Greetings
Thanks for having me. I make clocks, incense burners, lamps, and whatever else comes to mind. I enjoy fixing broke stuff, and don't mind lending a hand to those in need. I look forward to discussions and learning genuinely useful things.

Welcome, Daniel. It's very nice to meet you!
A clockmaker! One of my favorite topics. I've studied and even attempted gear hobbing, and even clockmaking. I just love clockwork mechanisms, but I always fail when making the escapement. It seems to require more precision than I can muster.
Any hints for someone who has yet to bring one to life?

Angle and spacing on escapement teeth is critical. if they are off it will run away or not move. Which do they usually do?

It never moves. I know this can be an issue of depth, or or angle, or of friction as well.
Say, you don't have a drawing for a grasshopper, do you? I have the design PDF, but without a practical model it's all theory.

grasshopper is pretty complex. I have messed with deadbeat escapements. the teeth on the escapement are cut at two different angles, the deeper ones to hold the gear and the outer one is cut for " impulse" to keep the pendulum going.

I've tried basic deadbeat, and even recoil escapements. Graham is a "simple" one. But I never seem to end up with a successful escapement.
The grasshopper is of particular interest to me, because my interest lies in woodworks. Very beautiful, but very high friction, which is not a weakness of the grasshopper. Harrison was a genius.
Wouldn't mind a Grimthorpe gravity escapement, either...or a MacDowall single pin, but talk about something that's *deceptively* simple looking. Wow,

I dont think the actual design is the problem, build one and adjust the tooth angle a tiny tiny bit at a time.
If it has a pendulum make sure it is heavy enough.
