there are various folks making different parts are we just making these molds and everything based off of old parts? just a thought but what about creating a solid model that is perfect and then having the parts made? i do this all day with urathne/silcone and bunch of other stuff. if people have good examples i can produce SLA master peices that molds could be made from... this would elminate poor surface finishes in gaskets and poor joints in weaterstripping... let me know if any one wants to help out with this effort.
