I was super hyped, becuase i really like mechanisms as a whole. Came out pretty good. When i first built the tourbillon i was sceptical, because when using to little force on the runner wheel it would'nt run at all and when using to much force the impulse pin jumped out of the fork and the mechanism was blocked. The difference between not working and getting stuck was very little, so i ended up modifying the fork and made the prongs longer. Now it doesn't block itself anymore.
The only thing i have to figure out now is the timing of the assembly. Right now its runs way too fast. Also the speed depends on how much i wind up the main spring, which sucks.
Since i dont want to add weight to the balance wheel, im tuning it trying different stiffnesses for the main spring.
