Hello all. I have had this saw for nearly 2 years. From the beginning I found that the blades don't stay in the clamps. I have not broken this many blades on any machine. I had the basic Delta 16", Dremel, and DeWalt 788. But the real problem appears to be that when I stack cut 3 pieces of 1/4" oak ply; the bottom piece either comes out larger or smaller then the top piece. It is so frustrating. Initially I had taken it in for a checkup and was told that there is nothing wrong with the machine. Actually I was told that because my saw is not on a concrete floor that is why I am having these issues. I cut the wooden floor and laid down concrete. Lo and behold ... Still the same problems. Any suggestions would be appreciated. Thanks all.
