It also helps if you take a gouge and cut the end of the stock slightly to make it a dished out surface. Lower in the center than the edge by 1/8". As the leather covered pad seats it will flow into the undercut. If you do not do this you can get a gap under the pad. I do this even on non covered pads. Worse thing in the world is having a stock with wood higher in the center than at the edge. No matter how tight you screw it down it will never seat.
