Assembling and Adjusting a Count Wheel Based Hubert Herr Cuckoo Clock

Now that I've disassembled and cleaned this old Hubert Herr cuckoo clock movement, in this video I assemble the movement, and adjust the warning wheel position and the strike train great wheel position.

I adjust the warning wheel position so that the movement stops striking. A poorly-adjusted warning wheel will allow the clock to strike more hours than the current time, or to never stop striking.

I adjust the strike train great wheel position - which on newer cuckoo clocks would be the star wheel position - so that the clock stops striking at the end of a gong-coo-coo sequence. A poorly-adjusted wheel will either play the wrong sequence (for example, "coo-gong-coo") or will stop striking entirely.

It's a long video because you see me assemble and adjust this clock movement in real time. Most clock repair videos don't show this assembly or these adjustments, because those steps can involve tedious trial and error (as you will see!)

The clock movement is stamped "21", "Hubert Herr", "Triberg", and "Germany".  I found a description of a similar movement to this one, including a catalog picture, at: https://mb.nawcc.org/threads/cuckoo-clock-movement-id.78985/#post-595071. That catalog listing is from 1957.
