Effects of a pitched Weight Hole
« on: November 07, 2006, 07:07:54 AM »
Hi all,
I was wondering what the pros/cons and/or benefits are of pitching a weight hole.

Thanks in advance,
BMM

A pitched weight hole is primarily used to re-position the hole to an area that the track won't flare over it. Hole positioning is very specificc when trying to end with the exact static weights you're looking for.

If the hole needs to be placed to an area where the ball will flare over the hole, then you can move the hole an inch or so in the opposite direction, then pitch it accordingly to cut underneath the center of the area it was originally supposed to be drilled at.

That's the primary purpose of pitching weight holes. =:^D

Pitching weight holes creates an instability in the ball and dramatically enhances the flare.  Mo Pinel recommends a weight hole 1-1/4"(I think) away from the PAP pitched 1-1/4" away(I'm sure of this one) from the PAP essentially revolving around the PAP.  I would not recommend doing this unless you are in dire need of flare (clipping hole and such).  A high rev players throwing a high flare ball with a high flare drilling and one of these holes can flare around the entire ball!

Mo additional layouts says to pitch the balance hole 1-1/4" away fromt he center of the grip, not the PAP.  Sorry, I was mistaken earlier or I misunderstood him last year.

Just as you could pitch a thumbhole, so could the weighthole be pitched.

Pitching the weighthole away from the palm preserved more top weight in the ball thus enhancing the backend and the hit of the ball.

Pitching the hole towards the palm caused the ball to lose more topweight and thus making a smoother reaction.

Pitching towards the thumb will cause more length and a sharper backend reaction. Pitching towards the fingers will have an opposite effect.

The current way of thinking if you are strictly worried about getting the ball back within the legal ABC limits is to place the weighthole at the intersection of a line drawn from the grip center, through the CG to the vertical axis line. A hole placed here will stand a 95% chance of getting the ball back within the limits.

anywhere on that line from grip center to VAL through the CG?

i find that hard to believe.

where did you get 95% from?

i have a 3.9 ounce top weight ball with the cg about 2 inches over and 2 inches down from grip center, if i make an x-hole in the thumb quandrant 1" x 2.5" on a line through the CG to the grip center then there is a good chance that this ball will make it back under 1 ounce side and thumb?

 Obviously your scenario would not fall within the 95%. And I am ssuming that there wil be a flood of such posts coming soon. The idea is not to sit there and think of scenarios that would not meet the criteria, but to think of all the balls out there that use standard layout methods. This was published a few years back by Mo.

As Greg T said, draw a line from the grip center through the cg and drill the balance hole where that line intersects the VAL.  Of course, you still have to figure what size and depth of hole to use to make the ball legal.  --  JohnP

no kidding, its a realistic situation, in fact, im going to drill an illegal ball due to the offset placement of the CG on an asymmetric ball.

dunno, I'm personally not going to drill it, its for my dad for christmas, my ball driller has a DODO scale, he'll have to check it, it may end up being illegal, but who's going to check?

  But, if you pitch the hole towards the fingers and away from the palm it would probably work. Just as the instructions say.
