I would like to know if what I am doing on a table saw is safe.
I have ripped a board to 4" in width. I then have a piece of
3/4" plywood that is approximately 5" X 5" and I would like to
cut this to 4" wide to exactly match (in width) the first piece
I ripped. I am sliding the 5" X 5" plywood through by hand
holding it tight to the fence. Pushing it through with a push
stick does not "feel" safe to me. There is plenty of clearance
for my fingers when I slide it through. However, since the board
is only 5" across, it also does not feel safe to me to have the
plywood fully behind the blade with nothing on eiter side as I
am sliding it through. Miter saw would liekly be safer, however,
I am trying to exactly match the first board I ripped.

Is what I am doing safe or not?

I wouldn't do it, not after a board a few inches wider, and a few
inches longer kicked back on me when doing a rabbit about 5 years ago
and split my right index finger down the middle about 1/2" from the
tip, and that was with the blade only raised about 1/4".
