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


Don't ask me how I know this, but you will get those results if the
blades or chippers are on backwards. Plywood tends to stink anyway,
and chip on the cross-cuts, but it shouldn't be burning. My Freud dado
cuts clean as a whistle with no burning ever.
