Layout for spare ball
« on: August 19, 2003, 02:46:24 AM »
I have ordered a plastic Columbia ball for a spare ball.  I am a low speed (13 mph) stroker.  I want the ball to break as little as possible using my normal release (high three quarter roller).  I don't care if it rolls on the finger or thumb holes.  I'm thinking either place both the pin and cg between the grip centerline and the track or place the pin on the pap and the cg as close to grip centerline as possible and drill back to negative side weight.  Any thoughts on these layouts or other, better suggestions?  Thanks.  JohnP

I don't know about Columbia, but my Brunswick spare ball doesn't have a pin. The CG is marked, and the drilling is straight up.

if it is a white dot...dead over the lable is fine.  If not, try to go negative and maybe even move the pin towards the track with the cg in the center.

As others have already said, in general, the drilling of a hard plastic ball should make little difference.

If you wish to minimize the reaction, you can drill it with maximum negative side weight (1 oz) and maximum thumb weight (1 oz) that can be done with that ball. This will make the ball go into a roll as soon as possible and will minimize the hook. Your driller should know how to do this.

pin placement on true pancake core balls such as White Dots and Maxims has no effect. Only the CG movement/placement and subsequent side/finger-thumb/top-bottom weighting has an effect.

It is a white dot, and you are right.  It came in, and the pin (had to look very carefully to find it at all) is on the bottom of the ball.  I'm not going to drill it for a couple of weeks -- I'm changing weights from 16 lb to 14 lb, and don't want to do the spare ball until my new strike ball comes in.  I'm planning to use about 3/4 oz of neg side wt and see what it does.  I'll post results when I've had a chance to get used to it.  Thanks for the input.  -- JohnP
