What is the difference in European and US glazing U-Values, what assumptions do they rely on and how to convert them?

Great question, although the title could use some focus. In an actual question, "what's the difference" and "what assumptions" could be moved to the body of the question. – Air Jul 18 '14 at 15:38

Questioner would provide some design details and constraints in the question. – NauticalMile Oct 15 '13 at 20:15
[part source] might be lathe, mill, CNC machine, casting, etc... – NauticalMile Oct 15 '13 at 20:29
I think right now the question is a little unclear. Maybe "What's the simplest mechanical device/mechanism to do [X]?" and "How do I adapt mechanical device/mechanism [X] to [specific application]?" would be better questions? – andy mcevoy Oct 16 '13 at 14:01
I agree, it was a little unclear. Thanks for the suggestions. – NauticalMile Oct 16 '13 at 16:04
