[02:24:15] <Deejay> moin
[03:25:46] <XXCoder> finally
[03:25:53] <XXCoder> aliexpress seller contacted me
[03:26:09] <XXCoder> 86.30 for 52mm spindle compitable z block
[03:26:19] <XXCoder> worth it as its much stronger than any other method
[05:21:35] <nubcake> Hey yall
[05:22:16] <XXCoder> hey
[09:54:48] <enleth> a modern take on a classic solution for detecting unsafely low oxygen levels: equip a canary cage with a thermal camera and some OpenCV to continuously check if the canary is alive, then sound the alarm when it dies
[09:55:07] <enleth> automated feeding can be integrated as well
[10:06:59] <tiwake> better haul butt when it doe
[10:07:01] <tiwake> does
[10:07:48] <enleth> I'm sure that's what they did back in the days they actually used canaries for this
[10:08:33] <tiwake> now its open pit mines, so less of an issue
[10:09:46] <enleth> on a more serious note - I'm looking for photos/diagrams of horizontal bandsaw blade guides, but all I can find is Gingery's bandsaw book
[10:10:10] <enleth> I'm inclined to actually buy it, but it would be nice to have some alternatives for inspiration
[10:10:13] <enleth> know anything?
[10:10:20] <tiwake> you mean for design?
[10:10:36] <tiwake> or the guides to keep the blade in place
[10:10:55] <archivist> go down to a local hardware place and stare at the crappy guides and how not to do it
[10:11:00] <enleth> I mean I'm considering building a horizontal bandsaw from scratch and the only part I don't know how to make are the blade guides
[10:11:11] <enleth> the ones that twist the blade into the cutting plane
[10:12:13] <tiwake> its just a couple of posts on either side of the cutting area, with generally hardened steel or sometimes carbide pads to hold the blade
[10:12:44] <archivist> better ones have rollers
[10:12:59] <archivist> adjustable rollers at that
[10:13:00] <tiwake> donno if I would call those better...
[10:13:07] <enleth> do they use several sets of pads in series, each at a successively steeper angle?
[10:13:12] <tiwake> carbide pads are pretty nice
[10:13:27] <tiwake> don't have to worry about chips getting in the bearings
[10:13:40] <archivist> the thickened weld section has to get through
[10:14:30] <enleth> I even found some photos of an Ellis brand bandsaw that twists the blade full 90deg
[10:14:52] <enleth> as opposed to the 45-something degrees in the chinese saws
[10:14:52] <tiwake> enleth: no, just sandwiching the blade to hold it at an angle different to what the blade wants to be, and hopefully vertical to the cutting surface
[10:15:47] <enleth> interesting - do you think even the 90deg twist can be safely done without extra guides at intermediate angles?
[10:16:09] <archivist> use a slitting saw blade, no bending needed
[10:16:28] <tiwake> enleth: why not build a cold saw instead?
[10:16:43] <enleth> archivist: it kind of stops being a bandsaw at that point
[10:16:57] <archivist> yes and gets a nice cut
[10:17:00] <enleth> tiwake: that's actually a good question
[10:17:19] <tiwake> a cold saw is better for automation, faster, etc. etc.
[10:17:27] <archivist> slitting saw being a cold saw :)
[10:17:27] <tiwake> nice square cut
[10:18:05] <tiwake> spin it at about 100 RPM and push hard
[10:18:28] <archivist> lathe abuse as a saw http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_04_17_Southbend_lathe/IMG_1796.JPG
[10:18:48] <enleth> I haven't been able to actually figure out the pros and cons of the three saw types used for cutting long stock (bandsaws, reciprocating saws and cold cut circular saws)
[10:19:01] <enleth> I've even had this discussion with some people here at least once
[10:19:18] <tiwake> well
[10:19:21] <enleth> and there seem to be as many proponents of bandsaws as cold cut saws
[10:19:38] <enleth> (with everyone agreeing that reciprocatings saws are a thing of the past)
[10:19:44] <archivist> I have a bandsaw and generally hate it
[10:19:45] <tiwake> everything that I've seen, one off stuff tends to be cut in a bandsaw, production tends to be in a cold saw
[10:20:18] <tiwake> not sure why honestly
[10:20:28] <enleth> I have to say, I was quite impressed with the cold cut saw used by the Make It Extreme guys
[10:20:33] <archivist> I can take a bigger cut with cold saw in the horizontal mill
[10:21:43] <tiwake> enleth: a guy who I made parts for, well the company but the guy designed it... made a cold saw for their walking bed floors... I made a lot of the custom parts for it so they could get nice square cuts
[10:22:31] <archivist> also much longer cuts that way http://www.collection.archivist.info/archive/DJCPD/PD/2011/2011_07_13_Adcock_and_Shipley/IMG_1139.JPG
[10:23:27] <tiwake> enleth: honestly I'd vote to have a cold saw... do it correctly and gear it down in addition to putting a variable frequency drive in
[10:23:37] <enleth> archivist: your server's somewhat slow or something
[10:23:59] <archivist> enleth, always, it is adsl
[10:24:38] <enleth> archivist: eugh. get a VPS or something to mirror it on
[10:24:50] <archivist> who pays?
