SP14 Moon Phase Clock Trouble
Having a problem keeping the clock running. I have taken it apart twice and all appears to be well. It will run with an even tick from just a few minutes up to 2 hours or so. Appears to run well and all gears turn as expected without the escapement as the weight slowly drops. The clock doesn't stop abruptly, but gradually loses amplitude and slowly stops.
Currently I have 8.75 lb of BBs in the weight shell. I'm not sure what else to try. I've looked at and tried the debug hints, but nothing seems to help. When the clock does run, it seems to run well. My only thought at this time is to add an extension on the shell and add more weight, say maybe 10 lb?
I'd appreciate any thoughts and help. Thanks!

I had a similar situation with a clock I made. In the end I fixed it by polishing the ends of the piano wire shafts, reaming the plastic housings a few .001 over the true diameter and applying light machine oil to each spot in the frame where the shafts turn.
Also make sure you have clearance end to end. Should be about 1/8” of space. The plastic gears aren’t metal and aren’t perfectly round and aligned. There needs to be clearance all around to account for movement.
Finally, just let it run a while and I bet it sorts itself out. After making those changes of course.
