Reference line
« on: July 20, 2007, 09:39:40 AM »
I don't drill balls, but I'm curious to know how once I have found my PAP location (using a pin to PAP, MB to PAP system) on an undrilled ball, how do I know which direction on the ball to move to find my grip center.  How do I know, out of the infinite options on the sphere, which direction is north, east, south, and west, if you catch my drift.

As well as a "pin above GC" distance, may I also specify a "pin left/right of GC distance?


Re-Evolution is right, you use one or the other but not both as the third dimension required.  But the horizontal dimension is usually specified as distance from the vertical axis line, that's the system Storm uses and calls pin buffer.

As far as distance from a hole to the pin, the warranty varies from manufacturer to manufacturer.  Ebonite and Hammer (and I assume the new Track and Columbia) balls just say don't drill part of the pin out, either miss it completely or drill it all out.  Others say stay an inch away or drill it out completely.  On all the balls I drill I try to keep the pin at least 1/2" away from a hole or drill it out completely.  --  JohnP
