Got my new ALX "Deputy" and decided to switch some reels around. One reel, I knew what was on it, but not the other. Could be FC or Copolymer. If it was FC, I didn't want to just put it in the recycling bag, so I figured out how to wind it off and onto an empty spool using my Makita drill. That worked great, but I don't know what the stuff is. Both reels were full, indicating that they've not been used much, if any. And yes, I'm being cheap!
Has anybody devised a foolproof way to tell if it's FC or Copolymer? I'm pretty sure it's 10 lb test, and I put the micrometer on both. One was .0110" and the other .0105". I don't really think the .0005" is something I can trust to say that both are the same (FC). Anybody tried seeing if they can take a sample of FC and say for sure that it sinks, while a similar length sample of Copolymer (for certain) floats? I'm thinking surface tension might make that test invalid. If it does work, would I drop both onto the surface and wait, or would I weight one end of each sample and see if the free end sinks or floats?
Any other ideas, short of something scientific, like spectrum analysis or chemical analysis? The first half of the word "analysis" makes me nervous!
