Clock works great! I had to reprint gear 4b as one gear tooth was flawed causing it to stop. Using ender-6 with pla+. 8 day clock. Instructions are excellent.
The three weight shell bearings are fine with the factory grease since the speeds are low so frictional loss is minimal. The two pendulum support bearings are marginal with the factory grease, although I have never actually built a clock that way. Initial friction seems low, but it likely gets worse over time. The clock might work for a few months before the grease starts to get stiff and the pendulum amplitude reduces. My oldest clock with cleaned bearings has been running continuously for about four years. If you can't clean them because of metal seals, then your clock has the best chance of operating if you select the two with the lowest friction for the pendulum.

It should be OK for most gears. There is quite a bit of tolerance built into the design. It would be easy to test by placing a pair of gears in the frame and see if they spin freely or if they bind up. I would clean up any elephant's foot on the escapement, pallet, and the gear driving the escapement. Those are the most critical gears in the clock. Uneven elephant's foot on the escapement might prevent the clock from running. Minor elephant's foot on any other gears will probably wear off on its own within a short while.
It should be listed in the assembly guide. Each clock can have slightly different friction so some experimentation might be needed. 2 to 3kg seems like a good starting point in 4 day mode. Some clocks might need another 1 to 2 kg to run reliably.
Do you see any issues with using 1.4mm arbors instead of 1.5 or 1/6"? I have some of these already at the right length. I have the clock running with them on an initial test.
@@stevesclocks Thank you! I am currently running with water bottles for the weight while I wait for the BBs to arrive and the weight shells to finish printing. I'll post some pictures when it's done.
Great design, work great , thank you Steve.

Can you confirm if all the ball bearings have to be de-sealead and cleaned for this assembly?

Is there a place I can post pics of my clock build?

Would it be a problem if some of the gears printed out with a bit of elephant footing?

Hi.I made 4 day clock. How much weight don ı need

1.4mm should be OK. The gears may be a bit loose, but there should be enough tolerance for it to work.
