This piece of walnut laid in my shop for 8 to 10mos, I don't know how long Gary Max had it before I got it, I started to turn it and it cracked--in two places!!!!! Top to bottom center [:(] but I stayed with it and completed it. It is 5" X 8" with 8 coats of wipe on polly. Its 3/8ths" thick. You can see one of the cracks in the back.