[10:24:56] <tiwake> ^
[10:25:02] <tiwake> home servers ftw
[10:25:06] <archivist> I have no fucking money
[10:25:17] <tiwake> keep the data yours
[10:26:06] <archivist> done ever be rude to volunteers, not nice
[10:26:10] <archivist> dont
[10:26:37] <enleth> archivist: ok, that's a fair point, I don't think there are any free services suitable for the amount of data you have
[10:26:51] <enleth> tiwake: if it's all intended to be published, it's no less "yours" on a hosting service
[10:27:12] <enleth> tiwake: I'd agree with this sentiment for private data hosting
[10:27:17] <tiwake> enleth: they still have rules for the kind of data hosted on a service like that
[10:27:38] <tiwake> not that anyone actually cares
[10:27:45] <enleth> for VPS, yeah. you get a dedicated box if you want to publish anything you like.
[10:27:46] <tiwake> sometimes they do though
[10:28:22] <enleth> then they don't care unless it's some major bittorrent seeding of unlicensed stuff
[10:28:42] <enleth> it does cost at least $10/month, though
[10:29:30] <enleth> anyway, now I've seen about the same amount of people speaking in favor of bandsaws and cold cut saws
[10:30:24] <tiwake> enleth: I looked at the same thing, except in context of automation, cutting thousands of parts for a thing I used to make
[10:31:15] <tiwake> talked about automating the WF wells bandsaw there, but why bother when a cold saw could be built for a little more effort and a lot nicer results
[10:32:45] <tiwake> you should be able to cut a wider variety of materials too
[10:34:18] <enleth> tiwake: well, my use case is definitely prototyping and one offs - again, the kind if stuff Make It Extreme guys do, if you know them, look them up if you don't
[10:34:50] <enleth> it's actually interesting that, as you said, bandsaws seem to be more common in prototyping
[10:35:10] <tiwake> thats not quite what I said
[10:35:27] <enleth> maybe it's just inertia? that's what amateurs and job shops always had, before cold cut saws came to be, so that's what they keep on using?
[10:35:28] <tiwake> bandsaws seem to be used in one-off parts
[10:36:44] <tiwake> the steel supply shops I've talked to have both, they tend to use the bandsaw for one off cuts, and cold saw for production blank cutting
[10:36:53] <enleth> interesting
[10:37:36] <tiwake> it could be the only reason why is cause they've always used a bandsaw, and now they have customers asking for production cut blanks, so they get the shiny new badass coldsaw
[10:38:09] <tiwake> place I worked at had a smallish one-off coldsaw
[10:38:17] <tiwake> and a bandsaw
[10:38:34] <tiwake> didnt have a nice way to measure the length of stuff though
[10:38:44] <tiwake> *shrug*
[10:38:50] <tiwake> used both of them
[10:38:54] <tiwake> a fair amount
[10:39:23] <tiwake> anyway, gotta go
[10:39:43] <enleth> ok, thanks for the input
[11:13:03] <enleth> http://weldingweb.com/showthread.php?445211-DIY-cold-cut-saw - this thread is pure gold
[11:24:44] <archivist> I have also chucked a metal blade for al on my mitre saw, that works too :)
[11:26:01] <enleth> it's a shame I need it for steel
[11:26:45] <_methods> https://www.amazon.com/Makita-LC1230-12-Inch-Metal-Cutting/dp/B00004YOLV
[11:28:08] <archivist> some of those are abrasive disk cutters
[11:28:14] <_methods> not that one
[11:28:20] <_methods> its carbide toothed blade
[11:28:25] <_methods> for cutting ferrous
[11:28:44] <archivist> the real deal
[11:28:50] <_methods> yeah i love mine
[11:29:06] <_methods> cuts thru 2x2x1/8 wall tubing like wood
[11:29:58] <archivist> 40 odd years ago the day job had me using a dewalt overarm on al
[11:30:48] <archivist> my tinnitus is probably from that or going to see Hawkwind
[11:31:05] <_methods> yeah its not a quiet operation
[11:31:37] <sync> thw slow running ones are very nice
[11:34:54] <sync> oh wow enleth
[11:51:21] <enleth> sync: that thread?
[11:51:41] <enleth> _methods: oh, I haven't seen that one, only the abrasive wheel version
[11:52:08] <_methods> yeah much better than abrasive
[11:52:15] <_methods> the blades are just expensive
[11:52:44] <enleth> the whole thing isn't exactly cheap, but it's not really expensive either
[11:53:06] <enleth> seems manageable and it's makita, not a chink
[11:53:06] <sync> yeah enleth
[11:53:15] <_methods> well i think even a cheap bandsaw will cost you about $300
[11:53:15] <enleth> sync: it gets really good by page two
[11:53:26] <_methods> don't buy the morse one
[11:53:30] <_methods> we just bought one at work
[11:53:39] <_methods> and the blade guards broke after 2 days of use
[11:53:42] <sync> http://althaus-maschinen.com/maschinen/187/500x498/6.jpg
[11:53:46] <sync> that is the right thing to get
[11:55:54] <CaptHindsight> looks rigid :) http://i185.photobucket.com/albums/x175/pns112500/Mobile%20Uploads/1402409348_zpsa8c9573a.jpg
[11:56:30] <CaptHindsight> I'd be careful standing next to it when it's off
[12:02:00] <enleth> the guy said he doubled the arbor nuts after the blade flew off with just one nut holding it
[12:02:21] <_methods> safety first
[12:02:23] <_methods> lol
[12:02:27] <CaptHindsight> was he running the motor backward?
[12:02:35] <enleth> it'd say it's a nut case either way
[12:03:39] <SpeedEvil> If it was too loose, and stopped suddenly?
