Not really a skill question for your video, but what do you do with your steel or aluminum shavings from fabrication?

Where would I look in a medium sized city to find shavings of either of these metals for a science project? Locksmiths?

Do you use any 3d printing in your shop? How do you balance shop set up and organizing time vs using time?(I've seen people spends years making the right shop set up and then never really use it) How does someone focus on achieving goals vs preparing for unstated goals. Do you clean up right after a job is done, when done for the day or just leave it where it is and wait till you need it again and then go look for it. Sorry if you covered any of this before. New to Nostr and not seen your stuff before.

Do you have any calibrated body parts? Sounds weird but I know my pointer fingernail is 1/2 inch, first pointer finger joint is 1 inch, 2nd joint is 2 inch, finger tip to knuckle is 4 inch, extended thumb tip to pointer finger tip is 7 inches and spread thumb tip to pinky tip is 9 inches. With a combination of these between two hands I can get pretty accurate measurements pretty quickly.
