Hello all! This is my first post in the Luthier's Corner. I'm new to the whole thing of building guitars, although maybe I should clarify that I don't actually build them but more accurately assemble them. I get most of my necks and bodies from Warmoth but as I come across something I like I'll use it. Anyway, I am doing a P-Bass project with a body I picked up somewhere in my travels with a Warmoth 21-fret neck. The Warmoth fingerboard overhangs the heel by approx. 3/8 to 5/8 of an inch. The truss rod adjustment is in the heel of the neck and I need to cut a trench in this body. The trench needs to be no less than 1/2 inch wide and (estimating) 3/4 inch long. My question: what is the easiest, safest way for a newbie like me to cut the trench without totally messing up the body? Is there a Dremel tool that will work or is this something left to a professional with a vertical mill or something? Thanks for your feedback!
