Plugging a double thumb weight hole
« on: March 19, 2010, 10:04:34 AM »
I have a double thumb layout on a Clutch Pearl I bought on here. The problem is is midlanes more than I'd like killing some backend. I'm assuming the weight hole is the culprit due to the increased asymmetry?? Will plugging this hole help or is it too late due to the core being altered by the weight hole. Obviously I know I'd have to add plug to the middle finger to get it back legal.

I believe the ball will be 2+ ounces of thumb weight two heavy. The drilling calls for a 4.5" pin to pap. I don't know HOW you going to be able to remove that much thumb weight. You will probably need to plug and redrill the ball because that much weight will put the ball into a heavy roll early. I hope that helps. I would also like to hear from other pro shops. The double thumb is a interesting concept that changes the diff Dramatically. the don

For DC
Just curious, how did you come up with over 3 oz total thumb weight after plugging the x hole since you are saying over 2 oz past legal?

All I know is I had the fingers drilled deep, and the ball was 2.5 ounces thumb heavy BEFORE I drilled the weight hole, and drilled the thumb deeper.   PLEASE correct me if I have this wrong.

Too much midlane? The first culprit is the surface...

But, if completely plugging the balance hole creates an issue with statics that can't be solved with adding plug to the other holes, you can -

A) Put a balance hole, if possible, in a location that won't increase the differential as dramatically.

B) Starting at a shallow depth and with a small drill bit in the original location, work the balance hole wider and deeper until you are legal.

Shallow and wide balance holes don't affect core dynamics as much as deep balance holes.
