A very long time ago I had a Park Truing Stand....it was OK and maybe the newer ones are better. E-bikes are hard on wheels and I want to have a stand available so why not build one? I am constantly rebuilding machines in my factory and have used 1" Thompson linear shafting available. I have not put the dial indicators on the stand yet, but when I do, the stand should be accurate to about .001". Besides it was fun to build! I'll update the thread with more pictures when the indicators are mounted.
