I've taken an old treadmill apart and still have the DC motor and controller/drive board. I already have a Vertex single speed spinner, but I figured I could make either another variable speed spinner or something else.

It should work out fine if you can figure out the packaging and mounting the motor shaft to a ball bowl. Treadmills usually have DC motors because it's cheaper and easier to cover a full range of speeds versus an AC motor. The DC controller boards usually have a 0-10VDC input which is fed-in from the digital display based on miles/hour selection. If you don't want to use or don't have the display you can replace it with a liner taper 5K potentiometer. Put the wiper leg from the potentiometer on the DC controller board which is usually marked "P2". The outer legs go to "P1" and "P3" which are ground and 10 volts derived on the board from a DC supply. The speed will now be controlled with the potentiometer which should be linear as you turn it up/down.

Looking at all the posts here. If you're into making your own thing, then fine, but can just go to polishyourball.com and look at what they have. You just need any standard drill. Works pretty good for most anything need to do at home.

I just happened to come across this old thread. From looking at their products, I felt it worth a bump.

Everything can fit into a small box, and their products seem to be just common sense.

In my opinion, the only reason to own a ball spinner is to polish a ball, and those things just don't create enough RPMs to shine a ball. They come out looking duller. Just my experience and opinion.

Hello,
Made one it's a 1100 rpm motor garage door opener perfect for me. tried a 3400 rpm motor to way too much. i got the motors for free. constructing the box to support the motor took me a while, the hard part was mounting the metal bowl which i decided to mount a pulley on the motor then use another pulley which the bowl rested on. Drilled holes 4 hole thru the bowl and pulley attached it with 7/16 nuts a bolts. spent a total of 40 dollars.

Hey , I've seen this thread before and was intrigued by this setup. Harbor Freight still has the press and is still a good buy at $50.
Very tempting.

More than likely true. I've been cleaning after every practice and league. I also just started to touch the ball up with an Abralon pad, by hand. Is there a real advantage to Polishing the ball? I tried that a few times last year by hand, and realized it was a losing battle.

Right now after I use the pad, I clean and wipe off, that's about it.

I know this is a three year old thread, but there's a ball spinner currently listed on the large auction site. Ends 7/10/16.

The ball spinner is a Bizmar ball spinner made by Bruce Marberg. It uses a sealed aircraft bearing under the ball cup so it should never wobble. I bought mine from Bruce himself back in 1979 and paid $180 back then.

Looks like a well built ball spinner that holds it value well. Used approaching that 180 mark.

Also the winner has to pay shipping...
