Back
[00:49:53] <miss0r> Goodmorning :) So yesterday evening I went and picked up my new drillpress. A swedish Strands s68l. I got it for free, if I came to pick it up myself. It seems everything is working excellent. and to my surprise, it has a X-Y table installed on there
[00:50:43] <miss0r> I have no idea how much it weighs in at, but I realy had to lay into it, to get it on and off the trailer, that much is for sure :)
[00:51:01] <SpeedEvil> :)
[00:52:11] <miss0r> So i'm thinking the first project for this one(after cleaning is complete) is milling a new table for it, as it has so many holes you would not believe it. and at some point in time someone tried to fill all the holes with epoxy, and did a realy crummy job.
[00:52:59] <miss0r> I wonder what this drillpress did in its former life.. perhaps it was in a school or something like that. Noone in their right mind would do this
[00:53:13] <enleth> miss0r: you might try drilling the crap out again and brazing the holes
[00:53:32] <enleth> with luck, it will not warp
[00:53:42] <miss0r> Hang on, i'll take a picture, to make my point :)
[00:54:22] <enleth> I've got several holes, including randomly positioned tapped ones, in my bridgeport's table
[00:54:59] <miss0r> yeah, wait till you see this. It must be the worst case i've ever seen
[00:55:12] <enleth> what kind of doofus drill *and* taps holes into the machine's table - I have no idea
[00:55:15] <enleth> *drills
[00:55:36] <miss0r> ^^ perhaps it was for some special mount of sorts
[00:55:50] <miss0r> Here we go: https://drive.google.com/open?id=0B51cA8Udo5i7ek1LYkVBd254b1k
[00:55:55] <miss0r> worst case i've ever seen
[00:56:42] <miss0r> tell me that is also the worst you've ever seen
[00:57:44] <enleth> what in the actual fucking fuck
[00:58:26] <miss0r> yeah. i'm happy about the x-y table. but it is pretty fucked. That is why i'll mill a new one :)
[00:59:50] <enleth> okay, this takes the cake - then shits on it and gobbles it whole
[01:00:02] <miss0r> I should post this pic to one of thoes 'there i fixed it' or 'crappy engineer' sites of some such
[01:00:27] <enleth> maybe the operator had parkinson's and was blind
[01:00:43] <miss0r> combine that with just not caring, and I think we have a winner
[01:01:02] <miss0r> Or someone told him the table top was $10 each, and acted like a wasteplate
[01:01:56] <miss0r> and the epoxy came after the realization that $10 wouldn't even cover the shipping
[01:02:46] <enleth> I'd say mill the whole thing off down to the bottom of coolant channels, then bolt a new top onto that
[01:02:59] <enleth> maybe even a prefab t-slotted aluminum slab?
[01:03:25] <enleth> although it might warp after you mill so much off of it, cast iron does that sometimes
[01:04:35] <miss0r> Thats actualy not a half bad idea. I have a peice of 1 1/4 inch steel plate. I was thinking of milling t-slots and coolant channels in that - and then do as you say, and mill the table down and bolt it on
[01:05:13] <enleth> except there's no way to tell if it's going to warp or not before milling
[01:05:28] <enleth> and it can take a little time to do that
[01:05:28] <miss0r> Yeah, i'll have to take that chance...
[01:05:36] <miss0r> well.. another plan:
[01:06:37] <miss0r> When looking closely at the table, I can see(through all the crud) that the side of the table where the handwheel is mounted, the coolant channel is not very deep, as the leadscrew is under there. So, perhaps I will just add a plate on top of the table, and bolt it down to it.
[01:06:47] <enleth> I'm no expert on heavy milling in cast iron but what I've read suggests to do the cut, see if there's any warping immediately aterwards, then wait a week or so to see if it changed
[01:06:50] <miss0r> Perhaps just taking a skimpass, to make it nice and level
[01:06:58] <enleth> that would work too
[01:07:25] <miss0r> The support arm for the table looks nice and fat, I don't think it would mind the added weight
[01:07:47] <enleth> you might stop somewhere halfway in too
[01:08:03] <enleth> take off the worst part of the top layer
[01:08:20] <miss0r> yeah, I'll probally not remove more than 4-5mm at the most
[01:08:54] <enleth> and braze in the holes at the edges for cosmetic effect
[01:09:04] <miss0r> with 1 1/4" plate, it just have to sit a few places for this to work
[01:13:19] <miss0r> To make room for this drillpress I will have to do the following: Move some drawers from one wall to a new wall(A windows I just sealed off), Cut and install shelfs on the wall I just removed the drawers from. Take what is in a bookcase, and move it to the new shelfs. Tear down bookcase, and move a closet to that location, so the drillpress can be installed where the closet was... let the tetris begin
[01:18:47] <enleth> miss0r: https://www.youtube.com/watch?v=HS5M1gm0KH0
[01:19:21] <miss0r> b...but... it's only 10 hours :/
[01:27:43] <SpeedEvil> Or remove the epoxy, tidy it up, fill it with braze, do a skim cut, and call it art.
[02:37:45] <Deejay> moin
[02:38:07] <XXCoder> SpeedEvil: throw it on wall, few splashes of paint. done.
[02:39:03] <archivist> miss0r, time to extend your shed
[02:39:22] <XXCoder> why? cheaper invent time lord inside is bigger tech
[03:11:34] * SpeedEvil wants a matrix-esque machine tool library
[03:11:48] <XXCoder> that'd rock
[03:12:06] <SpeedEvil> Like the gun one.
[03:12:40] <XXCoder> and tech in conod's time machine - they invented something that creates flaw in spacetime that can cut anything in any direction
[03:12:55] <XXCoder> they realize they can use in place of drill and endmills so on
[03:13:14] <XXCoder> and since there is no sideforce at all they can use rapids to cut parts lol
[04:16:28] <Jymmm> Pfff, you guys and your fancy coolant pumps been doing it all wrong... https://www.youtube.com/watch?v=5dSnOFhTWHo
[04:16:56] <XXCoder> NDA channel lol
[04:17:01] <XXCoder> nondisclosure agreement channel
[04:21:32] <XXCoder> Jymmm: why did he use lighter on exposed wires?
[04:22:15] <Jymmm> XXCoder: to "expand" the PVC. he's using them as one-way check valves.
[04:22:22] <XXCoder> ahh
[04:22:38] <Jymmm> the little wires would be the "flapper" as it were.
[04:25:13] <XXCoder> that is interesting
[04:25:30] <XXCoder> honestly I would go and grab $5 fountain water pump lol
[04:25:30] <Jymmm> which part?
