That alone brings it down into the realm of a size I can make without any huge drama should the need arise before I fall over.
And I expect most of what I do with it could be called onsies. :) > As for it maybe being Al-bronze, the one I alloyed up was deep golden > and denser than steel, due to a heap of Cu.
