I am working on my first build, a jazz master body with all tele hardware. I ordered the body ruff finished and routed so a jack socket hole is already there. I have an electrosocket to install but am really hoping to flush mount it in the existing hole. Does anyone have any good ideas on how to go about flush mounting it? If I were drilling the hole in the first place it would be easy as I could drill the larger opening first then come back with a smaller bit to finish the hole, but now I have no center point. My current thought is to scribe around the jack socket with a sharp knife and carefully clean it out, but I am open to any ideas before starting on it.
