AMF RPM Swirl

Post by DrewPeacock »

A friend of mine has acquired 4 of these balls, and is attempting to drill them. Unfortunately, she does not own a DeTerminator, and the CG stamp seems nearly impossible to find. Is there a specific location in the 'Swirl' label stamp that the CG is located in? Thanks for any information!

If you need to find the CG, just put it on the dodo scale weight it you don't need a determinator.

Bowl1820 is correct. However, if she doesn't have access to a dodo scale, if the ball has the AMF insignia the cg is probably there. If not, find the pin and look on the other side of the ball, it's probably in that area. -- JohnP

Are those originals or did they come out with a remake? I had one of those back in the day. I loved it more than I did the RPM solid. I had mine with a 2 1/2" pin to PAP with the cg towards the middle of my span.
