Hi, i just made a neck with the tilt-back design and was using 3/4" wood for the neck. Now i have a 3/4" neck and a 3/4" headstock thickness, how do i thin it down? a router? Thanks for any info, i cut my 11 degree angle and flipped the peice over like I was supposed too. I don't know whether to trim the top of the headstock or the bottom to get right thickness.
