Submariner case technical drawings/specifications

[jmb]

Does anybody have a drawing or sketch with the "important" dimensions, etc., of a gen (or gen copy) Submariner case? I have some 303 stainless laying around and when my rotary table gets here I think I'm going to attempt to mill out a case. I have dies for threading a crown tube and I think all of the tooling I need to mill out the case. The only part that might be problematic is the case back as I don't think my lathe can cut threads that fine but I'll cross that bridge when I get there...
