I finally got back to my shop after surgery and other health issues. I just got 40 feet of Black Walnut and have 40 feet of cheery and the same amount of maple coming. If I cut this up in 6 feet sections, seal the ends, and store in a dry area how long can I expect it to last before turning? I'm going to work a few days making blanks and then a few days turning green bowls. I made a tooth fairy box and Christmas ornaments for a man's little girl and he blessed me with wood. This blank will be the largest attempt to date and as large as my lathe can handle.
