I am stocking a piece of quilted maple now and it is the hardest piece of wood I have ever worked with. Absolutely gorgeous but difficult, you just have to work slow and take small shaving cuts. Try to take a big cut and it WILL tear out.The customer had been holding on to it for 40 years and finally asked me to build him a gun with it so it is nice and stable. With maple, each blank is unique, you have to check each one individually for hardness. Some are soft, some are hard, it has more to do with the condition the tree was grown in and if it was properly handled after cutting. Species makes some difference, but you can get soft sugar maple or hard red maple, you just have to check each one if you can. It you can handle this piece, try to dig a fingernail in it. If you can make an indentation, I would pass no matter how pretty the wood.. Even better, try to make a small cut with a gouge, that will tell you if it is hard or not.
