I was making a cutting board the other day with my grizzly 1023sl with a freud 50 tooth combo blade. This is my first project on this saw. When i cut the thinner strips the leading and trailing edges were tapered. The smallest strips were about 3/16" wide. It happened on the wider strips (1/2") but not as bad. What could cause this? the strips were about 16" long and the taper was about 2 to 3" front and back. The middle sections were fine. These were rip cuts. Thanks !!!
