[00:14:58] <CaptHindsight> I only got 2-3 years out of my last Yellow Optima battery
[00:15:15] <Jymmm> ouch
[00:15:16] <CaptHindsight> not sure who makes a good car battery anymore
[00:15:30] <Jymmm> I hear ya
[00:15:47] <CaptHindsight> once they started making them south of the border they went downhill
[00:16:19] <Jymmm> I got 7 years out of my last AAA battery. this one is the same and was $142
[00:17:06] <CaptHindsight> https://en.wikipedia.org/wiki/AAA_battery
[00:17:56] <Jymmm> CaptHindsight: http://aaa.com/
[00:18:28] <CaptHindsight> AAA is really popular in CA
[00:19:17] <CaptHindsight> I wonder who makes them?
[00:19:22] <Jymmm> their dispatch is in Utah =)
[00:19:39] <Jymmm> oh, I can find out tomorrow, it's on the label
[00:20:28] <Jymmm> it's some four letter compan name that begins with a D
[00:23:14] <CaptHindsight> https://www.summitracing.com/parts/xsp-d3400/overview/
[00:25:56] <CaptHindsight> http://4xspower.com/shop/d-series/d7500/ MSRP – $849.99 12V AGM Battery, Max Amps 6,000A, CA: 1700, Ah: 140, 5000W / 7500W
[00:30:41] <CaptHindsight> I wonder if the automotive Lithium battery are made well
[00:33:27] <SpeedEvil> 'the' ?
[00:34:03] <CaptHindsight> any supplier
[00:34:27] <SpeedEvil> Well, tesla batteries are quite reliable.
[00:34:55] <CaptHindsight> if they are half assed together since I have only seen them with a 2 year warranty so far
[00:35:56] <CaptHindsight> does Tesla make replacement auto batteries?
[00:37:08] <SpeedEvil> no
[00:37:38] <SpeedEvil> you could make quite reliable lithium 12V replacement batteries.
[00:37:56] <SpeedEvil> How you work out if your one is so, without waiting years is problematic.
[00:41:15] <CaptHindsight> SpeedEvil: are you near Islay? (<100km)
[00:43:45] <SpeedEvil> No
[00:43:57] <SpeedEvil> opposite side
[00:45:59] <mikeh_> anyone know the name of that 3m double sided tape that's suppost to be really good?
[00:47:01] <Jymmm> $3000 and only a 1yr warranty?! http://4xspower.com/shop/lithium/xs30k/
[00:47:21] <Jymmm> mikeh_: carpet tape?
[00:48:15] <mikeh_> i think i might be thinking of 3M VHB taoe
[00:48:18] <mikeh_> tape*
[00:48:23] <CaptHindsight> http://www.3m.com/3M/en_US/company-us/all-3m-products/~/All-3M-Products/Tapes-Adhesives/Industrial-Tapes-and-Adhesives/Double-Sided-Bonding-Tapes/

[00:56:46] <Jymmm> CaptHindsight: http://www.dekabatteries.com/
[01:02:53] <Jymmm> CaptHindsight: It looks like Lowes sells Deka brand batteries
[01:17:23] <CaptHindsight> what I want is a battery made as well as the Optimas from 10 years ago
[01:18:28] <Jymmm> CaptHindsight: Then buy an iton battery, that should last 100 years or so
[01:18:31] <Jymmm> iron
[01:25:53] <CaptHindsight> I'm going to use forklift batteries with a backup generator powered by a thorium reactor
[01:28:05] <XXCoder> hey guys
[01:28:18] <XXCoder> what is okay make of car for used car, say in $3k range?
[01:29:13] <CaptHindsight> do you want one that is reliable? like toyota, honda?
[01:29:27] <XXCoder> a to b reliable yep heh
[01:30:12] <CaptHindsight> depends on where you live and how rust free it might be
[01:31:03] <XXCoder> for foreverain state, cars is rust-free
[01:31:05] <XXCoder> we dont use sal
[01:31:07] <XXCoder> salt
[01:31:11] <CaptHindsight> I've purchased land Cruisers for $3k that had lots of life left without having to do much to them
[01:33:14] <CaptHindsight> most the US cars are easy to fix and the parts are cheap
[01:33:25] <XXCoder> im tired of fixing em
[01:33:27] <CaptHindsight> you might have to do it often
[01:33:37] <XXCoder> I just want one that works fine for in least a year
[01:33:51] <XXCoder> maybe 2, then I will finally get an elioi
[01:34:35] <CaptHindsight> I get well over 300K miles with Toyota's if I get them before somebody has attempted a rebuild of some sort
[01:35:27] <XXCoder> ok
[01:36:13] <CaptHindsight> 300K is about trans rebuild time for an automatic if cared for
[01:37:05] <XXCoder> my nissan quest is nearly 200k
[01:37:12] <CaptHindsight> 300-400K for an engine
[01:38:11] <CaptHindsight> great for a Nissan, they tend to have purposely finicky ECU's
[01:38:46] <CaptHindsight> 10% wear on the pre-cat, oh there goes the code from the O2's
[01:39:18] <CaptHindsight> electric motor mounts that aren't fused
[01:39:46] <CaptHindsight> IAC motor that isn't fused
[01:40:11] <CaptHindsight> the factory doesn't want them to last
[01:40:36] <XXCoder> wer eally need some cyalyist is not platanium
[01:41:21] <XXCoder> *that is not
[01:45:22] <CaptHindsight> IMHO Toyota's maxed out in the mid 90's for reliability
[01:45:54] <CaptHindsight> at least for LC's and pickups
[01:50:27] <Jymmm> jthornton: DIY Spyder... https://www.youtube.com/watch?v=1EQAruogjVo
[01:54:44] <CaptHindsight> Spyder's have 2 front wheels
[01:54:53] <CaptHindsight> he ran it backwards
[01:56:37] <Jymmm> CaptHindsight: I know =)
[01:56:52] <Jymmm> CaptHindsight: I think jthorntoncan figure it out ;)
[01:57:06] <CaptHindsight> can't you find a vid of it running backwards?
[01:57:12] <Jymmm> (I hope ;)
[01:57:30] <Jymmm> reverse the wires?
[01:58:00] <CaptHindsight> Jymmm: when does your fall arrive?
[01:59:02] <Jymmm> CaptHindsight: after the 81st beer?
[01:59:16] <XXCoder> just 81?
[01:59:24] <XXCoder> dont seem to be effective party
[01:59:30] <Jymmm> XXCoder: 40's
[01:59:36] <CaptHindsight> http://www.goodnewsnetwork.org/sleek-3-wheeled-car-to-get-84-mpg-and-sell-in-us-for-just-6800/
[02:00:29] <XXCoder> not 6800 anymore unfortunately. now $7,200 for basic model
[02:00:40] <CaptHindsight> close enough
[02:01:15] <Jymmm> AND you need a motorcycle license for it =)
[02:01:49] <XXCoder> n.
[02:01:51] <XXCoder> *no.
[02:02:09] <Jymmm> Three wheel? Yep =)
[02:02:13] <XXCoder> its not motorcycle. its autocycle. new type
[02:02:50] <XXCoder> trust me, been following elio for years
[02:03:11] <XXCoder> I actually sat in elio P3
[02:03:20] <XXCoder> the grey one
[02:03:27] <CaptHindsight> no option for disintegration ray
[02:03:36] <XXCoder> oh thats easy
[02:03:41] <CaptHindsight> or side facing EMP
[02:03:44] <XXCoder> just consult your local mad scientist
[02:04:12] <XXCoder> now, actually getting there is dangerous as they tend to be far off, alone, in well defensed base.
