Mistakes

I'm sure that everyone makes them, but here's my latest one. When I measured the tuning machines to find the correct spacing for the holes in the peghead I was 1mm too short. This was down to the metal plate being slightly bowed and I foolishly measured at the ends of the rollers and not at the base where they join the plate. I went ahead and drilled the first set of four holes before I realised my error and the final hole ended up 3mm out of position.

To fix the problem I glued a circular offcut of peghead veneer to the end of an 8mm wooden dowel and used superglue to fix it into the wrongly positioned hole. The pegheead veneer was left a little proud and scraped flat when the glue was set. The other end or the dowel was sawn flush with the rear (the endgrain will be hidden by the tuning machine plate).

Finally, I redrilled the holes (using a jig with the correct spacing), and the final result is not too bad. Most of the repair will be hidden by the tuning machine bushing, in any case. I made a better job of the second set on the left.
