Here is what we did to the pin block to reinforce the tuning stability. It didn’t need to be replaced, but we did sure up the tuning pins by 1st, drilling little counter sinks into each tuning pin hole:
Then we reinsert the old tuning pins just slightly and fill those counter sinks with a 2-part epoxy mix:
After it dries we then remove the old tuning pins and sand the epoxy down to the wood. What results (aside from a lot of dust – see dusty arm shots) is a perfect little epoxy ring around each tuning pin that creates massive stability of the original pin block:
As promised…the dusty arm shots. Weird, huh?:
