This is the pin block from the piano tear down I just posted pictures of. It is a rather complex shape with several different levels- beyond my meager woodworking skills to duplicate. I could have used plugs but borrowing from Terry Farrell, I decided to router out the pin fields. I drew boxes around 3 pin field areas- the two in the treble happened to come out so I could make them the same size. I then transferred the dimensions of those boxes to a piece of OSB board. I then drew a box 2.75" bigger all the way around (6" router base, 1/2" cutting bit) and cut out the big box to make my pattern. Since I was able to make the two treble cutouts the same, I only had to make two patterns. Today I am going to a big woodworking shop owned by a friend and I intend to cut out the inserts on a good band saw. I plan on epoxying the inserts into place. I was wondering if scoring the surfaces with a coarse rasp file, instead of leaving them smooth, might give the epoxy better surfaces to bond.
