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

[flightofharmony]

Because they have to pay someone hourly to do it. And if they're union,
"that's not in my job description".
The drawbacks of big shops. :)

-> I'll bet that would take them all over  5 minutes to make the mold, 5

-> I'm asking! :-)  Why don't they want to make 400 dollars per hour when

-> hehe.  I guess I'm more accomidating in my business.  And if I did that
-> kind of business I would actually probably do a run like that for 34

-> person whose lost all their slider caps like one I have here right now
-> could go in and get them at ar reasonable price.  Bore them and paint
-> them in another hour and have 80 bucks into a set of knobs you can't
-> get...but which would look identical to stock pretty much and would
-> increase the value of the instrument 140 dollars.    There are just tons
-> of things like that an innovative person could do if they had a facility
-> already set up to do bigger tasks.  Why not when it takes less time to
-> do it than to talk to someone about not doing it? :-) -Bob
