positioning a ball in a spinner

[astroskg]

looking for detailed instructions for the proper way to refinish / change surface of a ball.
i own a ball spinner and have read the instructions but true ball placement is not really mentioned,
other than fingers down, rotate 180 fingers up, then rotate 90 degrees then 180 so all four sides are done
another article i read mentioned 2 more rotations i guess in a 45 degree from the last one not for sure how they make the last two movements?

because of the way the ball rolls down the alley should there be a certain direction the last sanding should be done
so it grips the lane to create drive? or allows the ball to slide a bit further?

should i be more precise in positioning the ball in the spinner and orientate maybe off the pin and not finger holes or thumb hole?

any one know of a book somewhere that explains maybe different patterns of sanding for different reactions? or even the correct way to perform this process.

or do i need to go to some school to learn ball drilling for two days so i can get the 5 minute "This is how you can do it" class

thanks for any help

Find a copy of Revolutions II by Chip Zielke. He describes different sanding methods for bowling balls in this book. There are also a few articles you can find on the web on sanding balls.

Heres a chart that shows the standard 6 sides of a bowling ball and how they look oriented on the spinner.

Heres a page that shows you the different sanding patterns and what they do.

There are a few people that claim a 6 sided turning plan is the right way. I subscribe to 4 sided. I do the four sides you talked about. Remember the 500 grit base coat is the one you want to put good pressure on. The rest of the pads you use, you want to use light pressure. I also don't recommend having a lot of middle steps. I go from 500 to whatever the top coat is. (4000,2000, step 2 polish, etc.)They started to tell people that to finish a 4000 grit ball, you would go 500,1000,2000, then 4000. I find that it not only calms the ball down, but it also doesn't last as long. I find a better reaction going from 500 to 4000 grit.

Ultimately it all depends on what you want to accomplish. Just a cover change or a return to the out of box finish (O.O.B.) or a full resurfacing (meaning the removal of all nicks,gouges etc.).

For just a cover change the 4 side plan is fine. As for what steps in grit, that all depends on what your looking for in regards to reaction. It will be different for everyone.

To go to the O.O.B. You should follow how the mfg. recommends, most ball companies now will tell you how to do it?
For a full resurfacing I would go with the 6 sided plan, at least for the coarsest grit till you get to the base coat. To help maintain roundness if your not using CAB blocks.

This is called skip a grit. Basically whatever finish you want to end with, the second to last step should be 1/4 of that finish (i.e. 1000 - 4000, 500 - 2000, etc.).
