A very small offset (don't remember how much, maybe 1/16"?) of the core from center causes the cg to shift away from the pin. -- JohnP

can they repeat this offset at will because balls with 4-5 pin help me when I need to drill a p3 o4 hole because my pap is 4- 1/2 x 1-1/2 up and these balls are hard to come by some times
