Ok, after a week upstate for work without a machine that runs OpenSCAD I'm back home and have a few hours for the clock project.

Have I missed anything and what is the timeline for the next few weeks? Are we doing another clockathon soon?

My immediate plan is spin off a four gear, larger diameter clock, and create a working single-layer ratchet design. What's everyone else doing?

I'm printing this now. Hopefully it will work and I can collect my lessons learned to share with the group. With the panelization there's ~21 separate pieces that need printed and put together for the case, and thats just the back. I'm still working on the front, so double that number in the end probably. (I'd bet the back could be re-panelized to fit on a Replicator in about 3-4 pieces). To get a sense of scale the case is roughly 360mm tall and about ~180mm wide. If everything goes well i may take a shot at a floor standing pedestal for it to sit on, but that's putting the cart before the horse. (Ignore the pulleys on the outside of the case, they were removed.)

Wow!

That's just gorgeous. How well does that escapement work so far?

Outside of the last video i'd sent, I don't really know as I haven't 
tested the latest incarnation.  What I did notice was that the printed 
objects round the corners of the pointy parts of the the palette faces 
and escapement wheel teeth because the very ends are too small to print 
with the 0.4mm nozzle i'm using. My latest test tries to compensate for 
that rounding to ensure that the teeth are engaged with the palette 
faces when they're supposed to.

Yeah, that's the biggest reason I switched to club toothed escapement wheels, but no reason a little tweaking can't get good results with pointy teeth, and it makes it easier to keep thirty teeth on that wheel!
