Re: Tek Knob Project - scan and make

Not necessarily.  You can cast the knob twice, then slice the mold in two with a razor and combine the two good halves to form a complete mold.  I have not done this for knobs, but I have done it for plastic gears, and it works, assuming the knob is symmetrical.

The knobs are plastic primarily for cost of manufacture.

Has anyone explored using RTV silicone rubber to form a mold of an
knob, followed by using the mold to cast a replacement knob using
acrylic resin (or another compound)?
