The following description was provided: ================================================================= Bob Powell April 8, 2002 Photos plasma_cart_1.jpg and plasma_cart_2.jpg This shows a compact wheeled cart for a Hypertherm 900 that keeps the cables, consumables and other goodies together. It usually gets wheeled outdoors for use. The cart worked out well. After a couple years reflection I would do nothing different, so I figure it's time to share it. The cart was the 900's first project and reflects experimenting with it. It made all the cuts including the mitre and interlocked corners on the angle stock and the radiused cuts on the flat strips. The power unit slides into an open shelf of angle stock on the back and sides. The bins are simple pine side, plywood bottom boxes. The top bin sits on a shelf formed by the angle that frames the top. The lower bin sits on a shelf on 3 sides and slides out the front. The angle stock is all 1-1/2" x 3/16". 1/8" would have been fine but 3/16" is what I had. If you look closely at the photos you can see the angle stock that forms the two front posts is turned out, so it doesn't block the power unit and lower bin from sliding out the front. The angle stock that forms the rear posts is turned in so it blocks the back of the power unit and bin. The axles are long cap screws that screw into tapped blocks welded to the base. The handle and the five cable hangers are 3/4" black pipe capped with radiused pieces of 3/16" flat bar. The 12" rear wheels are from some Boeing Surplus junk and the front are cheap Chinese swivel casters. The filter on the back is a Motor Guard paper-cartridge coalescing filter. The bracket it came with is welded to the cart. The Hypertherm has an insulated guide tip and for cuts like this angle stock, I guide the tip using an already-trashed 12" sliding-head carpenter's tri-square (yes, metal) and drag the gun along the ruler for 90 and 45 deg cuts. To support the angle stock for cuts, I keep a hardwood block about 2" square x 10" with a different width slits cut across it to hold up the stock on edge. I.e. sticking one leg of the angle in the block holds the other in a flat, upright position for cutting. For cutting sheet and plate I use a 4' strip of aluminum as a guide bar. My usual work surface is a 2' x 4' piece of steel grating sitting on an open 55 gallon drum. Bob
