Made this up for the rotor on my MTD chipper/shredder. It's had a vibration ever since I bought it several yrs ago. Enough so it was cracking some of the sheet metal. I had my local machine shop make up the stub shaft with a 3/8"x 16 hole in the end and ordered 3/8" and 1" ball bearings. Rotated it slowly to let it stop several times with the light side on top and started adding weld to that side until it will stop at random points which tells me it's static balanced. Now in a few weeks I'll find out if it's dynamic balanced. Took quite a bit of .023 wire as you can see by the pic. I had to wire all the hammers out to their in operation position for balancing purposes.
