Aye well. Last week I had a gut upset one evening and was utterly knackered the next day but pressed on with my current guitar build: I marked out & cut the fret-slots in a fretboard then went happily ahead and put the frets in then dressed the ends, which is a bloody fiddly process - the wood between frets has to be protected with masking tape and each fret gets its ends first shaped with a special file then polished with micromesh. I did all this diligently and contentedly, and was quite chuffed with the finished article.
That's when I realized that I should have glued the damn thing to the neck after slotting and before fretting, because you always make fretboard a fraction wider than the neck and take it down flush after gluing.
As a result I had to wrench two frets out to put in locating pins so that it wouldn't shift during clamping, which caused minor splintering around the slots. Clamping itself involved putting cauls between the frets and using every clamp in the shop instead of just half a dozen on to nice big cauls. Once the glue had cured I couldn't plane down the edge but had to take it - and my nicely-dressed frets - down with a great big bastard file instead, then mask off the wood, dress & polish the fret-ends all over again, then take care of the splintering that remained visible once the two frets were back in.
Had to work through the weekend instead of cycling. Knackered today, but I've got to press on...
