All finished and ready to be glued to the neck.
Then, I glued it onto the neck. Well, rather I went through an ordeal gluing it to the neck. First I taped over the trussrod and then spread glue onto the neck with my finger. In the process, I ran my finger quickly over one of the locating pins, cutting myself and getting blood into the glue.
Then I spread glue onto the back of the fretboard. I peeled off the tape where the truss rod would go to leave a clean spot with no glue, and then the fretboard tumbled out of my hands and following Murphy's example of buttered bread, it landed glue face down into a pile of sawdust. I quickly grabbed it out of the pile, but since there was now 3 lbs of sawdust attached to the fretboard, it
snapped in half right at the 7th fret.
I quickly scraped both pieces of fretboard, blew out the break, spread glue on the break and fitted it together tightly. It fit and held, so I spread glue over the back of the fretboard, aligned it down to the neck with the alignment pins and started clamping it gently. I wiped some paste wax on the back edge of a box cutter blade and slid it into the 7th fret slot so that when the board was clamped, I could ensure that slot was not lengthened, shortened or crooked, potentially throwing off the measured intonation of the whole fretboard. Those blades are 0.023" wide, so they fit right into the slot. I clamped it all up, crossed my fingers, and for good measure, worked on the mothman for a while.
Here's a detail of the break post sanding/scraping. You can just see it running at an angle from the 7th fret slot towards the 8th.
This morning, I pulled everything out of the clamps, and not surprisingly, the board is no longer perfectly level at the 7th fret. I pulled out my leveling beam, which is an inexpensive 24" aluminum level, taped down some 100 grit and leveled the entire board. This also necessitated a run over the radius again with 120 and 220 before leveling the string paths again with 320. Looking along the edge of the board, you can't really see much, and I think it will disappear when finished.