[04:25:41] <XXCoder> pump creation
[04:26:09] <Jymmm> you mean overall? what HE did? or the check valve thing?
[04:26:11] <XXCoder> one difference is it seems to sputter which may be wanted in certain uses
[04:26:15] <XXCoder> overall
[04:27:16] <Jymmm> XXCoder: Here ya go, you can make your own http://www.ebay.com/itm/1-4-Quick-Connect-Check-Valve-for-RO-Pure-Water-Reverse-Osmosis-System/252509083894
[04:29:22] <XXCoder> heh larger I guess
[04:30:13] <Jymmm> 1/4" standard PE tubing, usually used for frig ice maker
[04:32:18] <Jymmm> XXCoder: Then get yourself some of these http://www.ebay.com/itm/5-Pack-60cc-2oz-CATHETER-TIP-Easy-Glide-SYRINGES-60mL-NEW-SYRINGE-ONLY-NO-NEEDLE-/271551040760
[04:36:06] <Jymmm> XXCoder: or this https://www.youtube.com/watch?v=Y06mzBdgs1M
[04:36:40] <Jymmm> XXCoder: This is the EXACT same thing as that other pump https://www.youtube.com/watch?v=vaho7JSVS1I
[04:42:52] <Jymmm> XXCoder: DIY check-valve https://www.youtube.com/watch?v=DG6own141z0
[04:56:01] <XXCoder> the ovc one looks very effective.
[04:56:16] <Jymmm> =)
[05:00:09] <XXCoder> check valve very simole lol
[05:06:09] <XXCoder> Jy its amazing that price goes up very quickly lol. http://www.usplastic.com/catalog/item.aspx?itemid=23375
[05:06:14] <XXCoder> was curious in pricing
[05:14:09] <Jymmm> XXCoder: steel/chrom is about the same or cheaper
[05:14:31] <XXCoder> well depends on use. ayric is great for water and air
[05:14:50] <XXCoder> wouldnt steel evenually rust?
[05:15:33] <Jymmm> yeah, but there are brass balls too
[05:15:46] <Jymmm> acrylic can easily chip too
[05:16:04] <XXCoder> so you got brass balls ;)
[05:16:11] <Jymmm> well, not THAT easily but it can
[05:16:20] <Jymmm> damn skippy I do!
[05:17:24] <XXCoder> lol
[05:22:43] <Jymmm> Interessting... a 4" pipe holds 0.653 gallons per foot. but a 5" holds 1.02 gallons per foot.
[05:22:50] <jthornton> morning
[05:22:57] <XXCoder> hey the super jt
[05:23:02] <Jymmm> jthornton: howdy
[05:23:18] <jthornton> what's happening
[05:23:37] <Jymmm> jthornton: SSDD
[05:23:39] <XXCoder> jt I was trying to print caps for 608 bearing but failing, its tiny and heat creep is BIG problem
[05:23:49] <XXCoder> so I put up my big room fan to blow on it
[05:23:57] <XXCoder> seem to be successful.
[05:24:17] <jthornton> need to add some print fans lol
[05:24:31] <XXCoder> oh really? didn't know? heh ;)
[05:24:56] <XXCoder> maybe I can buy a box fan and build it into framework, blow down ;)
[05:25:02] <XXCoder> kidding. hows your printing
[05:25:19] <Jymmm> XXCoder: LN2 baby!!!
[05:25:28] <XXCoder> ln2?
[05:25:46] <jthornton> still trying to get linux mint 18 64bit up and going last thing is pronterface
[05:25:56] <Jymmm> XXCoder: Liquid Nitrogen... −320 °F
[05:26:22] <XXCoder> heh that'd be super efgective. one drop a few seconds or something,.. till glass shatters lol
[05:27:14] <Jymmm> XXCoder: oh it's fun stuff, especially when you just had the 5000 gallon tank filed that morning and there is a valve stuck open in the afternoon
[05:27:40] <XXCoder> ow nitrogen is very breathable but if you replace all air with it...
[05:27:53] <XXCoder> it would feel normal if warmed up but you sure aren't getting any oxy
[05:28:52] <Jymmm> This is LIQUID nitrogen, flooded the entire lab, the hallway, and into an adjacent area with inch of the stuff
[05:29:29] <Jymmm> you just on desks and shit =)
[05:29:34] <Jymmm> jump*
[05:30:17] <XXCoder> crazy
[05:30:26] <XXCoder> jump up or get uber frostbites
[05:31:00] <Jymmm> more like foot cracks and falls off
[05:31:17] <XXCoder> well yeah frostbite is just start of it LOL
[05:31:20] <Jymmm> but hey, you have two
[05:31:40] <XXCoder> heh my feet is far less costly loss than my hands.'
[05:31:50] <XXCoder> I do stuff and talk with my hands.
[05:33:57] * Jymmm crazy glues XXCoder hands to his butt... Now you are talking out of your ass (again? still?) =)
[05:34:22] * XXCoder sends eaf assassins
[05:34:27] <XXCoder> *deaf
[05:34:36] <Jymmm> lol
[05:34:48] <XXCoder> probably noisy assassins :P
[05:35:24] <Jymmm> Damnit, whats the volume of water that can pass thru 1/4" being gravity fed?
[05:35:52] <XXCoder> heh used to can do calculus to figure that
[05:36:17] <Jymmm> I keep finding "...at x psi"
[05:36:18] <XXCoder> but basically integation from 0 to (t) of circle area
[05:36:42] <XXCoder> the flow rate is 9.86 m/s^2
[05:36:47] <XXCoder> thats g after all
[05:37:36] <Jymmm> eh, I'll just do it old school with a stopwatch
[05:37:44] <XXCoder> why
[05:38:05] <Jymmm> math is hard?
[05:38:44] <XXCoder> differial would do better job I guess but never went there.
[05:51:38] <Frank_10> cant u change the gravity pressure to psi?
[05:52:19] <XXCoder> yeah
[05:52:31] <XXCoder> you need one additional info
[05:52:35] <XXCoder> height of water tank
[05:52:46] <TurBoss> hello!
[05:52:51] <archivist> it varies as it empties
[05:52:57] <XXCoder> and it changes, hence nesscary usage of differial calculus
[05:53:08] <XXCoder> though you can do rough guess
[05:56:25] <XXCoder> jthornton: made that X belt torsoner yet?
[05:56:36] <Frank_10> yeah true; but it will keep constsntly changing how do you know how long you should take the height
[05:57:01] <jthornton> still trying to get mint 18 64 bit up and running
[05:57:01] <XXCoder> Frank_10: basically close guess is just stopping each minute
[05:57:09] <XXCoder> and adjust calculations
[05:57:18] <jthornton> well spent yesterday splitting firewood
[05:57:40] <XXCoder> you burn wood for heat eh
[05:58:02] <Frank_10> i want to buy an axe
[05:58:10] <jthornton> in the garage, shop and new shop yea
[05:58:21] <jthornton> get an X27
[05:58:28] <Frank_10> i dont need any fire wood; but still; they seem fun lol
[06:09:36] <Frank_10> bad news for jt, internet down hehe
[06:10:51] <XXCoder> apparently heh
[06:53:14] <XXCoder> Jymmm: https://www.youtube.com/watch?v=FmxE3fFBWS0
[06:53:32] <XXCoder> uh lemme get better video
[06:53:55] <XXCoder> ah https://www.youtube.com/watch?v=6WR5JfsjOsU
[06:54:15] <XXCoder> riding a laptop :P
[07:21:41] <Frank_10> guuys; maybe i've found my issue with not recognizing the 5i25; in bios i've found pci express configuration while my pc is only pci legacy slot available; is that normal? btw i cant find any pci option
[07:31:58] <Frank_10> wiiiiii now it recognizes my 5i25
[07:32:24] <Frank_10> stupid me trying to do stuff in bios without knowing shit
[07:32:55] <archivist> makes you learn stuff!
[07:33:16] <Frank_10> and bother people on the chat hehehe
[07:33:37] <archivist> then we have to learn it to help you
[07:35:42] <Frank_10> heh
[07:37:34] <Frank_10> this irc app for android is awesome low bat consuption
[07:50:43] <nubcake> hey
[07:51:27] <XXCoder> hey
[07:51:31] <XXCoder> Frank_10: andchat?
[07:56:10] <Frank_10> yep
[07:56:18] <Frank_10> dont hack me please
[07:56:20] <Frank_10> lol
[07:58:49] <XXCoder> should have asked earlier
[07:59:01] <XXCoder> already ordered bunch dilios to deliver to your house. sorry
[08:06:13] <Frank_10> they will have a loong flight
[08:06:15] <Frank_10> heh
[08:06:34] <XXCoder> lol
[08:43:15] <JT-Shop> I think I'll give up on Linux Mint 18, nothing works on it
[08:55:06] <FloppyDisk525> I don't think you're allowed to give up on mint. Some linux principal says so.
[08:55:39] <FloppyDisk525> But, on that note, that's frustrating and sorry to hear it's not working.
[08:56:50] <FloppyDisk525> at one point, you were very high on it vs. the deb. Seems like ubuntu has made inroads back in. I installed Xubuntu on a machine for something else and thought it ok.
[08:57:00] <FloppyDisk525> But, I'm not overally picky on that stuff...
[08:57:25] <FloppyDisk525> Only cuz I don't know any better. Which isn't good, either.
[09:04:18] <jthornton> I use mint but 18 is a pia because stuff I want like ponterface don't work on 18 yet
[09:04:32] <jthornton> so I'll back down one level
[09:04:57] <jthornton> I only tried 18 cause cura 2 only works on 64bit systems...
[09:05:05] <jthornton> update hell all over again
[09:13:06] <FloppyDisk525> No doubt.
[10:56:06] <Tom_L> jthornton, you should keep a drive aside for playing with stuff like that
[11:31:57] <enleth> jesus, how bad someone must have screwed up for a phrase like "$WHATEVER_OSS_SOFTWARE doesn't work on $VERSION of $DISTRO" to be true
[11:32:10] <enleth> this literally should never be a thing
[11:33:19] <enleth> save for, maybe, completely unmaintained software after very major non-backwards compatible changes in very important libraries, which are announced years in advance
[11:34:07] <enleth> what does it even mean that it "doesn't work on", what is there to not work in an open source program on an open source OS?
[11:40:28] <archivist> you must have missed out of a bit of real upgrade hell
[11:42:44] <Tom_L> enleth ask microsoft
[11:48:29] <Frank_10> im in a bit of a situation; heres the thing; in the build of my cnc router(gantry 120kg) i've decided to use 2servos to move the gantry axis; but im in a bit of a crunch; as im running out of $$ for spending in the machine and i thought that i could do some direct drive for a while; to save some money (400usd); i will be running with 2x750w panasonic servos; is it posible?? any no no detail that im missing besides not using the servos max power cuz of
[11:50:30] <Tom_L> line length exceeded
[11:58:49] <Frank_10> sure? i ended at ty;( thank you)
[11:59:20] <Tom_L> max power cuz of
[11:59:58] <Frank_10> lol; i see the hole text, weird
[12:00:11] <Frank_10> because of the reduction. end
[12:00:30] <archivist> there is a max n characters in IRC lines
[12:01:12] <archivist> better IRC clients notice and split for you
[12:01:16] <IchGucksLive> hi
[12:01:18] <Frank_10> 🍉
[12:01:43] <Frank_10> hey
[12:04:00] <IchGucksLive> hi nubcake weather here today amazing
[12:04:15] <IchGucksLive> Frank_10: hoew is the setup
[12:06:01] <Frank_10> excuse me? what is it that your talking about? you read my recent text?
[12:07:26] <IchGucksLive> oh servo mashine
[12:07:37] <IchGucksLive> gantry that is a hard start
[12:07:48] <IchGucksLive> money
[12:08:08] <IchGucksLive> i use 8Nm steppers on 30:1
[12:08:16] <IchGucksLive> that moves nearly 1tonn
[12:08:26] <IchGucksLive> at 72V
[12:08:53] <IchGucksLive> max is near 20m/min at 0.01
[12:08:59] <IchGucksLive> mm ofcause
[12:13:00] <Frank_10> lol thats big; what are you moving
[12:13:30] <Frank_10> its hard to believe thar you can do 20m/min with that load
[12:13:50] <IchGucksLive> there is no high acceleration
[12:14:08] <IchGucksLive> needs more then 10inches toi full speed
[12:14:11] <enleth> archivist: well, maybe it's years of using slackware, *BSDs and gentoo while avoiding any *buntus
[12:16:02] <Frank_10> still its hard to know for sure how my gantry would do;
[12:17:02] <IchGucksLive> it will brig you to heaven
[12:24:00] <IchGucksLive> hi ayjay_t
[12:40:14] <terkaa> hi
[12:41:26] <JT-Mobile> hi
[12:44:23] <IchGucksLive> hi
[12:45:28] <Frank_10> hi
[12:47:29] <terkaa> Anyone intrested in helping me with spindle speed oscillating
[12:47:31] <terkaa> ?
