5 x 10 plasma table build

[Jimmy Southern]

Hello DSL PWR,

I Have an idea on the v groove bearings. Don't be mad if it does not work. Go to your local lawn mowing equipment center and look for v groove idler pulleys. There a little bigger than the wisecarver bearings. If you are riding the support rail like a train wheel (no side loading) they should work fine. The reason I suggested this is my local hardware store sells them for about $8.00 each which is alot cheaper than wisecarver.

Now to the eccentric bolts. I saw a really good idea for that. Take the bolt and drill and tap a hole off center in the face of the head of the bolt large enough for the correct size shaft for your bearing. You can then rotate the bolt till there is no slop then lock it down, very easy

I hope this helps
Jimmy Southern

P.S. I would give credit on the eccentric idea but I don't remember the post.

This should be able to do 1/2 plate in production, I don't plan on anything thicker than 1/4, but I like to know I have the POWER. I've also aquired (within the bounds of the law) some motors that I need some info and help on. I have 2 westamp motors and the name plate is as follows: type MT :231 Cont Current : 6.5 Max Voltage : 100v Pulse Amps : 34 Tach : 7.0 volts/1000rpm Insul : F I ripped the top cover off of the motor assm. and saw 2 heavy wires (#10) and 2 light wires (#16). The heavy ones would be for the drive pwr, but what are the light one's for? I also have a third motor that I belive is a stepper. The only thing I could get off of the nameplate is: Electro Craft Part# 0652-00-004 I need to know the specs of this motor. On top of each motor is an encoder, I think it is a 500 count. I found it on the company's web site but most of it is greek to me. BEI Motion Systems Company Model# : L25G-F2-SB-500-ABZC-8830-LED-SC18-S Part# : 924-01008-1195 Will these encoders work with a Gecko or a Rutex board? I also have 3 Bison gear boxes, the 2 on the westamps are 30.6:1, and the one on the stepper is 40:1. What lube if any is used in these? I also have a pile of cables with amp connectors. (2 for each motor, and a couple of trunks) My plan is to use the 2 west amps for the X and Y, and use the stepper for the THC. I want to use Mach2/3 for the control, and rutex or gecko drives. I also plan to use Bob Campell's breakout board an THC module if I use the geckos. The only thing that troubles me is that nasty 128 count shutdown on the gecko's. For the rails I plan to use angle (like Benny). Gear rack is my first choice for the drives, and timing belts are a distant second. It will have a water table with the capacity to handle a 5 x 10 sheet of plate. I would like to find a place that STOCKS the following items in Alberta Canada, although western Canada would do (shipping and brokerage fees from the U.S. ups the cost too much). I've found distributors in Canada for some stuff, (according to the web sites of the mfg's) but when I phone the store (ex: Bearing and Transmission) they have no clue about gear rack etc... So here is my wish list: V groove bearings Cam followers with ecentric studs Gear rack Spur gears Timing belts AMP connectors, and those neat little plyers that crimp the pins Hot, young naked blonde women I was just checking to see if you were still reading. I hope to start sourcing this stuff soon... Thanks, Carl

How does the hypertherm 1000 work. how do you turn the torch on and do you have to make contact with the metal for it to start the are. do you have to pause the torch to start the cut? I know I'm asking a lot of questions but i'm going to try the same thing this weekend.

OMG... one place want's 90 bucks for v-groove bearings! and 45 bucks for ecentric cam followers! If I can't find cheaper bearings, I'll have more money in bearings than the table!

Well I finally got my shed to a point where I can use it.
I've nearly completed my water table. It really sucks when you pressure up the table the 1st time and water starts sqirting out... I guess you can't expect perfection in all 120 ft of weld. THe sad part is all but one leak was in the last 20 feet of weld. I guess I need to learn to take more breaks!

I'll post some pics when I find my camera.

Still not found that camera?? LOL

got you table going?

[DSL PWR]

I know It's been a while since I've been on this thread, but I've been busy with work and my haas tm-1. I was about to take some pics lat night but my camera is NFG.

When I ordered my pinion gears 6mo ago I screwed up the calc in a big way. After I test run the motors I did the calcs again and my max speed would have been over 1800 ipm!! OOPS!! I just ordered the correct pinions and should end up with about 500ipm.

Well it cuts. I still need to do some things, but at least there is a light at the end of the tunnel (it's still a ways off, and may be a train...)

DSL PWR, nice job, Look awesome cutting in the water tank.

Keep up the great work and keep posting pictures.

I'm sure your persistence with the project has put a big smile of satisfaction on your face.
Nice edge cuts on the slotted section.

Here are may slat holders and a 150gpm water pump

Hey, why does your water pump sound like an air compressor? It seems to displace a lot of water initially then it slows way down.... I think you need a bigger reservoir, then a bigger exhaust valve.

Man, could you have scrounged any bigger motors to drive that sucker? Looks like something from an ESAB Puma ;-)

Got my THC working.
