So I'm no tech or luthier (correct my spelling if incorrect) but I'm and very interested in building some guitars... i think i have the common sense enough to learn the trade fairly well. one question. so in the cavities for the pickups there is usually a drill hole (in solid body guitars) for wires to run from pickups to pot cavity. how do you drill that out considering how deep the cavity is not? any help would be appreciated.