[02:04:20] <XXCoder> good luck
[02:05:14] <CaptHindsight> Pep Boys anticipated to be "Official Service Center" for service and warranty work
[02:05:17] <CaptHindsight> no thanks
[02:06:17] <XXCoder> Jymmm: lol that 9v battery trike
[02:06:49] <CaptHindsight> 3 cyl., .9 liter, liquid-cooled, automotive engine 55 HP and 55 LB-FT of torque
[02:07:19] <Jymmm> CaptHindsight: sounds like a geo metro
[02:07:24] <CaptHindsight> 12:1 Compression? with regular unleaded
[02:07:48] <XXCoder> Jymmm: they planned to use geo 3 cyl engine, but they couldnt do 84 mpg with it
[02:07:54] <XXCoder> so they designed their own. thats one of delays
[02:08:07] <Jymmm> 84MPG AND air conditioning... I'd buy one
[02:08:30] <XXCoder> they recently tested air conditioning, both ways. passed
[02:08:46] <CaptHindsight> the problem around here will be not getting run into
[02:08:47] <XXCoder> torture test of 110f, with sun lamps slanted into car with 30 degrees
[02:09:50] <Jymmm> CaptHindsight: I figure it as an enclosed motorcycle
[02:10:13] <XXCoder> it isnt.
[02:10:19] <XXCoder> interior is very roomy
[02:10:24] <archivist_> just a copy of an old idea, Morgan car and Reliant cars
[02:10:26] <XXCoder> and drive like car
[02:11:11] <XXCoder> archivist_: reliant robin ouch
[02:11:17] <XXCoder> hope elio wont end up with that rep
[02:11:36] <XXCoder> good thing front is 2 wheels not back lol
[02:11:45] <archivist_> http://www.morgan-motor.co.uk/3-wheeler/
[02:11:49] <CaptHindsight> http://db.carbuzz.com/images2/260000/3000/600/263684.jpg
[02:12:07] <XXCoder> CaptHindsight: lol I always wanted to get one of those.
[02:12:42] <archivist_> and https://en.wikipedia.org/wiki/Bond_Bug
[02:13:13] <archivist_> aint nothing new
[02:13:18] <XXCoder> yeah
[02:13:32] <XXCoder> they are just trying to get high mpg mostly american made car
[02:13:43] <CaptHindsight> http://previews.123rf.com/images/spondicious/spondicious0710/spondicious071000001/1842316-Old-3-wheel-car-made-of-fibreglass-much-unloved-Stock-Photo.jpg
[02:13:44] <archivist_> nickname over here was plastic pig
[02:13:47] <XXCoder> 90% american made is a requirement.
[02:14:31] <XXCoder> bond bug does look cool. pribably drives like shit
[02:14:38] <archivist_> they tip over easily
[02:14:50] <XXCoder> yeah thats why elio is 2 wheel front not back
[02:15:10] <miss0r> archivist_: you saw my godawfull drillpress table yestarday. do you have some good idea how to mend it?
[02:15:33] <XXCoder> https://www.youtube.com/watch?v=YYbprouVRIw
[02:15:59] <archivist_> miss0r, I never see anything on shitty google drive
[02:16:17] <miss0r> i'll do a picturepaste then
[02:16:34] <archivist_> it is a pile of steaming js
[02:17:41] <miss0r> http://picpaste.com/20161023_072605-KjR2YWoH.jpg
[02:18:25] <miss0r> just got it setup yesterday. The previous owner did a number on it. and at some point poured in some epoxy to somewhat mend it
[02:19:23] <XXCoder> looks bad
[02:19:30] <miss0r> it realy is.
[02:19:39] <XXCoder> well
[02:19:44] <XXCoder> first thing I'd do is clean it
[02:19:50] <miss0r> but its a nice Strands s68l drillpress, with a x-y table.
[02:20:05] <miss0r> I have cleaned it now, and taken the table off.
[02:20:30] <miss0r> but, contrary to popular believe, 'cleaning' does not remove the holes :)
[02:20:52] <XXCoder> sure it can. just buy ACME hole wiper
[02:20:55] <XXCoder> ;)
[02:21:11] <miss0r> :]
[02:21:17] <archivist_> you could make a new casting
[02:21:22] <Cromaglious_> miss0r, wow they didn't understand the concept of spoiler board did they
[02:21:27] <XXCoder> thats an idea arch
[02:21:56] <miss0r> archivist_: I don't have the means of casting iron, not even aluminium at this point
[02:21:57] <Cromaglious_> start brazing...
[02:22:30] <archivist_> you only need make the pattern, then send the pattern to a foundry
[02:22:34] <miss0r> Cromaglious_: I'm worried I will have to put too much heat into the table, with the amount that needs added
[02:22:59] <archivist_> pattern making can be fun
[02:23:25] <miss0r> archivist_: I must admit hoping for an inhouse solution. :) I just spend a fortune on tools a few days ago, not alot left :)
[02:23:34] <Cromaglious_> think I figured out a way to fix my sewing machine... get a piece of all thread and hold it together with nuts on the all thread, then clamp the all thread to the vice... then I'm not dumping all the heat into the vice...
[02:23:45] <XXCoder> miss0r: is it unusable or?
[02:24:10] <Cromaglious_> I was clamping the piece in the vice and it was sucking too much heat away so it wouldn't braze
[02:24:28] <archivist_> miss0r, probably cheaper than you think to get it cast http://www.collection.archivist.info/searchv13.php?searchstr=BK170
[02:24:39] <miss0r> XXCoder: Well, not unusable persay. But it is going to replace a crappy generic chinesium drill press. and with this uneven table, I'm not much better off
[02:24:56] <Cromaglious_> fun part is making a pattern the correct size to account for skrinkage
[02:25:06] <XXCoder> maybe like crom said add spiler board?
[02:25:16] <archivist_> shrinkage is a known art
[02:26:01] <Cromaglious_> with cast iron it's not so back... with AL it's pretty bad
[02:26:06] <Cromaglious_> s/back/bad/
[02:26:13] <miss0r> I could mill a new table for it using foam - that would be no problem. But I don't know of any foundrys in my neighboorhood. even in Denmark to be honnest
[02:26:24] <archivist_> with some goo you can enlarge the original part to use as a pattern
[02:26:30] <XXCoder> Cromaglious_: cant just send correc size model and they correct it for strunkage?
[02:27:06] <Cromaglious_> easy enough to scale it in CAD
[02:27:51] <Cromaglious_> time for bed... took all my pills bleh....
[02:28:17] <miss0r> I had a thought thou. How idiotic would it be to mill a new table, where the dovetails underneath are bolted to the bottom of the table? (Then I have stock material I could use off the bat)
[02:28:36] <archivist_> I did one for a clock base http://www.collection.archivist.info/archive/DJCPD/PD/2006/2006_05_02_Leawod/P4262333.JPG
[02:28:57] <XXCoder> nice!
[02:28:57] <miss0r> Cromaglious_: I hate the time difference with people chatting in here, I just started my day ;)
[02:29:13] <XXCoder> 12 am here. good morning
[02:29:41] <miss0r> am... is that the morning or the nighttime? :)
[02:30:02] <miss0r> archivist_: is that brass?
[02:30:06] <XXCoder> both apparently lol
[02:30:32] <archivist_> yes this was the whole project, note how old the mill was http://www.collection.archivist.info/searchv13.php?searchstr=skeleton+clock
[02:31:47] <miss0r> Old mills gets stuff done aswell :)
[02:32:11] <archivist_> I think I allowed too much shrinkage, took a while to mill it down to size
[02:33:04] <miss0r> and you spend hours upon hours polishing that thing :)
[02:33:38] <XXCoder> archivist_: oilstone?
[02:35:34] <archivist_> spent hours filing the machine marks out first
[02:35:56] <archivist_> then wet and dry up the grades
[02:36:24] <miss0r> I had another thought with this drill press table. What if I milled the surface down do the height where the t-slots widen, then add three peices of material bolted down on top of that ? that should make for a nice table
[02:36:27] <archivist_> the hard bit is keeping the edge square
[02:37:20] <archivist_> that mill went to the scrap yard 2009
[02:39:28] <miss0r> archivist_: you seem to have alot of experience with casting. If I machine out the two outer reisers of the table, and only machining the middle half way down, do you think the table will twist on me alot?
