Customized Truing Stand
No, this isn't yet another question thread.
I've had my Minoura Pro folding truing stand for about 12 years or so and have used it for mobile race support work. After a while the plastic yoke broke, was repaired, and finally broke to the point it was unfixable...until recently.
With an old cantilever brake booster, a couple disc brake adapters, some sheet aluminum, a couple punk spikes, a block of wood and a little time in the shop...I'm happier with it than I ever have been. Here's the result:
The block of wood took the most work, serving as a friction mount for all the rest. I had to drill and countersink it for some tee nuts, for the booster mounting screws and for the vertical runout gauge mount.
The idea for the vertical gauge came from my old VAR stand used in my home shop. The Minoura originally came with a gauge that required turning a screw on the bottom of the yoke, which was time consuming and if the rim had a burr would catch and throw the yoke off. It also had to be removed when truing a wheel with the tire still on...frustrating. The aluminum makes an easy to hear resonating scrape, and if caught, flips out of the way. It also flips easily to make room for a tire.
I re-used the original lateral adjustment screws, removing them completely from the old yoke, brass bushings and all. The brake adapter was drilled and the bushings pressed into place, then the assembly was bolted to the brace. This worked fine other than the brake booster was wider than the old yoke, so I extended the feelers by retapping some chromed brass punk spikes and replacing the original acorn nuts. The points allow much better visual sighting of runout and make a loud scraping noise. The brass is soft so it won't harm rims.
I was still having issues with truing wheels with the tire on as the thread pitch on the feelers is very fine and had to be screwed out to accept the tire, then screwed back in...that is, until I figured out that if I loosened the mounting bolts to allow movement with enough friction to hold them, they could be twisted out of the way, then twisted in.
The best part is that it all still folds up compactly for transport, and if it ever breaks I can just replace the parts myself.
If you're wondering what the reflector is for, I've been playing around with a mount for a rotor truing gauge. I'd also like to extend the arms for 29er wheel clearance, but for now it's pretty darn handy.

Excuses? I just recently built myself a 650b IGH/dynamo wheelset. I must admit, I used the VAR and not this stand...but I certainly could.
