Thanks for the heads-up, I'm not much into bananas and rarely drink milk but I'll check it out These cramps really seem like a nerve thing- my toes get locked in a painful curled position and a hard spot wells up in the bottom of my foot. If I massage the heck out of the bottom of my foot, my toes eventually release.
You need to get the metal particles pressed down into the carrier before it gets too hard to do so, as you've found out I never wait longer than ~45 minutes The aluminum plate will buff out to the highest shine, but is more finicky and delicate than the stainless steel
All you need is a space between the multiple exclusions, for example I collect cups made of cow horn but don't want to wade through all the carved yak horn cups from China, or the pointy "viking" or "game of thrones" ones, so I search for "horn cup" -chinese -viking -thrones
I have boxes and boxes of stuff that isn't actually junk, but that I'll probably never use. Some of it is somewhat valuable- like an original radio for a '72 BMW or NOS parts for old turntables and tape recorders
