Todays Chapter: Final Assembly.
I had a fair amount of filling and filing to do to refit the fifth-string peg into place. This is ordinarily a friction fit. The existing hole was so worn that the splines on the peg shaft would not grip anymore, so I built up the inner surface with epoxy and wood dust, used an old peg for a mold, and let the stuff cure around it. The peg pressed right in and snugged tight.
The neck of a dowel-stick banjo is kind of a neck-through design... the way it is secured is very simple. There are two wooden wedges that are tapped in between this brass retainer that is screwed to the stick, and there is an endbolt that threads into the end of the stick, through the wall of the hoop. This endbolt also acts as a mount bracket for the tailpiece. I tried to picture each part of this mechanism.
Finally, strings. Per customer request, I strung this one with nylon classical strings... which requires a slipknot to be looped around a post on the tailpiece then held as the string is tightened around each peg. (yeah, it's incredibly tedious...)
All done. It really turned out nice. I'll return it to the store in a couple days, after the strings are done stretching out.
