I was attempting to cut a 4'x8' sheet of 3/4" plywood in half using my Ryobi ZRCSB133L circular saw along a clamped straight edge and when I would get about 1/3-1/2 way through the cut the saw would start bogging down and would appear the cut starts turning into the straight edge. My initial thought was a blade issue but a new blade did not resolve the issue. I can make smaller cuts off the edge of the board just fine but when cutting anything towards the middle (same issue with a 30" cut) I run into this.
Now the work tables i had the full sheet resting on had about 1/2-3/4" height difference so maybe that caused the blade to bind up? My other thought was to adjust the cut depth on the saw to the proper cut depth as opposed to me running it as far down as it goes (nasty habit of not adjusting that). I could see that helping but before I ruin another sheet I figured I'd see if anyone knows why it could be doing this.
Thanks in advance!
