I just aligned my bottom blade holder with the top one and its like I have a new saw. I moved the bottom blade holder 1/16 of a inch outward by slotting the two side plates and moving the frame work out. I don't know if all Dewalt 788 have this same problem but mine sure did. It seems that they would check this during the manufacturing of the saw. I have used the saw for over 6 months just like it came out of the box. Believe me, check yours and do the fix, it well worth it and it takes about 10 minutes.....
