After the pegs are shaped on the lathe, the round head must be shaped into a flat head so it can be easily turned. I use a reamer with a 1:30 taper for the peg holes. The taper makes the pegs stick enough into the pegbox so that the string won’t slip at full tension. It takes awhile to fit the pegs into the pegbox so that they turn freely without binding and stick out in an aesthetically pleasing way. After the pegs are finished completely, I polish the heads with a coating of beeswax.