[12:49:13] <archivist> terkaa, perhaps ask a better question
[12:49:18] <JT-Mobile> just ask your question
[12:50:18] <terkaa> https://www.youtube.com/watch?v=Rcnlw9ZD9YA
[12:50:40] <terkaa> that starts when external override switch is used
[12:51:03] <terkaa> everything is fine if gmoccapy SOVR slide is used
[12:51:56] <archivist> use halscope to narrow it down
[12:51:56] <terkaa> It is open loop spindle
[12:52:31] <terkaa> how exactly?
[12:53:23] <archivist> we dont know if this is a hardware or software problem, data in or data out or what
[12:53:55] <archivist> halscope can look at signals
[12:58:24] <terkaa> I have checked override counts and that does not oscillate
[12:58:42] <terkaa> which signals would be good to check?
[12:59:23] <archivist> speed, and the signals that read back the spindle speed
[12:59:54] <terkaa> but there is no read back since this is open loop
[13:00:25] <archivist> you can be reading the speed even with open loop
[13:00:45] <archivist> are we supposed to guess your system
[13:02:19] <terkaa> There is nothing connected to spindle.-speed-in
[13:03:00] <archivist> so the display is pure random ?
[13:03:30] <terkaa> that display shows commanded speed * override
[13:03:34] <terkaa> not actual
[13:05:30] <IchGucksLive> hi
[13:07:38] <nubcake> hi
[13:08:00] <Jymmm> XXCoder: Shit, I have some of those rear casters and an old 386 laptop soemwhere
[13:08:03] <nubcake> unser wetter war nicht so cool, unter der woche soll's aber 15° kiregen :)
[13:14:36] <terkaa> Here is a thread on linuxcnc.org : https://forum.linuxcnc.org/49-basic-configuration/31706-spindle-override-with-wsum-switch-bouncing
[13:14:53] <terkaa> I cannot figure this out
[13:25:33] <mikeh_> anyone know off the top of their head which colour of Rizla's are 1 thou? just bought a pack of Blue's based on a random forum post that said blues were 1 thou but the micrometer says it's 0.5 thou
[13:26:46] <archivist> I doubt they are calibrated :)
[13:27:51] <mikeh_> oh for sure
[13:33:25] <terkaa> ?
[13:36:18] <IchGucksLive> Gn8
[13:43:17] <miss0r> 'New' drillpress installed. horay! that was alot of hard work. Now to make it function like it should, after years'n years of abuse
[13:44:03] <renesis> mikeh_: almost all rice papers are like 0.001 +- 0.0005
[13:44:38] <renesis> really everything ive measured, usually smoking brand and elements
[13:58:34] <pfred1> hey pcw_home or pcw_mesa are you around?
[14:00:37] <mikeh_> renesis: great, thanks. I guess i picked the one brand that was thinner :P
[14:00:53] <mikeh_> i guess it doesn't matter, 0.5 is just as easy to type as 1 :P
[14:01:10] <pfred1> 0.5 is a nice round number
[14:01:23] <pfred1> it's 1/2
[14:03:27] <pfred1> or one half
[14:04:18] <renesis> mikeh_: i found them to be pretty consistent between brands and batches
[14:05:12] <renesis> im eyeballing it on a .001" dial caliper, but they tend to be within a needle width of .001"
[14:06:12] <pfred1> I picked up some real Mitutoyo Absolute Digimatic calipers
[14:06:15] <renesis> yeah elements are definitely on the low side
[14:06:19] <renesis> neat
[14:06:30] <pfred1> but they're really old ones
[14:06:51] <pink_vampire> hello everyone
[14:06:57] <pfred1> hi vamp
[14:07:22] <pink_vampire> how are you
[14:07:24] <pfred1> I think once i may have seen these drift but ti could have been some dust in them too
[14:07:30] <mikeh_> i was thinking of getting a digimatics
[14:07:37] <pfred1> they're nice
[14:07:38] <mikeh_> i have a $130 credit to blow on something :P
[14:07:53] <pfred1> that's about what they cost new
[14:08:07] <pfred1> I got these for $10
[14:08:16] <pfred1> but with a dead battery
[14:08:45] <pfred1> I could have spent a fortune in that guy's shed that day
[14:08:46] <mikeh_> https://i.imgur.com/VWV1sKu.jpg
[14:09:13] <pfred1> I have mikes but I don't really use them
[14:09:44] <pfred1> I have sime Polis imported mikes they work
[14:09:49] <pfred1> polish even
[14:10:18] <renesis> oh damn thats like, wood paper
[14:10:51] <pfred1> you want Club papers they are as light as a butterfly's wing, and leave no ash when burned
[14:11:13] <pfred1> though they were being counterfeited a few years back
[14:11:23] <pfred1> I could tell because they were leaving ash when burned
[14:11:41] <mikeh_> i don't want to actually smoke them :P
[14:11:42] <renesis> they maybe just changed them
[14:11:55] <pfred1> why would you change a great thing?
[14:12:09] <renesis> mikeh_: elements look about the same, i think its smoking brand red thats .001
[14:12:48] <mikeh_> i might go to the shop and buy one of each
[14:13:00] <renesis> https://www.amazon.com/Bundle-Items-Smoking-Rolling-Sampler/dp/B00JLO0JO8
[14:13:11] <renesis> its either red or black
[14:13:21] <pfred1> for shim stock you want some of the thin foils
[14:14:31] <renesis> pfred1: money
[14:14:46] <renesis> you start the brand with quality to build credibility
[14:14:54] <mikeh_> due to some youthful indiscretions i know that convince stores around here probably only sell rizla blue and silvers as well as zig zag white's
[14:15:06] <renesis> then you get old, so you drive down quality for higher margins and hope your cred lasts longer than your life
[14:15:09] <renesis> or something
[14:15:12] <mikeh_> lol
[14:15:49] <mikeh_> actually i lie, because i'm sure one of the bong shops in town would have a wide selection :P
[14:15:50] <pfred1> renesis maybe
[14:16:32] <renesis> mikeh_: as is their business to
[14:16:34] <pfred1> the fakes did look just like the real thing the only way I coudl tell was by torching sheets
[14:17:06] <renesis> omg usgp is right now
[14:17:19] <pfred1> we used to burn them just for the kick of watching them disappear
[14:17:26] <mikeh_> i wish i had cable
[14:17:33] <renesis> OMG TURN ON YOUR TORRENT BASED FIA RESISTANT F1 STREAMS RINAOW
[14:17:38] <mikeh_> i'm not even sure if they'd show motogp on tv in canada
[14:17:43] <renesis> mikeh_: download acestream
[14:17:43] <mikeh_> oh
[14:17:48] <mikeh_> f1?
