It's a pretty simple setup for the most part.The springs and such are hidden due to the folded design of the houseing.That's why I think a clear plastic jig would help alot of people in the future.At lest enuff to show placement of parts and what areas may need attention for polishing?
I love these tutorials! They show just what a man can do when presented a issue and his means to solve the problem! Keep us informed.
