Hi there. I make little changes to the large pendulum clock and now is working with the auto winding. I travel a lot so I prefer my clock keep working when I'm not at home. The clock has been running for 45 days without stopping. Just a little slow, like 5 to 6 minutes a week. I have to adjust the pendulum to try to fix it. This is the link to my clock. https://youtu.be/3uTMAPNFbJY

@Steve You right Steve. The clock is running with less than 2 pounds (30 ounces) of bbs. And still have 3.5 degrees in the pendulum.

@Steve https://youtube.com/shorts/v6uCPtyWboc?feature=share I finished the clock using the igus i150 filament. All gears except the pallet are igus i150 filament. Tha others parts are PLA. The clock start running since beginning without issues. Is running for about 48 hours now and I noticed that is slow 1 or 2 minutes each hour. I will adjust the pendulum to improve the time. I'm not sure if printing the clock using igus filament worth the effort. It is pretty difficult to print. You have to use some glue to keep it in place and even if you manage to keep it on the bed it can separate from the middle of layers. After a lot of changes I finally made raising the temperature to 250 and the bed to 65 and using a glue called bed well from layerneer. I try printing on my two printers (prusa MK3S+ and Anycubic I3 Mega X) but only works in the mega. The other thing is that filament have only 2 maybe 3 colors (black, white and something bone like color) Only the time will tell us if worth the effort because the filament is much more resistant and can be used outdoor. I let you know any changes. David.