[14:17:49] <pfred1> where is the race?
[14:17:49] <mikeh_> bah :P
[14:17:58] <renesis> cota, austin
[14:18:01] <pfred1> I used to go watch the GP in Unadilla
[14:18:15] <renesis> go to reddit, click on race thread, look for hennogarvies streams
[14:18:30] <renesis> yay henno
[14:18:46] <renesis> and ya im not paying for cable just for F1, bernie sold it theyre going to do net streams next year most likely, i will pay
[14:18:58] <pfred1> ah F1
[14:19:01] <renesis> i cannot afford, i will still pay for entire weekends
[14:19:15] <renesis> yes its still drama
[14:19:18] <pfred1> my Dad knew Rodger Penske
[14:19:58] <pfred1> he still races Formula doesn't he?
[14:20:37] <pfred1> roger came from bernardsville?
[14:20:39] <Roguish> GM really F***d up when they closed Saturn instead of selling it to Penske.
[14:20:55] <pfred1> he owned a car dealiership
[14:21:21] <Roguish> guess they didn't want the competition. Penke would have been really good for Saturn.
[14:21:32] <pfred1> my dad's best friend was this guy https://en.wikipedia.org/wiki/Mark_Donohue
[14:21:51] <pfred1> so that's how he knew Roger
[14:22:04] <pfred1> but when Mark passed away that was that
[14:22:31] <pfred1> although my Mom has been at a picnic with mario Andretti
[14:22:56] <pfred1> he was big in Formula racing
[14:23:39] <pfred1> she's got some stories
[14:23:49] <pfred1> all the drivers liked her
[14:24:49] <pfred1> probably because back in the day she was ah pretty hot
[14:24:56] <pfred1> heh
[15:00:03] <terkaa> I am back
[15:12:14] <Jymmm> terkaa: A lil warnng next time... eeeeeesh ?! ;)
[15:18:58] <terkaa> ?
[15:21:58] <terkaa> I will try to be more --verbose
[15:22:12] <terkaa> :)
[15:25:40] <terkaa> It is Gn soon. It will be monday morning within next 8 hours
[15:32:20] <terkaa> Gn
[15:59:57] <MarkusBec> hm buildbot does not contain hostmot2 for jessie ?
[16:00:40] <MarkusBec> or what is the trink to get hostmot working
[16:06:46] <andypugh> What fun! Doing bitmasking in G-code in decimal-coded binary.
[16:07:12] <andypugh> (And no, I don’t mean binary-coded decimal :-)
[16:11:29] <Frank_10> only if i could understand what your saying... sigh for beeing new around heh
[16:11:49] <nubcake> Frank_10: same here ^^
[16:13:38] <hetii> Hi :)
[16:13:39] <nubcake> night everyone
[16:14:21] <hetii> Q: Is motor driver is set for eg in half step mode is it mean that I also need to set that mode for software in PC or grbl in my case ?
[16:19:32] <gorbypark> hmmm :(
[16:19:51] <gorbypark> i somehow have 0.022 backlash in my y axis, while only 0.002 in my x
[16:20:44] <MarkusBec> pcw_home: pcw_mesa any idea
[16:21:20] <MarkusBec> i try to get the preempt kernel working on jessie kernel works fine
[16:21:46] <MarkusBec> but there is no hostmod available in the buildbot
[16:22:09] <MarkusBec> hostmot
[16:29:10] <pfred1> gorbypark backlash is one thing I have thankfully avoided so far
[16:38:38] <zhivko> Hello My friends
[16:39:05] <zhivko> I was able to write udp server component if somebody is interested: https://github.com/zhivko/machinekit/blob/master/mycomponents/udp.icomp
[16:39:14] <zhivko> but now... i have question..
[16:39:55] <zhivko> I think I once read in documentation of linuxcnc there is some setting - that allows one to configure linuxcnc in a way that when it is started it doesn't need homing...
[16:39:55] <zhivko> But I forgot setting - and cannot find it now - maybe somebody knows ?
[16:41:02] <JT-Shop> got love it when people on #reprap answer your question with bs and then say they never used xyz lol
[16:42:53] <pfred1> JT-Shop what's xyz? I never used it
[16:44:24] <JT-Shop> what ever you want it to be...
[16:44:50] <pfred1> ah, I see
[16:45:33] <pfred1> I need to adjust this board again
[16:45:45] <pfred1> I'm never going to get this circuit built
[16:50:44] <andypugh> hetii: Yes, but no. You need the scale to be correct, so that the correct number of pulses are sent per engineering unit. That sort-of encodes the microstep ratio, but isn’t explicitly a microstep setting.
[16:51:18] <andypugh> zhivko: You need the setting [TRAJ]NO_FORCE_HOMING
[16:52:16] <andypugh> zhivko: http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_traj_section
[16:53:31] <Deejay> gn8
[16:53:34] <Nick-Shop> NO_FORCE_HOMING = 1 works
[16:54:01] <pfred1> use the force Luke!
[16:54:22] <pfred1> or in this case Homie?
[16:54:35] <andypugh> MarkusBec: You need to install the separate LinuxCNC_firmware package. Or you can get the firmwares in a ZIP file from the Mesa site.
[16:57:50] <andypugh> MarkusBec: Open the Synaptic Package manager and search for “hostmot2”
[16:58:01] <pfred1> apt-cache search
[16:58:40] <pfred1> apt-cache search hostmot2
[16:59:19] <pfred1> I ain't run Synaptic in years now
[16:59:45] <pfred1> although I have to admit I used it a few times when it first came out
[17:00:32] <pfred1> but if you know apt-cache search, and aptitude show, then Synaptic is less than useful
[17:16:48] <andypugh> Does anyone know of a free, good, 5-axis G-code simulator?
[17:17:31] <pfred1> I'm lucky I found a good 2.5D simulator
[17:23:32] <skunkworks_> andypugh, what are you making?
[17:23:38] <XXCoder> Jymmm: lol
[17:24:03] <XXCoder> pfred1: of what type
[17:24:13] <Jymmm> XXCoder: ?
[17:24:55] <Jymmm> andypugh: linuxcnc sim ?
[17:25:01] <pfred1> XXCoder a G-code simulator
[17:25:05] <XXCoder> ahh
[17:25:20] <XXCoder> Jymmm: your comment about your old laptop and casters
[17:25:26] <andypugh> I am running a sim but it’s hard to see if its doing the right thing.
[17:25:28] <Jymmm> XXCoder: ah, =)
[17:27:41] <zhivko> @nick-shop: Thank you man!
