escap(ement)ism

[gfish]

Today was the Computer Science Graduate Student Association Annual General Meeting.

It got kind of boring after awhile.

So I made a Graham (aka deadbeat) escapement out of cardboard using my Leatherman.



It actually kind of worked, for the parts of the arc I didn't smoosh the teeth in too close together. With proper tools (compass, straightedge, protractor and xacto blade) I think I could actually get one working.

Need video! That's excellent.

I've tried similar things with Lego, though the gears' teeth are not the optimal shape. But they are selling a saw-like thing in their Indiana Jones series that might work better.

OK, I found a likely-looking gear in this set at Meijer last night, which is a whole lot cheaper:



and in case Lego doesn't allow hot links:

Maybe that can be the heart of a nice Lego pendulum clock.

Oooh, that looks pretty promising.

That looks suspiciously like something neuro42 and I made in high school, though that one was made out of plastic. Later I think we cut a rather vicious looking gear out of aluminum instead, but when the escapement became disengaged and the weight fell... Yeah, it was kinda scary...