[02:40:10] <Jymmm> CaptHindsight: https://www.youtube.com/watch?v=vobEBqEISh8
[02:40:47] <Jymmm> CaptHindsight: sure enough... geo metro engine used in the prototype =)
[02:40:56] <archivist_> may may not, if it was heat treated and rested when new between rough and final machining it may be stable
[02:41:07] <XXCoder> Jymmm: yeah, they did plan to use it in production
[02:41:12] <XXCoder> but changed mind
[02:41:25] <miss0r> archivist_: I guess theres no way of knowing?
[02:42:27] <archivist_> not without doing it :)
[02:42:51] <miss0r> a few of thoes holes actualy made it all the way through the table! I can see the epoxy repair covering a ~30mm diameter hole on the bottom
[02:43:52] <miss0r> atleast I enjoy machining cast iron... I will give it a try, I can always machine it back to size, unless it folds in on itself...
[02:44:15] <miss0r> I'll look at that later. I Have to get some real work done. see you around
[02:45:45] <Deejay> moin
[02:46:58] <Jymmm> Deejay: hi
[02:47:09] <Jymmm> XXCoder: $1300 ?! http://www.cocoamotors.com/
[02:47:52] <XXCoder> Jymmm: yeah apparently. lol
[02:48:12] <Jymmm> it can be the spare tire for the eilo
[02:48:15] <XXCoder> I wouldnt trust those wheels anywhere in usa silkwalk and roads.
[02:49:07] <XXCoder> *side
[02:59:46] <archivist_> rofl the html is patently wrong on that cocoamotors page, the scripts are before the div and nothing refers to the div name
[04:29:04] <Meduza> I am quite intrested in the Ethernet connected Mesa cards, anyone in here has something to say about them?
[05:09:40] <XXCoder> https://www.thingiverse.com/make:262293
[05:14:02] <archivist_> Meduza, I dont have one, not seen any problems
[05:14:21] <archivist_> or heard of problems
[05:16:37] <Meduza> to me a ethernet connected control card with a FPGA really makes linuxcnc a much more intresting system, getting away from the PCI cards and parallell ports
[05:20:00] <archivist_> the ethernet and pci are related really, main difference is the communications and some timing
[05:25:33] <gonzo_> as long as it is supported in the hostmot releases. (I went for the 7i90, but didn't realise the sw was still in dev, so had to wait to use it)
[05:26:57] <gonzo_> for completeness, I'll add, that was a while ago. the 7i90 looks to be fully supported now
[05:33:44] <enleth> Meduza: remember that ethernet, if used properly on a full-duplex point-to-point link (no switches) can get pretty darn close to realtime
[05:34:01] <enleth> "used properly" means mostly tight control of buffering
[05:35:39] <archivist_> the other thing done is the fpga card now has a pll to make sure timing is right, probably better realtime now
[05:36:36] <enleth> Meduza: there are several industrial buses based on ethernet and the most important changes they introduce is clock synchronization and deterministic collision control instead of the random back-off mechanism of the garden variety ethernet
[05:37:59] <enleth> but those are meant for full-fledged networks that maintain RT
[05:39:36] <enleth> a direct link between two decent quality consumer ethernet NICs with buffering under strict control works just as well
[05:39:59] <archivist_> some run independent trajectory planners, not sure how well they feedback on one slowing down
[05:48:00] <jthornton> morning
[05:48:32] <XXCoder> hey jthornton
[05:48:51] <jthornton> what's up this morning
[05:48:55] <XXCoder> https://www.thingiverse.com/make:262292 and https://www.thingiverse.com/thing:1356547 heh
[05:49:47] <XXCoder> now making 2 of https://www.thingiverse.com/thing:1601160 - last one before week.
[05:50:29] <jthornton> making any progress on diameters?
[05:50:56] <XXCoder> figured I could break it apart and test
[05:50:59] <XXCoder> it fits good
[05:56:01] <XXCoder> jthornton: sizes is little wrong but matched. so the xy adjustment is correct. though need to fix nozzle size maybe
[05:56:09] <XXCoder> oh yeah
[05:56:27] <XXCoder> I got achcol and cotton wipes, cleaned glass. glue goes on much easier and very good stick now
[05:57:31] <jthornton> those print fans really made a difference for me now that I understand what they do and how to run them
[05:57:51] <XXCoder> it does!
[05:58:00] <XXCoder> I had to use big fan to keep temperate controlled
[05:58:18] <XXCoder> and you can see that theres still some issues in that fracial structure.
[05:58:37] <jthornton> your clue about creeping was a big help in understanding what was going on
[05:59:14] <XXCoder> theres other kind of heat creeping but we wont get that one as we both have fans blowing over top of hotend so filiment dont get warm on top.
[06:00:33] <jthornton> I want to build a 12" x 12" x 12" CoreXY
[06:00:57] <XXCoder> if you wanna print fracial stucture I linked to above, the heat creep control is a must because its strunking to point constually. which means heat gets closer and closer.. heh
[06:01:26] <jthornton> http://www.thingiverse.com/thing:650905
[06:01:50] <XXCoder> other guy linked to it lol
[06:02:00] <XXCoder> in reprap
[06:03:23] <jthornton> yea, I kinda jumped him for the bedspring comment yesterday
[06:05:46] <XXCoder> hmm ok heh
[06:07:17] <XXCoder> you used achcol to clean glass?
[06:07:32] <jthornton> windex
[06:07:44] <XXCoder> thats based on achcol so likely to work
[06:07:50] <XXCoder> one guy recommanded vingear
[06:07:52] <XXCoder> plain
[06:07:57] <XXCoder> in order to make print stick
[06:08:09] <XXCoder> as long as bed is warm. havent tried lol
[06:08:15] <jthornton> with the glue stick it sticks too good lol
[06:08:22] <XXCoder> heh
[06:08:34] <XXCoder> I bought cheap blade paint scaper
[06:08:36] <jthornton> I'm using white rain hair spray unless it has a small foot print
[06:08:46] <XXCoder> it works very well on removing glue from glass
[06:09:04] <XXCoder> denatured achcol to degrease it
[06:09:48] <gonzo_> in labs they often use lemon juice
[06:10:16] <XXCoder> my guess is that vingear or lemon adds micro-texture that print sticks to.,
[06:12:25] <jthornton> https://github.com/zelogik/AluXY
[06:17:10] <Tom_L> yeah they use a paint scraper to remove at the Uni
[06:17:29] <XXCoder> it seemed effective.

[09:46:18] <MattyMatt> http://www.ebay.co.uk/itm/Job-Lot-x-4-ELO-Touch-Systems-ET1547L-6UWC-1-POS-15-LCD-Touch-Screen-Monitor-/252595854849 too rich for me, but looks flippable
[09:48:59] <MattyMatt> is there a front end that runs on android yet?
[09:51:21] <Jymmm> MattyMatt: As soon as you create one there will be.
[09:51:30] <MattyMatt> yow. that soon?
[09:53:32] <MattyMatt> there's a decent one for repraps but not open source unfortunately
[09:55:12] <MattyMatt> and I've never seen a PC that can act as a USB client
[09:57:21] <Jymmm> Do realize that linuxcnc can/does control indistrial equipment that size of a room, not just something that can sit on your kitchen table. Do you REALLY want something that can crush your body into a pancake to be controlled via easily hackable wifi on a smart (dumb) phone with an I/O that allows people to butt dial?
[09:58:04] <MattyMatt> £26 tablet has usb otg
[09:58:20] <MattyMatt> and if it's velcroed to the machine there's no buttdial
[09:58:44] <Jymmm> You underestimate the the stupidity of people.