[17:28:49] <zhivko> in what section I need to put: NO_FORCE_HOMING
[17:29:42] <zhivko> TRAJ
[17:29:44] <zhivko> OK...
[17:29:47] <zhivko> found in docs...
[17:44:47] <MacGalempsy> CaptHindsight: I think I got the final recipe for the foundry cement figured out. https://flic.kr/p/NvcAVH
[17:45:59] <MacGalempsy> going to mix up a tester of it and we'll see how it works out
[17:46:14] <XXCoder> yummy
[17:48:07] <pfred1> I found two scrap kilns and I pulled all of the bricks out of them
[17:48:25] <SpeedEvil> yay
[17:49:31] <pfred1> SpeedEvil that's what you say until you see the furnace I built out of them http://i.imgur.com/Ld6E4.jpg
[17:50:01] <pfred1> but it was cheap, and easy, and who don't like it like that?
[17:50:01] <SpeedEvil> Does it work?
[17:50:05] <XXCoder> pfred1: nice
[17:50:08] <pfred1> yeah I melted aluminum in it
[17:50:14] <SpeedEvil> :)
[17:50:24] <pfred1> but you can probably melt aluminum on a barbeque too
[17:50:41] <XXCoder> pfred1: your wires lash up look like bad mspaint drawing of it. lol
[17:50:43] <pfred1> it ain't exactly hard to do
[17:51:02] <pfred1> I see what you mean yes
[17:52:06] <pfred1> I have to get back into melting aluminum it is kind of fun to do
[17:52:52] <pfred1> but now I'm more into melting HDPE it is even easier and I find it handier
[17:53:23] <XXCoder> nice
[17:53:36] <pfred1> you ever see my Z axis I made out of some of my HDPE?
[17:53:56] <MarkusBec> andypugh: pfred1 no hostmot2-firmware for jessie but i managed it by downloading the drivers from the mesa side
[17:54:28] <pfred1> MarkusBec you might have to add a repository?
[17:54:36] <pfred1> which don't sound pleasant
[17:54:53] <MarkusBec> i have a new pc for my old mil with a mesa 7i43
[17:54:54] <pfred1> did you run aptitude update?
[17:55:08] <pfred1> sometimes it finds you new junk
[17:55:10] <MarkusBec> the old PC is dead becouse of a HW fail
[17:55:20] <MarkusBec> pfred1: yes
[17:55:23] <pfred1> k
[17:55:32] <MarkusBec> now i have a new problem
[17:55:40] <MarkusBec> the 7i43 is epp based
[17:55:54] <MarkusBec> but the new pc had no parport
[17:56:01] <MarkusBec> i added a pcie card
[17:56:06] <pfred1> boards are cheap
[17:56:08] <pfred1> ah you have one good
[17:56:17] <MarkusBec> but it seamse like ther are no pci cards with epp suport...
[17:56:21] <pfred1> lspci -v
[17:56:59] <andypugh> MarkusBec: Which motherboard?
[17:57:29] <pfred1> I wonder if my controller runs ssh?
[17:57:42] <pfred1> I wonder what's it's IP is?
[17:57:46] <MarkusBec> dell optiplex 7010
[17:57:48] <andypugh> (I am fairly sure that lots of folk run Pico and Mesa boards through PCI cards)
[17:58:14] <MarkusBec> ah pci is not the problem
[17:58:37] <MarkusBec> the problem is i have a old 7i43 mesa card with epp parport
[17:58:41] <pfred1> board is in the system and you ran lspci -v ?
[17:59:34] <MarkusBec> Serial controller: Device 1c00:3250
[17:59:42] <pfred1> that ain't it
[17:59:52] <MarkusBec> io port is 0xe100
[18:00:11] <MarkusBec> no irc at the cnc pc at the moment
[18:00:23] <pfred1> how about dmesg | grep -i parport
[18:00:58] <pfred1> hmm that ain't gonna work nothing came up here for that

[18:02:53] <MarkusBec> this outbut is definitly the card
[18:03:04] <MarkusBec> if i removed it after shutdown
[18:03:18] <andypugh> markusbec_cnc: All Pico cards need an EPP Parport, and I have seen Jon discussng which PCI cards work.
[18:03:52] <MarkusBec> i think this card is just crap
[18:04:02] <MarkusBec> it was the cheapest from amazon
[18:04:07] <MarkusBec> i can get next day
[18:04:09] <andypugh> Not impossible. Which one is it?
[18:04:14] <jdh> I have a pci pport with 7i43

[18:05:37] <jdh> oh, pci-e
[18:05:52] <pfred1> does that matter?
[18:06:00] <andypugh> Shouldn\t
[18:06:06] <pfred1> I wouldn't think it would
[18:06:25] <pfred1> as long as it plugs in it should work
[18:06:34] <jdh> it matters in that my card taht works fine with 7i43 won't fit in that slot
[18:06:40] <MacGalempsy> that is gorgeous. what all do you make with it?
[18:06:49] <pfred1> yeah that's the as long as it plugs in deal
[18:07:43] <pfred1> that card does look a little cheesy but it should work
[18:08:19] <jdh> I had another one what would not work.
[18:08:42] <MarkusBec> epp is not supported by all pci cards
[18:08:47] <MarkusBec> better
[18:08:48] <pfred1> it says EPP what chip is on it?
[18:08:56] <MarkusBec> most pci cards dont suppoer epp

[18:10:29] <pfred1> :)
[18:11:09] <pfred1> apparently you're not the only one to have problems with this device
[18:13:55] <MarkusBec> hmm
[18:14:06] <MarkusBec> dmesg says the card is on spp mode
[18:16:34] <jdh> there is an app that will try to force epp mode
[18:16:43] <jdh> jon elson's site maybe
[18:16:56] <MarkusBec> jdh: what card do you use
[18:17:39] <jdh> don't recall offhand. it is at home and I am not.
[18:17:55] <MarkusBec> cat /proc/sys/dev/parport/parport0/modes says
[18:18:05] <MarkusBec> pcspp,tristate
[18:18:09] <MarkusBec> narf
[18:18:51] <MarkusBec> no epp
[18:20:46] <MarkusBec> http://kent-vandervelden.blogspot.de/2014/08/linux-parallel-port-cards.html
[18:21:22] <pfred1> MarkusBec right now what I'm seeing doesn't look good for that card
[18:21:30] <pfred1> http://kent-vandervelden.blogspot.com/2014/08/linux-parallel-port-cards.html
[18:21:37] <pfred1> it landed in the faled column
[18:21:43] <pfred1> failed even
[18:22:00] <MarkusBec> yes
[18:22:05] <andypugh> The LinuxCNC driver assumes that it can put a card into EPP mode, and tries to do so.
