This is another of Matthias Wandel’s super designs – but a bit more light-hearted than his joinery jigs, gear making programs, etc.

I made mine from plywood, pine and maple, with some oak of a suitable size for the bowl (which is the only part that requires the use of a lathe – gears are cut on a bandsaw).

I really enjoyed the build, and I have to say that Matthias’s plans, including still pictures, text, and videos with their clear and concise voice-overs, make construction very easy to follow. His Bigprint program also made creating exact life-size drawings of the components simplicity itself.

I used a coat of Danish Oil to finish.

There is a video of my version in operation at http://www.youtube.com/watch?v=oxTSrg44w5E but there are better versions on YouTube posted by Matt, including:

I think my grandchildren are gonna love this . . . . .

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.
