Planetary Clock

grabcad

A wooden clock with a planetary mechanism between minute and hour hand.I usualy tend to build all of my designs, but this one will probably stay as a model. Why? It's huge as a tower clock...I dimensioned the gear modulus to be cut by D3 endmill out of plywood, but the result is too big to be acceptable as a dust collector. You can scale it down, yes, but please keep the pendulum lenght ~1m for 2s period, otherwise you may end up with Alien clock;-). Therefore some final details are missing, like backlash gap in the gears or axial fixations. The clock should be working fine though , at least F360 kinematics simulations shows it should.