[12:03:48] <CaptHindsight> I never see deals on used cold saws
[12:04:15] <CaptHindsight> unless $1k is a deal, they run $5k and up new
[12:04:43] <enleth> CaptHindsight: you mean the proper nice and beefy ones for industrial use?
[12:05:12] <CaptHindsight> enleth: yes, the miter saws for carpenters turned metal noise makers
[12:05:20] <CaptHindsight> not the
[12:05:44] <CaptHindsight> http://chicago.craigslist.org/nwc/tls/5761375347.html
[12:07:14] <CaptHindsight> hey I just found a deal http://madison.craigslist.org/tls/5779501452.html $350
[12:09:55] <archivist> be aware of the alloy window frame cold saws made in Italy, higher rpm and not so rigid
[12:10:25] <archivist> that last one in madison looks a bit like those
[12:10:38] <CaptHindsight> plus it's missing parts
[12:16:55] <archivist> pegic http://www.collection.archivist.info/searchv13.php?searchstr=herron+saw+PD
[12:25:16] <CaptHindsight> http://milwaukee.craigslist.org/atq/5783654421.html Mattel Power Shop - $20
[12:28:48] <CaptHindsight> looks like by 1978 kids became too irresponsible to work with power tools
[12:29:31] <archivist> dont want them to be damaged!
[12:29:46] <archivist> you dont learn without some pain
[12:31:31] <enleth> darwimism as a parenting strategy fell out of favor
[12:33:29] <IchGucksLive> hi
[12:33:56] <CaptHindsight> vas ist los?
[12:34:58] <CaptHindsight> IchGucksLive: are you un-retiring?
[12:35:02] <IchGucksLive> need to install all systems from 10.04
[12:35:09] <IchGucksLive> lots of time goeas on
[12:35:30] <IchGucksLive> also CUDA gas changed suport for GPU grafikkards
[12:35:39] <CaptHindsight> IchGucksLive: the major change to Linuxcnc is the new trajectory planner
[12:35:41] <IchGucksLive> so all systems are miss setup
[12:35:50] <IchGucksLive> i see
[12:36:02] <IchGucksLive> got the latest on 12.04 running
[12:36:02] <archivist> a cut finger is hardly darwinism
[12:36:35] <IchGucksLive> and Nvidia are a hell
[12:41:34] <CaptHindsight> http://chicago.craigslist.org/wcl/atq/5776076810.html features genuine cowhide drive belt
[12:42:25] <CaptHindsight> archivist: any guess on the era it's from? ^^^
[12:43:04] <archivist> 20's to 40's mebe
[12:43:42] <archivist> a bit over priced
[12:44:20] <CaptHindsight> CL prices tend to be 2X what they eventually sell for
[12:45:24] <IchGucksLive> overprised is good i loked at gforce gtx cards and they burn in to your pocket
[12:46:05] <CaptHindsight> http://racine.craigslist.org/hvo/5698697541.html and older one
[12:58:14] <archivist> who done it
[12:58:17] <IchGucksLive> im off bye
[13:03:04] <archivist> for fixing little stuff http://www.ebay.co.uk/itm/122138217730
[13:45:27] <dioz> anyone in here own a wood thickness planer?
[13:45:54] <archivist> probably many, ask a better question
[13:46:31] <dioz> you ever gone done and put some wood through one of them there wood thickness planers?
[13:47:09] <dioz> fuck one of them would be handy i figure
[13:47:38] <dioz> i remember there was one at the highschool
[13:48:17] <dioz> fuckin wood workers 'eh?
[13:49:47] <archivist> dont need to own one to have used one either
[13:52:08] <archivist> we used one to repair a clock bell enclosure, very easy and quick for a reasonable job
[13:53:19] <archivist> new wood around edge http://www.collection.archivist.info/archive/DJCPD/PD/2002/2002_10_10_Proof_house_clock/PA080383.JPG
[13:53:21] <dioz> like i need a 1 and 1/4" by 7 3/4" piece of wood
[13:53:24] <dioz> that's ~7' long
[13:53:29] <dioz> and i don't wanna double up
[13:53:34] <dioz> but it looks like i'mma have to
[13:54:46] <dioz> HF lumber
[13:55:21] <dioz> fuckin dewalt sells a 12" planer
[13:55:46] <dioz> for like $500 CAD
[13:55:52] <dioz> idk if i need it that much
[13:56:44] <dioz> i need physics 30
[13:56:47] <dioz> which is also $500
[13:57:01] <dioz> all these $500 add up
[13:57:54] <dioz> i've seen industrials upto 24" idk how much bigger they can get
[13:58:03] <dioz> i imagine substantially
[14:01:06] <dioz> fuckin... you ever hit your thumb dead on with a hammer and have it pop instead
[14:01:14] <dioz> it split like a grape
[14:02:27] <dioz> dude i know was wearing gloves on a mill and caught his glove and now lacks a thumb
[14:03:01] <dioz> i seen the head fly off a hammer and hit a dude in the face
[14:03:07] <dioz> he then proceeded to fall off the roof
[14:03:14] <dioz> it wasn't lulz
[14:04:16] <tiwake> that sounds horrible
[14:04:22] <tiwake> where you work
[14:04:25] <dioz> on pipeline we'd shoot a pig attached to a wireline through kilometers of pipe
[14:04:52] <dioz> the pig would come through with enough force that they'd put the track hoe bucket infront of the pipe to prevent it from shooting across the field and shit
[14:04:59] <dioz> dragging a fat cable behind it
[14:05:14] <dioz> one time it broke one of the teeth off the hoe bucket it hit so hard
[14:09:04] <witnit> dioz: you put images in my head like a stephen king book. You put Mike Rowe to shame.
