While driving home across the Frist Avenue Bridge a big truck passed me. My window was down and I found myself listening for the sound of chains rattling. Then I wondered what the chains on semis were for. Then I thought about how strong chains are, yet flexible . Next I wondered if I could make chains out of tin. Strips could be cut and then they would have to join some how. Eyelets? Too impractical. Flaps that pinch the ends together, nope. Tab and slot? YES!
Thinking about how to improve them. Cutting the strips uniform lengths then using a wooden dowel to make them more round would work. Hum, so much to think about.
