Fixed Flying Tourbillon Model Mark 2

Update 11/19/19

I added 2 alternate pieces for the main spring assembly. The Main Spring Lug 2 Bolt Hole v2 and New Frame B Bolt Hole v5. Like the name implies, there is a hole in the Frame B shaft sized to be able to tap a 8-32 thread and an angled recess in the Main Spring Lug for a flat head 8-32 bolt 1/2" long. This keeps the spring in place so it doesn't fall out when handling. Just be sure not to overtighten and pull the shaft apart on the Frame B piece.

Timed at 21min and 30 seconds maxing out the spring. That was with the .006 shim stock around 12' long.

Update 11/16/19

Success! For shim stock, go with .006 thick 1/2" wide. The brand I purchase was from Precisionbrand.com . It comes in a 25' roll. I used almost 12'. I did a test run and it ran for 10 minutes! This was not maxing out the spring so it will run longer. 80 clicks of the spring yielded a 10min 21sec run time.

Also, the new winder tool is up to the task. I use .125 diameter by 1/2" l
