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.

The next job was cutting out the soundhole, and after that the more tricky task of cutting a wedge shaped slot into the part of the belly that slopes downwards. In retrospect, I probably should have done this before the two halves of the belly were glued together, but in the end I used a scalpel and a razor blade, and I was reasonably happy with the outcome.
The next stage was bending the front. I first made a groove in the back of the belly that went about two thirds of the way through (leaving a bit less than 1mm of wood). After a bit of experimenting I found it was best to put some water onto the belly at the join, and then apply heat to the front while bending. Once I had the required 15 degree angle I clamped it onto a wedge while it cooled.
The lines on the last photo show the position for two of the three braces.
