SB13 hands not moving
SP13 clock, the gears are all running well - been ticking away for 4 days now.
The problem is that the hands aren't moving - and I believe that gear 4a is not driving gear 4b through the friction spring.
I have checked 4b is locked properly to the arbour with the M3 screw, so it seems it is 4a freely rotating and not driving the arbour (and 4b) through the spring.
Any tips for debugging this specific issue? Thanks!

Quick question for the group - my clock is running perfectly on 2.7kg (~6lbs) main weight, but I am sure it will run on a lot less. Is there an advantage one way or the other to using more or less weight? Pendulum is currently plus/minus 14 degrees of arc.
I designed my own weight shell to suit a large lead ingot I had in, so it's a bit of a mission to cut sections off the ingot to try it (would be easier with lead shot obviously).
