Cut some hickory into 1/2" hickory squares, 30" long. They are still kinda green, but all are slightly bowed. I'm using a power drill to run them through a metla plate with holes drill in, but should I wait for the wood to season? Out of trying 7 or 8, only two came out perfectly, and one came out close but still with a nasty gouge- and I'm not using the ones with knots or problems in grain. Should I let them dry befroe I continue, or continue as they are easier to straighten?