[09:58:44] <MattyMatt> leaving wifi on is an optional risk
[10:02:56] <MattyMatt> tbh, I'd rather have a decent SBC with arm and simple RTOS than a PC as motion control hardware
[10:03:05] <MattyMatt> even for a big machine
[10:03:28] <MattyMatt> unless that PC was a PC-104 etc in a stack of mesa cards
[10:05:31] <MattyMatt> hi jt
[10:07:00] <skunkworks> crazy talk ;)
[10:26:29] <IchGucksLive> hi
[10:26:44] <IchGucksLive> rain the whole day in germany
[10:26:54] <IchGucksLive> tirered
[10:27:27] <IchGucksLive> MattyMatt: there is a wintablet cnc that runs perfect on most interfaces
[10:27:46] <IchGucksLive> editnc can do this perfect on a 80pond tablet
[10:28:27] <IchGucksLive> till later
[10:55:51] <Jymmm> Is there any reason why brass compression fittings wouldn't work on SS tubing?
[10:57:56] <Jymmm> I dry fit some SS tubing I have on one, and it felt like there was some "slop" compared to typical copper tubing.
[11:07:28] <sync> Jymmm: inside vs outside calibrated?
[11:08:04] <archivist> some tubing is not designed for pressure work, diameters vary, check how the tube was made (seam v extruded etc)
[11:10:52] <Jymmm> sync: I *think* the Ss is just more "precisely" made, compared to good old fashion off the shelf copper tubing.
[11:11:51] <Jymmm> archivist: Thanks, I'll check for seams today. I believe this stick was for medical gasses, but don't recall for sure.
[11:11:53] <archivist> there is a lot of decorative SS tubing
[11:12:54] <archivist> beware of different metals and corrosion, might be better to get the right fittings
[11:14:19] <Jymmm> Oh, this wasn't decorative, I got it from a SS pipe supplier because it had been kinked on one end. I'm just going to run hot water through it, just didn't want it to slip off at the most inopportune time is all.
[11:14:54] <Jymmm> By hot, I mean shove it in 1400F firebox
[11:15:01] <gregcnc> JB Weld and duct tape to be safe
[11:16:25] <Jymmm> gregcnc: Would 99¢ store laytex be "good enough"? ;)
[11:16:51] <gregcnc> seems liek if it leaks and puts out the fire safety is built in
[11:16:59] <nubcake> if my BOB expects estop and limit signals to be switched to gnd i need an npn sensor, don't i?
[11:17:17] <nubcake> as i am switching a signal to v-/gnd
[11:18:08] <Jymmm> gregcnc: Well.... at the fitting point it would well be far away from the firebox to be able to do that =)
[11:19:45] <gregcnc> galvonic corrosion came to mind, but the potential between the two metals is small.
[11:20:16] <Jymmm> gregcnc: ok cool, good to know.
[11:20:52] <Jymmm> gregcnc: It's not THAT big a deal, I was mostly asking in general is brass fitting worked on SS tubing.
[11:21:02] <Jymmm> s/is/if/
[11:21:16] <gregcnc> get a bigger wrench if it leaks
[11:22:11] <Jymmm> ...and silly putty
[11:24:25] <archivist> only sensible putty need apply
[11:25:28] <gregcnc> obviously mixing them is discouraged anywhere you read
[11:25:36] <Jymmm> I'm going to turn one of these into a check valve as the body of it unscrews; PE tubing on one end, SS on the other, just need to tap the hole the valve stem comes out of and insert a set screw... https://www.amazon.com/LASCO-17-0995-4-Inch-Compression-Brass/dp/B008E33VA6
[11:58:17] <IchGucksLive> hi
[12:17:25] <Tom_L> Jymmm replacing the ball with a ball bearing and spring?
[12:17:49] <Tom_L> likely not enough flow around the ball for that to work
[12:22:15] <CaptHindsight> what's the gimmick on the Evolution cold saws https://www.amazon.com/dp/B000WEORGM/ref=psdc_1026922_t3_B000IHXOKI
[12:23:10] <CaptHindsight> the 14" steel cutting blades are only ~$80
[12:23:11] <Tom_L> gimmick?
[12:23:47] <IchGucksLive> CaptHindsight: only the price
[12:23:54] <CaptHindsight> do the blades only fit their saws or something?
[12:24:24] <Tom_L> read the fine print for the arbor size
[12:24:25] <IchGucksLive> nubcake: around
[12:24:43] <SpeedEvil> http://www.ebay.co.uk/itm/Rage-355mm-Replacement-Multipurpose-Circular-Saw-Blade-For-the-Rage2-Cut-Off-Saw-/401116893958?hash=item5d646e1306:g:SWUAAOSw~oFXLL~U
[12:24:46] <SpeedEvil> 25.4mm
[12:24:51] <SpeedEvil> *2.2mm thick
[12:24:55] <SpeedEvil> seems pretty boring
[12:25:09] <SpeedEvil> 1600RPM is way slower than most saws of the sort
[12:25:20] <CaptHindsight> Blade life is roughly 750 cuts
[12:25:28] <CaptHindsight> so about 10 cents per cut
[12:25:42] <Tom_L> any ole chop saw will work
[12:25:46] <Tom_L> get a fine blade
[12:26:17] <Tom_L> or an abrasive blade
[12:26:36] <SpeedEvil> claims to last 10* abrasive blades
[12:26:36] <CaptHindsight> so I can't use my soft pine blade on steel bar?
[12:26:45] <Tom_L> not for many cuts
[12:27:53] <IchGucksLive> band saw is always best
[12:28:03] <CaptHindsight> so they didn't do an end run around physics as we know it?
[12:28:12] <Tom_L> orchestra saws are the bomb!

[12:30:11] <Tom_L> i wonder how many english words have multiple meanings
[12:30:45] <CaptHindsight> eye donut no
[12:30:48] <Tom_L> is that for metal or manonry?
[12:31:10] <Tom_L> masonry would probably have a water pool under it
[12:31:28] <CaptHindsight> http://www.baileigh.com/abrasive-cut-off-saw-as-350m tubing is their claim to fame
[12:31:35] <Tom_L> we always just used abrasive blades for bar stock
[12:31:52] <Tom_L> bandsaw chop saw for other and one BIG band saw for everything else
[12:32:21] <CaptHindsight> Evolution seems to target the homeowner/handyman
[12:32:40] <Tom_L> and doesn't come with a 7.5hp motor
[12:33:12] <SpeedEvil> Practically speaking, 750 cuts is quite a lot for many apps
[12:33:12] <Tom_L> you're likely not gonna stall that no matter what
[12:33:17] <CaptHindsight> I want my handheld phaser
[12:35:23] <CaptHindsight> no mess or noise, well maybe just that http://www.trekcore.com/audio/weapons/tng_phaser_clean.mp3
[12:37:45] <CaptHindsight> who has a 200W AC servo motor and analog input drive for <$500?

[12:44:14] <IchGucksLive> DGMurdockIII: still on Windows
[12:44:31] <IchGucksLive> Change is needed
[12:44:38] <IchGucksLive> ;-)
[12:45:10] <DGMurdockIII> yes
[12:45:20] <IchGucksLive> CaptHindsight: how will trade come out if Donald makes it to the top
[12:45:43] <IchGucksLive> better price on Puttins hardware store
[12:46:02] <IchGucksLive> DGMurdockIII: im only kitting as germany like
[12:46:16] <DGMurdockIII> ok
[12:46:37] <IchGucksLive> If yu are here you may have a serious problem on CAD/CAM
[12:47:30] <IchGucksLive> by the way todays CNC construct https://youtu.be/AoZWKBE86g0
[12:51:03] <IchGucksLive> size is 30"x20"x15"
[12:52:32] <CaptHindsight> IchGucksLive: highly unlikely at this point
[12:53:13] <CaptHindsight> IchGucksLive: what would you expect from a child?
[12:53:47] <IchGucksLive> oh no he is best for the US Europ and RUS
[12:55:13] <CaptHindsight> best, entertainment wise?
[12:55:55] <IchGucksLive> no for entertainment we got lots of here in europ like Boris from UK
[12:57:15] <CaptHindsight> we only get conservatives here that make the finals
[12:59:08] <IchGucksLive> i like Rep more as business runs the world

[13:08:16] <DaViruz> i find the problem generally is to find decent servo drives, motors seems to be fairly plenty
[13:08:30] <DaViruz> though that is a pretty nice lot
[13:09:16] <CaptHindsight> DaViruz: finding analog input versions seems to be getting harder to find
[13:09:48] <CaptHindsight> heh, Mr. redundant strikes again
[13:10:44] <CaptHindsight> ^^ says that the hall effect sensors have been disabled by a jumper
[13:10:58] <CaptHindsight> why not just remove that jumper?
