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

[Bob Weigel]

Thanks Ken,

Yeah I had some joysticks for Korg and the like made via computer aided 
machining.  Nice job on the plastic helmets!  That reminds me I have a 
relic setting here I'd love to get into a museum somewhere.  I found 
this...really bizarre thing in California ..LA area somewhere on a 
hill...can't even recall where I was.  But it's a gas jet with a 
swastica on both the handle and the body. 

Anyway I think I'll go with just a clay for this one since it's 
basically mailbox shaped (like a ya know..large street mailbox for 
dumping mail into). If I have success I'll report on how it goes. -Bob
