I thought I would pass on HOW my kickback occurred, so everyone might keep this is mind when working in their shop, or anywhere someone might surprise you.
First off, I do use a splitter for all through cuts, ALWAYS. (Obviously, cutting dodo’s and other cuts require it be removed)
I had just started to rip a piece of wood, the board was almost to the splitter, but not quite. That’s when my wife busted in and startled me. I turned to see what happed behind me and moved the board as I did. That board hit me in the center of my chest. And it HURT.
Typically kickbacks happen when a table saw is being used without a splitter, or better yet a combination splitter with anti kickback pawls on it. The board is either moved sideways enough for it to be out of parallel to the blade, and get bound in, or the board has internal stresses that cause to to close around the blade once the saw kerf releases some of this stress. This is when it becomes a missile.
At the woodworking shows I attended, promoting my product, many woodworkers felt the need to tell me about their war stories, including the various injuries they’ve received on this machine.
I cringe when I see someone using saw saw with no splitter on it. Sooner or later it WILL happen.
I know, the response of many reading this, “hasn’t happened to me and I use the saw all the time”.
Remember it only takes once. and it can be fatal! Either to you, or someone behind you.
I don’t have any statistics, but my guess is 99% occur without a splitter, or combination splitter and abti kickback pawls.
