I agreed to turn a carving mallet for a fellow woodworker. He brings me green ironwood that is about 3"-3.5" in diameter, with the pith. He says he doesn't care if it cracks but it seems like a waste of effort unless I can deal with the pith. Wondering if I can just drill out the pith and replace it with a dowel. Might even be better to make it 2 pieces and just make the head from ironwood, drill out the pith, put a tenon on the handle but I'm worried the handle will crack or break as the wood dries. I'm open to suggestions, advice.
