      I've machined silicon bronze shafts for a boating buddy and found it
      fun. It makes very pretty ribbony swarf. IT's tough, similar to
      SS. For slitting saws just use any speed/feed table and use the
      diameter of the saw. With a 3" saw, you'll end up pretty slow. HSS
      should work fine, especially with coolant. If you don't have flood
      coolant, squirt it frequently with some light cutting oil. I often
      run slitting saws very slowly so that I can just squirt coolant onto
      the top of the blade and let centrifugal force feed it in.
