You are absolutely right. I wanted to touch on that but didn't want to get too wordy. Plus other land animals (like birds) have a different solutions for the toxic Ammonia problem.

This is one of those things that can get super complicated the further down you get into the minutia. OP's question was fairly simple so it's basically food+metabolism+liver=Nitrogen in urine.

In our bodies? No, it's not from the air, it comes from food you eat. Pure Nitrogen is too strongly bonded together to be useful in plants and animals. Microorganisms break down the N2 into nitrites and nitrates so that plants can use it, then animals eat the plants (or animals eat the animals that eat the plants.) Nitrogen compounds are also manufactured industrially for fertilizers.

See: The Nitrogen Cycle

Ultimately the main Nitrogen compound in your urine (urea) is produced in the liver from the breakdown of proteins in the blood. This would normally create ammonia (like what aquatic animals do) but Ammonia is a powerful oxydizer and highly toxic, so our livers bond two Ammonia molecules to a Carbon Monoxide molecule to make it safer for our urinary track.

The pin is pressed into the shaft. You should be able to knock it out from the other side with a punch unless it's in a blind hole.

For a DIY fix, that's tough because the shaft might be hardened steel, and a drill bit won't bite into it. I would scuff both surfaces and use a strong two-part epoxy like JB weld if I was 100% sure I never wanted the cog to be removed from the shaft ever again.

Sure you can. As long as the outlet and the wire are rated for the intended load, and the environment they are to be used in (wet/dry.) Also grounded properly in case of metal faceplates (which OP did.) Stranded wire is fine.

Which code? Care to share the reference?

Cool. Go up to a Hasidic Jew and ask what Kosher actually means in a modern context. They'll win a gold medal at mental gymnastics every time.

My favorite is it is absolutely forbidden to shave your beard. Razors are absolutely forbidden. But since electric razors are technically "scissors", it's fine to trim your beard down to the skin.
