I recently purchased a Dewalt 788 and while reading "The New Scroll Saw Handbook" by Patrick Spielman, I saw a picture on page 127 of the way my blades look after I tighten then release them. My blades were bending art about 30 degrees about 1/2 inch from the end. Mr. Spielman stated that this is the result of a "poorly designed suspension system." I felt that the Dewalt was a well designed machine so I investigated and found that the left pin was not screwed far enough into the blade clamp housing to protrude in to the clamping area, An extra half turn on the pin and it is seating properly now. Well, sorta. I did take the pin out and sand it a little on some fine sandpaper to make sure it had a flat end where it contacts the blade. Just thought this might help someone.
