[17:51:50] <Swapper> 21 in/min seems to be the calculated value
[17:51:52] <furrywolf> make shallower cuts rather than doing all 3" at once?
[17:51:57] <Swapper> at 1100 rpm
[17:52:02] <zeeshan|2> f urry yea im gonna do .1
[17:52:40] <furrywolf> if you break it, just put a sbc in. :P
[17:53:41] <furrywolf> sbcs fix all rotary issues. :)
[17:56:11] <zeeshan|2> haha
[17:57:50] <zeeshan|2> http://i.imgur.com/2lBW4Tq.png
[17:57:52] <zeeshan|2> helical bore time!
[17:58:39] <furrywolf> although a subaru EJ207 or a toyota 2ZZ-GE would match the stock handling a lot better...
[17:59:13] <furrywolf> ohh, doing all three at once. better have it lined up well. :P
[18:04:24] <furrywolf> meh. my stereo is unbalanced with one woofer removed. oh well.
[18:06:11] * furrywolf cranks up the bass to the other five
[18:08:10] <jdh_> what's playing?
[18:08:49] <furrywolf> right now, Breakdown Valentine - Surrender
[18:09:25] <renesis> youre running six sets of mid and high drivers?
[18:09:44] <furrywolf> I'm running six of everything. :P
[18:09:59] <renesis> well not woofers i guess
[18:10:19] <furrywolf> my living room is a stack of sansui sp-7500x (16" 5-way), sansui sp-3500 (14" 6-way), and pioneer cs-a700. (12" 3-way, one woofer sitting on my workbench)
[18:10:19] <renesis> do you move your head around to try and average out all the comb filtering?
[18:10:26] <furrywolf> lol
[18:10:30] <jthornton> the backup of the hardinge worked but the redirection did not
[18:10:39] <furrywolf> there's a noticable dead spot near the front door where the bass vanishes, but otherwise it's not too bad.
[18:10:50] <renesis> im not talking about the bass
[18:10:58] <Swapper> anyone know what sort of pump this is ? http://imagizer.imageshack.us/a/img208/5729/dsc0113wn.jpg
[18:11:27] <furrywolf> do you have a problem with my 28-way speaker stack? :P
[18:11:46] <renesis> when you go on and on about needed high quality digital files, kinda
[18:12:05] <renesis> youre murdering the sound =(
[18:12:07] <furrywolf> this is the party stereo, not the accurate listening stereo.
[18:12:40] <furrywolf> actually, it sounds better than either sansui pair does on its own... let's just say sansuis have... quirks.
[18:12:46] <renesis> the 10 lbs of cheap 70s and 80s capacitors and inductors stereo =\
[18:12:51] <Tom_itx> Swapper looks like a cheap diaphram pump
[18:12:59] <renesis> theyre 5 ways, how do they not have quirks
[18:13:08] <renesis> they prob had quirks new
[18:13:20] <Swapper> Tom_itx: does a diaphram pump have high pressure ?
[18:13:20] <furrywolf> yes, they did.
[18:13:34] <Swapper> so it could be used as a way oiler pump ?
[18:13:37] <furrywolf> I think sansui's motto is "we have room to cram another drive in!"
[18:13:39] <Tom_itx> probably not very high
[18:13:58] <furrywolf> or "let's cram another drive in down here!"
[18:14:19] <renesis> i think you should low pass everything at 100hz, and match to a decent pair of 2-way bookshelf speakers
[18:14:42] <renesis> sound better, bass will be bit clearer, and people wont know its not coming from all the old speakers
[18:15:17] <furrywolf> if I want high quality, that's what the JBL studio monitors are for.
[18:15:30] <Swapper> Tom_itx: my guess is a FUEL PUMP
[18:15:32] <renesis> but those are 30 years old =(
[18:15:43] <Swapper> http://www.ebay.com/itm/12V-ELECTRIC-FUEL-PUMP-UNIVERSAL-DIESEL-OR-PETROL-/261060771194?pt=LH_DefaultDomain_3&hash=item3cc86f3d7a&vxp=mtr
[18:15:54] <furrywolf> yes, and still better than anything you can get today for less than several thousand bucks. your point?
[18:16:04] <renesis> eh, probably not
[18:16:27] <renesis> my guess is $400 worth of active monitor speakers will out do them now
[18:16:38] <furrywolf> impressive. I got my 14.1V rail down to 12.9V. making it do some work. :P
[18:18:43] <renesis> surrender intro sounds like u2
[18:18:58] <renesis> is it going to do a thing?
