Hi PG,
The only pieces I bought for the stand were the casters, $3.98 @ if I remember right. The pipe and aluminum were in my jun -oops - stock pile. The spools are screwed tight to the stand, don't rotate. They'd also be easily changed for other applications. The design came from looking at ads and was inspired by the price tags. There aren't any dimensions, I used a couple of tape measure figures to get started and just built it to fit, tweaked it to fit right. The pipe can be fine tuned cold. I'll make a front stand sometime, but living on a dirt road chain maintenance is a priority. I clean mine with a dry toothbrush, it's a tedious proces but gets down to bright metal and doesn't wash mung into the O rings. So, if you have tools or access to them, pipe is cheap. You could use a pair of 1" or 1 1/4" pipe couplings for the spools, weld them in place and wrap them in Gorilla tape. Wheels could be as close as the curb on garbage day. Get yer wheels spinning.
