[00:45:20] <Wolf_> heh, trying to find useful info on linuxcnc + mesa boards is fun, youtube is of little help it seems...
[00:56:56] <CaptHindsight> Wolf_: what specific info?
[00:57:31] <Wolf_> step one, figure out what exactly I need
[00:58:00] <CaptHindsight> post a list of what you wish to control
[00:58:13] <CaptHindsight> number of steppers, servos, IO etc
[00:59:13] <Wolf_> probably 3x BE25A20 servo drives (+10/-10v ref controlled) and probably a VFD
[00:59:20] <CaptHindsight> do you want to use PCI, PCIe or Ethernet?
[00:59:53] <Wolf_> that I’m open on, going to build a computer to go with it
[01:00:19] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&product_id=120
[01:00:37] <CaptHindsight> 7i77 is the servo board
[01:02:12] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=58 6i25 is a PCIe FPGA card to control it
[01:02:23] <Wolf_> oh, the 7i77 handles the encoder outputs? so I don’t really need a servo amp with encoder inputs?
[01:02:47] <CaptHindsight> yeah, so you can use just a servo amp
[01:03:09] <CaptHindsight> they also make a servo amp
[01:03:16] <Wolf_> well, thats nice to know, good thing I only have 1 of each right now lol
[01:03:56] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=65&product_id=149
[01:03:58] <Wolf_> B25A20 amp and a BE25A20, both are 190V dc max 25A drivers
[01:04:43] <Wolf_> ouch, I’ll stick to those two ^ lol
[01:05:10] <Wolf_> I can find the B25A20 with built in power for ~$80 on eBay
[01:05:12] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=306 7i92 for the FPGA over Ethernet
[01:07:51] <CaptHindsight> LinuxCNC Supported Boards
http://store.mesanet.com/index.php?route=product/category&path=83
[01:07:55] <Wolf_> so that 7i92 + 7i77 and a computer
[01:08:05] <CaptHindsight> yeah
[01:08:25] <CaptHindsight> plus a field power supply for the machine side IO
[01:10:04] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=83_86&product_id=74 7i33 is a quad servo board, to save some $$
[01:11:14] <CaptHindsight> you have to decide on headers with ribbon cable vs printer cable and connectors
[01:11:44] <Wolf_> well, ethernet + headers, mount all the crap at the machine
[01:13:05] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=83_85&product_id=303 7i92H with headers
[01:14:45] <Wolf_> and instock :D lol
[01:16:00] <CaptHindsight> they sell kits with all the cables so you know everything matches
[01:19:38] <Wolf_> yeah, that combo seems to have plug issues, 7i92H is 2x 26 pin, the 7i33TA is 50 pin
[01:20:20] <CaptHindsight> call or email them with what you want to do and they will give you all the matching part numbers
[01:23:41] <Wolf_> There are currently six 7I92H compatible breakout cards available from Mesa, the 7I74 through 7I78 and 7I85 < that explains part of the problem lol
[01:28:46] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=62&limit=75 7i80 ethernet with 50 pin headers
[01:30:48] <CaptHindsight> ask in 6-8 hours
[01:30:58] <CaptHindsight> JT also stocks and sells Mesa
[01:31:40] <Wolf_> yeah, I know a few people in here are familiar with them
[01:32:35] <CaptHindsight> bbl
[01:33:25] <CaptHindsight> I have a bunch but I don't keep track of the part numbers
[01:33:32] <Wolf_> lol
[01:33:56] <Wolf_> yeah, once in service not much need to mess with them right?
