I'm not sure what I did wrong here but boy did it hurt! I think I backed up a bit with the blade spinning. Also maybe because I was cutting so far from the fence. My first pass was good just not uniform in depth. About 2ft square 1/2" ply shooting back at me hitting me just above where it would have hurt a lot more. 3HP saw. Cutting 3/4 by 3/16 dadoes for dividers in a plane rack. Not real experienced with dadoes Pictures now posted below.
