This may be "old hat" to most of you, but considering the horrors of kickback I've heard about, I think it's worth watching.

Comments?

Good video that really illistrates the danger and the mechanics of how it happens.

Also found this one for a fence addapter that shortens the bearing surface of the fence. http://www.youtube.com/watch?v=d7QXIN2X ... re=related

If you check out Niki's posts in the How To section, you can see that his TS has a very short fence, that only extends to the center point of the blade. This allows the work piece to move further from the blade on the backside of the cut. :wink:

Of course, the best thing is to use feather boards, and good push sticks that help to hold the workpiece down to the table.

Interesting but I wish he had mentioned cutting boards that are cupped or bowed. The rocking motion from doing that can be very hazardous also.

That sounds like the reasons listed in old Unifence adds.

His DVD's sound interesting.

Yeah, the closest I've ever had to a kickback was with a bowed 2X4. Luckily I was using feather boards, and had a wimpy TS at the time. It just started bogging down the motor and created a lot of resistance to the feed. It felt like I was loading a spring, and knowing a little about springs I figured the best thing to do was to turn the saw off before something spung back in my face. I think that had it been a more powerful saw I'd have eaten that board before I'd felt it coming on. I did learn quick to square up my timber before putting it on the TS.

I do like the short fence idea and may have to incorporate one into my fence.

My only table saw accident was caused by ripping a piece with a big knot on the down side. On the top it looked like a really small one.
the knoT broke loose and flew back into my finger that was holding the push stick. Broke the tip of my finger back halfway up the nail. Two hours of surgery got it back to new, but not a fun day.

WATCH THOSE KNOTS!

You can also get kickback from so-called "reaction" wood. The kerf of a board with a lot of stress in it can close up on the blade as it is being cut, pinch the blade, and get hurled back. Anti-kickback pawls and a blade guard can usually help in that case, but not always.
