Title: drilling terminology
Post by: skevr on June 29, 2005, 03:22:12 PM

I was wondering what is meant by stacked leverage? and what effect does it have on a bowling ball ( does it hook more ?)

skevr -- Any leverage layout has the pin located 3 3/8" from the PAP.  The stacked version also has the cg or mass bias located 3 3/8" from the PAP.  This layout provides maximum flare and kicks the cg out far enough (for most PAP locations) to allow a balance hole to be used to fine tune the reaction.  --  JohnP
