[sdiy] Reproductions of Vintage Synth Parts (how are they made?)

[Adam Schabtach]

Let us know how it turns out, Bob. I was just thinking that the hard part of
the DIY molding approach might be making the shaft hole. I suppose it might
be possible to tap a hole for a set screw, but the threads might be pretty
fragile. Doing a hole for a D shaft seems quite dicey.