[16:33:17] <Deejay> gn8
[17:18:40] <nubcake> gn8 everyone
[17:37:14] <pfred1> I think it was my keyboard that was flaking out on me
[18:18:30] <Duc> must say I never care to visit DC again
[18:19:02] <pfred1> what happened?
[18:19:18] <pfred1> I was in DC once during a Black Power rally that was weird
[18:19:39] <Duc> little crowd and small small places to live
[18:19:56] <pfred1> I wasi n that park by the washington monument and busload after busload of black folks just kept coming and coming
[18:19:56] <Duc> Im used to a 1/2 acre lot with 1800 sqft in just a rental house
[18:20:09] <Duc> that would be a little weird
[18:20:17] <pfred1> yeah being as I'm pale as a sheet
[18:20:31] <pfred1> I donno no one hassled me or anything
[18:20:35] <malcom2073_> I'm not a fan of cities, but DC probably the least
[18:20:46] <Duc> the Metro was nice but still
[18:20:49] <pfred1> there's stil la lot to see in DC all the museums
[18:20:56] <malcom2073_> I only live like two hours north, so we go there for the museums and all
[18:20:59] <pfred1> the smithsonian
[18:21:00] <Duc> wasnt to keen on walking to places to eat
[18:21:23] <Duc> but the smithsonian were disappointing. Much better meseums out there
[18:21:30] <pfred1> I haven't been to DC from here it is probably about 2 or so hours away
[18:21:45] <pfred1> but it is west of me
[18:22:01] <Duc> only cool one was the american history and that was the first floor with the electronics and old stuff
[18:22:24] <pfred1> heh if i want to see old electronics i can just look around me
[18:22:43] <pfred1> I need a new PC for my controller PC
[18:22:46] <malcom2073_> You should go to the national electronics museum, it's pretty cool
[18:22:48] <malcom2073_> bunch of old coldwar stuff
[18:23:02] <pfred1> I'd go if they let me strip parts
[18:23:09] <Duc> where was that at?
[18:23:10] <malcom2073_> I go there about once a year, they have a swap meet
[18:23:15] <malcom2073_> Bunch of old guys bring bunch of old stuff :-P
[18:23:17] <pfred1> oh yeah>?
[18:23:24] <Duc> the industrial musuem was closed
[18:23:27] <pfred1> now you're talking
[18:23:46] <malcom2073_> pfred1: http://www.nationalelectronicsmuseum.org/Techno-Swap-Fest.shtml
[18:23:48] <malcom2073_> Once a year, in Feb.
[18:24:15] <pfred1> oh maryland that's not too far from me
[18:24:40] <pfred1> I live in delaware
[18:24:47] <malcom2073_> Ah cool
[18:24:53] <pfred1> so some of maryland is real close by
[18:24:58] <malcom2073_> how far is Lorton from you?
[18:24:59] <malcom2073_> VA
[18:25:23] <Duc> I guess Ive been spoiled with the space museum in Huntsville and the nuclear museum in albuquerque NM
[18:25:27] <pfred1> ;et's see what google says
[18:25:33] <malcom2073_> Machinest yard sale next weekend: http://www.cams-club.org/events/yardsale2016.html
[18:26:53] <pfred1> 142 miles
[18:27:22] <malcom2073_> Hah wow nm
[18:27:23] <pfred1> well via this other route it is 133 miles
[18:27:42] <Duc> that could be a dangerous yard sale
[18:27:46] <pfred1> time is about a wash between the two about 2 and a half hours
[18:28:09] <malcom2073_> Duc: It is.
[18:28:35] <pfred1> what's it in camden?
[18:29:19] <Duc> malcom2073: if only I was closer
[18:29:41] <malcom2073_> No, Lorton
[18:29:56] <Duc> I could use a DRO for the lathe or even spare parts
[18:30:09] <pfred1> yeah I'm in the middle of nowhere out here it takes me an hour and 45 minutes just to get hte the edge of civilization from here
[18:30:20] <malcom2073_> Duc: Most of sthe stuff there is older
[18:30:23] <malcom2073_> not much newer than 1960
[18:30:33] <malcom2073_> Lots of tooling though
[18:30:51] <pfred1> I just picked up a jacobs 36 chuck for $3
[18:31:03] <pfred1> I thought that was pretty cheap
[18:31:05] <Duc> that would make it worth it
[18:31:18] <malcom2073_> Yeah
[18:31:25] <pfred1> it was a little stiff but i oiled it up and it is runnign smooth now
[18:32:03] <pfred1> when I do find tooling used it is uaually dirt cheap
[18:32:25] <pfred1> like i picked up a 2 inch R8 shell mill for $2
[18:33:32] <Duc> I could use some 2j collets
[18:33:40] <pfred1> I paid heavy for these http://i.imgur.com/wpXgLtq.jpg
[18:33:54] <pfred1> $20 but when I saw then I had to have them
[18:34:15] <pfred1> I used them when I was setting my CNC machine up too they were handy as hell
[18:35:12] <pfred1> full and new that set probably cost thousands
[18:35:33] <CaptHindsight> oops https://www.youtube.com/watch?v=fxouNcZGrE4 needed a heavier forklift
[18:35:39] <pfred1> it had all these warnings on it about breaking the seal
[18:35:39] <Duc> gage block set?
