Tuning Pin Bushings

[Joseph Garrett]

On a grand I'm rebuilding the old tuning pin bushings
were .41 od but I am unable to find a new set that is
anything smaller than about .44 od.

Would you just not put in bushings on this one, or do
you have a quick method of reducing the size of the
bigger bushings?


Just soak them in a mixture of Synthetic Reducer and pin driving fluid, until they sink to the bottom of the container. This makes them very pliable and also makes them impervious to splitting. Also, they will not lose their "grip" on the tuning pin. Been doing it for years. Oh, mix 50:1, (That's 50 parts S.R. & 1 part pindriving fluid.
