I picked this up a few years ago, its been floating around in my garage for a while with no base, I finally decided to make use of it.
Its made from 1 1/4" water pipe and some bolts covered in vinyl tubing.
I made the base from 3/8" plywood, I went with the 3/8" because they had a half sheet of exterior 3/8" ply for $3 in the scrap bin. I cut the 1/2 sheet in four equal pieces, glued it together with marine wood glue, then cut it to 20x24". I put adjustable feed on the bottom, I counter drilled four 1/2" nuts and epoxied them in place at each corner. It keeps the wood off the concrete incase it ever got wet too. I sanded and coated the whole completeled base with 5 coats of marine Spar Varnish I had here.
Its perfect for working on old balloon tire and three speed bikes, it works for some drop bar bikes but not with those with bottom cables if you want to shift the gears on the stand.
