Pin In vs. Pin Out
« on: August 12, 2004, 12:29:22 AM »
This may be a question for the drilling forum, but since I will be purchasing a Bullet, maybe you guys would help me.

I am looking for a ball that has excellent length and arc instead of skid/snap.  I bowl with light oil on wood lanes and have too much hand.

I have read where pin out will give my driller more drill options, will provide length, but will provide snap.  A pin in drill will provide not as many drill options, not as much length, and no snap.  Hopefully that is correct.  If not, school me.

What do you Lane #1 users recommend?

Thanks

Bill

I would probably say a 1" pin with 2.5oz tw.
and drill it 315 with the pin above and between the bridge.

The 315 gives you good length, and putting the pin above the finger will give you even more.

Yes, a pin in ball will roll earlier with less snap. This may be too early..? The Bullet goes long and arcs, no snap.

If you use a ball with more of a pin out, then a CG out drilling will help control the backend, giving you less of a snap.

If you drill the ball with the pin farther from your grip center than the CG is, i.e. label 1:30, the ball will go longer with more finish on the backend.

This ball is smooth, so a drilling with more backend could be beneficial..? =:^D

I use the 315 on an executioner and get very good length.

The 315 is used to take the reaction out of a ball:

Putting the pin above the finger will increase this effect.

If you are going to use a pin out I think a 3-4 pin with low top weight,
drilled 45degs pin above the fingers.(6x5, 5x4 somewhere in there)

You may also want to try a 135 also:
