About this 3D model
This object was made in Tinkercad. https://www.tinkercad.com/things/lHxzFvFGlsa UC207-22 1-3/8in Bearing - $7.50-$22 The weights are cut off from a 2in steel rod stock and need to be .746 inch thick. Contact your local machine shop if you aren't able to make your own, my guy gave them to me for free. It's a tight fit, so use a rubber mallet to force it all together.