[18:35:44] <pfred1> yeah
[18:36:44] <Duc> was that your machine?
[18:36:50] <pfred1> what machine?
[18:37:16] <Duc> pfred1: I managed to score a collete pin gage set from place we were closing up to 3/4
[18:37:25] <Duc> CaptHindsight's video
[18:37:33] <pfred1> I don't know
[18:37:49] <CaptHindsight> Duc: nope
[18:38:52] <pfred1> this is my machine http://i.imgur.com/t75QZEc.jpg
[18:38:56] <malcom2073_> Haha, forklift operators
[18:39:02] <pfred1> it is like a $200 special
[18:39:27] <pfred1> I picked up the drawer slides for it at a yard sale for $5
[18:39:32] <pfred1> they're Accurides!
[18:39:56] <malcom2073_> haha nice
[18:39:58] <malcom2073_> Hey, it's a start!
[18:40:02] <malcom2073_> Use it to make yourself a better one now
[18:40:07] <pfred1> mah for what i do its fine
[18:40:18] <enleth> malcom2073_: well that's what you get for leaving stuff so long in the air, it was like doing a "look ma! no hands!" then crashing into a wall
[18:40:23] <pfred1> it is just a router
[18:40:27] <malcom2073_> Haha yep enleth
[18:40:32] <malcom2073_> Should've dropped as soon as that truck pulled out
[18:40:44] <Duc> I need some accurides for my gun safe
[18:41:13] <pfred1> the ones i got came out of aome kind of an equipment cabinet because they have these lips to go over sheet metal on them
[18:41:51] <pfred1> that only posed a problem mounting one of them though I had to route a groove in one of the Y axis 2x4s so it'd fit
[18:42:04] <pfred1> so not really a problem
[18:42:47] <pfred1> I went with the opposing slides design
[18:43:14] <pfred1> so it would always be hanging onto at least one slide at all times
[18:43:16] <enleth> malcom2073_: I'd have lifted that from the back of the truck instead of the side and have the driver pull out just enough to clear the truck bed by an inch and no more, then engage the parking brake - to have *something* to stop all that crap if it decides to tilt
[18:43:30] <malcom2073_> Always better ways
[18:43:31] <malcom2073_> always
[18:43:39] <enleth> wouldn't be pretty, but it would be prettier
[18:43:51] <enleth> I'd prefer to pay for a new truck fender than a new mill
[18:44:41] <pfred1> I just have an RF-32 bench top mill so it is not hard to move
[18:45:25] <pfred1> http://i.imgur.com/rHGhZ.jpg
[18:46:14] <pfred1> whenever i move it I'm glad it is not a Bridgeport then
[18:47:10] <enleth> pfred1: at least bridgeports are easy to take apart
[18:47:32] <pfred1> I've moved those too but all in one piece and just dragging them across shop floors
[18:47:56] <enleth> an enclosed VMC probably takes more time to take off all the damn panels and covers and whatnot than it does to disassemble a whole bridgeport and put it back together
[18:48:04] <Duc> probably true
[18:48:22] <Duc> I do need to make a enclosure for my bridgeport to reduce the dam chips and coolant everywhere
[18:48:40] <pfred1> just put shields in the t slots
[18:49:02] <pfred1> you can just use bits of sheet metal
[18:49:03] <Duc> still get everywhere when using flood or air
[18:49:16] <Duc> tried to do that but floor was soaked
[18:49:27] <pfred1> well it ain't 100%
[18:49:43] <pfred1> but you can catch most of the stuff flying around
[18:49:52] <Duc> it got alot of the stuff but still
[18:49:56] <enleth> Duc: try transparent cold room door curtains and find a coolant pan that fits your mill
[18:50:25] <pfred1> we had a mill with a chip pan that you had to walk on to operate the mill
[18:50:49] <pfred1> that machine was gigantic
[18:51:23] <enleth> pfred1: did you have to wear wellingtons to wade through the coolant?
