Double Thumb Drilling

Post by trubenchoun »

How would I know whether or not I should be using the 45* or 60* degree layout for Double Thumb Drilling?

What differences would I expect to see from one to the other?

I'm excited, I bought a case of Craze's and I'm gonna tryout a few different drilling layouts.

I am a little confused.

Double thumb drilling is ???x4"x30 (val angle)

Your drilling angle varies on the individual..you have to measure it from an existing ball then that is YOUR drilling angle you add to the ??? part of the equation

PAP : 5 3/4" by 1/2"
Ball Speed: 17 mph (lane average foul -> headpin)
Rev Rate: 405
Tilt: 17 degrees
Rotation: 60 degrees

Thanks for clearing it up for me. Now I won't feel like an oaf for not bringing my existing ball in with me.
