I think I’ve mentioned that I did build several wheels sets for the Sprint in recent time.
A P&K Lie truing stand is slightly out of my reach and I hesitated spending money for a cheap truing stand when I could build one myself.
A length of 25 x 3 mm aluminium tube, a piece of 40 x 60 mm aluminium bracket, a M10 all-thread rod and an old dial indicator where at hand, the piece of water-resistant plywood, a piece of zink-plated steel plate, some washers and some M10 nuts came from the local hardware store. Ebay provided the cheap magnet stand for the dial indicator.
The construction is fairly simple. A piece of 15 mm plywood as a base, two pieces of thread rod, two pieces of aluminium tube, two brackets to mount the wheels, three M10 drive-in nuts to screw the thread rods to the plywood base, four M10 nuts, four washers. The steel plate is glued to the plywood to provide a base for the magnet stand. I’ve drilled three holes in the plywood to mount the stands accordingly for 100 mm and 135 mm wide hubs.
Shame on me that I didn’t remember how much I’ve learned to hate these cheap Chinese magnet stands for dial indicators when working with grinding machines. Since you don’t true a bicycle wheel to 0.01 mm I thought I can get away with a cheap €25 magnet stand. It works ok, but next time I’ll get a better one anyway.
It works quite well as a crude hub motor test stand too. That’s my new Bafang BPM2 btw. (and my cat)
