I have two of these, one is Teak and Holly and one is Teak and Maple. Each are 40", with 1" straight bore hub. If you need a taper, Edson sells an adapter.
Each is $495, and if you don't think that is a great price, call Edson for a quote and I think you'll see what a deal these are.
These are in Maryland, near Annapolis. Due to diameter they are expensive to ship, like almost $200 UPS ground, just so you know. If you want one shipped, I'll charge only what it cost.
