Here's a few cool boards I've come across lately and I'm a little stumped because I have never encountered these types of boards. At first I automatically assumed the boards themselves were made from aluminium but I had a surprise when they started sticking to my magnet. I managed to find a pdf file on them but there is no mention of the makeup of the boards. Just wondering if anyone has any experience with these, keep in mind I don't refine so any refining suggestions would be useless to me at this time but could serve a purpose in the future. What I can tell you though is the fingers come off in flakes like paint chips. Butcher and Geo have gave me some advice already but unfortunately i'm shooting in the wind.I do appreciate the info from the both of you just not ready yet. Any ideas on pricing, or if you guys see some good components I should be removing or what the metallic board is are welcome.
