Anyone have a homemade ball spinner?

My knowledge of motors is close to zero, so I would be more likely to lose a limb before finding something that worked.

However, I'm kicking around a "proof of concept" ball scale. So far $30 in parts for a digital scale. I figure a little bit of lumber to act as a lever, some formulas into a spread sheet and I can use it to find gross, top, side & finger weights.

I would be careful using wood, you run the risk of possible changes to the wood parts over time that might affect the accuracy. Do to possible drying or moisture absorption of the wood , like weight changes and warping of the parts.

Yeah, thats why it would just be a proof of concept, rather than the final product.

Also, unless the weight of the wood changes in the middle of the weighing, it wouldn't be a problem since the scale is zero'ed out (tare) to eliminate the current weight of the wood and measure only the ball in it's multiple positions.

You guys are crazy. Keep it up!

A few things to keep in mind...
- You want to use a motor with good torque. You wouldn't want the motor to slow down too much when you apply pressure when sanding.
- Make sure the unit is VERY STURDY. When sanding, I sand the ball on 6 sides, which require the turning the ball, which will place the position of the weight block in different positions. Even with my Innovative ball spinner, which is built in a cabinet, it will still wobble a bit depending on the ball and it's weight block
- You would prefer the motor to be protected by water damage. It's best to use a wet sanding method, so the pads don't wear out that easy.

im building mine similar to this except mine is made out of wood and im building an enclosure around the motor
