The most important possession of an instrument maker is his workbench.
Stanley Doubtfire, Make Your Own Classical Guitar, 1981
You know you've gone completely nuts when you take a bone keyboard tail, cut it into three pieces and then glue all the pieces back together again with some added black veneer. I did this to make a veneer overlay for the tie block on one of the guitar bridges I am making.
After I cut the three pieces and super glued on the black veneer, I made a miter box out of a piece of scrap pine.
I've cut many a precise cut when I was a full-time finish/trim carpenter, though I never did any work this small on a custom home. I think these Xacto brand mini back saws are the best!
Testing the cuts as I go.
The end pieces are so small that I had to put everything on a piece of double sided carpet tape.
All the pieces and miter cuts are coming along nicely, though if you have a good eye you can see a piece that was cut just a hair's width too short.
To assemble the overlay, I first tacked the center piece to a sheet of paper with cyanoacrylate glue, then with the help of the wicking action of the black wood veneer I glued each piece into place. It went pretty fast.
The overlay is ready to be glued onto the bridge tie block.
