[Joe & Penny Goss]

Doug,
Perhaps the list is so long due to the fact that one must do some over

Add string leveling with my level<G>
Hammer flange bushing friction
Front rail friction
Balance rail friction
termination point seating
tuning pin adjustment
hammer to string mateing
only ten to go <G>
