For the first time in 20 years of using a table saw, I got nailed by the
kickback genie. I was trimming 4 short (5"x5") boards for a project,
taking 3/4" off one of the sides. I trimmed the first three against the
rip fence without a problem. When I use the TS, I never stand directly
in front of the blade. On this cut, I was on the right side of the
blade, feeding the work by hand. On cut number 4,I must have turned the
board a fraction and the blade kicked that sucker back on an angle and
it caught me right in the heart. Scared the crap out of me. On
reflection, I shoulda used my featherboard and a push stick. Lesson
learned.

Bad call...

W/L = 1 w/ small pieces is recipe for causing what happened.

Use a sled instead.

Featherboard, holddown piece, and pushstick.

Congrats on your luck.

No splitter?

Still, a warning shot is good thing.

(And 5" violates my rule regarding proximity of body parts as a push stick).

Glad to hear that you were not badly hurt. And as a reminder that
standing anywhere behind the blade is in the danger zone.

I have a rule for avoiding this type of problem, that I teach my students...
Might be good for you, too.

With the blade set at the right minimum height, measure the distance along
the blade that is above the table. Let's say 5 inches is what that
measures. I say that the board being cut has to be the length of the blade
plus half of that distance added back on, so 5 plus 1/2 (2.5), so the wood
needs to be 7.5 inches long, against the fence. The fence also must not be
set much further from the blade than the length of the board.

Use the miter gauge if it does not fit the above conditions, and of course,
never use the rip fence and the miter gauge at the same time.

The smaller the pieces you're cutting, the greater the danger. I cut a
small piece of 1/4" luan plywood a few years back and the cutoff hitched a
ride over the top of the sawblade, and crossed from right to left side
until middle and index fingers of my left hand stopped it (I'm right-
handed). I needed a bit of plastic surgery to repair a tendon. Not quite
as good as new now, but serviceable. Just didn't like the whole
experience.

Standing anywhere behind the **wood**. I would love to see you stand in

Jim in NC,

I don't quite get the "The fence also must not be set much further from
the blade than the length of the board." Assume you are ripping a 2X4 that
is a foot long. The fence distance could not possibly be even close to the
length of the board. If you are cross cutting, setting the fence at the
board length would mean the board misses the blade.

Where did I get it wrong and what is the correct interpretation?

TIA.

You would Not cross-cut a twobyfour using a fence--at least not during
the cut. Someone else may be better able to describe your options.

Right. The fence cannot be (usefully) set further from the blade than the
length of the board, so you're OK. If you're cross-cutting, don't use the
fence! Use a cross-cut sled, as has been said here a number of times.

Where did I get it wrong and what is the correct interpretation?


The problem arises when the board twists when it's in contact with the blade.
It's a sure way to have it come rocketing back at you. If the board isn't
longer than the distance from the blade to the fence, there isn't enough of it
on the fence to keep it against the fence.

I do, when there is a need. With two power miter saws and a 14"RAS sitting
around, there is not often a need.

I will try again.

If the saw blade is out of the table top 6" along the direction of travel,
the wood being _ripped_ should be at least 9" long. Doing this keeps
enough wood on the rip fence to keep it from turning sideways while it is
beside the blade, which of course would cause a big kickback.

The second part of the rule is that if the piece being ripped is 9" long, it
should not be ripped more than 9" wide. Doing so would allow the wood to
again turn sideways, causing kickback.

I know, there are some exceptions for the experienced woodworker, but this
rule is to keep 14 to 18 year olds from doing something drastic-bad. They
can learn to ignore my rules after I am not responsible for keeping their
fingers on their hands.

That work for you? ;-)

Thanks. Now I understand. I initially thought you were using the fence
during ripping. I now understand that it simply serves as a reminder to not
allow too wide of a rip, crosscut sleds not withsatnding.
