Today I was cutting some 6 and 7 inch legs for some chairs from some 2X2 poplar stock on my Hitachi sliding miter saw. I was not using a stop, just measuring and cutting, but kept noticing the blade was binding or catching at the bottom of the cut. On the last piece I was cutting about 2 inches off the end so the piece was about 9 inches long. When it got to the bottom of the cut it grabbed the piece and sent it flying, backwards fortunately. I checked the alignment of the saw and fence and it was in good shape.
The blade was a Forrest Woodworker II. It has been in the saw for a while and has cut a lot of wood. It still seemed to have a good edge. I changed blades to a fresh one (not a Forrest, can’t afford more than one) and the binding quit and the rest of the cuts went smoothly.
Obviously the blade was the problem but what happens to a blade to make it act that way? What I don’t understand is why it worked well yesterday, but not on the same type cut. I know I should use the hold down but didn’t, no excuses.
