How to design a 3D printed Graham escapement with FreeCAD 0.19

[@propsman7595]

Hello, I'm watching your video. i have a question Should the size of the first circle always be 160mm? Or is it okay to just draw the angle regardless of the size? I'm Korean, so I'm not good at English. I'm sorry for that.

One thing I am still struggling to grasp, is how to determine the needed radius for an escape wheel. I have planned out the sizes of my 2nd-4th wheels and my pinions, but so far I can't figure out what radius escape wheel I will need to work well with them. If you have any insights, or resource recommendations it would be much appreciated! Thanks for the wonderfully informative content!

smaller is less friction, but smaller need more prescision in my roskopf watch I was able to go as small as 40 mm for the escape wheel , printed on a Ender 3 and I use module 1,2

Thanks for posting these quick CAD tutorials for designing clocks. You make it look so easy.

You are welcome I suppose a life long experience of building, fixing and tuning mechanical devices does help. It is my pleasure to be able to share this knowledge with others

Wow! you taught me something new again! I had no idea you could switch between construction and final in the sketcher to keep all those references there without having them show in the final piece! thank you so much!

Great! thanks for the feedback. FreeCAD is full of treasures, totally worth spending time learning

thank you mr Jacques! of course this was REALLY helpful! you see, I want to give a try on designing an printing a clock myself :) dind´t know where to start and came across your channel! thanks! greetings from Guatemala :)

Merci beaucoup de publier ces vidéos. Je voudrais vous demander si vous connaissez une façon de dessiner un dent d'engrenage et le repliquer afin de pouvoir y appliquer les calculs faits par la calculatrice de Csparks? Merci bcp.

[@jacquesfavre999]

Je ne sais pas le faire mais tout les calculs sont ici: www.sdp-si.com/resources/elements-of-metric-gear-technology/page4.php c'est aussi ce que le "Gear Workbench " dans FreeCAD utilise tout le code Python utilise pour générer les engrenages est accessible
