Can Opener Re-Gearing

Six years on, I just deployed the last of the aluminum spares from the original CNC project:

I swear the cutter gear on the left does not show that rust in person!

This can opener has a slightly larger bolt than the previous ones, so I embiggened the hole with a step drill:

Having run out of aluminum gears, I’ll be forced to make a hob to make a steel gear. Drat!
