BW drill sheet.
« on: October 28, 2006, 03:22:09 PM »
I was looking at the BW drilling sheet that comes with the ball.  It says if a balance hole is needed place it 4" right of grip center.  I always thought that balance holes inside of the VAL was for reducing the flare on the ball?

Next, the drill sheet talks about MB placement in terms of degrees.  The sheet shows the skid snap layout with the MB at 45 degrees.  Yet the back of the sheet says MB's at 45 degrees produce a strong arc not flip.  The flip MB on the drill sheet says 75 degrees.  I always have thought that a flip reaction came from MB placements of 75 degress not 45.  I always thought that the further right the MB goes the earlier the roll.  

I just find this kind of confusing.

Well I picked up my BW today.  I was kind of limited because my pro shop guy only had two left at 15lbs.  Both balls had the cg off set to the right.  So the layout I wanted needed a balance hole which I didn't want.  So I drilled it with one anyways, otherwise I would have had to put the MB on the thumb hole.  I was afraid this would put the MB in a tame spot.  I want this ball to backend so i kicked it out 1" right of thumb.  I know this doesn't sound like much but 1" can make a big difference in ball motion when it comes to MB'S.

I put the pin above the bridge( 5.5" from pap) and the MB about 1" right of thumb.  This required a small balance hole.  I had the pro shop guy place the x-hole 4.5" right of the grip center line.  This is just inside of my VAL.  I have never used a balance hole inside my VAL but figured this is what the drill sheet said.  I do know that if I put a balance hole past my VAL I will flare over it.  So hopefully this will work out for me.

I will let everyone know how it workes out in my league tomorrow.

sounds pretty much the same of how mine is drilled buddy. Just my cg wasnt kicked out that bad. If I remember I will take a pic on thurs and send it to you to compare. Good luck and hope this one works out better then the last one.

On a side note chitown I bowled with a guy tonight with med revs to lower revs and med speed , he was using his new No Mercy and let me say WOW it moves!