[02:21:38] <Deejay> moin
[02:22:04] <Wolf_> morning
[02:22:15] <Wolf_> and this is how I know I’m up way too late lol
[05:24:25] <XXCoder> wow!
https://www.youtube.com/watch?v=b6ME88nMnYE
[05:43:11] <jthornton> morning
[05:43:20] <XXCoder> hey jt
[05:43:24] <XXCoder> did you see link above
[05:43:50] <jthornton> not yet
[05:44:13] <XXCoder> its amazing really
[05:46:00] <Tom_L> morning
[05:46:13] <XXCoder> yo
[05:47:54] <jthornton> hey
[06:00:18] <jthornton> looks like a little cool weather is on the way
[06:00:45] <XXCoder> man where ya
[06:00:50] <XXCoder> its been cold here for while lol
[06:11:37] <archivist> 7.2 deg c in my bedroom this morning
[06:12:54] <XXCoder> 21 here
[06:12:57] <XXCoder> 21c
[06:13:00] <XXCoder> 7.2 jeez
[06:19:29] <jthornton> 10c here
[06:28:13] <_methods> 27c here heheheh
[06:28:32] <XXCoder> anyone bidding for 30c? 30c 30c
[06:28:53] <XXCoder> 28c? 28c?
[06:29:07] <XXCoder> _methods final bid at 27c winner!
[07:35:32] <jdh> nice
[07:36:34] <jdh> 24c today
[07:38:25] <_methods> lovin it
[07:38:41] <_methods> if this is what global warming is all about, i'll take some more
[07:45:49] <Tom_L> 4.4c
[07:50:09] <_methods> sounds like you need a little global warming
[08:49:29] <sigi_> Hallo würde eine info zu gmoccapy brauchen kann mir da einer helfen
[09:52:55] <kanzure> CaptHindsight: i've put a lot of thought into the DNA assembly problem, and i think i have an interesting (although experimental) solution. this is compatible with inkjet printing of small oligos.
https://groups.google.com/d/msg/enzymaticsynthesis/uyZqtJO24RE/lApLb4JmCAAJ
[09:54:00] <CaptHindsight> kanzure: I'll take a peek in a bit
[09:54:08] <kanzure> yep whatevs, no rush
[09:55:30] <kanzure> short version is: do directed evolution of "homologous recombination" cell strains, which at the moment can assemble a few DNA fragments into a longer strand, and through selection it will be possible to make them assemble 1e5 (or more) different DNA fragments at a time.
[09:56:01] <kanzure> so the input to this system is literally "all the inkjet-printed DNA fragments, in a giant single pot/reaction/batch"
[10:00:46] <FinboySlick> Is ISO40 the same as cat40?
[10:01:00] <Wolf_> no/yes
[10:01:45] <Wolf_> taper is the same, drawbar/tail of it is different
[10:02:00] <FinboySlick> OK. What about bt40?
[10:02:07] <FinboySlick> Yet another different one?
[10:02:17] <FinboySlick> (with the same taper)
[10:02:52] <Wolf_> idk, I only looked at iso40 vs cat40 (by googling and looking at prints of each)
[10:03:06] <archivist> or the front is different for the toolchanger
[10:03:38] <Wolf_> ^ that to, V grove in cat40/50 for tool changer
[10:03:40] <archivist> and the dogs vary a little
[10:05:03] <FinboySlick> Hmmm. That schaublin wants iso :P I don't think the toolchanger bit matters there.
[10:05:14] <Wolf_> lol
[10:06:39] <FinboySlick> Wolf_: You laughing because I'm still mildly obsessing over that little monster?
[10:06:46] <Wolf_> similar reason is why I found out, NMTB40/50 machine I’m looking at
[10:09:00] <Wolf_> which totally baffled me that the guy who owns the machine didn’t know that cat40/50 would fit seeing that he owned a CNC shop with a couple VMCs…
[10:09:59] <FinboySlick> Wolf_: Hmmm... So essentially, if we're talking about a manual screw-in drawbar, it wouldn't really matter if I got BT40 instead of iso40?
[10:10:22] <archivist> so more than one drawbar
[10:10:44] <Wolf_> look up BT40, find a print, print it, or you might find all the 40’s on one page
[10:11:14] <Wolf_> faster to look at the prints then trying to explain it
[10:11:28] <FinboySlick> archivist: Well, since it comes with zero tooling, I can still have just one drawbar if I always buy the same type.
