More backend by moving weighthole??
« on: February 20, 2006, 09:41:36 AM »
Centrifugal Mass. It is layed out 3-3/4 x 2-3/4 and the weighthole is 1" in diameter and is 3" deep. My question is...is it possible to get more backend by plugging the current weighthole and moving it? I have included a picture of the ball and have my PAP marked in the picture. I like the ball, but it just lacks in the back.

Thanks for any suggestions you might have.

Tim

Tim,

Go to legendsbowling.com. They have a really great way of showing what a ball will do when the pin, CG or weight hole is in what position. It's well worth marking for future ref.

Good Lock !

Roger, thanks for the link. I'm just looking for some suggestions from drillers of what size and depth of weight hole and where exactly to put it to give me the most backend out of the layout. Lanemasters site gives a good idea, but I wanted more opinions of personal experiences.

Just wondering why you kicked out the cg to make it roll early if you want more back end?

Mass Bias ball...CG don't matter.

Cg or MB doesn't matter much in this case as both are far too close to PAP to get much backend. It's a early roll drilling, with both pin position, CGposition, and MB position.

If you're considering plugging the weight hole, might as well fix the whole thing, ESPECIALLY given his 500 rpm rev rate in his profile. Plug it all and start over.

This ball,as drilled seems to be a waste to such a bowler.

I'd suggest a 4" - 4.5" pin position, 2"-2.5" above midline (balancing 4" PAP and high rev rate) and maybe a 5"-6" MB-PAP position, would give him more backend and possibly a better balanced ball.

I thought it would be a early rolling drill too, but anything above 600 grit dull makes it get a little too much length. Any other ball I have with similar drills start early no matter the surface. So I keep on thinking if its not starting early then it should be saving energy and release more on the back. Not happening. Don't get me wrong, the ball hits and carrys nicely, but I was just expecting it to be a strong ball somewhere on the lane whether at the midlane or back. I may end up plugging the whole thing and redrilling, but I thought I would try moving the weight hole first and see if I can get more out of it.

Stack it at 3 3/8" - 4" and you'll get more movement. I would move the pin up, at least even with the fingers, assuming you're bowling on a ths.
