This is fun. Good work. Looks like another thing to put on my “To Do” list.

hi that looks like a fun project great construction how long did it take you to complete it
i really really like it branch

branch: For once I DID keep a note of hours spent – albeit not TOO accurately!

I estimate about 80 hours actually in the workshop, but quite a bit of that time would have been saved if I had the correct thickness plywood for the big gears – mine was about 1.5 mm undersize which meant that the marbles were very close to the surface. Also, a decent Forstner bit to cut the holes would have given cleaner recesses. I used one from a cheap set which has cutters that appear to be made out of cheese!

Gnagen: I added a note to the main text about the need for a lathe

Nice job… How long did it take you? I’m thinking about making this someday. I will for sure purchase the plans.
