I think you did not get the clue . . . I think it is YOU who is getting the otto 

By the way, if the ball happened to have the 8 on both sides, a slight over polishing could get one to be an S

I broke my first pool ball yesterday.  Perhaps a pin chuck was not such a good idea?

I glued it back together...I'm puttin' the Gorilla to the test!

  Eric thanks for showing us the possibilities! I have made two pool ball tops and the second one came out pretty nice I'll post a picture soon.The first one was a great training tool it's just no longer capable of spinning. I just got a new chuck so I'm having lots of fun in the shop. Thanks for the inspiration.

[poptop]

Yes, thanks for the inspiration Eric! 

Here's mine...not a work of art, but I'm pleased.  I didn't hollow it enough, so I'm going to chop off the wood tip and tweak it some more.  The wood tip, now cracked, was temporary so I could try it out. This ball has a dark grey material in the center that is, well, off-center.  The top has a serious wobble at high speed, then settles down.  At first I thought the COG might be too high, but not really.  Not sure why it wobbles so much unless the grey core material has a different density? 

Oh, yeah, this is the one that cracked in half too.  Gorilla glue wins!

Sweet looking top! 
What wood did you use poptop? 

[Eric]

Great job poptop!!!!
What wood is it?
As for the grey core material, I'm not sure about it.  All of the pool balls that I've used so far were made of the same material throughout.

[poptop]

Thanks guys.  Unfortunately, I'm not sure what kind of wood it is.  It came in a mixed lot of stopper sized hardwood turning squares.  The only hint I had was the initials "BW" were written on the piece I used.  I figured it would likely be bloodwood, but it looks a little different from another bit I also thought to be bloodwood.  I suppose the name is applied to more than one kind of wood.  Its a nice reddish orange, kinda porous like rosewood.

Very nice poptop! I love the wood. Here is what I came up with it has some slight balance issues but does play very well I may try to thin it down a bit, but it is a lot of fun my 8 on the upper dot is totally gone.

That is one slick looking top!
Very cool mtntop!   

[ta0]

Wow! Both poptop's and mtntop's pool tops look great!

This billiard top idea is here to stay.  I want to see  somebody knocking one of these into the pocket of a pool table or doing a combination shot on a billiards table.

Nice turnin' gents!

[Spinningray]

Nice turning guys! Keep up the great work.

Have been thinking more about top balancing. I think the center of mass needs to be as close to the centroid of the top as possible. The top always wants to rotate/orbit around the center of mass. If the the center of mass and the centroid differ, the top will wobble slightly. The more they differ, the more it wobbles. This would explain why squat shapes don't work well.
