TLDREnergy transfer in a watch involves the balance wheel nudging the pallet fork to release the escapement wheel, which then slides energy from the mainspring to keep the balance wheel oscillating. The key is optimizing the angles and contact points for efficient energy transfer, so the watch ticks smoothly. 🎥 Check out the animation for a visual breakdown!

Transfer of energy
This took me longer than expected to understand. Turns out:
The balance wheel gives a small push to the pallet fork, allowing it to release the escapement wheel.
The escapement wheel, powered by the mainspring, transfers energy to the pallet fork by sliding along the impulse faces of the pallet jewels.
This energy is delivered to the balance wheel, providing the necessary impulse to keep it oscillating, which is why optimizing the impulse angle is important for efficiency.
Notes:
There are indeed two forces: one from the balance wheel, and one from the escapement wheel.
The pallet fork angle is crucial to allow the roller jewel to enter, be caught by the fork, receive the impulse, and exit smoothly.
The roller jewel must make contact with both sides of the pallet fork to transfer energy efficiently.
The shape and strength of the roller jewel are important to handle impacts on both
At least this is how I think it is, cant make any guarantees yet hehe
TLDRJust updated the fork design with precise rotation, setting a 10° side-to-side bounce angle for better performance. Check out the video for a visual on how it all works. Perfect for those interested in the mechanics behind the build! 🛠️

Top part of fork
Added the proper rotation to the construction, so the shaft will bounce at the proper angle with a defined width.
It will have 10° from side to side
TLDRYou're exploring different options for your watch's escapement, specifically looking at a 21600 vibrations per hour (vph) setup after finding 28800 vph may be too much. You've got setups ready for various tooth escapements and are fine-tuning the design, adding more parameters for customization. The takeaway? You're diving deep into the mechanics to optimize performance and design. 🕰️

21600 vph
After continuing studying NIHS standards, I noticed a vph I was not familiar with... 21600vph
Is it good? I dont know, but since the 24 wheel is what I need for the 28800 vph, and according to chatgtp it might be a lot, Im trying other options
The good thing is that I have setups now for 15-18-20-24 teeth escapements.
TLDRTinkering with George Daniels's escapement design, I had to modify the angles and symmetry to get it working with more than 15 teeth. Still fine-tuning those angles, but I've put together a quick animation to show the progress. Watch the video to see the mechanics in action! ⚙️

Escapement Wheel Continuing
Ok I could only take George Daniels's escapement so far with the 15+ teeth.
Had to start modifying it, angles, symetry and more, to make a working escapement.
I think I still need to improve some angles, heres a very quick animation
TLDRYou're diving into George Daniels' watchmaking with a focus on the "Semi Equidistant Club-Toothed escapement," nailing it with 15 teeth but hitting a snag with 24 teeth, especially with the locking face angle and left jewel placement. If precision watchmaking and problem-solving with escapements is your jam, you'll find this journey relatable. Check out the sketches for a closer look at the challenges you're tackling. 🕰️

Escapement Wheel
been making a script that follows George Daniel's Watchmaking,
particularly the "Semi Equidistant Club-Toothed escapement"
(which I think is a good option?), and it works great for 15 teeth escapements,
but, for a movement Im working on, I need 24 teeth,
Im mostly having trouble calculating the Locking face angle and the position of the left jewel.
TLDRGot a fascination for gears? This blog post dives into mastering the Joint function in Fusion 360 to precisely position a "train of wheels," ensuring each gear fits perfectly. If you're into watchmaking or intricate machinery, it's a handy guide with gear specs and a video for practical insight. 🤓

Wow fusion is quite powerful,
Here Im learning the Joint function,
This will allow me to position the train of wheels exactly as I will like it, keeping the circle dedendum of each gear in place for the gears
TLDRGot some new gears for the watch movement, but had a hiccup with the fourth wheel since the escapement didn't fit—had to swap it out. The post dives into gear ratios and specifics if you're into the mechanics. Check out the video to see the gears in action—it’s pretty satisfying! 🕰️

New gears in the movement! woho!
I had to change the fourth wheel though, as the escapment didnt fit... oops
Main Barrel m=0.1298 z2=112 z1=16 ratio: 7:1 a=8.3072
Center Wheel m=0.104 z2=80 z1=8 ratio: 10:1 a=4.576
Third Wheel m=0.104 z2=60 z1=8 ratio: 7.5:1 a=3.536
TLDRCreated a script to design a wheel and pinion using the NIHS 20-30 standards, and there's a video demo to check out. This is niche stuff for watchmaking enthusiasts or anyone into precision engineering. The real takeaway? It's a practical tool for those in the field, blending tech with tradition. 🕰️

NIHS-2030: Wheel and Pinion
Made this script, that creates a wheel and pinion using NIHS 20-30 standards
TLDRIf you're into gear-making, the NIHS standards like 20-01, 20-02, and 20-10 are your go-tos, but the new NIHS 20-30 is the latest hotness. It's not available open-source, but the author plans to upgrade their project to this new standard. Check out their work on GitHub for some cool insights into cycloidal gears. ⚙️

NIHS 20-01 NIHS 20-02 NIHS 20-10

This look amazing, but apparently there's NIHS 20-30 now, which is the latest, just purchased it, but I dont think I can open source that one
As is, it works and follows the rules, but will move to 20-30 and make it awesome.
TLDRIf you're into watchmaking, check out the British Standard 978 part 2 for cycloidal gears, as recommended by George Daniels. It's a solid guide, but the NIHS standard might be worth exploring, too. For more hands-on details, the GitHub project linked in the post offers practical insights. ⌚

These are a nice set, but it seems NIHS is also an option, will explore