[13:11:37] <DaViruz> yeah pulse input seems to be fairly common
[13:11:46] <CaptHindsight> if they are custom parkers then they probably don't even have the hall sensors installed
[13:12:09] <CaptHindsight> pulse or (some)bus
[13:16:19] <IchGucksLive> nubcake: around
[13:17:58] <nubcake> just got back
[13:40:04] <IchGucksLive> Gn8
[14:26:18] <sync> or just run a custom drive DaViruz
[14:54:38] <FloppyDisk525> Just saw the comment about the parker motors.
[14:55:04] <FloppyDisk525> The only customs I worked with had features added or removed, but we never did anything w/ the Halls and they
[14:55:15] <FloppyDisk525> would have all had hall sensors. I guess the answer is it depends...
[14:55:48] <FloppyDisk525> Parker will probably not share the changes w/ someone calling in random.
[14:56:10] <FloppyDisk525> Maybe you can find the parker distributor nearby and get what the mods are out of them, but doubt it...
[14:56:54] <FloppyDisk525> Nice motors, though.. Probably worth a chance, suggest 0.3 less than they're asking..
[15:09:30] <CaptHindsight> FloppyDisk525: I know the seller. I might trade them a motor or two for the fix
[15:10:44] <CaptHindsight> they buy tons of auction equipment from IBM up in Minnesota
[15:11:34] <Frank_10> for servos with a cable of 5meters; whats thr cheapest option of cable i could get away with??
[15:11:53] <Frank_10> step/dir servos. 1kw
[15:12:13] <Frank_10> are shielded a must??
[15:13:46] <CaptHindsight> it's more better
[15:14:16] <nubcake> we use shielded wires on all kind of motors we install at work
[15:14:30] <CaptHindsight> high current stepper pulses are pretty noisy and will interfere with nearby electronics
[15:14:33] <nubcake> just to be safe
[15:16:09] <CaptHindsight> http://www.slack.net/~ant/bl-synth/4.harmonics.html
[15:16:57] <CaptHindsight> https://en.wikipedia.org/wiki/Square_wave
[15:17:40] <Frank_10> the dealer where i bought the servos use "super flex" cables or something similar brought from germany; 100 usd for each servo; is it a bad idea to try normal shielded cables for s router??
[15:17:57] <nubcake> super flex? O_o
[15:18:21] <nubcake> i know "Oelflex" e.g.: Oelflex CY 2.5mm²
[15:18:26] <nubcake> but never heard of superflex
[15:18:51] <CaptHindsight> if the cables flex when the machine moves then you need very flexible cables vs anything
[15:20:20] <nubcake> that's what we use the Oelflex for, isn't too expensive from what i know
[15:20:26] <Frank_10> T_T
[15:20:39] <CaptHindsight> http://machinedesign.com/cables-connectors-enclosures/when-flexible-cable-doesn-t-flex-long
[15:22:56] <nubcake> 50m 5G1.5mm² CY > ~150 Euros
[15:23:15] <nubcake> i don't know about the dimensions of your machine, but 50m should get you somewhere i'd say
[15:24:00] <CaptHindsight> Frank_10's neighbors will all know when he's running his mill :)
[15:24:02] <nubcake> depending on the motors you might need another transverse section.
[15:24:19] <nubcake> idk if that's the right word for it.. :D
[15:24:45] <nubcake> the wires mm².. is it really called transverse section?
[15:24:59] <nubcake> or is it width?
[15:25:04] * nubcake is confused
[15:26:11] <CaptHindsight> BTW this doesn't work on any bolt I've tried http://www.wishbonix.com/hex-removal-spell/
[15:26:41] <nubcake> lol
[15:27:06] <nubcake> never tried to use a hex removal on a bolt.. but interesting approach there
[15:28:44] <Frank_10> having a big flex radius could help
[15:28:54] <Frank_10> adding cable lenght
[15:28:58] <nubcake> indeed does help
[15:29:06] <nubcake> if you have the room to fit it
[15:29:29] <Frank_10> its a 2.4m router
[15:29:35] <MacGalempsy> making chips?
[15:29:57] <nubcake> hey Mac
[15:29:59] <MacGalempsy> or gunning glue?
[15:30:08] <nubcake> neither
[15:30:23] <nubcake> ^^
[15:30:54] <MacGalempsy> i just poured the lid on my refractory, but came up about 25% sort on the pour
[15:30:55] <nubcake> trying to find my motivation...
[15:31:06] <jdh_> it's over there.
[15:31:12] <MacGalempsy> that was after adding 10%
[15:31:22] <nubcake> lost it somewhere between sunday evening and monday early morning :/
[15:31:29] <nubcake> jdh_ it is?
[15:32:11] <MacGalempsy> maybe not 25% maybe more like 15%
[15:32:15] <nubcake> should be over there too i guess..
[15:35:51] * MacGalempsy gives nubcake some motivation *slapped with a trout*
[15:36:12] <nubcake> :'D
[15:36:48] <nubcake> thanks, but i'm going to head for the bed soon
[15:37:02] <nubcake> alarm rings in 7 hours
[15:37:08] <MacGalempsy> well the cement tamper is almost finished printing
[15:37:10] <sync> nubcake: ölflex is not the proper cable tho
[15:37:20] <sync> igus chainflex is more like it
[15:37:31] <Jymmm> nubcake: sleep when your dead! Now, GET YOUR ASS TO WORK SLAVE!!!
[15:37:45] <nubcake> Jymmm: you kind of sound like my boss ^^

[15:38:32] <nubcake> we always use it, installed in an energy chain (idk the proper term for that)
[15:39:48] <MacGalempsy> Jymmm is kind of like the channel overlord
[15:40:00] <MacGalempsy> next you will start shipping him taxes
[15:40:06] <nubcake> rofl
[15:40:15] <sync> yes nubcake
[15:40:18] <nubcake> seems legit
[15:40:21] <CaptHindsight> Jymmm: do you have a Viking helmet?
[15:40:39] <Jymmm> MacGalempsy: That's Mister Overlord to you!

[15:58:23] <nubcake> night everyone
[16:23:01] <andypugh> An idea for those without a real workshop: https://books.google.co.uk/books?id=1d8DAAAAMBAJ&pg=PA184#v=onepage&q&f=false
[16:24:05] <lowridah> that's thinking outside the box
[16:24:16] <XXCoder> and inside it
[16:28:48] <Jymmm> I'm looking at the tools mounted on the lid... shit, not even one drawer of my tools would fit on that lid! lol
[16:29:16] <MacGalempsy> haha
[16:29:24] <Jymmm> Hell, all my pliers alone wouldn't fit =)
[16:29:29] <MacGalempsy> you have to many tools
[16:29:51] <Jymmm> There is no such thing... right tool for the job.
[16:30:07] <MacGalempsy> cresent, needlenose, channel locks and a flat head and phillips head screw drivers. the rest is junk
[16:30:37] <Deejay> gn8
[16:31:22] <Jymmm> MacGalempsy: This must be your toolbox then... http://image.made-in-china.com/2f0j00mFYQOAIRMboS/39PC-Toolbox-for-Girls-Toolkit-for-Woman-39-PCS-Tool-Set.jpg
[16:31:39] <XXCoder> p9ink used to be male color.
[16:31:40] <MacGalempsy> yessss
[16:31:56] <MacGalempsy> that is called an attache case
[16:32:34] <Jymmm> I'd call it trash.
[16:32:46] <Jymmm> I wouldn't even let a girl own that
[16:34:34] <MacGalempsy> all the pros have attache cases
[16:41:02] <Demure_> So, I bought an Emco F1 mill. Came with a whole bunch of tooling and mounting hardware, but most of it was rusty. No big deal, I soaked 'em in vinegar and dried them afterwards. However, the rust returned after a few days. I went a bit harder and the last three days I've had all parts soak in vinegar, afterwards in a bath of baking soda to stop the acid of the vinegar, scrub them with steel...
