Hi folks. I'm building my first CBG and so far so good. I do have one issue I haven't quite worked out yet. I'm going to install a piezo pup wired to a phone jack and my issue is this: how to firmly attach the jack to the box. The screw thread end of the jack isn't long enough to penetrate through the 3/16" thick wood for the mounting bolt to attach to. (The jack in question is the 1/4" panel mount jack from Radio Shack.) I was thinking of dremeling some of the wood away from the inside of the box but I think that would just weaken the mounting area. How do you guys do it?
