Polishing theory - please advise
« on: August 09, 2007, 12:32:52 AM »
I need some opinions on this:

I have two Strike Zones (well, 3), and I have been trying to polish two of them and make one go longer than the other.

SZ#1 is at 800-grit (grey Scotch Brite)
SZ#2 is at 2000-grit (wet-sanded, stepped up from 400 starting off)
Both polished with Brunswick High Gloss Factory Finish

I love SZ#1, and have been using it polished, and it makes a violent left turn down the lanes, good for medium conditions. But I cannot for the life of me understand why it goes longer than the 2000-grit SZ!

My goal was to make the 2nd one go longer than the first, with less snap- for dryer lanes.  What I got out of the 2nd one though was a long arc, much like the original Strike Zone reaction, but more tame. It doesn't even go as long as the first one!?!?!

Please explain to me why (not).

My theory is that with a lower grit ball, there's more polish in the surface pits than with a higher grit ball, making the ball skid longer and, when it finally grabs, has lots more stored energy- thus snapping harder.

I know I could be wrong, I just wanted to hear your opinions. Please help.

I'm editing what I just said...
Upon further review (I was waaay wrong), for the 800-grit I have the pin 1.5 inches under my ring finger, Cg 2 inches from the pin 45 degrees down to the right, with a small balance whole making a perfect triangle with the ring finger and thumb.
For the 2000-grit, the pin is one inch away from ring to the right, and CG out about an inch, there is a small balance holes about 4 inches away from the thumb.

Where is the MB on the second SZ?

FYI A highly polished ball has a much quicker response time to friction than a ball with more surface.

On SZ#1 the MB is in line with the pin and CG, down and to the right around 45 dgrees.
On SZ#2 the MB is also in line with the pin and CG, recall that the pin is next to the ring finger by 1", and the CG is down to the righ a little.  The MB is around 3 inches away from the thumb to the right.

I hope this helps (I'm not good at this):
SZ#1

O--O
----p
-------g
------------x
--O--------M


SZ#2

O--O--p
     
---------g
------------x
--O-------M

does this hlp at all?

Longer pin to pap distances produce a later breakpoint which is exactly how your two balls compare. The longer pin does go longer and the shorter pin rolls earlier. The flare rings on SZ #2 could also be 3/8" apart or more causing early roll as well.

You need to find your PAP coordinates to determine how long these pins really are.
