high track/pin under drilling
« on: December 03, 2005, 11:35:59 PM »
i'm  a high track and clip the thumbhole with the first ring of flare with pin-up drillings. b/c of this, it kind of counts me out for pin under drillings, which i hit at least half way into the thumb with the first ring. what i'm wondering is if i put the pin under the middle finger, would it avoid the thumb a little more? lmk.

Hmm... holes in the positive thumb quadrant move the bowtie up, but i'm not sure moving it up would help move the track off your thumb.

I think a hole would move it off your thumb, I'm just not certain were it would need to be placed.

anyone else? i really feel like i'm missing out on some great layouts not being able to use any pin below drillings-what if i put the pin even a touch left of my middle finger below it? lmk.

anyone know about where i would put an x hole to move my track off my thumb?

As you move the pin towards the track, the first ring of the track moves closer, not further away.

If a ball's core has a high enough RG differential, say over .040, then a hole 2 1/2" - 3 1/2" below your PAP usually will raise the bowtie enough so that a high tracker will not hit the finger holes. No guarantees, but that's the way it usually works. Your driller should be familiar with this. So if you have a 3-4" pin-CG ball, and the CG winds up in the thumb positive quadrant, the "normal" weight hole is place, measuring from center of grip through the CG to a distance at least equivalent to your PAP measurement. This will generally put the weight hole somewhere below the PAP. As I said, your driller should be familiar with this idea
