If you don't mind sharing, what does a burl like that cost? I've seen whole burls sold by the pound, but I imagine once it's cut it's probably not sold that way.
I don't mind at all. Unless you are buying burls that have already been blocked out for turning blanks you're probably still going to end up paying by the pound. This particular burl was 25 lbs dead on at 16$ per lbs, so 400$ total. Most major builders charge at least 300$ for the addition of a burl top this nice and even then a full one piece top is very rare.
I figure at 2 1/2" I can get 4 or 5 full tops from this burl. Now I may or may not charge a full 300$ per top but in the long run it will pay for itself and best of all, I get a beautiful burl top for a personal bass.