[16:41:04] <Demure_> ...wool, drie them immediately and thoroughly and lay them in the oven at 50-60c for a while to evaporate all water left on the surface.
[16:41:19] <Demure_> After taking them out I've scrubbed them once more with steel wool and cleaned them with denatured alcohol.
[16:42:05] <Jymmm> Demure_: spray them with WD-40
[16:42:15] <Demure_> Looks great now, but I'm super worried of the rust returning. I've heard of people coating their stuff in oil or WD40 to prevent this, how neccesary is this? I have no more WD40 available, only olive oil, but I'm now paranoid as hell that if I wait another day to buy stuff I'll be screwed.
[16:42:22] <MacGalempsy> Pics or it didnt happen
[16:42:57] <Jymmm> Demure_: if all you have is olive oil, use it. It can always be wiped off
[16:43:18] <Jymmm> Demure_: got a can of cooking spray?
[16:43:24] <MacGalempsy> vasoline would work too
[16:43:47] <Demure_> No cooking spray. Will go for the olive oil, then.
[16:43:51] <Jymmm> MacGalempsy: a lil much though, and not very good coverage I'd think.
[16:44:01] <Demure_> Should I wipe it off tomorrow and go for WD40 instead?
[16:44:16] <Jymmm> Demure_: You can just pour some olive oil on a rag, then wipe all your tooling with the rang
[16:44:28] <Jymmm> rag*
[16:44:42] <MacGalempsy> demure you are just trying to prohibit oxygen or water from oxidizing the surface
[16:44:57] <Jymmm> Demure_: you in the UK ?
[16:45:25] <Demure_> I see. But once I start using them, I need to wipe them regardless, no? Doesn't seem like a good idea to have any type of oil between the ISO30 toolholder and the spindle.
[16:45:27] <Demure_> No, Netherlands
[16:45:53] <Demure_> http://i.imgur.com/FJhnXRn.jpg
[16:45:55] <MacGalempsy> Demure. how about bicycle chain lubricant, or motor oil
[16:45:56] <Demure_> And a picture as requested. :')
[16:46:08] <Demure_> All the parts resting on the ways, the Z column in the background.
[16:46:13] <Jymmm> Demure_: Not necessarily, but if later on when you use them you can apply the wd40 at that time.
[16:46:14] <Demure_> Nope, none of that available at the moment.
[16:46:27] <Demure_> I can wait a night and get some stuff, but worried they'll rust up overnight mostly.
[16:46:54] <Jymmm> then bring them inside out of the cold humid weather
[16:47:39] <Demure_> Won't be staying outside either way. I do have penetrating oil (Says it also contains MoS2)
[16:47:48] <Jymmm> wrap them in a blanket and serve them hot chocolate too
[16:48:28] <Demure_> They're in front of the TV watching My Little Pony
[16:48:30] <Demure_> I take good care of 'em
[16:48:45] <Jymmm> BRONY parts?!
[16:48:55] <MacGalempsy> Demure_: when will the mill be running?
[16:49:14] <Jymmm> on mini marshmellows in their hot chocolate? YOU EVIL BASTARD
[16:49:17] <Jymmm> no*
[16:49:22] <Demure_> Don't want 'em watching any violence. They'll be cutting through the arts of magic, not through violent forces.
[16:49:32] <Jymmm> hahaha
[16:49:36] <Demure_> I have all the stuff for the controller on the way, so as soon as all is in I can set it up
[16:49:54] <Demure_> All of the ways are cleaned, all of the housing is, just need to build the controller and set it up.
[16:49:57] <Demure_> A month or two at most.
[16:50:05] <Jymmm> Demure_: Keep them in the house, wrap them in a blanket or towel
[16:50:29] <Jymmm> Demure_: the material will absorb the moisture
[16:50:33] <Demure_> The mill will be in the house, too, so they will remain inside forever.
[16:50:39] <Demure_> Good idea on the wraps, didn't think about that.
[16:51:05] <Jymmm> not plastic though =)
[16:51:21] <Jymmm> nice job on the derusting though
[16:51:24] <Demure_> No no, towels. :)
[16:51:28] <Demure_> Eh, I'm a little sad
[16:51:42] <Jymmm> old blanket?
[16:51:44] <Demure_> The black finish on some parts has been completely removed, too.
[16:51:54] <Demure_> Yup, got plenty of those.
[16:52:26] <MacGalempsy> if there is no plastic, you could always let it sit in the oven all night at like 50c
[16:53:00] <Jymmm> 50c ?! not even that =)
[16:53:17] <Demure_> Would olive oil be that bad of a replacement that you'd suggest waiting?
[16:53:42] <MacGalempsy> olive oil should be fine for 1 night
[16:53:59] <MacGalempsy> or you could cake it in peanut butter!
[16:54:07] <Jymmm> Does olive oil go rancide like vegetable oil does?
[16:54:15] <MacGalempsy> in one night?
[16:54:26] <lowridah> yes it goes bad
[16:54:27] <Jymmm> No, in months
[16:54:36] <lowridah> it gets sticky and stinky
[16:55:05] <Jymmm> Demure_: If you have a blanket, and going to keep them in a warm spot, no oil for one night I would think would be fine.
[16:55:39] <Jymmm> I personally would do it
[16:56:00] <Jymmm> but I'm not in NL either
[16:56:39] <Demure_> Ok, good to know. I'll keep 'em warm and blanketed and go out tomorrow morning.
[16:56:57] <Demure_> What would be the best product to get? Just straight forward WD40?
[16:57:03] <MacGalempsy> i would definitely handle the parts with gloves after you clean them
[16:57:16] <Demure_> Damn, that I did not.
[16:57:19] <MacGalempsy> lithium grease
[16:57:26] <Demure_> I guess I wasn't even half as paranoid as I had to be.
[17:00:10] <MacGalempsy> you should be so paranoid that you have already made a had out of aluminum foil
[17:00:37] <Demure_> I guess it'll just have to be a sleepless night. :')
[17:00:49] <Demure_> After handling half of the parts so far after cleaning glove-less.
[17:02:24] <MacGalempsy> the big deal is just keeping the moisture off them. that is why an oven would not be so bad if you are worried
[17:05:58] <Demure_> I would go that route if I trusted my oven, but I'm more afraid the house would burn down if I did that sadly. :')
[17:06:27] <Demure_> Plan will be to wrap them in old hoodies and keep them near the heater.
[17:06:37] <Demure_> I'd use a hot bottle of water but eh
[17:07:18] <JT-Shop> WOW my buddy just got called to the hospital as an alternate for a liver transplant (he has cancer)
[17:07:51] <MacGalempsy> that is great news
[17:08:31] <JT-Shop> yea, worst case he is now top of the list
[17:11:18] <Tom_itx> always like good news.. don't get it that often
[17:17:30] <JT-Shop> they have been battling cancer for about a year
[17:25:07] <lowridah> ironic, i've been battling alcoholism for years and would like a new liver
[17:25:46] <JT-Shop> they won't exchange them if you drink one drop
[17:26:32] <Tom_L> makes sense
[17:26:47] <lowridah> i don't need an excahnge, i'll just take a second one
[17:27:43] <lowridah> like how they leave in the old kidney after a transplant
[17:30:23] <Tom_L> JT-Shop, any luck with that bot file?
[17:31:55] <JT-Shop> yea working on them in the mornings, starting top down and making the index.html files
[17:32:18] <Tom_L> do you want the index files/
[17:32:19] <Tom_L> ?
[17:32:27] <Tom_L> i figured you didn't want those
[17:33:09] <Tom_L> it would be nice if it could read the directory and build it
[17:34:55] <Tom_L> i should go look at it and see what's going on
[17:35:08] <Tom_L> been putting out other fires today
[17:37:08] <JT-Shop> right that's what I'm doing it reads the directory and creates the index.html files for each level
[17:37:23] <JT-Shop> done with the top level now working on the index.html for each channel
[17:37:25] <Tom_L> do you store that in an array?
