I was a a woodworking show and was amazed at the things that the grip-tite demonstrator cut on his tablesaw- 3/8" x 1/4" x 8' piece cut in half lengthwise-pulled out of the saw by an 8 year old passerby, a warped piece of plywood 4' high rabbeted perfectly on edge, 1/8" x 3/4" strips 6 feet long cut as fast as he could push wood thru the saw.
He could let go of any piece at any time- and got no kickback. He must have cut 30 cuts while I watched
The set actually works! it takes me 10 seconds to setup feeder wheels that pull wood to the fence and stop kickback.
I guess they aren't new, but every tablesaw should come with them.
Anybody else out there use them?
