Скачать или смотреть Brian May Stratocaster Conversion - Thermosetting Brass Threaded Inserts into Perspex Sheet

This short video clip illustrates the stages involved with thermosetting M3 brass threaded inserts into the perspex plastic. The initial holes were drilled to 1/8" (3.2 mm) diameter. After holding the carrier plate down on my drill press bed with double sided adhesive tape, I first locate the hole using the 1/8" drill bit, then I swap to a 3.5 mm drill bit and open out the hole. Then I insert a length of M3 stainless steel machine screw with the brass threaded insert on the end. I heat this using an electric heat gun and slowly press it into the 3.5 mm hole.

Once all three inserts have been thermoset into the plastic, I file off the excess with a diamond file and dress the plastic surfaces with 320 grit abrasive paper prior to gluing onto the underside of the pickguard.