[18:19:01] <renesis> oh
[18:19:07] <renesis> disco
[18:19:20] * furrywolf is now listening to Breakdown Valentine - Beautiful Distraction
[18:19:30] <furrywolf> it's disco, except now it's called "electronic dance".
[18:19:41] <renesis> its a house beat, house is disco
[18:20:04] * furrywolf is spending the time not talking to renesis doing housework, and wanted some good housework music
[18:20:35] <renesis> beautiful distraction has enough bass to fuckup my sub's post xover monitor out =\
[18:21:21] <furrywolf> funny. here, with my total garbage '70s speakers you hate, it has enough bass to make stuff on the floor bump around, without distorting.
[18:21:24] <renesis> i like this one better, appregiators are neat!
[18:21:56] <renesis> furrywolf: im not gonna defend the product designers decision to not use neutrik XLR
[18:21:59] <renesis> fuckin larry
[18:22:39] <furrywolf> also, just to piss audiophiles off, my speakers run on flat-4 trailer wire, not OFC speaker cable. :P
[18:22:58] <renesis> it has taken like 3 or 4 years of abuse to fail, and its a intermittent failure you can nudge to fix
[18:23:50] <renesis> meh, my favorite speaker cable that isnt SJ double insulated is is teflone covered silver tinned copper twisted with a drill
[18:23:57] <renesis> *teflon
[18:25:09] * renesis adjusts folded business card precision XLR shim
[18:25:12] <furrywolf> http://www.wholesalemarine.com/ancor-16-4-tinned-flat-boat-trailer-wire.html I bet you can't find anyone who can tell that apart from $1000 speaker wire in an blind test.
[18:25:48] * furrywolf randomly switches to Life of Agony - Justified
[18:25:56] <LeelooMinai_> It's not even cryogenically treated
[18:26:30] <renesis> furrywolf: a lot of the high end audiophool stuff is loaded up with parasitic capacitance
[18:26:40] <renesis> it drops out high end, and theyd be able to hear the diff
[18:27:06] <renesis> theyd still be idiots, but they would be right when they said your cables sounded bright and harsh in comparison
[18:27:16] <furrywolf> aka "better"
[18:27:36] <renesis> dunno, last octave is trash
[18:27:53] <renesis> fuck everything above 10khz
[18:28:16] <LeelooMinai> If you are old you probably cannot hear above that anyway:)
[18:28:24] <renesis> not much
[18:28:56] <renesis> im at like 16khz, some older acoustic engineers i work with are sab about only going up to 12khz or so
[18:29:10] <LeelooMinai> I tested my small nephew, myself and mom once - nephew - 18kHz, me 15kHz, mom 10kHz
[18:29:10] <renesis> i dont really give a fuck, theres not much useful up there
[18:29:33] <renesis> your brain doesnt use it for soundscape processing either, its too random
[18:30:09] <renesis> leeloominai: that seems pretty normal, it doesnt really matter listening to most music
[18:30:32] <LeelooMinai> Right
[18:30:50] <renesis> your daily ambient noise environment, and how your brain adapts to that, prob has a bigger impact as it does so in the middle of your hearing bandwidth
[18:31:22] <LeelooMinai> And how long ago you cleaned the ears:)
[18:31:30] <renesis> also can cause tinitus in extreme cases, which is super on topic in this chan
[18:31:47] <renesis> yeah that makes a diff, pressure equalization too
[18:32:05] <renesis> most acoustic guys i know pop their ears before before critical work
[18:32:25] <SpeedEvil> Flash-bangs are excellent for that.
[18:32:28] <renesis> like, fighter pilots and speaker geeks, practically the same thing
[18:32:31] <LeelooMinai> Sounds a bit extreme:)
[18:33:01] <renesis> speedevil: maybe if you have your mouth open
[18:33:06] * LeelooMinai imagines a guy howling in an industrial vacuum to the recording room and saying "Time for ear popping!"
[18:36:11] * furrywolf howls at the moon, not at vacuums
[18:36:51] <renesis> furrywolf: last track is best so far
[18:37:20] <furrywolf> which one?
[18:37:25] <renesis> real drummer plus wall of distortion and steady clean bass rawrararar
[18:37:36] * furrywolf has changed tracks an average of every 4 minutes or so
[18:37:37] <renesis> justified
[18:38:00] <furrywolf> plus their vocalist is a hot transgirl. :P
[18:38:35] <furrywolf> current random song is Stone Sour - Cardiff
[18:38:49] <renesis> pass on that
[18:38:50] <furrywolf> previous was Shinedown - Call for help
[18:39:37] <renesis> the stone sour, not bc transgirl
[18:40:02] <furrywolf> don't like stone sour? I'm not a huge fan of theirs, but they have a few good tracks.
