I needed some outfeed rollers for my table saw and I also wanted to use them for my horizontal band saw and my compound miter saw.  My brother-in-law gave me alot of 1/2" x 1-1/2" x 1/16" rectangular steel that he got from the local mall when he worked there.  The steel was used for some kind of shelving display.

I also bought 24 rollers off of ebay for $3.00 each, 10 are 20" and 14 are 16" so the cost for these were $95.00.  I also had 48 feet of 1-1/2" x 1-1/2" x 1/8" square tube that I bought for a different project but decided it was too heavy.  I acutally wanted 1" x 1" x 1/16" but the local supplier couldn't get it and ordered the larger metal instead.  This metal would of made my portable compound miter saw stand not very portable.

The rectangular steel for the frames is 4 feet long.  I drilled 5 equal spaced 1/2" holes starting from 2-1/2" from each end for the roller axles to fit in to.  After I welded the frames I noticed that they flexed from side to side enough for the middle rollers to fall out of. This was solved by welding a 1/16" x 1" steel bar to tie the two frame rails together next to the middle roller.

Next I took some 2" x 2" x 1/8" angle steel and cut off 16 pieces 4-1/2" long. Then I took 16 pieces of angle steel and cut it down to slightly over 1-1/2" x 1-1/2" x 3" to form the outer side of the leg sockets, I placed a section of the leg metal between the two and welded the angles together, then to the roller frames.

For the legs I thought about making them foldable, but if I did this it would add to the cost and I would have to make bracing to keep the legs from collapsing.  This is when I came up with the socket idea.  The legs are 33" long x 1-1/2" x 1-1/2" square tube. I cut 16 pieces of 3/4"-10 all thread 6" long. Took the nut and a washer and welded them to one end of the all thread. Placed a 3/4"-10 nut into the leg tube and welded them in place.
