Balance hole question
« on: August 13, 2003, 06:56:27 AM »
currently have a rotogrip pure fuel.
drilled pin 4 1/2 to pap under finger hole.
and MB on VAL..

ended with 7/8oz thumb and 7/8 side weight...

where should i put the weight hole if i want the ball to rev up more in the mid lane without losing power in the backend ?

and also the size and depth..

thanks .

Example of 3/2.

= 3/4 top weight, 1/2 sideweight.

To place ending cg in a leverage position approx 3 3/8 from ones pap.

This gives a reaction that is very strong and hard hitting.

Other ending cgs and characteristics are axis weight, smooth and even.
Grip center is early and snappy.
Negative = early and archy
Bottom weight and side = even and early.


REgards,

Summary, top, side and finger enhance reaction.
Bottom, negative side and thumb = reaction is earlier and more even.

Constantine, I would tend to agree with your reply. I'm guesstimating he doesn't have much, if any top weight left in the ball. With your hole placement recommendation, the decrease in side weight, coupled with a slight increase in top weight, will get you closer to a 3 to 2 ratio top to side weight. This puts the ending CG/heavy spot close to the leverage position, which increase flare and improving your midlane and backend reaction.

What I'd be concerned with is if you kept going bigger and deeper with the hole. This will now take out all the side weight, even going to negative side, and pushes the ending heavy spot/CG towards your track. With the ending CG in/close to your track, the ball will start to react like having your pin in your track, thus decreasing your ball reaction.

You can't just keep drilling bigger and deeper, and expect the reaction to keep getting stronger.

What do you think Const..? =:^D


T-GOD,,how big and deep do you suggest to start with ??

a line from pin through your PAP and put the hole on that line 2.5" outside your VAL.


i'm not sure will that location increase the top weight from the lower part of the ball .~

isn't that if i can get a 3:2 top to side ratio using a weight hole, i can shift the ending CG to a strong leverage position ?

Chun, ending weights and the ending CG are one in the same. I prefer to use a deep hole with a small bit. =:^D
