[00:36:11] <tjb1> Is there a wildcard I can use in gedit to remove N numbers?
[00:36:25] <tjb1> Like Find N**** and replace with " "
[00:36:28] <FinboySlick> tjb1: Would be better with vi.
[00:36:50] <FinboySlick> :%s/^N....//
[00:37:16] <FinboySlick> tjb1: I can guide you through it if you're feeling adventurous.
[00:38:59] <tjb1> Not that adventurous tonight
[00:39:04] <tjb1> Was hoping the **** would work :(
[00:40:47] <FinboySlick> Is N the first character of the line?
[00:40:52] <FinboySlick> (always)
[00:40:54] <tjb1> Yes
[00:41:10] <tjb1> Ill eventually edit the post so I dont have to do this
[00:41:30] <FinboySlick> Then the separator is a space or a tab?
[00:41:48] <tjb1> Just N0010, N0020, etc...
[00:42:01] <FinboySlick> I mean for the rest of the line.
[00:42:20] <FinboySlick> N0010 G0 X0.5
[00:42:35] <FinboySlick> Space between your N word and your command?
[00:42:37] <tjb1> space
[00:42:40] <FinboySlick> OK.
[00:43:04] <FinboySlick> sed -e's/^N.... //' badfile.nc > goodfile.nc
[00:43:56] <tjb1> And where do I do this?
[00:44:06] <tjb1> terminal?
[00:44:10] <FinboySlick> Yes.
[00:44:49] <tjb1> What is //'badfile.nc?
[00:44:56] <tjb1> Can I just drag the file name or is //' separate
[00:45:48] <FinboySlick> sed is sort of a text-editor robot. -e's/^N.... //' basically tells it to do a search and replace. badfile.nc is your input filename.
[00:46:19] <FinboySlick> Default is to dump the output to the screen. You can use > somefile.nc to redirect that output to a file.
[00:46:30] <FinboySlick> If you just want to test, omit the > goodfile.nc part.
[00:47:28] <FinboySlick> If you saved your file to the desktop, launch a terminal.
[00:47:32] <FinboySlick> cd Desktop
[00:47:37] <FinboySlick> then run the command.
[00:47:53] <tjb1> amazing, thank you
[00:48:16] <FinboySlick> tjb1: You can just type the first few characters of your filename and hit tab for completion.

[02:09:16] <Tom_itx> tweaking what?
[02:09:27] <tjb1> Settings...
[02:09:36] <tjb1> The accel and stuff were too high so it was being jerky
[02:09:43] <tjb1> Here is first part :) - http://www.youtube.com/watch?v=BhL17PuXEGw
[02:10:07] <tjb1> And this is where more tweaking needs done - http://sphotos-a.xx.fbcdn.net/hphotos-snc7/389481_4444718432061_2133760431_n.jpg
[02:11:37] <FinboySlick> tjb1: Why are all the other related videos about pro wrestling? ;)
[02:11:47] <tjb1> no idea
[02:11:57] <Tom_itx> mine aren't
[02:11:59] <tjb1> Not related to pro wrestling on mine ;)
[02:12:30] <Tom_itx> so adjust your backlash comp
[02:12:37] <tjb1> Its the lead in
[02:12:52] <tjb1> I had an arc lead in but I think I am going to try tangent
[02:13:23] <Tom_itx> ready to set up your home button?
[02:13:57] <FinboySlick> tjb1: I'm not very familiar with plasma tables but I'm trying to understand why you need that kind of floating portion on Z? Shouldn't you just barely touch, register contact and go to set height?
[02:14:24] <tjb1> What am I going to register contact with?
[02:14:45] <tjb1> You can use an ohmic sense which senses the tip contact with material but I dont trust it with material like I just run
[02:14:58] <tjb1> The plasma itself had a hard time starting on the first hole it was so rusty
[02:15:03] <FinboySlick> I meant the amount of travel you need to get the contact.
