Checking the length of the mainspring in a skeleton clock

I will show how to safely remove a mainspring and the formulas used to calculate the proper length of a spring to fit in a barrel. This is part of the series of videos documenting my build of a perpetual calendar skeleton clock by L.G. Brown.

Really interesting.
Also nice music från Wintergatan with perfect volume. A lot of videos out there have way to loud music.
