Wooden clock help
A joiner where i work is making a very expensive kids play house. It is very special and a work of art. On the tower he is putting a clock on it.
Instead of just a plain clock with fixed hands, i have been searching for something off the net whereby the hands can be gear driven but instead of a
battery powered mechanism it can be operated manually by a handle from inside the tower. It ideally would need to be made totally from timber. Does
anyone have a link to a design for such a mechanism?
Its a bit like a kids teaching clock but turn one handle and the hour / minute hands turn together in the correct ratio.

Just a random thought - if you DIY use timing belts (3:1 & 4:1) rather than gears - they're a bit more amateur assembly friendly.
Unless you want the gears to be visible as part of the design.
In that case is it possible to get them laser cut?

remember gears and fingers don't mix, so if you've got gears etc make sure they're shielded from kiddie fingers etc

The entire thing can be made from wood, if he's very good. Lignum Vitae, IIRC, is a self oiling wood used to make clocks. Might take a while
longer than he wants though. Also, not sure how damage proof it'd be.
