Clatara-"You'd better use Abralon or Siaair always with water and not dry."

Mo-"That eliminates doing it by hand."

Which is why you don't use Abralon Pads by hand kiddies!

Sand 4 ways thoroughly with the first grit and sand two ways quickly with the second grit to do the "skip a grit" procedure.

Stretching spans tends to decrease tilt as does reverse in the fingers.

Reply to a two handed bowler who was clipping the edge of his thumb hole, from viewtopic.php?f=7&t=4798" onclick="window.open(this.href);return false;

Stop chasing your tail! Let's adjust your finger pitches since you don't use your thumb. Drill your fingers 7/16" left by 1/4" forward on your middle finger and 7/16" right by 3/8" reverse on your ring finger, if you're right handed. Now measure your initial axis tilt and your PAP and post that info. We'll go from there. No more hand grenades at 20 paces! Use your normal thumb hole location.

Why is it that Mo doesn't recommend pin to pap distances of anything past 5.5 ?

Here's the real reason. The low RG axis can move when the ball is drilled. Using a pin to PAP distance of > 5.5" might result in the real low RG axis moving to a pin to PAP distance > 6 3/4". That may cause the ball to flare in bad places, causing the ball to flare over some drilling holes. NOT GOOD!

I'll try to make this plain. All balls are delivered with more axis rotation than tilt. Cannot be any other way. The laws of physics dictate that. The ball loses both rotation and tilt. The ball loses rotation faster than it loses tilt until tilt = rotation. That occurs at the second transition. FACT! During the roll phase (after the second transition) the ball loses rotation and tilt at the same rate until the ball hits the pins. That should keep your mind busy for a while.

Phasing is a function of porosity. Change in temperature causes it to absorb moisture. I light wipe with a little acetone, or a hair dryer will get rid of it. BALLS THAT PHASE EASILY HOOK!

From:

This is what a vast majority of low tilt players don't understand. This is the magic. Fingers on the inside hemisphere of the ball at the top of the swing. Fingers move across the back of the ball until the hand reaches the "Nike Swoosh" position at the end of the follow thru. If the wrist is cupped at the top of the swing, it MUST be unloaded by the time of the release.

The reason we use a higher angle ratio for symmetrical balls is that drilled symmetrical balls lose tilt at a rate almost double the rate that asymmetrical balls lose tilt as both types of balls go down the lane.

You're very close. With a symmetrical ball, the PSA will be very near the thumb hole after drilling until the balance hole is drilled. We can change the mass properties of the drilled ball about 40% with layout and balance hole. With an asymmetrical ball, we can put the PSA whereever we want, and change the mass properties of the drilled ball by as much as 84% with layout and balance hole.

Conclusion: Syms are easier to drill and less versatile, making ball selection a premium. Asyms are more versatile and can provide stronger motion, but are dependent on the skills of the ball driller because they are more sensitive to the layout and balance hole.

The higher the diff. ratio, the more the ball displays gyroscopic properties because the PSA is stronger with a higher diff. ratio. In fact, that will help it retain tilt longer. I've been measuring it for years and syms lose tilt about twice as fast as stronger asyms.

The ability of the ball to retain tilt is related to the strength of its' PSA.

Blueprint has done a great service here. the difference is instantaneous direction as opposed to a fixed point rotation is measured against. Since the bulk of my research is from a fixed camera position, this difference can occur. Very educational!

Axis tilt is in relation to the horizon, so it's the same in either system. True "roll out" occurs when the ball has 0* instantaneous axis rotation and 0* of axis tilt. Using Blueprint's system of measuring axis rotation, a ball stops hooking when the instantaneous axis rotation is 0*, the second transition! the ball will have effective hitting power as long as it still has axis tilt. The ball stops hitting when axis tilt reaches 0*.

Good work, Blueprint!

Q. Just wondering if using p3 and p4 balance holes for low tilt players could cause the ball to lose tilt too quickly because of the increase in differential/flare, the same way as using max flare pin postions does. Should there be any concerns? Thanks.

A. Unless they're strongly speed dominant, be cautious with strong balance holes for low tilt bowlers.

With a high track, I wouldn't have drilled equal drilling and VAL angles. Not Good! Most importantly, don't use pin to PAP distances > 4 3/4".

talking about skip a grit viewtopic.php?f=13&t=4987" onclick="window.open(this.href);return false;

We're trying to achieve scratches of alternating depths. 360 should be followed by light 1000. The rule of thumb should be the second grit # cannot exceed 4 times the initial grit number for this to work properly. Examples are 240/light 800; 360/light 1000; 500/light 1500 or 2000; 1000/light 3000 or 4000.

Keeping his head steady, over the little toe on his right foot (if he's right handed), during the approach will make his walk more consistent in direction.


KEEP YOUR HEAD STEADY (WHERE I SAID) DURING THE APPROACH (ABOVE THE LITTLE TOE ON YOUR PUSH OFF FOOT), AND YOUR FEET WILL GO WHERE THEY SHOULD BASED ON YOUR PHYSIOLOGY, AS LONG AS YOU STAY BALANCED.

If you don't put yout feet under your head, you'll fall down.

This one is from Elgavichon, from: viewtopic.php?f=15&t=4992" onclick="window.open(this.href);return false;

The PSA on symmetrical cored ball without a balance hole ends up 6 3/4" from the low RG axis (primary pin), within 1/2" of the centerline of the grip.
