I think that's why they get removed ......

The whole thing was designed/engineered by someone who probably never used a table saws, ... I donno? Once the guards are removed they get hung on the wall, stuffed in a draw or shoved to the back of a shelf, never to be seen again. I had removed mine for years until I finally "got it" about the whys of kickback. they were always "in the way" and I couldn't see the blade easily, and they were too wide for some narrow rips. Now, after my mods, I love them!



Now, I currently made a 3 piece "sandwich" of 1/4" plywood and an 1/8" ply in between them with a single pivot bolt and a friction fit. It will stay in any position I locate it from the friction from fully up and out of the way to down and in front of the blade. I'll take a photo of it.

I absolutely hate to see threads like this.My deepest sympathy goes out to the injured man and I really hope we all think of him every time we adjust a machine for a new setup.I also hope we all think to take sensible precautions to be safe and don't touch the switch until we are certain that we are safe.Another ten seconds to re-check is a small trade off considering the alternative.The suggestions for safer ways of doing the job might just inspire somebody to make a few changes that lead to avoidance of a nasty accident,so it has to help to keep posting them.

Redesigning the blade cover/guard.....

The friction type blade cover makes sense to me since it doesn't rely on gravity or linkages to move up as the material is fed under it. The operator determines the height it's set to and because of the shape, it will get pushed up to the exact height needed as the material is fed under it.

Some advantages are:

It prevents the hand or fingers from brushing a spinning blade when lowered. It's always in place ready to be used. For those who insist on watching the blade actually cut, it could be made of clear Lexan rather than plywood which was essentially a mock up to test the concept.

As an engineer I worked for someone who was also a woodworker.

I come into work on a Monday and manager has three of his fingers wrapped in gauze. After questioning he told me that he got his fingers into a dado blade. He was doing a climb cut (??? and shudder) with the dado blade. Obviously it just pulled his hand right into the cut.

I noted that he had just bought a 3¼ HP router and asked why he didn't use that. His answer was that he didn't want to take the time to read the instructions.

He wasn't a really good manager either.

I am trying to understand how the accident happened. I read about dado, but I also read about taking off 1/4 inch from a 3/8 inch piece of 5 inch long wood, and discussions about a blade cover, which doesn't make sense to me in the context of a dado cut.

Was the person pushing a board over the top of a dado stack when it kicked back, ejecting the wood, and leaving the pushing hand exposed to the blade? If not, can someone help me figure it out by providing more details?

How do you do a climb cut using a table saw and dado blade? Feed it from the rear? Talk about not reading the instructions....? All the climb cuts I'm familiar with are on the router table or hand held router.

Not to start a segway debate, but a smashed thumb, slice from a chisel, or a screwdriver poke are typically recoverable, and are not usually career-threatening. Dismembered fingers, not so much.

But there is still common sense, and safety protocol on the hand tool side. Keep body parts behind the blade. Don't cut toward you, keep blades sharp, etc.

I was at a carving "work and learn" type of session. There was a dad and his 10ish boy, both carving their own projects at their bench. Dad left the area for a couple minutes. The kid turned his gouge around so the nasty end was toward his stomach, and began gouging with all his might. I had to step in and explain to the kid what could happen if he slipped, until his dad returned.

I did not see "table saw" mentioned. I wonder if it was a radial arm saw?

Dado blades go on saw arbors.
Dado bits go in router collets.
So, I assumed it was a saw.......

i'll add one that will make people laugh.
i'm a retired CG aviation structural mechanic - i worked with aluminum among other things.
i had a chief that was drilling a hole in aluminum. the piece was small so he held it in his left hand. zip, thru the metal and into his hand. i know, not funny.


the safety officer was asking the chief how he drilled a hole in his hand, so the chief showed him how he held the metal and how he drilled it. and yes, as he was showing the safety officer, he did it again!! drilled another hole in his hand! the really sad part, is that he was a senior chief structural mechanic!

There's an old principle ...

They called it "The Peter Principle" which was that people get promoted to a level of incompetence or close to that.

https://en.wikipedia.org/wiki/Peter_principle


People who are good at browning/schmoozing/ kissing their way up the ladder eventually get their just rewards and become upper management where they often destroy the very insitution they worked at for so long.



There are stories like that one above involving loaded firearms also.......

Just saw this post. I hate it for this fellow woodworker. However, just my opinion, but in general, the most dangerous thing in a shop is not a tool, it’s complacency. We become complacent and thus do things we wouldn’t have done otherwise.

I personally won't even look at my table saw or jointer unless I've had at least 3 beers to relax me.

Just me being me and not trying to be you.

It's always better to be relaxed on the way to the ER.

Some medications that make you relax also make you drowsy, and say right on the container "Do Not Take While Driving or Using Machinery":
