I recently tried to make a sign by tilting the table of my DeWalt a few degrees. Using a #2 blade, I cut a few letters and they moved out about a quarter of an inch, which is what I wanted. Then I thought I'd try using a spiral blade. Leaving the table at the same angle, I cut out the same letters. To my surprise, the letters fell out as though the table were set at 90'. Can anyone explain why this happened? I am so confused......

apopj, I would guess that the kerf of the spiral blade is wider than the regular blade. Try making a cut with a regular blade and another with the spiral blade and compare the width of the kerfs.
To get the same effect, you would have to tilt the table more. How much will depend on the width of the kerf and the thickness of the wood. There are posts on this forum that should help set the tilt and there might even be a formula to calculate the required tilt. If all else fails, make some test cuts with different tilts.
Good luck,
Jim
