I have LOTS of A36 flat bar stock, all 3/16" thick, in varying widths and lengths. Way more than I'll ever need. Obviously this is not a high dollar item and isn't very hard to come by, but if anyone is interested in trading for some blocks, bars, or whatever of something more interesting (with you getting far more by weight than I will, up to a large priority box full), let me know. Especially interested in brass, aluminum bronze, copper, aluminum, high carbon steel, and 4140. Also interested in acetal/Delrin, HDPE, and UHMW.
