On a ball with pin under RF and CG out 1 1/2" to 2" what can be done to raise the differential? I am going to drill a ball with a .040 differential and want to increase it.

Move the pin above the fingers instead of below.

I am thinking about doing that instead of below fingers. Will that help increase the differential in addition to a P3 or P4 hole???

Yes, but I assume you had a reason for putting the pin below the ring finger.
Pin above (smaller VAL angle) will always have a larger RG Differential and intermediate differential than a pin under (larger VAL angle), put it will also have a different ball reaction.

The bowler is more concerned about the changing/increasing of diff to the point of adding weightholes on a ball to increase a number based off the perception of that number then the reaction of the ball. If adding a weighthole to a pin down ball because it increases diff versus factoring in the change in shape of ball reaction why worry about pin up or pin down if the diff is the bigger concern.

Because I don't know that because he didn't say so. Thus the reason I asked. Until he tells us what his priorities are, I won't assume what it might be.

I typically focus on pin to pap distance to control flare and adjust from there not if it is pin up or down. Since this person is not likely to drill the ball and try it out as is to see what kind of flare separation the ball has and instead add a flare increasing weight hole I say so be it.

Ok, we're different there. I focus on both the VAL angle (pin up or pin down ) and the pin-PAP distance.

Most bowlers with two identical bowling balls from a manufacture and if were told one has a diff of .040 and the other .050 if asked if there is a difference in ball reaction the vast majority would say yes.......they do not know any better. Most bowlers will also not see a big difference on ball reaction on most house shots because of the condition. It blends everything out.

I think most bowlers don't know what the difference in the RG differential would mean. Most bowlers who post here probably do.

I think Brickguy would see a difference; he's been here a long time and learned a lot, but who knows for certain until he answers my question.

Get a long pin, go with a 3-3/8 pin, 30 degrees from Val, place the "mb" where it would be on the Val, put hole where mb would be. Bigger the hole, the better. Only care about statics for legality reasons. I had a Threat drilled similar, only I put a hole on my pap because the thing flared a ton and without the hole, was too much off the spot.

Because of my old age and medical condition and my having low revs, balls with lower pins and higher differential work best for me. I don't have "much hand" and need help to get the ball rolling and lower pins with higher differentials do that for me better than higher pins and balls with lower differentials. Lefty 50 and I seem to have similar styles, so he is correct where he said ... "Differential is what helps that engine get the tires moving so they can more effectively be utilized." ... as that is my case and apparently his also.

If that's the case, then a P3 hole will/should raise the differentials, and P4/Double Thumb should maximize them.

Drilling a ball pin down lowers the differential. Drilling a ball pin down makes the ball lope down lane, elongates the hook phase, and delays the ball getting into a roll. Pin down does not mean early roll or getting the tires moving.

Why are you so inclined to go pin down? I would like to understand the reasoning given what is now known about layouts.

Out of all the balls I have drilled over the years, pin down has always worked the best for me, thus the reason I like pin downs. I disagree with you where you said ... "Drilling a ball pin down makes the ball lope down lane, elongates the hook phase, and delays the ball getting into a roll. Pin down does not mean early roll or getting the tires moving." ... as it has worked the opposite of what you said for me, but don't want to discuss further as it would be useless to do so.

I drilled it late today but haven't tried it yet and "went out on a limb" and decided to try a higher pin drilling which has worked for me on a few but not many balls in the past, but hasn't worked for me on more balls than it has worked on. I duplicated a drilling that I had on a Storm Nano Solid and polished. That ball turned out to be a favorite and one of the most versatile balls I have owned. I loved that ball from the first time I threw it. Had I not been forced to drop to 12#, I would still be throwing it.