[02:15:15] <tjb1> I mounted the switch bracket too high
[02:15:30] <tjb1> Im going to add a screw to get that down to like .1"
[02:16:18] <FinboySlick> OK. Is there a situation where that much travel is useful though?
[02:16:45] <tjb1> Not on the floating Z
[02:17:30] <tjb1> I was in a rush to get that plate done and just put the bracket where I thought it would work because I didnt have the sensor with me either…it works but it takes a little while
[02:17:55] <tjb1> Torchmate(the company itself) uses ohmic but they are using brand new steel all the time so its no problem for them
[02:18:36] <FinboySlick> OK. It wasn't really a critique on the design, just a way to understand things better.
[02:19:08] <tjb1> Just working with what I had too :)
[02:19:21] <tjb1> Those slides were initially for a plate marker but they dont have enough travel
[02:20:45] <tjb1> Anyone know what a tangent lead in on the inside of a hole looks like?
[02:21:16] <Tom_itx> starts in the middle and goes to the start of the arc
[02:21:22] <Tom_itx> i do those on mill cuts
[02:21:41] <tjb1> Any idea what would work best to eliminate the oblong holes?
[02:21:59] <Tom_itx> backlash comp?
[02:22:04] <ReadError> tjb1, does the school pay for it?
[02:22:09] <ReadError> or you gotta fund everything yourself?
[02:22:14] <tjb1> Its all mine
[02:22:35] <Tom_itx> did you measure backlash?
[02:22:39] <tjb1> Tom_itx: There is no backlash in it, its spring loaded rack and pinion
[02:23:07] <Tom_itx> jt would be the one to ask about plasma
[02:23:15] <ReadError> tjb1, how much you estimate the project is?
[02:23:24] <tjb1> Once I get water table, around 3k
[02:23:32] <ReadError> oh thats not bad
[02:23:43] <Tom_itx> what sort of power source on the cutter?
[02:23:59] <tjb1> What the cutter plugs into?
[02:24:12] <Tom_itx> i don't know much about em
[02:24:19] <tjb1> Its just 240v
[02:24:36] <Tom_itx> no transformer?
[02:24:39] <ReadError> why are all these larger mills low rpm motors :(
[02:24:42] <tjb1> inverter
[02:24:44] <ReadError> i might need a routing table
[02:24:53] <Tom_itx> tjb1, ac or dc?
[02:24:53] <ReadError> i need to do atleast 10k rpm
[02:24:56] <ReadError> maybe even higher
[02:25:46] <tjb1> dc
[02:26:03] <tjb1> Tom_itx: http://www.hypertherm.com/en/Products/Handheld_cutting/Systems/powermax45.jsp#specs
[02:26:24] <tjb1> I need to find which way to cut circles too because of the swirl cup
[02:28:38] <Tom_itx> so you bought a manual one and made the table
[02:29:30] <tjb1> yes
[02:30:13] <Tom_itx> are you using their feed recomendations?
[02:31:01] <tjb1> Yep
[02:31:17] <tjb1> Reading up on some of jims post, holes need cut CCW, long lead in, no lead out
[02:31:22] <tjb1> 60% of normal feed
[02:31:57] mutil is now known as mutilator
[02:32:47] -!- skunkworks__ has quit [Ping timeout: 240 seconds]
[02:32:55] <tjb1> I found out why home was never setting coordinates to 0…I needed to add g92.1 to every program that uses the torch height index or it screws it all up

[02:44:40] <tjb1> Tom_itx: Is there a g-code to rotate work?
[02:45:12] <Tom_itx> umm, not that i'm aware of
[02:45:23] <Tom_itx> there may be but not one i've used much if ever
[02:46:42] <Tom_itx> what do you mean?
[02:46:48] <Tom_itx> change the x and y axis?
