My apologies for the fireworks bangs, I didn’t want to wait for a quiet period to reshoot that footage. I don't think it’s so bad that the footage is ruined.

You can find Fusion360 files for some of the gears shown, and the shaft drilling jig here:

I have made extensive use of these two references, which you can also consult if you don’t have the time to wait for my upcoming uploads:
