increasing the backend
« on: December 31, 2004, 12:15:39 AM »
I have a amf triumph tnt that I have already drilled out.  It is pin under ring, cg stacked about 2 inches below.  Just slighlty postive.  I drilled this cuz I heard this ball was a monster.  Well it is a great ball but it isnt the monster I thought.  it currently has no wt holes.  Can I use a wt hole to increase the backend reaction of overall hook of this ball.  It does not flare a ton but it is flaring some right now.  I would like to keep the cover the same. thanks

Depending on what your static weights are now you could put a balance hole on the negative side in the thumb quad on your negative axis line. This will add positive side and finger weight which will give the ball a bit more length and flip. I would use a smaller and deeper hole to help increase the RG slightly.

would not a wt hole on the negative side maybe hit the track??  Reading on brunswick drill charts they talk about a flare increasing wt hole that is 2 .25 inches past a line from pin thru pap.  is this what I am looking for??  thanks for your help.

this ball is nowhere near an ultimate inferon I just got.  dont get wrong, I thin I am avg about 225 with the tnt but if there is much carrydown it needs a lillte pop.  the ball is not a monster, even in box.  it is though a great underrated ball.

No, that will increase the flare immediately. A wt hole inside your PAP, closer to the center of the grip will reduce flare, with very slight increase inlength. That may save some energy, but will mostly result in very slightly reduced hook.

A TNT is a very strong ball. If you're a true stroker, very few balls will hook a lot for you. The TNT's purpose is heavy oil; so, it's not a go long ball by any stretch of the imagination. Its stock cover should ALMOST be immune to carrydown. BTW a 225 average is VERY, VERY good by most bowlers' standards.

What I've always done to get more flare on the backend is put a weight hole 1" past my PAP.  Increases top weight.  Or you could drill on your PAP and pitch the hole as much as 1 1/4" away from your grip.  Of course, this depends on how much side weight is actually on the ball.

I think this will work for a pearl or highly polished ball, since it saves energy by skiding a lot further. Thus, the added flare is mostly saved for the backend.

Since, as you move the weight hole past the PAP, it adds flare, and since a dull or matte finish ball, like the TNT, flares immediately, due to friction, the effect should be to start hooking earlier than it would without the weight hole.