[10:11:34] <archivist> http://www.tools-n-gizmos.com/specs/Tapers.html
[10:12:12] <archivist> a page to keep in your bookmarks
[10:12:38] <Wolf_> ^ I think thats the same page I used :D
[10:13:04] <Wolf_> Brown & Sharpe Taper <grrr
[10:13:37] <Wolf_> I would have that van norman in my shop if it wasn’t for that odd damn spindle
[10:14:12] <archivist> I have a BS taper to their equally silly solide taper endmill design
[10:14:57] <gregcnc> CAT will have fractional pull stud threads, ISO or BT are metric
[10:16:19] <archivist> my horizontal has an odd in between size cat35 as far as I can tell
[10:16:47] <Wolf_> NMTB are inch thread
[10:16:54] <gregcnc> there are a few bt35 machine out there
[10:17:10] <Wolf_> but I think the drawbar length won’t be right
[10:17:32] <archivist> mine is circa 1942 long before metric bt taper
[10:18:17] <gregcnc> NMTB have the extended tail on the taper
[10:21:11] <Wolf_> hmm
http://i.imgur.com/tiB9E3O.jpg I might be wrong on the B&S
[10:22:41] <Wolf_> Hardinge 50V
http://shophardinge.com/productGrid.aspx?catID=1629 that what it was lol
[10:22:47] <archivist> BS 2A milling machine had a camlock on a 30 taper
[10:23:12] <Wolf_> and the reason I didn’t pick up a $500 monster of a mill...
[10:24:06] <archivist> idiots at
http://shophardinge.com/productGrid.aspx?catID=1629 redirect me to a dead domain
[10:24:19] <archivist> http://uk.shophardinge.com/cgi-sys/defaultwebpage.cgi
[10:24:20] <FinboySlick> P25 is even harder to find.
[10:24:24] <Wolf_> lol
[10:25:02] <Wolf_> nice, site was giving me $254 usd each for 50V collets
[10:25:26] <Wolf_> not missing much archivist
[10:26:34] <gregcnc> only a few 50V on ebauy
[10:27:48] <Wolf_> yeah, when I looked at the machine I think I could only find 1/2” collets in the under $254 range…
[10:34:05] <Wolf_> ok, mesa question, 7i33 won’t work with a 7i92 will it?
[10:34:33] <pcw_home> not without a lot of funny wiring
[10:35:35] <Wolf_> ok, looks like either 7i80HP + 7i33TA or 7i92M + 7i77 are my best choices
[10:38:55] <Wolf_> any suggestions? though the 7i77 makes more sense for possible 4th axis on a mill
[10:40:32] <pcw_home> 7I77 has a lot of I/O also
[10:40:53] <Wolf_> yeah, I may have overlooked that need lol
[10:43:29] <Wolf_> now the 7i92, does that need a direct ethernet port off the linux box or will it work hooked to the same dumb switch as the linux machine?
[10:43:50] <JT-Shop> it must be hooked to the onboard Ethernet port on the MB
[10:44:08] <Wolf_> ok
[10:44:29] <JT-Shop> http://www.mesaus.com/info/links.html
[10:47:30] <pcw_home> plug in Ethernet cards work also (RTK and Intel)
[10:47:43] <Wolf_> ok cool
[10:50:18] <Wolf_> oo, nice, link for power supply :D
[10:51:21] <pcw_home> You _might_ get away with mixed traffic if you limited the normal internet traffic bandwidth/MTU but its disallowed currently
[10:51:50] <Wolf_> yeah, on actual machine I won’t take the risk
[10:53:34] <Wolf_> and usb>ethernet should work fine for network access
[10:54:54] <Wolf_> ouch, $227 for a power supply… and still not sure what voltage I need
[11:00:38] <pcw_home> thats what I have on my test machines, MB Ethernet for real time and 1G USB --> Ethernet dongle for network
[11:01:02] <Jymmm> why usb?
[11:01:14] <JT-Shop> www.antekinc.com
[11:01:15] <Wolf_> my guess is cheap/easy
[11:01:18] <JT-Shop> power supplies
[11:01:34] <Wolf_> JT-Shop: yeah thats where I was looking
[11:01:52] <Jymmm> wyy not pci, etc?
[11:03:07] <pcw_home> Most of my test machines are USFF so no slots
[11:03:38] <Jymmm> ah
[11:04:10] <Jymmm> and no minipci slots?
