I have no idea on what material to use. At almost 3" diameter, I'll have to go and buy an off-cut from somewhere. The only material I have on hand in that size is 6061 and a large length of ø4" 1018.
I had thought of redesigning it so that the two arms pivoted on screws, with a spring between the ends to prevent drag. This would eliminate the need to find the right characteristics and would make it easier to machine. The base and arms could be machined separately then and assembled in place.