[18:40:05] <furrywolf> this being one of them.
[18:40:42] <renesis> i honestly dont remember the music, i remember listening on not caring
[18:40:53] <renesis> *and not
[18:41:39] <furrywolf> they have some total crap too
[18:41:42] <renesis> hehe, shinedown sounds like they <3 aic
[18:41:58] <furrywolf> you could listen to this track and form your own opinion, of course. :P
[18:42:18] <renesis> shh, more shinedown
[18:42:43] <furrywolf> Raveonettes - Cops On Our Tail just came on. (now how's that for a genre switch?)
[18:44:01] <LeelooMinai> That's some scarry stuff...
[18:44:13] <renesis> which?
[18:44:20] <LeelooMinai> All of the above:)
[18:44:22] <renesis> aic inspired music?
[18:44:39] <renesis> ya totally =\
[18:44:58] <furrywolf> Dollyrots - Rock Control (yay another genre change)
[18:45:07] <LeelooMinai> I like AIC, but I do not see resemblance
[18:45:30] <renesis> furrywolf: all this stuff on the spotify, btw
[18:45:48] <furrywolf> yeah, I don't associate shinedown and aic either
[18:47:05] <renesis> the warbly vocals, mixing up slow bassy melodic bluesy stuff with grungy speed metal
[18:48:48] <furrywolf> Sisters of Mercy - No Time To Cry
[18:49:42] <renesis> shinedown - sin with a grin, 1:35, this is like paying respect to layne
[18:52:33] <furrywolf> Joan Jett - Fetish
[18:52:39] * furrywolf loves random
[18:55:21] <renesis> meh, back to dnbradio stream, bbl
[18:55:34] <furrywolf> Siouxsie And the Banshees - Nocturne - Night Shift
[20:22:26] * furrywolf flops down exhausted from doing too much housework
[21:23:16] <zeeshan> http://imgur.com/a/ffqCw
[21:23:18] <zeeshan> turned out pretty good
[21:23:23] <zeeshan> just need to lap the butterfly in
[21:23:33] <zeeshan> helical bore is the way to go!
[21:26:11] <furrywolf> my project for today was knocking down the cardboard pile for recycling. now I can reach the other side of the living room!
[21:28:57] <furrywolf> hand polished after milling?
[21:29:16] <zeeshan> yes
[21:29:42] <zeeshan> a boring bar woulda left a better finish
[21:29:43] <zeeshan> oh well
[21:30:20] <furrywolf> are there any other modifications to the engine? that throttle body doesn't look like a bottleneck for a stock engine...
[21:30:31] <zeeshan> it just helps response
[21:30:42] <zeeshan> those road course racers want every edge
[21:30:42] <zeeshan> lol
[21:31:52] <furrywolf> porting and polishing the intake runners too?
[21:32:03] <zeeshan> i didnt fully polish it
[21:32:05] <zeeshan> i left some mill marks
[21:32:11] <zeeshan> you want it to be turbulent
[21:33:24] <zeeshan> he only gave me the tb to modify
[21:37:28] <furrywolf> somehow it still seems like an exercise in making the engine need apex seals even more often. :)
[21:37:56] <zeeshan> lol
[21:41:07] <furrywolf> no one I know, out of about a half dozen rx7s, has had one running for more than 6 months.
[21:41:34] <zeeshan> so true man
[21:41:41] <zeeshan> jackstand racing!
[21:41:43] <furrywolf> now, this is about six times longer than an air-cooled VW, but it's still not that great.
[21:41:58] <zeeshan> air cooled vw's are unreliable?
[21:42:00] <zeeshan> i didnt know that :)
[21:42:27] <archivist> the cranks break if you hit resonance
[21:42:35] <zeeshan> haha
[21:42:59] <Rab> "Unreliable!" "Easy to rebuild!" "Unreliable!" "Easy to rebuild!"
