I use screws long enough that the heads don't need to go through the rubber to hold the pad in the jig and large diameter fender washers that sit just snug enough on the surface of the pad.

When installing the regular screws to the stock, some lube on the heads and a small slit in the pad will result in a nearly invisible mark.

But I'm not a pro GS, just an amateur.

Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery? Forbid it Almighty God! I know not what course others may take, but as for me, give me liberty of give me death! P. Henry

Deus vult!