[11:04:11] <pcw_home> but PCI/PCIE work fine for RT also as long as they are not Broadcom/Atheros/Marvell
[11:06:10] <Jymmm> When it comes to ethernet, I've always seen usb to be like dropping a geo metro engine into a corvette
[11:06:36] <jdh> usb3 is speedy
[11:07:08] <pcw_home> USB3 is more like PCIE electrically
[11:07:08] <Wolf_> for a CNC control computer, IMO you really don’t need crazy bandwidth for internet/network
[11:07:24] <Jymmm> jdh: 10GigE ?
[11:07:56] <jdh> you have nothing that can take advantage of that
[11:08:09] <Jymmm> pcw_home: Well, the USB part (polling) has always been the issue, bot the usb bandwidth
[11:08:26] <Jymmm> jdh: 10 port fiber switch
[11:08:53] <Wolf_> really, are you going to even break needing 100 on a machine thats driving a mill/lathe or something
[11:08:55] <jdh> realistic use case for this context?
[11:09:10] <Jymmm> rendering
[11:09:31] <jdh> on a cnc controller
[11:09:59] <Jymmm> I never said cnc
[11:10:27] <Jymmm> I'm just not fond of usb
[11:10:28] <Wolf_> everyone else is talking about cnc controller use case :P
[11:10:53] <Jymmm> No, I inquired about usage of usb ethernet
[11:11:36] <Jymmm> and USFF was one reason given
[11:22:07] <svendev_> Hello i am new her, hope for a little help?
[11:22:34] <cradek> hi, always just go ahead and ask questions, no need to ask first
[11:22:46] <cradek> and welcome
[11:24:39] <Jymmm> jdh: In the case of mechanical cnc, no, not an issue. butif it was something lke a galvo laser, it might need consideration.
[11:24:58] <Jymmm> pcw_home: What ethernet chipset is the mesa card using?
[11:25:21] <pcw_home> Micrel KSZ8851
[11:25:55] <pcw_home> (Well its MicroChip now, Micrel was acquired)
[11:26:11] <svendev_> Where do i find the newest Debian Distribution for linux-cnc
[11:26:24] <Jymmm> pcw_home: Ah, why not intel?
[11:26:53] <cradek> svendev_: at the top of linuxcnc.org there is a Download link
[11:29:01] <ktchk> Hi any one controlling robot ??
[11:35:12] <svendev_> thank you, I will try
[11:35:32] <CaptHindsight> ktchk: Cartesian, SCARA, delta, etc. ?
[11:35:40] <_methods> robots are so unruly
[11:35:45] <_methods> very hard to control
[11:35:53] <CaptHindsight> eat old people medicines
[11:36:09] <_methods> sassy robots are the worst
[11:36:28] <CaptHindsight> how about the ones that never leave?
[11:36:44] <Wolf_> mine mows my lawn…
[11:36:49] <CaptHindsight> party is over, you're cleaning up and yawning...
[11:42:44] <pcw_home> Jymmm: the Ethernet chip on the Mesa card interfaces to the FPGA so its a chip with a simple interface (not PCI/PCIE)
[11:42:46] <pcw_home> Intel only makes PCIE (or integrated in chipset) Ethenet chips
[11:43:25] <Jymmm> pcw_home: Ah, I thought it might be something like that, I noticed iteven has SPI interface too, which is kinda neat
[11:43:51] <pcw_home> Were not using the SPI one however
[11:44:00] <pcw_home> (too slow)
[11:44:01] <Jymmm> small buffer, but eh
[11:44:28] <pcw_home> in this case bigger is not better
[11:44:57] <Jymmm> For RT you mean?
[11:45:31] <pcw_home> yes
[11:45:50] <Jymmm> ok, I can see that.
[11:49:40] <pcw_home> The buffering does work (I could access the card with mesaflash while running linuxcnc, before that was disallowed in the driver)
[11:49:42] <pcw_home> but normally the system is strictly synchronous when running in RT mode so there's only 1 RX and 1 TX packet buffer in use
[11:51:47] <Jymmm> pcw_home: Nice!
[12:22:42] <IchGucksLive> hi
[12:25:54] <IchGucksLive> the 5-axis styro did the whole dayx-mas cuttings
[12:34:46] <Jymmm> IchGucksLive: you have a 5 axis styro cutter? pics?
[12:35:32] <IchGucksLive> im not alowed to post pics on this its a University owned mashine
[12:35:43] <IchGucksLive> the animation is on the youtube channel
[12:36:18] <IchGucksLive> https://www.youtube.com/watch?v=AoZWKBE86g0#
[12:36:49] <IchGucksLive> there is also a Rotation Axis inside the table
[12:38:58] <IchGucksLive> Jymmm: let me upload a real vid from the 5th axis only that has no mashine on it
[12:42:59] <IchGucksLive> Jymmm:
https://youtu.be/O-GNnhIljF4
[12:45:03] <IchGucksLive> its only some drills in PMMA and fits 55.6 Steps per Deg

[12:52:14] <IchGucksLive> 50:1 gear
[13:21:35] <IchGucksLive> hi pcw
[13:31:45] <pcw_home> I'm not really coming and going, 'tis just flaky ATT Internet at work
[13:33:06] <IchGucksLive> Telekom in germany is also a crap
[13:33:12] <IchGucksLive> im offf Gn8
[14:06:13] <reox> Hi! I just wanted to ask if the maintaines of the debian repo are aware, that in version 1.4 of apt the SHA1 hashes are untrusted and accessing linuxcnc repo will not work anymore... Are there any plans to change the signature for the repo?
[14:09:30] <reox> You will get this error message, if you try to update: W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error:
http://linuxcnc.org jessie Release: The following signatures were invalid: EEDD0D29F81DCAA0D258661F3CB9FD148F374FEF
[14:12:35] <cradek> reox: thanks! if you have a github account, could you open a bug report about this? it'll help us get it solved for the next release cycle. it would especially help if you know the fix.
[14:13:37] <reox> cradek: sure!
[14:14:24] <cradek> awesome, thank you
[14:17:45] <reox> cradek: I think this should fix it
https://wiki.debian.org/Teams/Apt/Sha1Removal but I do not run a repo myself, so I'm just guessing ;)
[14:18:25] <cradek> are you seeing the "No hash entry found ... which is strong enough for security purposes" message?
[14:18:56] <reox> mh no actually i think this is something else... because in the Release file there are sha256 and 512 hashes. The problem is, that Release.gpg's hash is SHA1
[14:19:25] <cradek> hm
[14:19:52] <cradek> I bet whatever information you can add to the bug report will help
[14:20:01] <cradek> (I'm not the one to fix this)
[14:24:20] <reox> sure, i think this is somehwhat more related:
https://debian-administration.org/users/dkg/weblog/48 So as far as i remember, the Release.gpg is just the sign of Release with your key. so settings this should help IMO... I'll add this to the ticket!
[14:36:41] <reox> cradek: i just opened the ticket, HTH! cu!
[14:37:33] <cradek> cheers, surprise helpful internet person
[14:38:18] <reox> hehe, actually linuxcnc user - thats how i found that out (using the simulator on my workstation)
[14:38:30] <cradek> :-)
[14:57:58] <svendev_> cradek: up and running, thank you
[15:02:00] <cradek> yay!
[16:24:00] <kyle____> hey guys
[16:24:05] <kyle____> want a good laugh?
[16:24:25] <kyle____> http://sfbay.craigslist.org/sfc/hvo/5889711746.html
[16:24:31] <kyle____> "parts alone are worth asking price"
[16:24:50] <kyle____> it's a HF x2 with steppers...
[16:25:20] <XXCoder> 3jk lol
[16:25:29] <XXCoder> even if frame is included just nagh
[16:26:03] <pcw_mesa> Its worth it for the snazzy green motors alone
[16:26:05] <kyle____> it's so tempting to email him and ask if it comes with the operator
[16:26:15] <kyle____> but i won't be antagonistic
[16:26:43] <kyle____> snazzy green motors, you say? i'll brb, you buying?
