383 Harmonic balancer question

Just for the fun of it.

Make up a tubing shaft 18" long to fit the ID of whatever balancer you want to check for neutral balance. Find a way to chuck the shaft up in your 500 rpm 1/2" drill.

Install a Pillow Block bearing in the ceter of the shaft and clamp the pillow block housing in the vice.

Slide the snug fit balancer over the end of the shaft 6" and spin it up with the drill.

You will know right away if it is balanced or not.
