Before anyone suggest just buying some good quality steel, or gongs I have to point out that where I live it is very difficult to get these materials and shipping gongs from the US is not even thinkable. Last week I sent out 30 odd email to steel suppliers and the like to get 1 reply, who asked for more details then never got back to me. Frustrating. So, I got to thinking, could it be that hard to get a half decent temper on some of the mild steel that is widely available here? I have a large furnace and a wood fired oven that can both provide plenty of fairly stable heat, surely the worst that could happen is that a gong is too brittle and cracks??
