This ’54/’55 Silvertone 1377 had a broken pickguard that had been repaired by adding a piece of 1/8″ masonite. I have never worked with heat molding plastic so it gave me a chance to experiment with a new process. I found several online videos demonstrating suction molding using an oven to heat a sheet of plastic that is then quickly transferred to a mold. I figured for the small size that I required I could heat the sheet of plastic with a heat gun right on the mold using a shop vaccum for suction. It took a few tries but the result was quite good.
