no i didnt crown it, i basicly copied the style of the wheels on my horizontal bandsaw, it has metal wheels and no tires or crown, just a shoulder on the back like mine have. they are made the right width so that the solid part of the blade will run on the metal and the teeth will be over the front not touching the metal wheel. atleast thats the plan but im open to ideas, im just copying what i saw on another factory made sawmill, a much larger one that used blades about 3 inches wide, and also copying the wheels on my horizontal bandsaw, but alot bigger
