What are the "general" safe PIN to PAP distances for low, medium and high trackers?
I have a customer that has a 5 1/4 by 1/4 up PAP and has a ball with a PIN to PAP of 2 1/4" and is hitting the thumb hole. ( i didnt drill it, just trying to help him )
Thanks,
Tim

Tim,

I use pin to pap distances of 3/4" on the short side to 6 1/4" on the long side no matta what the pap is (as long as it is accurate). I also try to keep pins in the "flare safe zone" by controlling the pin to val angle based on track distance to the fingers... low tracks as low as 70*, medium tracks 60* & high tracks 50* (all tracks 20* to val on the low side).

I find that if the release track hits the thumb hole, it is usually a grip or release issue, not layout. If a subsequent tracks hits the thumb hole, you must make sure the pap is flare safe & not past the val.

If its flare safe and the pap is accurate and it still hits holes on subsequent tracks I send it back defective.

Thanks Ron. Well done. On higher track (lower tilt) players, I try not to use pin to PAP distances in excess of 4 3/4" because it can pull the track up on the holes. It doesn't happen all the time, but it happens often enough for me to avoid it.

Thanks for your input, Mo! I have yet to run into that situation... I will add it to the mental "tool-kit".

To clarify, do you use that same number on "symmetrical" cores as well?
