Dinner bell triangle set with Ringer and Strut to hang it from. The ringer hangs on the triangle when not in use. The strut is probably the largest "hook" I have made and the larger curve is the size of the horn on my tiny anvil. I haven't found much difference in sound quality from quenching the triangle in oil, I wonder if that's just something people say?
Regarding quenching - some alloys don't harden well so I could see it having a minor or no effect depending on the metal
