Title: Drilling thumb thru MB
Post by: Skip H on October 17, 2011, 09:56:11 PM

Does anyone see a problem with drilling the thumb thru the Mass Bias?  In particular with the Mission 2.0?

I do not see a problem with this.  I have a few balls where the MB is in the thumb.  This gives you a weaker MB position, but should not hurt the ball.

Chris,

 

Thanks.  Looking to try to get the ball to start up later without burning up as early.

 From what remember from storm drilling guides..they talk about drilling through the MB.  It says something about enhancing ball motion.  Everytime I have drilled out the MB (only twice) the ball seemed like I lessened the ball motion.  Good luck.  I had a used 2.0 but drilled to go early and was garbage...yours will be awesome as long as its the complete opposite of mine!

Don't throw strikes, throw BOLTS!

Thanks Bill.  I kinda remember the same thing from Storm as well.  I don't think I have ever read anything from Mo Pinel about it.  I wonder what Mo would think.

Actually, drilling out the Mass Bias in any hole will increase the intermediate differential, thus giving more reaction than before. If you look at the 3rd asymmetrical layout of this page:

 

 http://wiki.bowlingchat.net/wiki/images/4/4a/Gradient_Line_Hand_Out.pdf

 

it shows that the undrilled bowling ball starting at .015 intermediate differential and .048 total diff is then increased to .026 and .055. Way stronger in motion than once before. Evidence of putting the preferred spin axis or mass bias near in the thumb hole increases motion, is also found in the symmetrical ball layout on that page when the undrilled ball starts at nearly zero intermediate differential and .054 total diff is increased to .013 int and .061 total. Way stronger in comparison.

Nice resource.  I hadn't seen that one before.  Thanks.
