While building a cabinet I had to cut some dados using my TS. I taped
up the area to be cut with blue tape to prevent chipout on the plywood.
Where I had problems was the wings on my contractor saw are not
chamfered at the leading edge the way the main part of the table is.
This sharp edge caught the tape and pulled it away, balled it up, etc.
So I had to tape a dado, make the cut, remove the tape, tape the next,
make the cut, and so on... This sharp edge does cause some resistance
when cutting large pieces even without tape.

Should I file/grind a slight chamfer on the infeed side of my wings?

PS I have a router jig to make dados similar to this:

I just didn't make it big enough for a 2' wide panel. I will be making
a bigger one for the dresser I plan on building next.
