I'm fascinated by your knowledge of various fastening/affixing hardware (such as a shaft collar, which I didn't know exists but can see its immense usefulness). Did you learn about all these devices from your job? If so, where does someone like me learn about all these various cheap metal apparatuses since I enjoy building my own stuff as it relates to my various hobbies, including but not limited to, climbing/fishing/beekeeping? This type of knowledge would be extremely useful if I can find out where to attain such knowledge! Just looking to be pointed in the right direction so I can get started more easily, such as maybe a couple keywords or search terms to lead me down a deep-dive rabbit hole.

This is chatGPT's recommendations, if I don't hear back I'll just start with this list. 😁