[02:48:19] <tjb1> Sorry found it, G10 L2
[02:48:44] <Tom_itx> that doesn't rotate it though
[02:49:19] <tjb1> It has R - Rotation about the Z axis
[02:50:14] <Tom_itx> maybe for a lathe
[02:50:45] <Tom_itx> i dunno
[02:51:03] <tjb1> It did rotate it but now I cant figure out the 0
[02:51:10] <Tom_itx> heh
[02:51:40] <Tom_itx> it would be what you had the P word set to
[02:51:56] <Tom_itx> 1 would be the G54 offset values
[02:52:01] <Tom_itx> 2 would be G55
[02:52:01] <Tom_itx> etc
[02:52:08] <tjb1> Not 0?
[02:52:14] <Tom_itx> not active
[02:52:17] <tjb1> 0 says active…maybe I need to change it to 1
[02:52:21] <Tom_itx> http://www.linuxcnc.org/docs/html/gcode/gcode.html#_g10_l2_set_coordinate_system_a_id_sec_g10_l2_a
[02:52:55] <Tom_itx> i dunno without testing it
[02:53:08] <Tom_itx> maybe 0 is the currently active fixture offset
[02:53:09] <tjb1> Screw it, Ill redraw it lol
[02:53:15] <Tom_itx> naw, figure it out
[02:53:31] <Tom_itx> it's how we learn
[02:53:36] <tjb1> Well I figured out how to rotate it in sheetcam
[02:58:02] <Tom_itx> is that free to use?
[02:58:12] <tjb1> I think for 180 lines
[02:58:16] <Tom_itx> k
[02:58:18] <tjb1> I rotated it and its still screwd up...
[02:58:22] <Tom_itx> i was thinking someone said it was
[02:58:30] <Tom_itx> what's wrong with it?
[02:58:39] <tjb1> Its moving in y versus x
[02:59:12] <Tom_itx> what exactly are you trying to do?
[02:59:19] <tjb1> Ok I have a problem…the G code is moving in X direction but the machine is doing it in the Y direction
[02:59:24] <Tom_itx> did you reload the gcode?
[02:59:29] <tjb1> Yes
[02:59:36] <tjb1> I just restarted axis, hold on
[02:59:49] <Tom_itx> X is axis0
[02:59:53] <Tom_itx> y is axis1
[03:00:04] <Tom_itx> normally
[03:01:22] <tjb1> restarted linux cnc and now its going the correct way...
[03:01:43] <tjb1> These offsets are killing me, especially using the G92
[03:03:02] <Tom_itx> what's it doing and what are you trying to accomplish?
[03:03:40] <Tom_itx> i use G54 normally
[03:03:44] <tjb1> I think a code was still active before…specifically the G10 L2 and it kept going it the wrong direction
[03:04:00] <tjb1> I need to make a good startup line to cancel everything
[03:04:08] <Tom_itx> hang on
[03:04:42] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/enc_hub.txt
[03:04:43] <Tom_itx> that's a sample of my post
[03:05:16] <tjb1> I am using G92 to set the torch height though
[03:05:41] <tjb1> and if not cancelled it screws everything up at least on the read out, but since every probe resets it, it cant really harm the toolpath
[03:06:24] <tjb1> Every time I start linuxcnc and home it, it never sets the coordinates to 0 and I havent tested it yet to see if the soft limits are working off the coordinates it sets or if it is physically setting that point to 0 and just displaying something funny?
[03:06:38] <tjb1> I have to go into Machine and reset G54 coordinates
[03:07:21] <Tom_itx> why do you need G92 for the torch?
[03:07:38] <tjb1> It sets the height when the input is activated
[03:10:01] <tjb1> My torch lowers until input actiavted, does an incremental move the distance from floating until input activate, G92 Z0.0, G1 z.160, m3s1, waits for torch ok, z.060
[03:16:59] <jdh> why g92 instead of just set z in g54 (g10 l2 p1 z0)?
[03:18:49] <tjb1> Im just using jts code
[03:19:00] <jdh> should work then.
