I have a Park TS-2 and use dial indicators.The last three wheel sets I have built and maintain have machined sidewalls. Velocity Psycho, Andra 30 and Andra 40 rims. I use Parks dial indicator holders for their stand. I have better dial indicators that read in the thousands. So I use these instead of the metric ones that came with the Park setup. The machined sidewalls allow the dial indicators to work pretty smoothly. I also have the holder for the dial indicator to check the rotors.I am able to get .005 TIR on wheels and rotors.