[18:51:30] <pfred1> nah
[18:51:45] <pfred1> the cutter spun so slow it really didn't sling stuff around
[18:52:04] <Duc> this was a nice enclosure that I may try to duplicate
[18:52:05] <Duc> http://i1086.photobucket.com/albums/j459/Datsunworks/BP%20Splash/IMG_0017_zpsa8eaf645.jpg
[18:52:27] <enleth> one hell of a coolant pan
[18:52:35] <pfred1> it looks like a shower stall
[18:52:43] <pfred1> you should just get an old shower
[18:53:42] <Duc> really should buy a VMC LOL
[18:53:49] <pfred1> that's like a thousand bucks of plexi there at least
[18:54:43] <Duc> yea a old shower or even a new one from Home depot might be cheaper
[18:54:46] <enleth> corrugated polycarbonate roofing panels might be sufficient for the side walls
[18:54:57] <enleth> it's not entirely transparent but it's cheap
[18:55:52] <pfred1> find a sign company and get scraps off them
[18:56:21] <pfred1> that plastic they make signs out of they must have piles of it
[18:56:35] <pfred1> like when they take signs down
[18:57:00] <Duc> http://www.homedepot.com/p/Delta-35-7-8-in-x-35-7-8-in-x-71-7-8-in-Semi-Frameless-Neo-Angle-Shower-Enclosure-422061/203431139
[18:57:01] <Duc> lol
[18:57:30] <Duc> way to small thou
[18:57:34] <pfred1> yeah find one ripped out in a remodel
[18:59:01] <Duc> craigslist should be full of them
[18:59:28] <pfred1> I never find good deals on craigslist
[18:59:46] <pfred1> people there seem to be really interested in gettign as much money for stuff as possible
[19:00:14] <Duc> I low ball in person with fresh cash
[19:00:16] <Duc> it helps
[19:00:22] <pfred1> I bet
[19:00:40] <pfred1> I do a lot of yard sales and flea markets
[19:00:51] <pfred1> then people are priced to sell
[19:01:32] <pfred1> I got all of this for $10 http://i.imgur.com/s4hMwTG.jpg
[19:01:41] <Duc> or even ebay. Ive offered less than half a few times
[19:03:30] <pfred1> that dewalt drill even works
[19:04:03] <Duc> hell was accept for a offer of $1,000 for a 4th axis that was priced at 5k
[19:04:59] <pfred1> yeah finding people to come up with a grand is not always easy
[19:07:04] <Duc> I may keep a seperate saving account for machinery
[19:07:35] <pfred1> I don't spend a whole lot on it
[19:07:59] <pfred1> my big purchase this year was a set of dovetail cutters I only spent like $80 on those too
[19:08:27] <pfred1> I need to do more with those
[19:08:45] <pfred1> http://i.imgur.com/Yap1Lya.jpg
[19:09:21] <pfred1> I made my Z axis of my machine with them already though http://i.imgur.com/lSsNyBG.jpg
[19:09:59] <pfred1> that's homemade HDPE
[19:10:09] <Duc> I need to see where the wife's cat hide my new dovetail cutter
[19:10:23] <Duc> what are you planning on cutting with the machine?
[19:10:28] <pfred1> wood
[19:10:41] <pfred1> just decorative engraving
[19:10:59] <pfred1> I like to woodwork make little boxes but i decided my boxes are too plain
[19:11:17] <pfred1> so I figured a CNC would jazz them up
[19:12:52] <pfred1> it cuts through wood no sweat
[19:12:58] <pfred1> like its not even there
[19:13:52] <pfred1> I need smaller bits though
[19:14:30] <pfred1> that's some tooling I definitely need to buy
[19:15:20] <pfred1> I got some of them point engraving bits and I have some small end mills on order and i got the collet adapters
[19:15:34] <Duc> at least you got into the cheaper side of things
[19:16:03] <pfred1> yeah I'm not planning on milling AR receivers or anything like that
[19:16:19] <pfred1> but I might try CNCing my mill someday?
[19:16:40] <pfred1> I got one nema 34 motor for it already
[19:17:38] <pfred1> I still don't have a use for that sort of thing that i can think of
[19:22:08] <Duc> brb
[19:42:28] <enleth> pfred1: milk jug HDPE?
[19:42:53] <pfred1> yes
[19:43:01] <pfred1> blow molded plastic is the best
[19:43:14] <pfred1> it is slicker and harder
[19:54:24] <dioz> i was custom making a plenum for a residential furnace
[19:54:28] <dioz> and i slipped with the drill
[19:55:00] <dioz> and ended up catching my index finger knuckle on my right hand in a notched transverse connection
[19:55:08] <dioz> result was 14 stitches
[19:55:53] <dioz> http://imgur.com/sifmhWJ
[19:55:55] <dioz> there is the results
[19:55:56] <XXCoder> ow
[19:56:48] <dioz> when i was framing houses i seen 2 guys shoot themselves with spikers
[19:56:57] <dioz> i never understood how someone would manage to shoot themself with a spiker
[19:56:59] <dioz> then i figured it out
[19:57:32] <dioz> when you're framing a wall you hold the top plate and the studs with one hand and shoot with the other
[19:58:27] <dioz> the two people i witnessed fumbled ever so slightly with the gun to the p oint the safety was held by the top plate but the barrel was pointing passed the wood at their skin
[19:59:04] <dioz> they pull the trigger and the nail ever so slightly would graze the wood then proceed into their hand
[20:25:47] <pfred1> it is just about plastic melting season again over here
[20:43:43] <MacGalempsy> hello
[20:44:03] <XXCoder> yo
[20:44:24] <MacGalempsy> hows the weekend treated you?
[20:45:24] <XXCoder> pretty good
[20:45:32] <XXCoder> printed venus box and rotating rings
[20:45:44] <XXCoder> I dont think anyone can make rotating rings by anything but printer lol
[20:46:28] <MacGalempsy> nice, what kind of printer?
[20:46:46] <XXCoder> crap prusa i3 clone
[20:47:12] <MacGalempsy> pla?
[20:47:57] <XXCoder> yeah, though I have yet to try others
[20:50:19] <pfred1> I'm processing HDPE
[20:50:28] <pfred1> I got a new toaster oven this season
[20:50:34] <pfred1> convection
[20:50:48] <MacGalempsy> yesterday i wired the edm circuit. it required taking today off.
[20:52:25] <MacGalempsy> how does one process hdpe?
[20:52:34] <pfred1> with a knife and scissors
[20:52:50] <XXCoder> or build a grinder
[20:52:55] <pfred1> I have a whole routine i use for breaing bottles down
[20:52:57] <XXCoder> easy to do if you have mill
[20:53:00] <pfred1> breaking down even
[20:53:07] <XXCoder> its little more than tooth circle anyway
[20:53:16] <XXCoder> make bunch of those, assembly a grinder
[20:53:22] <pfred1> yeah I remelt my swarf
[20:54:02] <MacGalempsy> so you melt it and cast machinable stock?
