Wonderful upgrade Art.

Just a small request:

The teeth on the escapement gear are very thin which works well for brass gears but not so well for wooden ones.
There is a lot of clearance ahead of the leading edge of each escapement tooth; is it possible to fill this in with extra tooth thickness?
This would make for a much stronger wooden tooth.

best regards, Gary

Gary, my hat is off to you.  I only downloaded the latest GM version yesterday and spent about ? hour fiddling (of course without reviewing the tutorials   :)) and was happy to just get something that would actually go tic-tock!
I have a question; in your project does the animation move the minute and hour hands properly? Or another way to pose the question, can gears, i.e., the hour wheel, be placed on a co-axial but independent axis?

Hi Al,
The hour wheel IS placed on a co-axial and independent axis. Physically you would use one shaft inside a hollow shaft.
i.e. the minute hand would be mounted on the hollow (tube) shaft that carries the minute gear and pinion, and the hour gear and hand would be mounted on a shaft running inside the tube (which acts as a bushing).

Clear as mud?

regards, Gary

edit:
I've attached a small video of the clock running after fiddling around trying to make it under the 4000K limit. But now I notice it won't play with Windoze Media player directly but does work if downloaded to my desktop before playing  ??? ::)

Great!  Thanks!

I don't have a way to test them, but the pawl cut fine and looks good, both in luaun and OB.  Omega-Bond will machine fine with the same feed and doc as cheap plywood, and the result looks like it should be good for gears and clock parts - the aluminum cladding really stiffens the poly core.  I think I owe the sign shop my (optimistically speaking) first Omega-Bond clock for giving me a stack of it.

Here's a couple pictures.
