   A larger diameter blade needs to turn at lower RPM's to maintain the same rim velocity as a smaller diameter blade rotating at higher RPM's.

   Circular saw teeth on manual-fed machines are engineered to perform best at about 120-140 miles per hour rim velocity.

   The 6000 RPM rating is the maximum speed to safely run the blade. It will run fine at the lower speed. 3200 RPM on a 12" blade gives almost the same speed at the rim as 4900 RPM on an 8" blade.

   Thanks Bill; I appreciate the education.  Your explanation makes sense.

   I've found that the Makita stock blade aren't all that bad,
   I'd use it up before replacing it.

   I didn't care much for the thin kerf stock blade. It tended to deflect on compound cuts in larger pieces. I replaced it with a 100 tooth FS Tools HD Mitre saw blade. Made a good saw a great saw.John O'Connell - JKO Handcrafted Woodworking

   We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized.  I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.

   FS Tools is a manufacturer of industrial blades in Canada. You should be able to find a source near you on their website. If you are anywhere near Anaheim I get them from California Woodworking. You won't find them at any of the hobbist suppliers.John O'Connell - JKO Handcrafted Woodworking
