| Reproducing plastic parts is common to hobbies other than automobiles, so 
there should be a body of knowledge for it.  I recall reading somewhere that 
RTV 
molds and casting in polyurethane gave good results for reproducing antique 
radio knobs.  (It was here: http://www.stanwatkins.com/hals38.htm)
Many years ago I successfully made some small (non-Bricklin) parts with 
liquid latex, plaster molds, and casting resin or Liquid Steel, but was 
completely 
"winging it."
Are you planning to make any Bricklin parts and if so, what?  If I can't 
locate any Bricklin radio knobs, those might be a candidate.
