I was making my first insert for the table saw for a 15/32 dado which I seem to use a lot. I put the insert in place and put a piece of hard wood on top. After I started the saw I decided to also use my jointer push pad on top of the scrap wood.
I raised the blade through the scrap wood and shut of the saw to take a look. I decided to make the cut a little deeper. Placed the scrap over the blade so the blade was in the same grove and then pushed down with the push pad and turned on the saw. The dado grabbed the scrap board and somehow moved it out of the way and pulled the push pad into the blade.
I don't under stand hoe the pad ended up under the piece of scrap but it cut a good 1/2" deep by 15/32" gash in the hard plastic. My fingers are very grateful.
