Anchor aweigh!
« on: December 02, 2005, 02:51:00 AM »
I'm hoping someone here that enjoys a challenge can offer some suggestions on drilling a boat anchor.

I have NIB Original Black Hammer with only 1/2oz. top weight.  To make matters worse, the cg is marked exactly 6 3/4" from the pin.  I had the ball spun and the MB is maybe 1 1/2" right of the marked cg.  MB = cg here?

Any layout suggestions from the drill gods?  I have medium/slow ball speed (aroung 14mph on Quibica), medium axis tilt (!9 degrees more or less) and 40 degrees or so rotation.  PAP is 5 1/4 right and up 3/8.

My thought was to drill the thumb hole right through the cg, but I'm not sure what that would do the weight distribution.  Any thoughts?

Are you absolutely sure it only has 1/2 oz of top weight?  If it hasn't been weighed, get it checked.  If the 1/2 oz is correct, any way you drill it it's going to end up with bottom weight.  The original Black Hammer had a core that was only slightly stronger than a pancake core.  I would just place the cg near the grip center and not worry about pin placement.  There were thousands of them drilled that way when they were the hottest ball on the market.  It will probably end up with about 2 oz of bottom weight.  --  JohnP
