Step 2: Neck
This part of the violin is quite tricky to get right. I would recommend finding an old bit of wood to practice on. Harder wood is better as it is easier to carve without large 'chunks' coming off. Softer woods can split easily and this can make the carving process harder. When I did mine I did two practices before starting on the maple. It makes it a lot easier to figure out what order you need to do things in.
Here are the basic steps I followed:
1. Cut the side view out using a band saw (easiest option)
2. Drill out holes for the pegs, 5 mm diameter (a bench/pillar dill ensures the holes are aligned)
3. Cut the top view out
4. Chisel out the peg box
5. Using cabinet rasp begin to round the underside of the neck.
6. Using gouges and a rounded file begin to curve the underside of the head (image 2)
It is best to leave it fairly rough as there will be a fair amount of fiddling around getting the set-up right before actually attaching the neck. It just means you're less likely to mess up your nice smooth finish!
