Assymetrical balls and core laydown
« on: April 17, 2005, 02:00:41 AM »
Here is another question for you all.

When you have a stronger player with a good match up of speed and rev rate and low axis tilt that does not require help getting the ball into a roll where would you keep the side weight at?

Same question to a player but has high tilt?

Doc, I believe you do or used to bowl with Rick (tenpinspro). Ask him as I'm sure he can answer your question.

Less tilt will usually need more side weight. More tilt, less side weight. =:^D

I am a power player(two handed, albeit)...but my revrate is 510rpms with a speed of about 18-18.4mph(on avg) and a tilt of about 53degrees(All Ebonite Bowlers Map calculations) and when drilling balls whether I have a weighthole or not, I like to keep my static weights around 1/4 positive side and between 1/4 and 1/2 positive finger weight, unless I am looking for a hook/stop type of reaction, then I'll put the weighthole inside of my VAL(outside the VAL usually flares over the hole for me) and reduce the sideweight to 1/2 negative(I've done this in a Red Executioner and Hex Revmaster and they both work great).

Static weights do not matter. Aside from making the ball legal and positioning balance holes it does not matter where you put the CG. This has been proven by Brunswick with Throwbot.

If you are drilling a ball with lots of assymetry in the core then you will need to consider where this 'mass bias' (or PSA, RAD, bomb etc etc etc) is located. As it is approximately in a line with the pin and CG you will then have to consider the CG position, but only as a secondary consideration.

The degree layout system need only be considered for assymetrical balls.
