    Oakley? What are the bushings made of, plastic? Does the tuning pin press inside of the sound board, and press hard on the bushing, too? Donna Chassis

      Thank you! It was a lot of work and I'm excited that I had the opportunity to try!

    Should had angled your jig first for the initial cut it would had saved you much time. There are books out there detailing the procedure. Join the PTG and get some instruction.

    Your piano will not stay in tune. You need a better contact . Really the cut should have been made with a band saw set at the proper angle. Live and learn.

      Thanks for the heads up. Is your suggestion that I should have used a band saw to carve/cut the curve rather than a chisel to get the back curve of the pin block? Or a different spot of the pin block?

      @@oakleydoeseverything6438 What concerns me is the gaps you have. The pinblock is under tons of pressure and the block will flex if not sitting perfectly against the plate. We cut our blocks with a band saw to obtain as close a fit ( angle and size) as possible then we use black graphite powder to see how the fit is. Adjustment is done with a pneumatic rotary rasp. We shoot for a 90% contact. I have heard of people using a filler and clamping to get 100%. Wish you lots of good luck, it is a passion to rebuild pianos :)

      @@oakleydoeseverything6438 don't forget tuning will not be stable until you do it a few times.verify your torque on the pins ,do not screw them in ,hammer them in.(min 75 inch lbs unscrewing,more is better)