[16:27:15] <JT-Shop> what's up XXCoder
[16:27:25] <XXCoder> getting ready to go work
[16:27:39] <JT-Shop> I'm just knocking off
[16:27:59] <kyle____> how much holding torque is good for an X2 anyway?
[16:28:06] <kyle____> 200 oz-in or so?
[16:28:54] <andypugh> He probably has spent that much and more on it.
[16:30:09] <JT-Shop> holding torque is how hard a stepper will resist being turned...
[16:38:11] <sector_0> what kind of rails do you guys use for cnc mills?
[16:38:18] <sector_0> belt drive, screw, etc
[16:40:24] <JT-Shop> linear rails and ball screws
[16:45:21] <JT-Shop> kyle__1:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
[16:45:29] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Motor_Speed_Limitations
[16:45:40] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mechanical_Spreadsheet
[16:45:54] <sector_0> JT-Shop, is there a particular reason for using ball screws?
[16:46:01] <sector_0> I've seen most CNC have those
[16:46:09] <sector_0> is it because of rigidity?
[16:46:36] <sync> accuracy and no backlash
[16:48:22] <bpuk> and efficiency
[16:49:51] <sector_0> oh ok
[16:50:40] <JT-Shop> what they said
[16:54:19] <bpuk> I personally really like using hydrostatic bearings for the table - but it's not something I'd recommend to most people
[16:56:53] <Deejay> gn8
[16:58:51] <bpuk> low friction, high stiffness. downside is the need to use a pump to pressurise them
[17:00:05] <Tom_L> used on measuring equipment typically i think
[17:00:27] <Tom_L> cmm etc
[17:00:51] <bpuk> CMM are usually air bearings, yup
[17:01:07] <bpuk> but you also see them used ocassionally on high speed or high load stuff
[17:01:23] <sync> internally preloaded air bearings are nice
[17:05:44] <bpuk> my (WIP) mini-mill will be using fluid V bearings. aiming for short travel, high accel.
[17:34:54] <SpeedEvil> http://i.imgur.com/fwnXV.jpg I want _all_ the axes.
[17:35:59] <kyle____> JT-Shop, thanks, been looking for a resource like this
[17:36:21] <SpeedEvil> (from
http://imgur.com/gallery/SVJlt)
[17:36:23] <kyle____> sometimes it gets really confusing to try to work through it intuitively
[17:37:25] <JT-Shop> yea it is a great help
[17:37:58] <Frank_6> hi ppl
[17:41:08] <JT-Shop> Yo Frank
[17:44:39] <bpuk> eyup Frank
[17:44:49] <bpuk> hows the machine looking?
[17:53:43] <Frank_6> there she is, im gathering the last few components!
[17:54:05] <bpuk> are you going to have pictures or a build thread soon?
[17:54:15] <Frank_6> so yeah, the most exciting and anxious part of the build
[17:54:54] <Frank_6> i started a build thread but didnt updated it, only posted a few pics of an old cad design
[17:55:03] <Frank_6> give me a sec ill give you a few pics
[17:57:27] <Frank_6> http://imgur.com/v6IP4KL
[17:59:36] <JT-Shop> remind me what your building
[17:59:40] <JT-Shop> nice work btw
[18:00:48] <bpuk> did you scrape in the bed mounts? I can see red marking going on there
[18:00:53] <FloppyDisk525> That's beefy, maybe good for an old english rack..
[18:05:34] <Frank_6> thanks! its a router
[18:06:27] <Frank_6> no scraping, i sent the frame to be machined
[18:07:23] <Frank_6> however i didnt get an awesome quality precision.. but for 400bucks its not that bad
[18:07:59] <Frank_6> workable for wood, and hopefully on a small area some aluminum
[18:09:11] <Frank_6> right now im a little bit nervous with my linear motion of choice, the rack and pinion spring loaded, dunno how good it will be and last for 140kg and 2x 1kw motors
[18:17:55] <bpuk> once your bed is laid in, you should be able to machine the bed to get it true.
[18:18:02] <bpuk> Whole thing looks nice :)
[18:18:23] <malcom2073> Frank_6: Tha thing is coming along really well!