[18:22:10] <MarkusBec> the fixed the driver
[18:22:13] <pfred1> though on the plus side he has some that work
[18:22:17] <MarkusBec> no it works but no epp
[18:22:49] <pfred1> I know when I bought mine I went with a recommended one i think I have a netmos?
[18:22:56] <MarkusBec> hm buy a parport kart
[18:23:03] <MarkusBec> or direktly a new mesa card
[18:23:32] <pfred1> it was some chip that in the documentation it said it worked
[18:23:37] <andypugh> A 5i24 will connect the existing 7i43 headers directly.
[18:23:56] <pfred1> yeah skip the pport if you can
[18:24:33] <MarkusBec> 7I92 119€
[18:25:13] <andypugh> http://eusurplus.com/index.php?route=product/search&search=6i24&sub_category=true&description=true
[18:25:49] <MarkusBec> the pci is not in the CNC
[18:26:06] <MarkusBec> flatkable are not the best :)
[18:26:24] <andypugh> MarkusBec: The 7i92 needs a breakout board, but you can ply your existing stuff from the 7i43 directly into the 6i24
[18:26:25] <MarkusBec> if the pc is not in the machine
[18:26:46] <MarkusBec> breakout board is not the problem
[18:26:56] <andypugh> Hmm, OK. That it one good thing about the 7i43.
[18:27:18] <MarkusBec> pcw_home: said ther will be a 7i43 version with ethernet in the future
[18:27:23] <Cromaglious_> got in all the parts to make the PID pwm rpm control
[18:27:33] <andypugh> It’s probably best to just get a PCI parport card that works in EPP mode.
[18:27:41] <Cromaglious_> now to fabricoble together a mount for the hall effect sensor
[18:27:41] <MarkusBec> http://www.shop.cncmonster.de/LinuxCNC/FPGA-Karten/Ethernet/7I80HD-16-Ethernet-Anything-I-O-card::390.html
[18:27:55] <MarkusBec> 7i80 will work as plugin
[18:28:11] <andypugh> Ah, yes. I had forgotten that
[18:28:12] <MarkusBec> but i dont net twice the IO for twice the price
[18:28:19] <MarkusBec> need
[18:29:01] <andypugh> MarkusBec: Cheaper here: http://eusurplus.com/index.php?route=product/product&product_id=627&search=7i80&description=true&sub_category=true
[18:33:49] <pfred1> this is the parallel port card i have 01:00.0 Communication controller: NetMos Technology PCI 9815 Multi-I/O Controller (rev 01)
[18:34:17] <MarkusBec> i think a new mesa card will be the better decision
[18:34:25] <pfred1> sure
[18:35:50] <pfred1> none of the NetMos cards are pci-e anyways
[18:36:10] <MarkusBec> StarTech PEX1P
[18:36:15] <MarkusBec> Oxford Semi OXPCIe952-FBAG
[18:36:19] <MarkusBec> but 30€
[18:36:43] <MarkusBec> and a new small mesa card 100€
[18:38:33] <MarkusBec> all my other pcs dont have a parport anymore :)
[18:39:36] <gorbypark> i think i should get a mesa card, too

[18:47:11] <MarkusBec> hm found a Moschip MCS9805CV parport card
[18:47:13] <MarkusBec> pci
[18:47:29] <andypugh> MarkusBec: The 5i25 doesn’t have that many pins. What do you intend to put on the other end of the cable?
[18:47:39] <MarkusBec> i can add this to the pc of my lasercutter
[18:47:46] <MarkusBec> and use it with the mill
[18:47:53] <gorbypark> bah. cheapest shipping option to canada is $45 USD for a plug-n-go kit :(
[18:48:01] <gorbypark> that's highway robbery :(
[18:48:40] <MarkusBec> gorbypark: for canada its properbly the cheapest to order directly from mesa
[18:48:58] <gorbypark> MarkusBec: that's from mesa
[18:49:05] <MarkusBec> oh :=)
[18:49:38] <andypugh> gorbypark: Try http://www.mesaus.com
[18:49:43] <MarkusBec> andypugh: 4 axis 3 endstops 1 tool prop
[18:49:44] <pfred1> that's The Man sticking it to you
[18:50:01] <andypugh> MarkusBec: I meant in terms of interface hardware
[18:50:40] <andypugh> Normally the 5i25 is used with a 7i76 or similar, and that has a bunch of serially-adressed IO on it.
[18:51:17] <andypugh> JT-Shop: How much do you charge to ship to Canada?
[18:51:20] <MarkusBec> i think i will design my own breakout
[18:51:38] <pfred1> I made a breakout board
[18:51:44] <gorbypark> andypugh: shipping is only $24 from there....but $80 more for the kit than mesanet.com :P
[18:52:03] <pfred1> though I never tried the inputs on it yet
[18:52:21] <gorbypark> andypugh: nvm, i'm dumb, i was looking at the 7i77 kit
[18:52:25] <pfred1> I totally cheesed out on that part of it
[18:54:55] <andypugh> MarkusBec: The 5i25 has only 17 IO pins. If you make your own “dumb” breakout board without the clever stuff that the 7i76 has then you will be short of pins.
[18:55:21] <MarkusBec> 2x17
[18:55:37] <andypugh> Well, yes, if you use two cables
[18:55:53] <MarkusBec> i think i will use a 7I92
[18:55:56] <MarkusBec> with 2x17
[18:56:11] <MarkusBec> and 1 ethernet cable to the mill
[18:57:45] <andypugh> Brass is quite expensive, isn’t it?
[18:58:00] <andypugh> I am looking for 500mm x 70mm dia.
[19:00:17] <andypugh> Anyway, time to hit my “pause” button.
[19:01:31] <pfred1> now to pick just the right LED for this board
[21:09:34] <mikeh_> http://www.ebay.ca/itm/24-Values-New-Shaft-Coupling-Flexible-Coupler-Coupling-Connector-CNC-RB-/162132811934?var=&hash=item25bfde609e:m:monYE-mYhvMnCheaXCzGhLg
[21:09:46] <mikeh_> yea or nay vs lovejoy couplings?
