I made two mallets. Large mallet was from a 10/4 x 12" piece of Bubinga that I had laying around for years. I glued up 2 pieces and turned it to about 4" in diameter at the head and sawed waste at the handle and turned it round. Small mallet is hickory and white oak. I glued up 3/4" pieces of each species first was hickory then white oak etc til I got to about 3" in diameter, Turned it like the previous mallet.
