This is some dry walnut picked up on ebay. There are some tiny worm hole that I didn't have to pay extra for . It's about 10" and has one of three coats of (this one's for you Bernie) wipe on poly...I finally broke down and bought a can . I was able to squeek my Forstner bit all the way thru from both sides but did order and extension. The groove in the top will be filled with crushed stone when it gets here. Cheers!
