Title: switch grip drilling-how much weight removal?
Post by: 1fife on March 18, 2013, 09:31:13 PM

Got to thinking

How much weight do you think is removed when drilling the 1 1/2 hole when installing a turbo switch grip?

You worried your stuff may start to way 12lbs?

Check the bowlingchat.net wiki and click on the weight removal chart. That will let you know the weight being removed and at what depths

FWIW - A 1.5" hole removes 125% more material than a 1" hole of the equivalent depth.  I'd be more worried about diminished core dynamics at that size and depth.  It's likely not on the Jayhawk chart since it's illegal to use a hole larger than 1.25" for balance purposes.

Static weight has little to no effect on overall ball reaction.

Also - I reviewed the USBC Equip. and Spec. manual and it's illegal to deliver a ball without the inner assembly locked in place or to drill the pilot hole for the outer assembly deeper than the installed outer assembly.
