Very nice Steve.  :thumbup:

The grasshopper is nice to watch.

Did you use CNC for any parts (e.g. Dial)?

After a bit of a problem with the spring barrel being too tight it's now starting to keep good time.

The dial, controllers and some of the wheel crossing was done on the CNC mill

I plan to get a glass dome when I see one the right size and price.
Would be nice to see a photo of your clock

I made this as a test and learning piece, when I first converted my mill to PC control, I ended up making three I gave two away to mates....... :ddb:
