Hello! I'm just starting--havng fun with little projects like pens and pepper mills. I turned a pepper mill from a green piece of osage--the mill turned out nice, but now that it's been sitting for a few weeks, it's developing cracks. So now I'm worried about a piece of claro walnut that I'd like to turn. Both were covered in wax. I've turned the walnut to a cylinder but left the wax on the ends. It's been sitting a week or so. Is there a rule of thumb about how long the wood needs to dry or something I can do to prevent it from cracking. I thought the osage would be ok since the center was drilled out and the walls were relatively thin in most places. Both pieces were 3 inch square turning blanks.
