RE: CNC Plasma Table - stevec - 02-09-2014
Greg, while I was dreaming of making a CNC plasma table I thought of anchoring it to a wall so it could be "swung" down for use and "swung" up to get it out of the way. I have since realized I will NOT be making one, it's just another "pipe dream".

Never paid any attention to the fact or this is odd rectangular tubing but the sides are bowed. Was going to drill and tap the holes for the rails to mount when I noticed this. Ended up drilling then making plugs, welding them in and milling the tops flat while supporting the tube at its edges.

Ordered an electronic package for it today from http://www.candcnc.com
Pricey but its supposed to be the complete package assembled and tested. This way I can let the magic smoke out of a working system.

Got the side frames drilled and tapped. When I put the two face to face with the bosses touching there's a 1/16 or so bow in the middle, hard to tell if they're both or one bowed Will be able to shim the rails to get a straight track.

Oh the gantry came in at 30 pounds without the steppers.

Get some thin piano wire, arrange to tension it down the length of your beams, and you'll soon see which are squiffy

The major frame work is complete. Bigger than I envisioned, going to take up a lot of real-estate.
Want to try using a water table to catch the dross and smoke, now need to find 5 x 5 foot steel.

At least you'll be able to move it around if it gets in your way.

Now if you made those legs able to telescope to a lower level, and made a frame to sit over all the gubbins on top, you'd have a fine work table for when you're not plasma cutting. It's the amount of space they take up that's stopped me making one over the years
RE: CNC Plasma Table - f350ca - 02-16-2014
This was probably one of the most impractical to build things I've ever made. Needed cable track and had no idea where to buy it in this area, Im sure its cheaper to buy than build.
Had a stack of aluminum tags that were remarkably sized well. cut them in two and sandwiched the stack with dowels and went to milling.
A router bit makes a great rounding over cutter for aluminum.

Set up some jigs to position them in the brake.

Seams to roll nice and stays straight in the one direction.

RE: CNC Plasma Table - stevec - 02-16-2014
Boy! I'm glad I came to my senses about a build like this. I've got a guy "round the corner" that'll cut up to ½" for me . I'll just use him when I need a few parts cut.
Good job Greg, glad your doin' it, not me.
BTW I'm still really enjoying your progress!
RE: CNC Plasma Table - f350ca - 02-22-2014
Pretty much ready for paint.