[17:37:33] <JT-Shop> list
[17:37:52] <Tom_L> i could do it easy in this thing i've been programming in
[17:37:54] <JT-Shop> then sort the list and create the index.html
[17:38:01] <Tom_L> don't know python though
[17:38:07] <Tom_L> right
[17:38:25] <Tom_L> they already write the header to a string
[17:38:28] <JT-Shop> I have a html header, body, footer
[17:38:36] <Tom_L> right
[17:38:37] <JT-Shop> changed that a bit
[17:38:58] <Tom_L> which part?
[17:38:58] <JT-Shop> I replace a marker for each level
[17:39:06] <JT-Shop> all of it lol
[17:39:09] <Tom_L> heh
[17:40:15] <JT-Shop> doing a systematic walk through of the code from scratch, easier for me to use current ways to do things in python
[17:41:28] <BeachBumPete> evening all
[17:41:37] <JT-Shop> wood crib's a bit over 5/8's full looking good
[17:41:44] <Tom_L> where does it read the directory currently?
[17:41:46] <Tom_L> or does it?
[17:42:14] <JT-Shop> the os. stuff is what reads in the directories
[17:42:39] <JT-Shop> it's down in the beer cave and I'm out in the shop
[17:43:16] <Tom_L> i see some of it but it makes no sense to me
[17:43:28] <Tom_L> wtf is os.walk()?
[17:44:06] <JT-Shop> it walks down the directories and files
[17:44:58] <Tom_L> it looks like he had intentions of doing that but didn't finish
[17:45:22] <Tom_L> #TODO: Create folders
[17:46:15] <JT-Shop> I'm thinking of creating a directory for each year and making navigation a bit easier
[17:47:07] <Tom_L> current year and previous would be enough really
[17:48:09] <Tom_L> slick part would be to transfer them over at year end and update all the indexes
[17:48:11] <Tom_L> :)
[17:52:14] <JT-Shop> yup
[17:52:23] <JT-Shop> working on being cool
[18:19:19] <Crom> bbiaw
[18:24:25] <Crom> so for a voltage divider to convert the 0-10v to a 0-5v for the arduino nano
[18:24:52] <Crom> 2 2k resistors? or 2 1mohm resistors
[18:25:40] <jdh_> yes
[18:27:02] <Crom> hmm 10k 10k
[18:27:18] <jdh> 4.7/4.7
[18:28:50] <Crom> hmm 4.7k is 1ma
[18:29:55] <Crom> 2k 2k is 2.5ma
[18:30:27] <Crom> 5ma max... into A0
[18:31:00] <jdh> 2.2k
[18:31:33] <Crom> hmm .02watts
[18:31:45] <Crom> hmm .04watts
[18:36:13] <Crom> 4 10k resistors in parallel then 4 10k in parallel so 2.5k
[18:36:48] <Crom> didn't want to solder 900 2.7ohms together
[18:42:25] <Crom> err 27ohm in series 81 times
[18:49:32] <Crom> hmmm 100k's 410ohms 10k pot 50k pot 10k pot 22k pot and more of the 10k's hmmm thinking of the little 10k pot... with a 10k resistor in parallel... then I get 0 to 5k trim.... so 0v-6.67v
[18:55:20] <Crom> Tomorrow I've be checking the 0-10v to see if it works on the bob. put 5kohm between between the terminals and mesure voltages
[18:58:58] <Crom> found 2 hose clamps to start making the hall effect sensor mount... i may be up and running tomorrow night
[19:23:10] <MacGalempsy> witnit: whats going on?
[20:22:51] <Jymmm> what are ppl using for foundary cement? on the cheap
[20:32:37] <enleth> raw grog clay, it's not expensive
[20:34:04] <enleth> and you can extract pre-made bricks from old tile stoves
[20:35:05] <Jymmm> grog is fine mesh, whats the binder?
[20:36:56] <enleth> raw unfired clay, which is then fired in situ, binding the grog
[20:37:30] <enleth> there doesn't have to be much of it to work
[20:37:34] <Crom> lots of perlite
[20:38:00] <Jymmm> Crom: I was looking at this and the comments... https://www.youtube.com/watch?v=ZZAoohv4ku8
[20:39:19] <enleth> Jymmm: it all really depends on what temperatures you need
[20:39:49] <Jymmm> enleth: lining a 55gal barrel stove (basically)
[20:39:54] <enleth> using cement and/or water glass is fine up to 950-1050C or so
[20:39:56] <CaptHindsight> 4000C
[20:40:38] <enleth> for 1500C to melr iron - you're looking at a pure ceramic build with fire bricks and joined by fired, not set binder
[20:40:44] <enleth> *melt
[20:41:22] <CaptHindsight> Jymmm: yah meltin or heatin?
[20:41:40] <Jymmm> Basically I'm looking to make custome firebrick to line a wood stove for heating
[20:42:33] <Jymmm> CaptHindsight: Lining one of these (top half) http://www.raksystems.com/52btab.jpg
[20:42:52] <enleth> so the old way is grog with some raw clay, fired to harden it. you get an old-fashioned brick.
[20:43:30] <enleth> the modern way... no idea really, haven't tried to make bricks from scratch the modern way
[20:43:36] <jdh> ar you preparing for the trumpacolypse?
[20:44:58] <Jymmm> jdh: Close, the NoMoreFreezingJymmmsAssOffInTheGarageThisWinterOlypse
[20:46:32] <BeachBumPete> Damn my leveling studs are kinda rusty and the big lock nuts on them are sorta frozen on them. Got them soaking in PB blaster so I can get the VMC on its pods hopefully tonight so I can start getting it powered up.
[20:48:13] <CaptHindsight> Jymmm: how cold does it get there?
[20:48:30] <Jymmm> CaptHindsight: High twenty's
[20:48:55] <Jymmm> CaptHindsight: and the garage is unfinished, uninsulated
[20:52:32] <BeachBumPete> got a new request for a product today from a former customer, its for a new rifle they just started making that looks pretty cool. Hopefully I can design something interesting for it ;)
[21:06:02] <Jymmm> This are perlite maybe? http://www.homedepot.com/p/Hercules-1-2-gal-Furnace-Stove-Cement-35515/202078154
[21:07:22] <CaptHindsight> Kaolin Nepheline Syenite Sodium silicate Mica Wollastonite Crystalline silica (Quartz)
[21:07:55] <Jymmm> CaptHindsight: is that english you are speaking?
[21:08:09] <CaptHindsight> da da
[21:08:31] <Crom> We usually just go to the garden center and get a bag of perlite
[21:08:57] <Jymmm> perlit is the easy part, I'm not sure what to bind it with
[21:09:37] <Jymmm> all kinds of "mortars" http://www.homedepot.com/b/Building-Materials-Concrete-Cement-Masonry-Mortar-Cement-Concrete-Mix/Mortar/
[21:09:46] <Jymmm> bah
[21:10:24] <Jymmm> http://www.homedepot.com/b/Building-Materials-Concrete-Cement-Masonry-Mortar-Cement-Concrete-Mix/Mortar/N-5yc1vZbogdZ1z0u18h

[21:12:11] <Jymmm> Crom thank you, evne found that cheper https://www.amazon.com/IMPERIAL-MANUFACTURING-Cement-Refactory-Buff/dp/B0149J01HY
[21:12:55] <Crom> nice
[21:14:23] <CaptHindsight> Jymmm: don't blow yourself up real good
[21:14:44] <Jymmm> CaptHindsight: How would I do that?
[21:15:20] <Jymmm> CaptHindsight: al the pyrotechnics are in magazines
[21:16:37] <CaptHindsight> Popular Bomb Making, Homes and Bombs, Bombs Monthly
[21:17:12] <Crom> Poormans James Bond, and paladin press CIA improvised Munitions...
