So I've been rebuilding an old guitar and I'm close to the point of assembling the beast back together.

Now....I filled in the existing screw holes with toothpicks as I figured it was a good idea so parts have a more secure fit. As its only soft toothpick wood, is it safe to screw the parts in by hand with a screwdriver? I don't have access to a drill press and don't really trust myself with a drill either lol.

Should I do this before applying the lacquer coat, then cover up the holes with blu-tac or something until the lacquer has dried?

if there is still a decent hole, I'd just screw them in. If you completely filled the holes I'd use a small bit to make a pilot hole
