Printed Clocks

Hi Steve,

I have just finished building your rolling ball clock and am experiencing a issue with it which i hope you can point me in the right direction with.

1.free pendulum swing was just over 9 mins

2. all gears run freely on their arbours

3.the clock will run sometimes for 1.5 hours and run through ball drops no probem but then stops randomly?

4 one issue i can see is that pallet engagement is further in the tooth on the right side than the left with what ive learnt building your moonphase clock it needs to be level to make the engagement the same booth sides is this the case for this clock ? i have the pendulum arm set in the midway point at present

I would be very grateful for any advice you may have,i love this clock and just want it to run as my previous builds have