[03:19:35] <jdh> I tried g92 a few times. Or I tried to try it anyway. It never did what I expected the second time.
[03:20:39] <jdh> what would be the smallest plasma table that would be useful?
[03:21:04] <tjb1> Whatever you work with
[03:21:36] <jdh> I don't work with anything, it just looks cool
[03:21:59] <jdh> does the kerf change size from top to bottom on thicker material?
[03:22:29] <tjb1> yes
[03:22:52] <jdh> can you angle the torch head to get a square through cut?
[03:23:14] <jdh> on one side anyway
[03:23:49] <tjb1> I suppose if you wanted to lol
[03:24:52] <Tom_itx> jdh, rotary head?
[03:27:05] <jdh> it would need to me more than just rotary
[03:27:16] <jdh> guess if you cared about precision that much, you wouldn't use a plasma cutter
[03:27:23] <Tom_itx> heh
[03:27:26] <Tom_itx> i suppose
[03:28:16] <jdh> but, with the torch in a ball joint or something and coordinated movement, you should be able to keep the plasma path perpendicular to the finished side
[03:28:37] <tjb1> If you need that good of a cut you should be using a high def plasma
[03:28:48] <jdh> or wire edm
[03:29:02] <tjb1> sheetcam needs an option to overlap leadin-leadout a certain amount...
[03:33:16] <r00t4rd3d> with Aspire you can.
[03:33:47] <r00t4rd3d> you probably can with shitcam too
[03:33:53] <tjb1> Might be using that for plasma...
[03:33:58] <r00t4rd3d> you just need to figure out how
[03:34:11] <tjb1> Problem is its leading in/out at the same point so its not cutting that area at full plasma width
[03:34:19] <tjb1> No I looked it up and they dont have it yet
[03:34:36] <tjb1> Well that post was 2 years ago so maybe the windows version has it
[03:34:46] <r00t4rd3d> over lap the vectors in your design
[03:34:51] <r00t4rd3d> by a touch
[03:34:58] <tjb1> You cant pick stuff like that in sheetcam
[03:35:15] <tjb1> you put all holes on a layer and set toolpath to inside offset and it does it
[03:35:26] <tjb1> It doesnt even use cutter comp…it offsets the toolpath
[03:35:54] <tjb1> Piss poor options I think but I guess it is cheap
[03:36:21] <tjb1> r00t4rd3d: Can you post code of one hole for me with overlap lead in/lead out arcs?
[03:37:41] <r00t4rd3d> probably not
[03:37:59] <tjb1> :(
[03:39:36] <r00t4rd3d> how big a hole?
[03:40:20] <tjb1> https://dl.dropbox.com/u/3090951/1hole.dwg
[03:40:33] <tjb1> or .304 if you wanna do it yourself
[03:40:40] <tjb1> .050 cutter width
[03:42:35] <tjb1> Do like .125 overlap on the leads if you can please

[03:55:32] <tjb1> thanks
[03:55:37] <tjb1> better be a circle this time :P
[03:55:48] <r00t4rd3d> lol
[03:55:52] <r00t4rd3d> you should cut that
[03:56:22] <tjb1> Oh did you go counter clockwise?
[03:57:05] <r00t4rd3d> no clue
[03:58:18] <tjb1> Why are there 2 circles?
[03:58:47] <r00t4rd3d> cut depth probably
[03:59:54] <r00t4rd3d> yeah, material was set to .25 , cut depth .125
[04:00:03] <r00t4rd3d> 2 passes
[04:00:33] <tjb1> Does that lead in and out to the center of the circle?
[04:01:06] <r00t4rd3d> ive never used the lead in or out stuff
[04:01:18] <r00t4rd3d> only overcut
[04:01:38] <r00t4rd3d> looks like it just leads in/out to the tool path
[04:02:33] <r00t4rd3d> why do you even use the lead in/out?
