This really cought my eye. When timberframing a durable mallet is a necessity, at times heavier the better. I made large ones out of ash and maple but they always split eventually. I reuse the handle each time. The last one I made I put threaded rod with (can't think of the proper name now) flanges nuts used backwards, the flanges out. Still split. Have sense obtained some 5x8 black locusts I plan on turning on the lathe with metal bands to prevent splitting. Just may have to try this too!