[18:18:34] <malcom2073> I'm jealous :-D
[18:20:09] <Frank_6> thank you!! thats very conforting, i tend to get a little bit paranoid with the machine not working because stupid reasons hehe
[18:20:53] <Jymmm> bpuk: ..you lay in it =)
[18:21:17] <bpuk> best part is it looks like you've got enough overtravel on the X axis to actually machine the whole thing
[18:21:47] <bpuk> Jymmm: pffft. Put some comfy foam on it first
[18:22:08] <Jymmm> bpuk: like fluffy rolls of razor wire?
[18:22:40] <bpuk> Jymmm: No, comfy foam. Razor wire isn't comfy
[18:22:57] <Frank_6> i will stick some acrilyc or something like that to the red square pads on the frame to get those machined, then lay the mdf on top of that
[18:24:01] <bpuk> considered moglice?
[18:24:02] <Jymmm> SpeedEvil: I guess what I don't get is if perlite is so awesome and cheap, why are commercial applications not using it
[18:24:19] <Jymmm> SpeedEvil: ...just industrial ones.
[18:27:07] <Frank_6> bpuk: i've seen what it is but its not easy to get it here and i dont think it gives me much better performance for wood panel routing
[18:27:45] <bpuk> fair enough - personally I'd put some kind of epoxy down between the panel and the frame, then machine the frame level
[18:27:59] <bpuk> but it looks like you've considered most parts of the machine pretty well
[18:29:04] <Frank_6> hehe, ill keep that in mind thou, if the acrylic doesnt stick/keep on its position
[19:16:36] <BeachBumPete> well my new Power supply for the Cincinatti's PC is not gonna get here until thursday... Oh well ;)

[19:18:11] <tiwake> 500 mustang cars per shift
[19:18:17] <tiwake> thats production
[19:30:27] <SpeedEvil> Jymmm: it's inconsistent and harder to use
[19:30:45] <SpeedEvil> Jymmm: and has issues like settling
[20:06:03] <Jymmm> SpeedEvil: Hmmm, I made a binder using mortar. It's light, but VERY fragile. Though I think once encased in an outter metal sleeve, it'll be alright, and minimally reduce the thermal insulation properties. Right now, I'm considering 3" internal pipe, 7" outter shell, and a 2" thick filling of perlite+mortar mix.
[20:06:41] <SpeedEvil> for what?
[20:07:15] <Jymmm> SpeedEvil: thru wall stove pipe
http://www.sportsmansguide.com/product/index/hq-issue-outdoor-wood-stove?a=1884248
[20:07:46] <Jymmm> The inner pipe is aluminized exhaust pipe.
[20:07:55] <Jymmm> or would be that is.
[20:08:58] <SpeedEvil> ah
[20:09:11] <SpeedEvil> what inner temp?
[20:09:52] <Jymmm> So far, I've measured 1050F max, but giving 1200F as a buffer
[20:11:03] <Jymmm> My irgun maxes out at 1100F, but my molten salt test you figure is around 1300F
[20:13:45] <Jymmm> SpeedEvil: coffee can, perlite (loose), soup can, mostly molten salt

[20:41:33] <kyle____> woo i got the job
[20:41:47] <kyle____> time to blow all my money on a mill instead of hookers and crack
[20:44:32] <tiwake> I thought getting a mill is crack
[20:46:37] <malcom2073> No, it's a small scratch that opens the wound
[21:03:55] <Jymmm> I prefer to use a can opener to open someone's wound.
[21:06:02] <tiwake> Jymmm: P38?
[23:20:38] <Jymmm> tiwake: Nah, more like this...
http://www.finecooking.com/assets/uploads/posts/11881/ancient_opener.jpg
[23:21:50] <tiwake> oh, a larger version of the P38
[23:22:11] <Jymmm> P38 is just too small for be any real impact ;)
[23:22:21] <tiwake> thats the point
[23:22:29] <tiwake> death by the 1000th straw
[23:22:41] <tiwake> or P38 poke
[23:22:42] <tiwake> heh
[23:23:48] <Jymmm> heh