[21:17:26] <Jymmm> CaptHindsight: http://www.securallproducts.com/explosive_material_storage_magazine.asp
[21:20:21] <CaptHindsight> oh the metal box kind
[21:20:47] <Jymmm> CaptHindsight: More like the ATF approved kind =)
[21:21:19] <Jymmm> Ok, found this in the comments: "It really isn't an exact formula. It is, basically, a 50/50 mix of type S mortar mix and perlite with enough water added to make a stiff mortar of uniform consistency. "
[21:21:58] <Jymmm> http://www.homedepot.com/p/SAKRETE-80-lb-Type-S-Masonry-Mortar-100033433/100598898
[21:23:59] <Jymmm> where to get bulk perlite or Vermiculite ?
[21:24:41] <Crom> garden center
[21:25:12] <Jymmm> Ok, will try that if there are any aorund.
[21:25:14] <Crom> 2 CUFT bags
[21:25:47] <Crom> gardeners love it since it holds water
[21:26:14] <Jymmm> HOLDS water? I thought it allows to drian water
[21:26:19] <Jymmm> drain*
[21:26:43] <Crom> it's porus
[21:26:59] <Jymmm> I have soem perlite, but it's a small bag
[21:27:07] <Crom> like pumice... it holds water as well as aeriates
[21:27:40] <Jymmm> $17 for 2cf seems a bit pricy
[21:27:40] <Crom> that's why it's used in refractories... it's hollow rock so a good insulator
[21:28:34] <Jymmm> Eh, if it does the job making this ghetto wood stove, I'll be very happy
[21:29:55] <Crom> hmmmm http://boltontool.com/Lathes/cnc-machine/m4a-3-axis-cnc-mill
[21:36:55] <Crom> ok going home...
[21:36:59] <Crom> laterzz
[21:44:47] <enleth> Jymmm: what about insulating the garage as well?
[21:48:36] <Jymmm> enleth: I'm working on insulating the ceiling, but that might be a month or so.
[21:49:14] <Tom_L> Jymmm, rue tried homebrew stuff but i don't think it worked out well for him
[21:49:50] <Jymmm> Tom_L: home brew... firebrick? or stoves? or boilers? or ???
[21:50:17] <Tom_L> firebrick & mortar
[21:52:15] <Jymmm> Tom_L: Ah, well if this lasts a season, I'm good with it. It's not the "ultimate" solution, just seeing how it does.
[21:52:39] <Tom_L> http://ruemohr.org/~ircjunk/projects/heatplant/dscn0581.jpg
[21:53:05] <Jymmm> Tom_L: it's round, thats all I can tell from the photo
[21:53:21] <Tom_L> yeah i was looking for his molten rocks from the bottom of it
[21:53:29] <Tom_L> must not be online anymore
[21:53:35] <Jymmm> ah
[21:54:26] <Jymmm> Tom_L: What's kinda funny is that Webber bbq's take the heat all the time, but have no bricks at all
[21:54:52] <Tom_L> they have a bottom grate
[21:55:10] <Tom_L> cool air is brought in from below too
[21:55:38] <Tom_L> http://ruemohr.org/~ircjunk/projects/heatplant/dscn9668_heatplant.jpg
[21:55:42] <Jymmm> the bottom grate is MUCh cheaper than the hettle itself, I melted one =)
[21:55:45] <Tom_L> one of his early attempts
[21:57:14] <Tom_L> http://ruemohr.org/~ircjunk/projects/heatplant/dscn0131.jpg
[21:57:14] <Jymmm> it looks like wood ash to me
[21:57:35] <Tom_L> http://ruemohr.org/~ircjunk/projects/heatplant/dscn0132.jpg
[21:57:37] <Jymmm> Tom_L: did he overfire it?
[21:57:47] <Tom_L> it was hot
[21:58:05] <Jymmm> so is my hot sauce
[21:58:47] <Jymmm> Tom_L: I'm not trying to be rude or anything, but photos alone are not too helpful without specifics.
[21:58:47] <Tom_L> http://ruemohr.org/~ircjunk/projects/heatplant/dscn0134.jpg
[21:58:55] <Tom_L> kinda cool really
[21:59:05] <Tom_L> he's got lots there
[21:59:12] <Tom_L> you should look at the folder
[21:59:43] <Jymmm> Yeah I have, but without comments/context, not really helpful
[21:59:53] <Tom_L> so ask him
[22:00:14] <Tom_L> he's been at this for 2-3 yrs testing things
[22:01:03] <Tom_L> had pumps freeze on him one winter
[22:01:19] <Jymmm> I try, but it doens't seem like he's all that interested in talking about it. and conversations start good, but kinda drift off and then I get lost.
[22:01:31] <Tom_L> that's just rue
[22:02:02] <Jymmm> Tom_L: heh
[22:02:29] <Tom_L> doesn't have time to do what he wants so has been spending less time talking about it
[22:02:35] <Tom_L> doing more talking less
[22:02:46] <Jymmm> ah gotcha, I can understand that.
[22:03:01] <Tom_L> he's up by vancouver
[22:03:05] <Tom_L> area
[22:04:46] <Jymmm> Oh, I didn't realize vancover got THAT cold.
[22:05:05] <Tom_L> across the pond from it to the north
[22:05:14] <Tom_L> i think
[22:05:58] <Tom_L> http://ruemohr.org/~ircjunk/projects/smelter/
[22:06:07] <Tom_L> another heat related project
[22:07:33] <Jymmm> Teh LAST thing I need to do is melt metals TYVM =)
[22:11:06] <MacGalempsy> poured the lid for the refractory. https://flic.kr/p/Nu8R97
[22:11:28] <Tom_L> nice
[22:11:45] <MacGalempsy> grog and kaolin are the best components
[22:13:05] <MacGalempsy> there is a paper that shows 50/50 grog 80mesh to dust/kaolin
[22:13:47] <MacGalempsy> is the best to decrease porosity after firing
[22:13:52] <Tom_L> he's actually closer to Gibsons
[22:16:31] <MacGalempsy> tomorrow ill pour the middle and top sections then let it cure at 65c for 24hs, then to 150c for another 3 days
[22:21:14] <BeachBumPete> you gotta video your first pour :)
[22:29:22] <Crom> ugh... upgrades are gonna be really slow... my wife told me her account is down to $750... So All the bill are coming out of my accounts for the forseeable future...
[22:29:43] <Crom> no ebay :(
[22:33:03] <Crom> at least I got my transfer punches... !-Z and 1/16 to 1/2"
[22:33:10] <Crom> A-Z
[22:33:47] <BeachBumPete> gotta love transfer punches...I have a bad habit of using them for steel shafts from time to time tho lol
[22:33:59] <Crom> that too
[22:34:18] <BeachBumPete> I think I am missing a couple now I need a new set
[22:34:52] <Crom> I could really use the 1-80 set....
[22:35:18] <Crom> I think that has one really close to 0.156"
[22:35:26] <BeachBumPete> I would like to have a set of those female thread transfer punches
[22:36:04] <Crom> female?!?!
[22:36:22] <Crom> don't you mean the male which go in the threaded hole
[22:36:33] <BeachBumPete> yeah that one hehe
[22:36:49] <Crom> one of these days...
[22:36:49] <BeachBumPete> meaning they go into a female threaded hole LOL
[22:38:36] <BeachBumPete> well I managed to get the VMC up on the pods tonight...just gotta finish leveling it up tomorrow after work.
[22:38:55] <Crom> full set of those would be some bucks.. 10-32, 1/4,5/16,3/8,7/16,1/2,9/16, 3,4,5,6,7,8,10,12,14mm fine and course and a couple of mediums in metric as well
[22:39:08] <BeachBumPete> I found the steel bracket for the cable chain last night it was sitting in the lathe bed where I put a lot of the stuff I removed.
[22:46:53] <BeachBumPete> I wonder if I can make some of those on the CNC lathe once it is working
[23:49:59] <Jymmm> http://myheap.com/casting-molding/my-heap-mold-book/chapter-1-materials/how-to-make-irc.html
