[pianotech] First Pinblock

Yes, good idea. However, before that, establish whether the original positioning was good! If not, here's your perfect chance to improve it. Copy the good ones and improve those that may have had strings binding on the pins, etc..

By the looks of things, you're beyond that repair scenario, and will be looking at a total replacement of the pinblock, complicated by the excessive goop which will need to be completely removed from the back bracing before replacement may commence.

You'll need to make a paper pattern, using contractor's or butcher paper (not several sheets of computer paper taped together!). Remove the old pins (noting the angle at which they're drilled) and cover the entire pinblock with your paper. Crease the paper along the sides and clearly mark the position with tack marks for later positioning. Use a pencil to make a rubbing of the tuning pin holes. For photos of the technique, have a look at the March, 2011 segment of the "Small Shop" series.
