I took a couple of cross sections of down/leaning Rock Maple (I think) from the woods near the house to try making a kuksa. I don't know how long it was leaning. When I got the pieces back to the house they both looked like the log on the right. I stripped the bark, stop cut, then split off pieces to form the handle and did some preliminary shaping. A day or two later I get the huge split you see in the piece I started working. I'm obviously doing something wrong. Am I taking it when it's too green? Not green enough? How can I tell? Am I storing it improperly? Should I treat it somehow? (Boiling?) I'll take any help folks can offer. Thanks in advance!
