How about pallet rods, under organ supplies in Schaff Catalogue Item #706.
Maple 3/16"X 5 1/4" long.

Is there any consensus on the length of shank that would need to be inserted/glued into the hammer butt for adequate strength/stability? Seems to me one shank diameter would be too little, maybe two shank diameters at a minimum - that would be 3/8"? Of course, more would be merrier, but if I am to use these shortie shanks, I may not have that luxury. Any thoughts?
