What resin should I use?
I have a 1958 Pfaff 332 sewing machine with a broken knob made of bakelite. Replacement knobs are not available. It occurred to me that it might be possible to cast a replacement with a different resin. I have no experience with casting and don't know what kind of resin would be best.. I saw the antique radio knob replacement ible, and liked the idea of using a flexible mold for detail.
This knob engages a major cam mechanism and should be fairly strong. The old knob 'handle' was broken off when I got the machine. The images of complete knobs are from the web. The complete knob is about 1 inch by two inches.
What product available in the USA do you recommend?
