Decades ago, and for a good number of years, Ray Fadden made stretched rawhide drums using round pasteboard containers with metal support rims. Occasionally he used round wooden containers. I recall that he also used a metal barrel on occasion. He used deer hides and cow hides stretched on top and bottom. He gave many of the drums away, and a number of them are exhibited at the 6NIM. One day, as I recall, he wondered if he could make a square drum. Attached are photos of some of his round drums, and one square one.