[21:27:25] <CaptHindsight> mikeh_: http://www.lovejoy-inc.com/thecouplinghandbook_part1.aspx

[21:30:46] <CaptHindsight> http://machinedesign.com/mechanical-drives/10-tips-using-couplings-your-application
[21:31:02] <CaptHindsight> http://machinedesign.com/archive/prevent-coupling-failure-good-design-installation-and-maintenance
[21:31:18] <CaptHindsight> mikeh_: so it depends on the application
[21:49:14] <gorbypark> CaptHindsight: (mikeh_ is me on my other computer) small (seig X2) stepper to ball screw connection. I'm trying to elimanate as much backlash as possible, and there is an ever so slight play in my lovejoys
[21:50:11] <gorbypark> maybe only a half degree of slop, but i can feel it when i put them in my hand and rotate back and forth
[22:00:31] <CaptHindsight> gorbypark: and nothing is binding?
[22:03:49] <CaptHindsight> is it play due to worn coupling spider or jaws?
[22:08:37] <gorbypark> CaptHindsight: they're fairly new
[22:08:49] <gorbypark> and even my z axis has it...which is hardly used
[22:08:57] <gorbypark> i think it's just the design of them
[22:12:29] <dioz> anyone in here work in any trades?
[22:14:57] <MacGalempsy_> i try to trade things all the time
[22:15:04] <Jymmm> Only took 27 hours to get a new battery *sigh*
[22:15:42] * Jymmm blames CaptHindsight
[22:16:04] <MacGalempsy_> probably a wise direction to point
[22:18:27] <Jymmm> AAA just really FUBAR'ed this time
[22:20:57] <Jymmm> My last AAA battery lasted 7 years, so can't complain there. I got a 700 CCA (which tested at 1046 CCA) for $142 out the door (well, delivered) and comes with a 3yr free replacement + 3yr prorated.
[22:35:58] <Jymmm> Nice... a PVC roller bearing https://www.youtube.com/watch?v=79zXWIEflOg
[22:42:17] <Cromaglious_> friends don't let friends buy Wal Mart Batteries
[22:42:32] <Cromaglious_> Most I ever got out of one was 9 months
[22:43:11] <Jymmm> ouch
[22:43:35] <Jymmm> yeah, it seems everything "black box" is crap anymore
[22:43:58] <Cromaglious_> I've been having decent luck with Autozone Duragold's I get Atlas if I can find them
[22:44:49] <Cromaglious_> In California I've gotten 12 years out of an Atlas battery
[22:44:52] <Jymmm> I dont see "Atlas" on their website
[22:45:07] <Cromaglious_> seperate brand...
[22:45:08] <Jymmm> I'm in NorCal
[22:45:49] <Cromaglious_> May have been a regional brand...
[22:45:55] <Jymmm> They have "Duralast Platinum"
[22:46:16] <Jymmm> but no Duralast Atlas"
[22:47:14] <Cromaglious_> Atlas is a seperate brand.. last one I got was at San Pablo Autoparts
[22:48:05] <Cromaglious_> Duralast Gold's work pretty good though
[22:48:33] <Jymmm> Well, I'll stick with AAA for now. They'll come out at 3AM and replace it.
[22:50:32] <Cromaglious_> I always have a dry battery ready to go... Type 24 Side terminal with adapters. so it'll go into a GM or anything else
[22:50:47] <Cromaglious_> add water... ready charged battery
[22:52:07] <Jymmm> "Type 24"??? You mean BCI Group 24?
[22:52:24] <Jymmm> "Just add water"? I've never seen such a battery, link?
[22:53:27] <Cromaglious_> Dry charged battery.. no water in it
[22:53:39] <Jymmm> Cromaglious_: link?
[22:53:47] <Jymmm> google show nada
[22:54:57] <Cromaglious_> ack.. acid and water is seperate... add water and acid when you need the battery...
[22:55:11] <Cromaglious_> I'm getting old...
[22:55:34] <Cromaglious_> but it can sit on the shelf for years and it's as good as the day you bought it
[22:57:04] <Cromaglious_> http://support.rollsbattery.com/support/solutions/articles/427-activating-instructions-dry-charged-batteries-detailed-
[22:59:18] <Cromaglious_> Dry Charged batteries are pretty common around fishing boats. kinda hard to get a spare battery out on the high sea. keep a spare with scid and water ready next to it for when you need it
[23:12:10] <Jymmm> Yeah, just haven't seen any (in decades?) around here
[23:12:26] <Jymmm> a motorcycle one maybe
[23:20:14] <MacGalempsy_> i am excited to finally get the mix down. this new cement dries in 24 hours
[23:24:37] <Jymmm> MacGalempsy_: keep it wet for a few days though =)
[23:24:48] <Jymmm> ...to a week
[23:27:00] <MacGalempsy_> the cement shows 24hr strength of 6000psi
[23:27:49] <MacGalempsy_> after that, I will use a lightbulb with a dimmer switch to slowly raise the temperature to 150c and hold it for 24hrs
[23:27:50] <Jymmm> MacGalempsy_: It's not strength, it's to prevent it from cracking
[23:28:19] <Jymmm> fast cure is for things like fence posts, not slabs.
[23:28:32] <MacGalempsy_> you are thinking portland cement
[23:28:40] <MacGalempsy_> this is calcium aluminate cement
[23:29:10] <Jymmm> you never said either way
[23:31:00] <MacGalempsy_> this latest mix looks like pottery clay after it has set
[23:31:55] <MacGalempsy_> the problem with portland is it vaporizes at 500f
[23:32:10] <Jymmm> ah
[23:32:25] <MacGalempsy_> and that is not hot enough to melt the rest of it together
[23:32:57] <MacGalempsy_> did you see the ternary diagram I made of the composition?
[23:33:30] <MacGalempsy_> https://flic.kr/p/NvcAVH
[23:34:07] <MacGalempsy_> the water volume in the test batch had to be doubled because it was too stiff
[23:37:11] <MacGalempsy_> the perlite mixes were a lot lighter, but we are aiming for 50deg shy of boiling silica
[23:37:48] <MacGalempsy_> which is 2230c! lol
[23:38:13] <Jymmm> for?
[23:38:43] <MacGalempsy_> bronze
[23:39:01] <MacGalempsy_> maybe some steel. mostly just for scientific bragging rights
[23:39:04] <Jymmm> ah
[23:39:54] <MacGalempsy_> the grog and the cement will both help with the cracking
[23:41:30] <MacGalempsy_> this mix is considered an ultra-low cement castable refractory.
[23:42:45] <MacGalempsy_> how is the garage heater coming along?
[23:44:19] <Jymmm> In limbo, had to deal with car battery for last 27 hours. considering a barrel stove and JSUT watching a video as we speak https://www.youtube.com/watch?v=sxBWbovry7Y
[23:45:03] <Jymmm> I want to have a reburner is posisble, and a smaller 25 gal drum stove might be nice, but want uprigth, not on side.
