Hello, I suposse you know to make the gears in plywood before. The question is compare wood gears in front of printed gears, are you more happy with this new way. Thank you in advance.
Hello, I love your videos and descriptions of mechanical clock mechanisms and was wondering if you could do a video on the Arnfield escapement in Fusion360?
Very interesting results. My experiments showed minimal difference between various tooth profiles. Steel pins rubbing against PLA will be much lower at the cost of a lot of extra effort creating the pins. My suspicion is that any reasonable gear tooth profile will perform good enough for an 8 day clock. The dominant factors affecting runtime are escapement efficiency and pendulum support friction. The detent escapement looks really cool. Did you have the microphone right on top of it? Both escapements seemed really loud. :)
Yes the micro is on top of caméscope, so just a few inches from escapement Lots of noise is also a sign that the escapement is not very efficient yet The detent escapement is one I wanted to do for a long time, looks so simple and yet can be tricky to get right It works well with the cylindrical spiral spring For the pins Amazon has them by the hundredth for 8 bucks Not worth making them myself I think cycloid is still a good option with small pinion, below 12 Watches still often have 6 at escape wheel
For the carbon spring: Instead of using a mould, it might be possible to use carbon fabric (or a roving), and some spacing material like a polyethylene band. Put the impregnated carbon fiber onto the plastic, and wind it around a core and let it cure. Afterwards you may cut it into slices on a lathe or even just with a saw. Remove the plastic, and the spring is ready. You may be able to get thinner and softer springs compared with moulded ones.
Yeah, thinking of a silicon mold that I can un roll to place the fiber, then roll to get the final shape Ideally it would be best to have a constant stream of fibers all around the section of the spring should be between 0.1 to 0.4 mm in thickness and 0.5 to 1mm wide fun stuff
what you see around 0:30 is after a month of running, pins are shinny, no dust, I do not see any wear on the anchor There is only about 2 grams of pressure pins to anchor I am quite certain the clock will run a couple years... time will tell
Thanks for sharing

can you experiment and see the efficiency of the lantern pinion? because some watches mount it
Yes coming soon
Quite curious how it is going to go

Bonjour Jacques
Encore un très gros travail et une très belle réalisation.
A bientôt pour l'impression, quel filament avez-vous utilisé, PLA ou PETG.
Is there any pdf file to teach how to install the clock parts
Sorry not yet, life got busy with other things, hopefully cab get back to it sometime soon
Superb!
Do you notice some wear and tear at the escapement over some weeks of use?
what you see around 0:30 is after a month of running, pins are shinny, no dust, I do not see any wear on the anchor
