I use a modulating rake technique to relax the toothline at toe and heel to guarantee smooth action with an aggressive cut. Here’s how:

Rip: I start with a 15-degree rake at the heel for the first twenty teeth, then modulate to 10 degrees for the next twenty teeth. From there, I rake every tooth is at 5 degrees for an aggressive cut. I add five degrees of fleam on every tooth (regardless of rake), which reduces tearout on the opposite side of the cut. The rake relaxes again in the same manner at the toe end of the saw. After conducting the initial filing to set a consistent rake, I then rejoint the saw, establish 20-degree sloping gullets, and file off the points without shortening adjacent teeth so that every tooth does its duty.

Crosscut: The rake modulation for the first forty teeth goes from 20 to 15 to 10 degrees at the heel end of the toothline, then I reverse that for the last forty teeth at the toe end. 20 degree bevels per tooth, and 10 degree sloping gullets. Though ten degree rake for the majority of the toothline is an aggressive cut, It achieves a surprisingly smooth finish on the wood.
