Slitting saws - is there a beginners guide?

Tom, My reaction time, especially when I'm monotonously slow feeding by hand isn't quick enough to avoid problems. Let's just say it's my preference to use a key if the saw is equipped with a keyway. I mean the makers of quality machine cutting tools aren't stumbling around putting features into their product if it's wiser not to use them.
Just my take. Please don't consider it to be criticism, I admire the job you did and the skill it required, especially on the treatment of the last slot. I know that would have been my undoing.
