asura,
That must be the world's most expensive spinner. If you check websites on spinners you'll find their bowl speed is around 4 - 600 rpm. More than that the ball will fly off. Remember the ball have inbalance built in.

You must be in asia or England to use 220 V 50hz. single phase

My homemade one uses pulleys and belt to reduce the drum rpm to 500. Ideal after some experimenting.

Go look around the junk shops for a working fractional hp motor. You can get one for under $10.00.

Message me with your email address and I'll send you picts. of mine.

Wonderful idea Dizzy, Creative to boot!  

Puts a new twist on the term jerry-rig
but this one was well thought out. "Wacko ball spinner", lol

I just love creative ideas; and using the old noggin for a purpose.

Now, I've got this old variable speed electric drill, hmmmmmm!

I "built" one from an electronic power drill with 1hp power. Ball cup is self made from a flower pot (blue) and a PVC water pipe end cap (grey, makes also a nice and cheap ball cup) as a water protection.

The drill has 2 gears and a reverse, and I use it on lowest forward gear with about 1.100 RPM, while speed can be controlled manually.

The heart of the whole thing is the sturdy drill mount, the silver thing at the base. Without it, vibrations etc. would not allow a stable work and I'd call it insecure. But for a spinner tour every now and then, it is O.K.

A pic of V1.0 (idea prototype): http://www.putfile.com/pic.php?img=4170407

Current V2.0 has a more rigid workbench base and a vinyl sheet covering everything except the drill's axis with the ball cup.
