I tried using the washer as a ball spinner. DOESNT WORK! Its got enough to spin the ball, but its not stable enough. The ball flew off, I thought I broke it! Oh well, just a peice that clips back in. It might work if you hold the ball on both sides with whatever your doing, but besides that, no way. (I.E. holding a piece of sandpaper on each side to hold it stable)

And why would I "saw" pins in half, THATS A WASTE OF PINS!

LMAO....you're too much BK, risking a $400+ washer or ruining a $200 ball over a $5 polish at your shop?  C'mon dude, you gotta be "kid"ding me....lol.  I'll give you an "A" for ingenuity though but this is a little overboard.

ROTFLMAO

You could try welding a steel bowl onto the flywheel of your lawn mower
that would be more stable and plenty of power.
Just kidding but I had to give you a hard time somehow.

Maybe you could try Bamaster's idea, this way you won't have to duck from bowling balls zinging by your head like Ninja darts...lol.
