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

[Bob Weigel]

Like I say on this particular case, we're dealing with a flat metal 
shaft thing.  So if I drill a 5/32" hole I believe it is...in the center 
of the knob, then the shaft will fit tightly.  I'll have to allign it on 
axis of course :-).  But then you just put goop automotive adhesive or 
E6000 in it and stick it on there and let it dry and voila.  Works just 
like the stock one and never will fall off unless you want it off. -Bob