[20:54:07] <pfred1> yes
[20:54:28] <pfred1> my stash http://i.imgur.com/MogRQ2i.jpg
[20:55:30] <pfred1> it is handy to have around the shop
[20:55:49] <pfred1> sometimes i use it as backing blocks when I'm drilling holes
[20:56:28] <MacGalempsy> cool. got a pic of the furnace?
[20:56:34] <pfred1> I made these spring loaded stablizer wheel deals for my CNC machien with it
[20:56:42] <pfred1> I just use a toaster oven
[20:57:04] <pfred1> here's the box i melt in http://i.imgur.com/RpqLjJq.jpg
[20:57:13] <pfred1> that's my new box
[20:58:00] <pfred1> I should take a pic of it full of molten plastic
[20:58:10] <pfred1> it looks cool it gets see through
[20:58:26] <pfred1> then it turns opaque again when it cools
[20:59:12] <MacGalempsy> so that box is the size of the finished piece?
[20:59:21] <pfred1> nah not really
[20:59:31] <pfred1> because it doesn't come out very square
[20:59:38] <pfred1> so I mill them swuare
[20:59:44] <pfred1> square even
[20:59:58] <pfred1> HDPE shrinks a ton when it cools
[21:00:13] <pfred1> that's what the diamond plate is for to clamp it
[21:00:15] <MacGalempsy> im trying to figure out the best way to make the stock for some aluminum mold bases
[21:01:01] <pfred1> here's my blast furnace for melting aluminum http://i.imgur.com/Ld6E4.jpg
[21:01:26] <pfred1> I found a couple of old scrap kilns and salvaged the fire bricks out of them
[21:02:06] <pfred1> then I stacked them all aroudn a metal bucket
[21:02:30] <MacGalempsy> nice. the videos on youtube look pretty straight forward.
[21:02:43] <pfred1> well I flipped that lawnmower over and filled it full of a grog mix too
[21:03:07] <pfred1> yeah melting aluminum is pretty wasy
[21:03:14] <pfred1> easy even
[21:03:17] <MacGalempsy> just got to empty the edm oil drum
[21:03:56] <MacGalempsy> the local recycler has aluminum for $1/lb
[21:04:07] <pfred1> if yo ucan get cast aluminum
[21:04:16] <pfred1> cast casts better than extruded does
[21:05:05] <pfred1> you got to be careful with castings though you don't want to try to melt magnesium
[21:05:20] <pfred1> burn a hole in your furnace if yo udo that
[21:06:13] <MacGalempsy> ok
[21:06:24] <MacGalempsy> i recall mg burns hot
[21:06:30] <pfred1> you can test castings before you nelt them
[21:06:30] <MacGalempsy> and green
[21:06:41] <pfred1> yeah it looks like ET is landing
[21:07:11] <pfred1> you clean a section then put some vinegar on it if it bubbles its mag
[21:08:31] <MacGalempsy> scatch a little off and light the powder
[21:09:43] <pfred1> al and fe is thermite
[21:09:51] <CaptHindsight> https://unpatent.co/learn
[21:10:10] <pfred1> not sure about al on its own
[21:10:11] <gregcnc> interesting
[21:11:10] <MacGalempsy> im sure there is a little more than al and fe
[21:11:28] <MacGalempsy> like what are the anion ligands?
[21:11:41] <XXCoder> I see you use mower as cart lol
[21:11:42] <XXCoder> nice idea
[21:11:58] <pfred1> XXCoder I saw it done online
[21:12:09] <XXCoder> you should checjk out myfordboy kiln
[21:12:11] <XXCoder> amazin
[21:12:13] <pfred1> yeah dead mowers are easy to come by
[21:15:03] <MacGalempsy> looks like thermites are al with an oxidizer. heat drives the initial rxn.
[21:15:39] <CaptHindsight> nanoparticle aluminum
[21:17:46] <pfred1> al and fe dust
[21:20:07] <MacGalempsy> particle size would effect the rxn rate
[21:22:03] <pfred1> that's why it works i think lots of surface area
[21:34:28] <pcw_home> Not Fe, Fe203 (rust)
[21:35:27] <pfred1> is there any other kind?
[21:35:37] <pcw_home> works with cupric oxide also
[21:35:55] <pcw_home> (if you want molten copper)
[21:36:25] <pcw_home> (or mercuric oxide) if you want mercury vapor
[21:37:07] <CaptHindsight> melts tall buildings in their tracks
[21:40:04] <XXCoder> MacGalempsy: you can turn wood powder into bomb
[21:40:11] <XXCoder> just fine powder and air at correct mix
[21:40:21] <XXCoder> one of wood factories blew up that way
[21:41:58] <pfred1> textile mills had the problem and grain silos too
[21:42:11] <dioz> what do you guys think of this welder
[21:42:14] <dioz> http://www.everlastwelders.ca/tigwelders/powertig-185-dv.php <-- ?
[21:42:20] <dioz> is this a decent welder for the price?
[21:42:24] <dioz> it ain't ab lue or a red
[21:42:34] <dioz> but it seems to be decent
[21:43:02] <dioz> how many amps should i be welding 26 gauge mild steel at?
[21:43:05] <dioz> 5amps?
