Hi Steve,
The local filament supplier has discounts on their filaments and have been toying with the idea of buying some wood filament and printing the deadbeat version of your coup perdu using this wood filament.
Have you had any experience in using wood filament and would the frictional forces be too high for this clock.
I presume that unlike PLA I would probably need to sand/polish the gear teeth??
Any thoughts???
Cheers

Real wood filament PLA has a rougher surface than standard PLA, but it should still work. There is a risk that friction will be higher. You can do a few things to minimize the risk.
Print the deadbeat version of the clock. It often runs without any extra weight, or just one pocket filled. You will be able to add extra weight if needed.
You may want to sand the pallet and escapement since those are the surfaces with the most sliding action. The gears should be fine.
Add some lithium grease to the pallet and escapement.
