This layout works best if you start with a 4 to 5 pin, but 3 to 4 is also doable. Instead of putting the pin at 7:30, put it at 1:30, 10 1/8 inches from the center of grip. Drill the balance hole half way between the pin and the VAL. I found that this drilling works best with a tall symmetric core. Another possiblity is to put the pin in the track in the 4:30 position. This creates an even non-flaring roll.
