Rehd,
I bought a new blade from my Delta 14" and at 6tpi it was rough. I got a 10tpi and it was smoother, but you could still see irregular vertical marks. Is it important to eliminate these, or will it come out easily in the sanding when it is on the boat?
Have you had problems with a wide kerf loosing directional stability while sawing?

Also, what kind of fence/jig do you use? Can it handle boards with a warp? I thought I would make a fence specifically for a couple of long but warped boards I have, by cutting a curved fence to match the curve of the horizontal warp. This would allow me to use warped boards without loosing anything to waste. Think it'll work? - Scott E.