[04:03:27] <tjb1> Because it blows a bigger hole than kerf when piercing
[04:03:35] <tjb1> If you start on the profile it screws it up :)
[04:03:45] <r00t4rd3d> also was set ot conventional so clockwise
[04:04:16] <tjb1> The hole on pierce is like .09" big or bigger
[04:05:11] <r00t4rd3d> i need to go out and start another box
[04:05:39] <tjb1> good luck

[15:24:50] <spiderdijon> hi, each of the axis on my machine is capable of 10IPM how do I go about limiting each individual axis to that speed instead of the combined speed of all the axis'? So effectively all axis could be moving at 10IPM giving a total speed of 30IPM. LinuxCNC seems to by default limit the overall speed.
[15:26:15] <Tom_itx> set it on a per axis basis
[15:26:19] <Tom_itx> in the ini file
[15:26:27] <Tom_itx> [axis0..x]

[15:26:50] <Tom_itx> STEPGEN_MAXACCEL
[15:28:08] <Tom_itx> i doubt you get 30ipm though
[15:28:24] <Loetmichel> hmmm
[15:29:16] <Loetmichel> can anyone pint me in the right direction where to configure linuxcnc to always retract z FULL at (manual)tool change?
[15:29:32] <spiderdijon> ok great thanks
[15:29:33] <Loetmichel> ... so i can get the tool out/in without stopping the programm?

[15:31:30] <Tom_itx> probably with an M5
[15:31:57] <Loetmichel> Tom_itx: i thought more of a possibility to execute a macro at toolchange or so
[15:32:37] <Tom_itx> i generally put a toolchange point in my programs so it's clear of things
[15:33:06] <Tom_itx> you could put that in a macro if you wanted
[15:34:00] <Tom_itx> i just added a couple lines to my cam post
[15:34:47] <mhaberler> Loetmichel: look at http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=tree;f=configs/sim/remap/manual-toolchange-with-tool-length-switch;h=4c79703b3b22f6d43949e91f97d1fe5b186a34fb;hb=ce55978c1af6941c101cd2a7191c3fe810888fd1

[15:35:08] <mhaberler> that's the most flexible form currently possible
[15:37:02] <Loetmichel> aha
[15:37:40] <Loetmichel> hmm... dont understand a thing. is there a howto that i understand what the changes in the ini and hal files do?
[15:37:49] <Loetmichel> thx anyway
[15:38:13] <mhaberler> there is a thing called 'manual', and it is here: http://www.linuxcnc.org/docs/devel/html/remap/structure.html ;)
[15:51:23] <Loetmichel> mhaberler: could you be a BIT more specific with your links? i meant a text whre is laid out what this modification DOES
[15:51:51] <Loetmichel> i tend to want to understand what i am modifying there
[15:53:43] <mhaberler> I'm a bit unsure how I should respond - there are several complete working examples, and the manual as reference; maybe the introduction helps: http://www.linuxcnc.org/docs/devel/html/remap/structure.html#_getting_started_a_id_remap_getting_started_a

[16:09:40] <cradek> the simple answer to this question is the tool change quill up flag
[16:24:23] <Loetmichel> mhaberler: after sonme seroius reading: nice mod, but WAY to much.
[16:24:58] <Loetmichel> i need no tool switch as my tools have the plstivc rings which serve as a lenght stop in the ER11
[16:25:14] <mhaberler> fine, then go for cradek's suggestion
[16:25:19] <Loetmichel> so all tools are same length from chuck to tip
[16:25:34] <Loetmichel> i just need enough room to change the tool manually
[16:26:07] <mhaberler> you asked 'to execute a macro at toolchange or so', this is what you asked
[16:26:27] <Loetmichel> as i use BoCNC i would have to do that manually in _every_ gcode
[16:26:59] <Loetmichel> ... waht is waht i do now. i just wanted to do that in the machine so i can omit the work

[17:37:30] <r00t4rd3d> i guess you just change out a few ceramic capacitors
[17:38:06] <r00t4rd3d> but they are surface mounted chips, not to fun to solder
[17:38:17] <IchGuckLive> it is fun
[17:38:24] <IchGuckLive> i did it on 30+ boards
[17:38:34] <r00t4rd3d> ich you see the ebay link i posted? would those work ?
