Thintz should be given some kind of worldwide recognition for making that video (regardless of how crazy it was to do)
This should be put on a DVD and distributed with EVERY table saw and high speed cutting tool, shown at safety courses and lectures, shown at colleges and schools and generally hailed as the ultimate WARNING

How many fingers do you reckon he'd have lost if he hadn't been waiting for that to happen ?
Sheer luck that he lost none despite being ready for havoc

+1 for the inclusion of a DVD. It's quite bonkers how Joe Bloggs (soon to be John Doe) can walk into a shop and buy a 5hp saw, spindle, PT, chainsaw etc. with ZERO experience or knowledge!
I must confess I took the crown guard and riving knife off the other day for a brief operation... and boy did it make me feel uncomfortable 8-[
From previous working experience it still amazes me that our cousins on the other side of the pond rarely use crown guards or riving knives. One experienced (50 yrs +) and talented woodworker's opinion was that guards are considered more a 'hazard' as they obscure the blade! ...er... there's always the added benefit of dust ext not to mention keeping the sausages.
Go figure as they say :roll:

Crazy stuff! His fingers got wayyyy too close!
At work we have to do an occasional operation where we remove the riving knife and crown guard and cut half way thru a 214mm board, flip over and complete the cut. Its something I have complained about doing ever since we did it the first time. I know it don't matter how often we've done it... but I am glad to say in 2 years I've only done it 4/5 times and its a two man operation using a sliding carriage also. However, the next time we have to complete that operation (which I think maybe in the next month or so) I am pleased to say we have fabricated a riving knife that can be used in the cutting and we have also made a crown guard to cover the blade and extract as best as possible.... although it is still hard to do have a 150mm high blade and a 214mm thick panel, it will be much better than the current situation.
AND after that video.... Well, I'm not going to take the decisions regarding saw safety lightly! -Although do think it would be hard for a 214mm 8x4 sheet to kick back, a nasty accident is still waiting to happen without precautions taken.

Nice one Flynnwood - I saw that earlier (and it looks fantastic) but was so gobsmacked by the video I posted that I forgot all about it
Wonder if the guy who developed the saw stop device can make something that will detect a flying piece of wood about to enter your skull

Jelly - I quite agree. An analogy would be to have bullet proof vests issued to all family members whenever a gun is sold. Well, it would prevent injuries, wouldn't it?

The best use of saw stop would be to have it on your machine with out you knowing. Atleast then you wouldn't be taking risks thinking a safety device would save your sausages

I have been using saws for 35 years & that vid made my blood run cold. I remember my dad cutting a short piece of wood on an old startrite 8" table saw, it dug in & flicked it up into his face. The chunk of wood hit him right on the chin & nearly knocked him out.
Another friend did something stupid with a big wadkin dimension saw & lost half his hand.
Still if watching that vid makes someone think twice it will have done its job.

I, too, filmed an example of TS kickback and I show it on one of my DVDs. But I used a much bigger workpiece and my fingers were nowhere near as close at that and it was quite scary enough, thank you very much.
I have had a kickback accident only once on a TS. It was my first machine, I'd had it just a few days and I new absolutely nothing.
I was cutting a piece of 3mm ply freehand, no guard or RK and the edge of the board hit my arm. I had a lump on my arm like a Tom & Jerry cartoon. I felt sick in my stomach and I still have the scar on my arm. It taught me a lesson.
Kickbacks are not trivial accidents, and have even been known to be fatal.
Stay safe out there.

My kickback experience was my own fault, taking a known risk, 20" square piece of 30mm worktop, quite a heavy lump, I mishandled it and in a fraction of a second it received a deep curved groove and was flung into my belly. It didn't particularly hurt but it did cause me to check for a wound, and to be more careful in future.

Sorry to read about all the accidents, but that's what novices like me need to hear/read/see
I use my saw as it was given - no guard, knife or proper fence and this made me sit up and gasp, your experiences just show how often this happens

After watching the video I was pleased I had had a light breakfast, Den you have got me worrying again.
I use my saw only without the blade guard when using a sled but I am still concerned about a kickback with a sled, mine weighs a ton and that I am sure would kill if came off table.
Anyone had a kickback using a sled and flight?
Also I have got around 4mm off the top of my riving knife for those other jobs.

you should be much safer with a sled DW- it is the equivalent of a compact sliding carriage, and has no fence to trap a workpiece against. If you wanted to ensure that everything stayed exactly where you put it, then a toggle clamp on each side of the cut line would do it nicely.

In my previous workshop I had an 8x4 sheet of 1/2" MDF as a tool board above the bench. I had a piece of wood about 2 x 2 fire back out of the saw and go right through the MDF and the plasterboard behind it from 5 feet away. I was fully aware of kickback and have always stood to one side, it still happened and left me shaking. It happens so fast, as shown in the video. You think you're prepared for it....you're not! Take care out there friends!
I'm not convinced it would fire a sled out the same way. It could still do some damage though.

Its if the sliding bars should lift up for some reason off the mitre gauge slots and twist, what would happen?

It would have to be an unusual situation for that to happen. Surely the idea of a sled is to avoid this type of thing happening as much as accuracy? I can only think of one other option to guarantee safety, motocross armour and a helmet.
