To much side weight on TFD
« on: January 21, 2009, 04:49:55 AM »
Just wondering i got a Twisted fury destruction and it looks like this
    o      pin
   
    x      cg

       mb  mass bias
With this and me being a lefty when i lay it out the cg is far to far over and gives me to much side weight. I'm looking to drill it 65-4 3/4-30 a nice skid snap well the most skid snap u going to get out of Brunswick. Also my driller says i have a pap of 6 1/2 inches is that even possible that is huge? So pretty much what im asking is how would i get rid of excess side weight my best guess was to put a weight hole on my pap but then again that is just me guessing, any real help would be nice.

You may have to get a different ball with a different pin/cg/mb alignment,or alter your layout plans.Layout the ball the way you want and check the side weight on the dodo scale.If the the side weight is over 2 ounces,you must alter the layout until you get it to 2 ounces or less,or you will not be able to get the side weight legal with a legal weight hole.With mb balls,there really are "right" and "left" handed balls now!

There's a limit on the size of a weight hole?

USBC rules limit the size of a weight hole to 1 1/4". Also, if the hole is pitched,it can easily exceed this even if drilled 1 1/4". Because of this, I try to use 1 1/8" or smaller weight holes, if possible!

Having a positive axis point that far over could basically make you a full roller due to the standard measurements of a bowling ball.  Also the static weight can be removed using a balance hole...see Mo Pinel's gradient line balance hole system to use the hole location for maximum effect given the reaction you are looking for...or just draw a line from your center of grip through your cg to your val just to get the weight out.

I agree with Chris here...at 6-1/2" you'd be tracking over the thumb on every shot.....are you sure?

We had a Twisted solid blem in my drillers shop you would have loved!!! Ended up laying it out pin over the fingers for a lefty and we could give him an mb placement near his VAL with no hole needed.