[17:38:46] <IchGuckLive> just hit them with som solder on the header and they are gone
[17:39:01] <IchGuckLive> yes they do
[17:39:08] <r00t4rd3d> New Kemet 1206 Size 150pF, 50V, C0G, +/-5%, Surface Mount Ceramic Capacitor
[17:39:16] <IchGuckLive> but i woudt go for the TV shop
[17:40:19] <IchGuckLive> and if you are a freek change the 20+ Diods from FR304 1ms to UF5407 100ns time
[17:40:49] <IchGuckLive> this gives your Power suppply a maximum stability
[17:41:12] <IchGuckLive> im off By

[18:28:31] <L84Supper> it's was all fun and games as a kid until the wind changed direction one day :)
[18:28:59] <pcw_home> I used 9x12foot .0005 mill dropcloths (and a bunch of scotch tape)
[18:30:47] <L84Supper> pcw_home, helium filled or hot air?
[18:30:50] <pcw_home> no fire, just filled with hot air from a campstove and tied off

[18:36:41] <pcw_home> No but we used I think it was telephone wire to tie off the open end
[18:36:43] <pcw_home> (it took three people to hold the edges of the bag over the campstove and then quickly tie off to ascent)
[18:37:40] <L84Supper> heh... back in the 70's when it was just considered fun

[21:49:40] <djdelorie> Today I was jogging my machine, thinking "you know what would be cool? if shift-arrow did a high speed jog". So I tried it. IT WORKED! Good job on that one :-)
[21:52:03] <pfred1> djdelorie want to see my wooden linear guides?
[21:52:10] <djdelorie> sure
[21:52:18] <pfred1> http://i.imgur.com/nnTz3.jpg
[21:52:25] -!- Aero-Tec has quit [Ping timeout: 256 seconds]
[21:52:37] <pfred1> and http://i.imgur.com/8rTnD.jpg
[21:52:47] <djdelorie> will you be adding capture bearings too?
[21:53:00] <pfred1> djdelorie you're into woodworking so I figure you can appreciate it
[21:53:05] <djdelorie> yup :-)
[21:53:24] <djdelorie> my cnc table is currently all clamps and glue again :-)
[21:53:39] <pfred1> my machine is going to be plunk it down and go
[21:53:48] <pfred1> it won't have a table really
[21:53:58] <djdelorie> my next task is to write a routine to mill pocket screw holes with a 1/8" router bit
[21:54:03] <pfred1> it is going to stand up on legs
[21:54:11] <djdelorie> ?
[21:54:17] * djdelorie is missing a concept here
[21:54:28] <pfred1> just how it is going to work you could attach it to a table but it'll run without one
[21:54:49] <djdelorie> what would you attach it to otherwise?
[21:54:53] <pfred1> like you could just drop it on a sheet of plywood and start cutting
[21:55:07] * djdelorie is wondering if it could mill 2x12 rafters on-site...
[21:55:15] <pfred1> it should be able to
[21:55:27] <pfred1> if you could clamp it to it
[21:55:39] <djdelorie> I did my shed's rafters with a router and template. Everything lined up perfectly and I didn't have to "guess" on anything
[21:55:39] <pfred1> it should run at any angle too
[21:55:42] <pfred1> like on a wall
[21:56:08] <djdelorie> are you still in the "I wonder if this will work" stage?