[21:48:27] <XXCoder> no idea
[21:48:37] <XXCoder> maybe you know heh whats better HEPA filter?
[21:48:49] <dioz> huh?
[21:49:43] <dioz> there's a few things better than HEPA
[21:49:48] <dioz> but it depends what your goal is
[21:49:56] <XXCoder> filtering out mold and fine dust
[21:50:28] <pfred1> beats me mold and dust generally don't bother me
[21:51:08] <dioz> mold and fine dust are two different things
[21:51:22] <dioz> there's electrostatic air purification
[21:51:51] <dioz> ulpa
[21:51:55] <dioz> hepa
[21:55:22] <enleth> XXCoder: asbestos-rated filters will probably get most of that stuff
[21:55:46] <XXCoder> I just found out 3d printer dust is 100 nm lol
[21:56:06] <XXCoder> still need deal with mold anyway and dust
[21:56:30] <XXCoder> once I print abs I'll just pipe air oputside or something
[21:57:48] <enleth> and dealing with mold is probably better done by dehumidifying the room and applying anti-mold agents to walls, etc.
[21:58:11] <XXCoder> yeah I need landlord to do that
[21:58:34] <enleth> keeping it heated to keep the mold out might be a costly PITA though
[21:59:03] <XXCoder> if I owned house I would punch a hole in wall and add vent system in downstairs restroom/bath
[21:59:19] <XXCoder> it has no way to get rid of water besides opening window. I always bathe with open window.
[22:00:13] <enleth> well, maybe point it out to the landlord that if he doesn't pay for those fixes, the mold will eat his property sooner or later even though you're trying your best to prevent that in his very interest
[22:03:30] <MacGalempsy> we have a dehumidifier that runs all the time. output is essentially deionized water
[22:03:53] <MacGalempsy> dont drink it!
[22:03:56] <XXCoder> any good? https://www.amazon.com/Holmes-Tower-Allergen-Remover-HAP706-U/dp/B002QUZGV0
[22:04:00] <XXCoder> yummy
[22:04:03] <XXCoder> why?
[22:20:08] <MacGalempsy> one thing to consider is filter cost
[22:20:41] <MacGalempsy> that has always pushed me towards electrostatic
[22:20:59] <XXCoder> that one is $19 for 2
[22:21:11] <XXCoder> or one I guess https://www.amazon.com/dp/B005BFNI1W
[22:22:28] <CaptHindsight> where does it put the ions it takes out of the water?
[22:24:48] <XXCoder> into ion village where they can enjoy life without bothering humans
[22:58:12] <XXCoder> so MacGalempsy why dont drink deionized water lol
[23:17:29] <enleth> XXCoder: you probably won't be able to swallow it anyway
[23:17:44] <XXCoder> why?
[23:18:22] <enleth> it is so completely devoid of taste in such a strange way that most people have problem swallowing it, or have a gag reflex upon trying
[23:18:36] <XXCoder> interesing
[23:18:45] <enleth> at least for the pure distilled water
[23:19:02] <enleth> you really have to force it
[23:19:14] <enleth> and if you do, it's actually dangerous
[23:19:56] <XXCoder> whats side effects
[23:20:01] <enleth> it sucks ions out of your bloodstream and tissue by osmosis
[23:20:47] <enleth> so the effect is actually pretty similar to what happens when you're dehydrated - acute electrolyte imbalance
[23:20:54] <XXCoder> interesting. no worries though as I simply do not trust water made by machine not designed to make drinkable water lol
[23:22:21] <enleth> drinking a lot of high purity distilled water can actually kill you or put you in intensive care treatment
[23:23:15] <eeriegeek> nonsense
[23:23:36] <XXCoder> I see lots of crazy health sites say that
[23:23:39] <XXCoder> I dont trust those.
[23:23:48] <XXCoder> no scientific articles so far
[23:28:19] <XXCoder> wiki "The World Health Organization investigated the health effects of demineralized water in 1980, and its experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration. Magnesium, calcium, and other nutrients in water can help to protect against nutritional deficiency. Recommendations for magnesium have been put at a minimum of 10 mg/L with
[23:28:20] <XXCoder> 20–30 mg/L optimum; for calcium a 20 mg/L minimum and a 40–80 mg/L optimum, and a total water hardness (adding magnesium and calcium) of 2–4 mmol/L. At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed. For fluoride the concentration recommended for dental health is 0.5–1.0 mg/L, with a maximum guideline value of 1.5 mg/L to avoid dent
[23:28:20] <XXCoder> al fluorosis.[17]"
[23:28:47] <XXCoder> so long term there could be problems but besides that
[23:28:55] <enleth> eeriegeek: figurative "you", a healthy adult is probably going to be fine until the sheer amount of water ingested, distilled or not, starts to be dangerous
[23:29:18] <XXCoder> just take suppliment pills to cover missing elements
[23:29:22] <XXCoder> or just drink soylent heh
[23:30:51] <enleth> but trying to survive on distilled water without proper nutrition at hand, and/or being very young, elderly, ill from something else already, etc. is a bad idea
[23:31:39] <XXCoder> from research article "Demineralised water that has not been remineralized, or low-mineral content water – in the light of the absence or substantial lack of essential minerals in it – is not considered ideal drinking water, and therefore, its regular consumption may not be providing adequate levels of some beneficial nutrients."
[23:32:03] <XXCoder> so basically you will be fine, if lacking some essenatal stuff. hardly 911 call emergacy
