I needed to hang a large, 30 x 30, corner cabinet that SWMBO had me
build. I decided to use the angled cleat method hoping for maximum
strength since a TV will sit on it. Anyway...

I angled the blade on my right-tilt saw to 45d and put the fence on the
left of the blade. I was ripping a 4x27 inch piece roughly in half for
the cleats(I didn't want to try and squeeze a push stick between the
blade and the fence on the right.

Expecting that the piece would want to lift up cutting it on the left,
I clamped a feather board to my fence to hold down the piece. So far
so good, or so I thought.

I couldn't get a push stick to help me all of the way with the cut
because of the clamp and the feather board so I ended up pulling the
piece through from the back of the saw.

I know this was wrong, so what is the right way to do this, aside from
buying a new tool.
