Following NIHS - Refactoring
Just spent some time nerding out on mainspring dimensions and barrel fits with the help of chatgpt and Alex from watchrepairtutorials.com. The technical details are stacking up, and I'm inching closer to a killer prototype. Sneak peek: going for 28,800 vph with some precise wheel train magic. Check out the sketches and let me know what you think! 🛠️⌚️ #WatchmakingJourney https://thebitcoinwatchmaker.com/post/view/following-nihs-refactoring/
Following NIHS - Refactoring.
Been closely following NIHS standards, with the help of chatgpt, and Alex from watchrepairtutorials.com calculated precise mainspring dimensions:
- Thickness: 0.13 mm
- Length: 551 mm
- Width: 1.33 mm
Additionally, I ensured the correct fit of the barrel arbor, with a total height of 1.58 mm to fit smoothly inside the barrel, maintaining a clearance of 0.1 mm on both the top and bottom to prevent friction. I've also decided on the use of a bride rapportée (inserted bridle) for its superior control in automatic winding. The technical details I've explored, including the use of Nivaflex mainsprings and calculations based on NIHS 11-02 standards, bring us closer to a well-engineered movement.
Stay tuned for more updates as I push forward with the prototype phase!
Barrel arbor, Mainspring barrel
Escapement (yep missing the safety pin) -- target: 28800 vph
Im thinking of going with KIF, but need to explore more
Train of wheels -- with proper reduction for the fourth wheel and minute wheel
