8 Day Clock

I have been working on a clock that could run for 8 days
I designed an efficient escapement with 1 mm steel pinson the anchor and 3 D printed escape wheel
The gear ratio is 1/8 x 1/5 x 1/5 x 1/5 = 1/875
With a 50 mm drum and a pulley I get an 8 day power reserve with a little over 1 meter of drop of a 3.5 kg weight

absolutely amazing! 👏

Look forward to your plans when ready as I have built all of your other clock, A nice new winter project

Excellent work, Jacques!

[@supremeinnovationsllc]

Looking really good.

[@julias-shed]

That is really impressive well done 😀

[@JulianMakes]

Good progress!

[@jacquesfavre999]

Yes, thanks

Encore un superbe travail J'utilise beaucoup le PETG pour les pièces de mes maquette bateaux, il moins sensible à l'humidité et plus résistant que le PLA

[@jacquesfavre999]

Merci Quels sont vos réglages? et sur quels surface? Oil j'ai lus que le PETG est plus resistant dans le temps mais doit être bien sec a l'impression, le sécher vous?

[@salertimpression3d740]

@@jacquesfavre999 Je règle comme vous buse 240 plateau 70, il faut faire attention à la température du local et des courants d'air, pour éviter le warping, j'ai en préparation un caisson pour les deux imprimantes Ender 3 et CR6CS, Qui sont toutes les deux en panne, CR6SE carte maire grillée (en branchant le cordon USB) et Ender 3 pas de vis support buse hs, il peut aussi y avoir des problème des cheveux d'anges, voir la vitesse et rétractation. Pour le PETG, je ne le sèche pas, mais le PLA je le tiens bien au sec !! pour l'adhérence sur le plateau, j'utilise de la laque forte pour les cheveux.

I want DXF for laser cut.

Hello Jacque - do you have the plans for the 8 day clock as the myminifactory link doesn't work. I am happy to pay for the plans. All the best John

[@stevesclocks]

Awesome job. The best I have been able to reliably achieve is about 1 pound (0.45kg) drive weight per day of runtime. Adding more weight gives a larger pendulum amplitude and the clock becomes more stable. Winding once per week makes the clock really easy to keep running. I am curious about the PLA vs PETG comparison.

[@jacquesfavre999]

Thanks This clock too is in the same range: cults3d.com/fr/modèle-3d/maison/8-day-mechanical-clock-for-20x20-bed also 3.5 to 4 kg for 8 days, same as a traditionally made clock according to the author Eventually I will have to compare gears in PETG versus PLA Also want to try ABS or ASA, it should be possible to print gear in open printer with a good bed temp The reason I went for PETG is that it is what Prusa uses for their printer parts They certainly have some experience about printing in PETG and how it last in time I happen to have got a Prusa Mini Clone by Fystec, and just by printing the parts, learning a lot about 3D printing design and some magistral failure Time will tell

Good day, sir. I want to start studying horology and clockworks, which book or documentation would you recommend for a starter?

[@delllaptop9095]

Just post the installation tutorial for putting this part together

[@RalphKoettlitz]

ABS may be a better material. But ABS needs a printer like a Voron in an enclosure.

[@twinturbostang]

What is the purpose of the pulley? Sorry, I'm new to pendulum clocks. It looks like it might give you twice the run time. But that also means you get half the force on the escapement wheel. Is that enough? Or do you need to double the weight?

[@jacquesfavre999]

yes the pulley allows to double the run time, with twice the weight

[@chrisdepalma6844]

I assume basement. High humidity on filament?

[@jacquesfavre999]

actually a shed in Florida, no shortage of humidity. I have started to use a drier, it does make a difference for printing There issue here is with a finished part that degrade over time

Can I contact you to purchase your designs? im feom vietnames
