Actually it must have been my eyes playing tricks, so it's time for the mega photo update. So where were we?...
The fretboard inlay was a bit of a sod to scribe around. The headstock inlays were even more intricate, and being full thickness would have been nigh on impossible. So after a few test routes over the past few months I settled on printing an address label with the design on it to use as a guide. Early attempts made me realise that the inlays had been cut by hand, so the original artwork wasn't going to be much use.
I arranged the letters on top of a print of the artwork to get the alignment and spacing correct. Then a strip of masking tape to hold them together and onto the scanner to suck the actual inlay shapes back into the computer. A bit of techno wizardry later, including adding a thin border (the red bit), I had something I could print on a label to stick in place
Taking the trusty Dremel with Stewmac router base and a nifty 1mm end mill bit, I set about it
Plunge cuts were much easier to do than actual lateral routing, so a series of those followed by a few router passes got it somewhere close.
I then spent some time fettling each letter: test fitting, wobbling it about and nipping bits off by eye until it fitted snuggly
Eventually we were ready to glue, so I mixed up some epoxy and added ebony dust to make a paste. Old credit/gift cards are really useful. I trimmed a sliver down to a point so I could get glue in all the nooks and crannies, spread the glue and pressed in the inlays with another strip of plastic
Finally I scraped away the excess squeeze out
