Thanks LHN/E, this input should point me in the right direction. Yeah my boy actually inspired me a bit on this idea. We have all this scrap rebar kicking around just taunting us. I hate waste and the kid is pretty good at re-purposing stuff. We even came up with the idea of using a disassembled non rebuild-able sbc engine block as a makeshift anvil, at least until I come across the real deal. Just think of all the shapes you can make hammering on that sucker. Then when we are done we can fill the cylinders with dirt, throw some seeds on top, instant "gear head herb garden"