[21:56:16] <pfred1> I've been running my Z axis on its side it seems to work
[21:56:28] <pfred1> well today was a big step
[21:56:36] <pfred1> that one truck runs smooth
[21:56:45] <pfred1> like really smooth
[21:57:16] <djdelorie> if you made those wooden blocks the bearings are on wider, you could add a second set of bearings on the other side of the rail board to capture it
[21:57:23] <pfred1> I'll see when I get the whole Y axis together but so far it is looking good
[21:57:42] <pfred1> well it will be captured this is on its side
[21:57:51] <pfred1> there will be another rail opposite of it
[21:58:06] <pfred1> let me find a sketch of the design
[21:58:06] <djdelorie> ah
[21:58:39] <djdelorie> if the whole thing will be made of wood, full capture on both sides might be better
[21:59:03] * djdelorie wonders if pocket screws would be the "right" way to attach those blocks...
[21:59:23] <pfred1> I was wondering if I shouldn't screw them down so I could adjust them if I need to
[21:59:27] -!- rob__H has quit [Quit: Leaving]
[21:59:47] <pfred1> but I figure I'll just make a jig so when i glue them they're dead on the same
[22:00:00] <djdelorie> they won't need adjustment until you have both sides done :-)
[22:00:23] <pfred1> yeah that is one question I still have will it bind when it is all together
[22:00:39] <djdelorie> if you used a slot for the bearing's bolt, and milled the slot at a slight angle, you could adjust it by just moving the bearing bolt in the slot
[22:00:49] <pfred1> yeah I thought about that
[22:00:59] <djdelorie> but I'd switch to a hardwood block if you're going to mill that much out of it
[22:01:28] <djdelorie> and you'd definitely need opcket screws and glue at that point, because the slot would interfere with screws from the outside
[22:01:41] <pfred1> well this is a really early sketch and the rails are actually reversed from how I ended up doing them http://i.imgur.com/lysGP.jpg
[22:01:48] <djdelorie> unless the bearings were more centered...
[22:02:57] <djdelorie> the weight of the carriage in either of those configurations would cause the sides to spread out... ?
[22:03:11] <pfred1> this is a half a side http://i.imgur.com/8Y11S.jpg
[22:03:33] <pfred1> about the spreading I'll let you know but the 3/4 ply with those rails on them is pretty beefy
[22:03:42] * djdelorie thinks it needs a separate load-bearing bearing
[22:03:45] <pfred1> my X axis is only going to be 3 feet
[22:03:56] <djdelorie> plywood is *not* strong in that particular direction
[22:04:06] <pfred1> but it is with those rails glued to it
[22:04:20] <pfred1> it is like an engineered beam then
[22:04:25] <djdelorie> do some googling about "hardwood shelf sag calculator"
[22:05:01] <pfred1> I've dry fitted some pieces here it seems pretty solid to me
[22:05:14] <djdelorie> I suppose it depeds on what tolerance you need, too
[22:05:32] <pfred1> oh yeah I'm only looking to do decorate routing with this
[22:05:53] <pfred1> whatever it is off will just be artistic license as far as I'm concerned
[22:06:11] <djdelorie> if it *does* sag, it's easy to use pocket screws to add a brace to the middle of the outside of the side
[22:06:21] <pfred1> although if it works like I thnk i may remake it in steel
[22:06:43] <pfred1> this is just the prototype to check the design
[22:07:17] <djdelorie> or 8020 with linear bushings?
[22:07:32] <pfred1> nah I'll use hot rolled angle iron
[22:07:37] <pfred1> nothing fancy
[22:07:48] <pfred1> maybe I'll belt sand the bearing faces
[22:07:57] <pfred1> get the scale off
[22:08:51] <djdelorie> of course, if you have a cnc machine you can mill vertical braces out of hardwood plywood to attach the angle brackets to to hold them in position :-)
[22:09:13] <pfred1> well I have a milling machine now
[22:09:22] <pfred1> it just isn't CNC
[22:09:43] <djdelorie> I have one of each. A mill that isn't cnc and a cnc machine that isn't quite a mill
[22:10:11] <pfred1> I need to use my mill by hand too much to CNC it
[22:10:38] <pfred1> plus it'd cost me a fortune to get new leadscrews for it