[21:43:38] <furrywolf> lol
[21:46:18] * furrywolf prefers engines that are more work to rebuild, but don't need it monthly
[21:47:26] <zeeshan> rotaries arent too bad if theyre naturally aspirated
[21:48:21] <archivist> "naturally aspirated" = in parts on the bench
[21:48:29] <zeeshan> haha
[21:50:38] <furrywolf> lol
[21:51:09] <zeeshan> i think the reason why i dislike rotaries is not the possiblity of seal failures, but the fact that if you do blow an apex seal, it goes and spits it into your turbo chipping your turbine wheel, destroying the rotor and rotor housing. replacing these gets stupid expensive. its not like a piston engine where when you blow a ring, you can just rebore or possibly rehone and throw some new pistons in.
[21:51:30] <zeeshan> a rotor is about 600 bux, a rotor housing is 1100
[21:52:01] <furrywolf> ... or just put a new ring in. or, even better, a piston from another engine that still has rings on it.
[21:52:07] * furrywolf is a redneck, remember? :P
[21:52:10] <zeeshan> haha yea
[21:52:17] <zeeshan> sometimes that is all that is needed
[21:52:53] <furrywolf> yes, on rotaries any failure at all tends to destroy pretty much every part of the engine...
[21:53:00] <zeeshan> yep =/
[21:53:06] <zeeshan> you cant even fix the rotor housing reliably
[21:53:21] <zeeshan> the rotor sometimes you can machine off the high spots and it might work
[21:53:31] <furrywolf> and aren't they nitrided, so any damage or wear removes the coating and you're screwed?
[21:53:56] <zeeshan> yea a scratch means game over
[21:54:42] <zeeshan> its kinda cool how they make the rotor housing
[21:55:23] <zeeshan> they have a cast iron inner lnner which has fine teeth all along its outer perimeter. then they put that in a mold and pour aluminum in
[21:55:37] <zeeshan> lnner = liner
[21:56:37] <furrywolf> they make piston engines like that too.
[21:56:52] <furrywolf> except for some old ones with pressed-in liners
[21:57:46] <archivist> chainsaw engines and other crap only get a sniff of liner material
[21:58:21] <furrywolf> and abc engines don't get liners. :P
[22:50:53] <zeeshan> its quiet in here
[22:51:11] <zeeshan> you guys arent doing actual work are you :-)
[22:51:12] <furrywolf> yes
[22:51:33] <zeeshan> i wish whoever hand ported this throttle body
[22:51:35] <zeeshan> didnt do it
[22:51:39] <zeeshan> i coulda machined it using a ball nose
[22:51:43] <zeeshan> and made it look pretty
[22:52:00] <Tom_L> sry can't talk.. too busy..
[22:52:05] * Tom_L goes back to snoring
[22:52:15] <zeeshan> Tom_L: ;[
[22:52:27] * furrywolf is taking a break from housework to eat a salad bowl
[22:52:35] <Tom_L> still adjusting mb settings
[22:53:07] <furrywolf> listening to The Pandoras
[22:53:36] <zeeshan> you mentioned a song earlier
[22:53:38] <zeeshan> what was it called
[22:53:43] <zeeshan> it sounded familiar
[22:53:54] <furrywolf> I mentioned several earlier. lol
[22:54:01] <zeeshan> blah ;p
[22:56:11] <furrywolf> umm, what did I listen to and tell renesis? Breakdown Valentine - Beautiful Distraction, Siouxsie - Night Shift, Shinedown - Call for help, Sisters of mercy - no time to cry, joan jett - fetish, life of agony - justified, the prids - back up slow, stone sour - cardiff, raveonettes - cops on our tail, the pandoras - craving, umm...
[22:56:37] <zeeshan> Breakdown Valentine - Beautiful Distraction
[22:56:37] <zeeshan> thats it
[22:57:25] <zeeshan> nope, this wasnt the song i thought it was
[22:57:27] <zeeshan> :p
[23:01:28] <furrywolf> wall of voodoo - big city, renaissance - mother russia, the trims - around the sun, disturbed - ten thousand fists, ozzy - trap door, black sabbath - paranoid, heaven and hell, guilty as hell, heaven and hell - bible black, dokken - dream warriors, the setting son - eat my fear, bronx casket co - no miracles, alice in chains - grind, boss martians - kill my telephone, dream theater - build me up, break me down, flotsam and jetsam - play yo
[23:01:36] <furrywolf> I don't rememeber everything that's come up tonight. :P
[23:03:32] <furrywolf> freedom call - freedom call, garbage - I think I'm paranoid, in this moment - adrenalize, the dollyrots - rock control, ...

[23:13:49] * furrywolf has been listening to music all day, and can't remember everything that's played
[23:15:58] <furrywolf> overall a good assortment of housework music. I skipped many tracks that, while good, weren't quite right for hard work.
