Large Drilling Angles past thumb?
« on: March 02, 2010, 02:09:45 PM »
Hi, it seems to me that high pins above the fingers with a large drill angle would place the MB far into the track for RH players. Is this right? I don't see too many people using angles larger than 55 degrees, and was just curious about it. Personally, my axis is about 3.75" over and 1.25" up. For pin downs, 90 degree drilling angles would place the MB almost in line with the thumb. But for any pin higher than the fingers, the MB would be very far left. Question is, would placing the MB that far left, even though its within the 90 degree max recommended by Mo, still roll alright? Anyone try something like that?

I'm about to drill my second LevRG, and the first one is drilled about 40x3.75x50, and rolls very strong. I want the second to be a longer, higher pin, with maybe a larger drill angle to help it downlane. But for my axis, and desired pin height, it seems the max drill angle I could use would be 55-60 before getting into the negative side of the thumb. Again, any thoughts?

When you have spiritual issues ask a priest.
When you have car troubles ask a mechanic.
When you have health issues ask a doctor.
When you have drilling uncertainties with MoRich balls ask Mo!

I would ask Mo. That is good advice. I have several balls drilled with the mb to the left of my thumb. they go long. great for dry lanes.I get great carry with them on dry lanes. No hook on oil.

Based on your PAP, that should be just fine as long as the angles are correct.  It's not how the layout looks, but whose PAP its based on.

First be sure your PAP location is correct.  Mark the location with a piece of white tape about 1" x 1" on a non-flaring ball and throw it.  The tape should be a white dot stationary on the ball.  If it's not, move the tape around until you find the correct PAP.  The reason I'm doubting the location is that the track for your PAP location should be quite a bit left of the thumb hole, but you're describing mb locations just left of the thumb hole as being in your track.  --  JohnP

This is what 90* m/b placements look like for me. 3 1/2> x 1^ PAP
Use an armadillo to get your PAP,accurately.
Rolls fine. Looks different.
