I found a gas can on the curb side 2 months ago and took it home for this purpose. It will be a 4 string 25" scale CBG with 22 frets. The filler/pour spout will be my soundhole. It will need a arch body type bridge. I have humbucker that I could put in it, but I keep thinking about a P90. Got the through piece cut and decided that it needed something to keep it from flexing. Can't install braces inside a can, so I dug out a channel along the through piece the length of the can and put a 1/8" x 1/2" piece of steel flat bar in it. That should keep it from flexing. Made a scarf joint for the neck and headstock. Need to cut a channel for the non-adjust trussrod(3/8ths inch steel rod). Then I can shape the headstock and back of the neck.
