Happy Holidays
I could use the group's help. I've been experimenting with finger (box) joints using my tablesaw and Freud stacked dado blades. I've been using a 1/4" stack to dado 1/4" wide, 3/8" high finger joints through 1/4" plywood. Every cut burns the wood and lets off some pretty serious smoke and stink. I've tried slow feed and moderate feed to control the quality of the dado cut and not overwhelm the motor. Tips of the dado blades getting a rusty color to them as well. Its not rust as I baby them and keep them safely stored when not in use.
Is plywood susceptible to burning? Am I killing my saw and blades? Any advice to cut these joints correctly is greatly appreciated
