I also use an old swingarm clamped in a vise. I use flat washers outside both sides of the factory spacers on a axle I found long enough to span the swingarm width for front wheels. Seems like it is a SR500 or RD400 rear axle, but not sure.
Catch a good ol' Harbor freight sale on the dial indicator and magnetic stand. I use a pencil with one of the big orange erasers (they leave a light mark) in the magnetic mount for a pointer, and then the dial indicator for fine tuning...the eraser marks polish out easy on alloy rims.
It does take some time to get comfortable with it like Hugh said.
Maybe I am a normal person after all! LOL
