so, this is a fairly well known trick but I haven't seen too many videos for it so thought I'd document my take. using a router and a fence to cut both pieces using the front and back sides of the bit simultaneously. I'm not comfy with a jointer and don't have one for that reason... if you are like me - this might be a solution for you. oh, and before you kick me out... this is for a 32" scale walnut p bass. my first scratch build. might be ready by next winter so... hehe.
