Hey Toni. The walnut top I'm working on is smaller than yours but doing basically the same process. Not sure if it was mentioned before but I never leave something this size laying flat on the bench overnight as I've had a couple twist, particularly as I get closer to both sides being flat. This batch of wood is what I call Urban Lumber since it came from my neighbors front yard next to the street and even after slow drying for ~2 years it would move after initial machining.
