I am about to drill control cavity holes in my carved-top bass body. I've always drilled from the inside of the cavity out to the front of the bass before and that has worked fine. The problem in this instance is that, because it is a carved top, it will not lie flat on a backing board and I'm affraid that when I drill, there will be a great deal of chipping of my AAA Flame Maple top. Can anyone offer advice on how to properly drill in this situation? Thanks in advance for your help.
