Every time I see this video I get a chill up my spine and goose bumps.

I watched that video until he went to the close-up slo-mo on how close his hand came to the blade – I couldn’t watch that.

It hurts just watching it, knowing what he is going to do before he even starts cutting!

I watched that video a while ago, but it’s impact is still pretty strong.

At the job I just left none of the TS’s had splitters or guards, and they all had numerous mechanical issues as well. I had a piece kick back like he was showing and catch me in the stomach. It was hard enough that I had to take a couple of minutes and recompose myself.

the guy doing the demo is a regular over @ woodnet and he posted this about a year or so ago over there. after my relatively minor 2 stitch encounter with a TS blade 8 years ago, i’ve never allowed my hands anywhere near as close as his came to that blade. his “after i changed my shorts…...” comment about sums it up.

I calculated TS blade tip speed once and if I remember correctly, it’s about 100mph.

Those push blocks he was using weren’t the right kind to use for a table saw either, he failed to mention that in his video, I custom built mine in which places my hand way above where his was and my pushers also have a drop down lip that rest up against the back edge of the board while pushing it to give it a no slip option also helps keep the board plum with the blade and the fence not allowing any turning what so ever.

Yeah, I thought I read once it was about 104-105 mph. Trust me, from experience, its fast and hurts. I took a piece of quarter round I was ripping free (like an idiot) to the stomach. Huge bruise and a permanent imprint of quarter round on my stomach to remind me. Good lesson though.

I just watched an episode of “woodsmith” on PBS…..guess what…..No rivving knife. Now, some dadoes were being cut, and I know theres that whole “safety devices moved for clarity” line, but there should of at least been some mention of the fact.

I have been a painful victim of kickback. I got a bruise on my stomach that lasted for a few months. Luckily my hands were nowhere near the blade…..btw….no rivving knife there either. :-S

Thanks for sharing this. I have a splitter that mounts to my Zero Clearance insert. I’ve had it for nearly a year and it is still in the packaging.

Now I have a new project for the morning – thanks again.

A friend went to the ER a few weeks ago from kickback. The wood got him. 31 stitches on the tops of his fingers. OUCH !

I have not experienced kickback since highschool woodshop 20 yeras ago. Dull blade, and poor fence.
A splitter helps.
The biggest change is that I use straight freshly jointed lumber. The old woodshop used whatever they had laying around. I also use a magnetic featherboard and saw-handle pushstick. And I would never cut a piece that short.
I guess I have all kinds of safety rules that I use, but don’t even think about.

Woodworking is a violent action that produces often beautiful results. As my dad said the more power the bigger the mistake. (when i asked to use his power tools as a kid!) Been looking into retro fitting riving knife attatchments. Appears that they only work with straight cuts?

I experienced kickback once with my table saw and that was enough to make me extremely careful when using it for the rest of my life. Fortunately, I was standing off to the side and didn’t get hit. My toolbox, which was clear across the other side of the room, was not so lucky and will sport a rather large dent for the rest of its life.

I saw this about 3-years ago or so, when I was “shopping” for my FIRST real table saw. I have to admit that THAT kick-back was the reason that I went with “new”, because all of the “newer” TS’s had the required Riving knives. I never did like the over-the-blade blade guards and the reviews on them were the pits. The advent of the tool-less removable riving knife finally convinced me to pull the trigger on a new G0690.

FWIW, this is why I would never buy an old/older model table saw, even though many LJs just love their old “unisaws” and such. Nostalgia is just NOT a good enough reason for ME to ignore this (riving knife) feature in the newer saws. SawStop, on the other hand, I CAN ignore. But that is just my 2-cents…

That is scary! I have only had my TS kickback at me one time. I wasn’t using a riving knife, and the board turned and shot back at me.

The guy was an idiot as he said in the video. To intentionally cause a kick back and using a push block that positions your hand within three inches of the saw blade to start is retarded. I make my own push blocks and the small one keeps my hand at 4” above the saw blade. When a board kicks back it is going to take your hand toward the blade.

I think if more people saw in person how gory woodworking can be, how the senseless slaughter of fingers, hands, eyes and more, are mangled into pate, beyond repair, tool sales would drop.

For mere mortals like me, I pick up the pieces, lick my wounds, and move forward for victory has sweet rewards in the world of woodworking.

Its a good thing I haven’t had dinner yet! My stomach turned upside down !
Thanks for the post. We need to be constantly reminded how quickly we can get hurt.
Like Lee said above, the tip of a 10” blade is running at about 100MPH, or about 145 fps. By the time we realize that something happened , it all over.
Some time ago I did a stupid thing. I was cutting a SMALL piece of thin hardboard on a RAS. I was lucky that I was not standing directly in front of the blade. I heard a bang and the hardboard disappeared. I found it three weeks later, in a closet in the next room. The blade shot the hardboard clean through the sheet rock. I was lucky to come out of this unscathed.
We should revisit that video from time to time.
Thanks again for the post.

His hand came close to the blade didn’t it? Too close for comfort.

I personally think those push down push sticks are the worst invention ever – when something like that happens you’re hands may be away from the blade but they’re at the same level.

he should make another video demonstrating what would happen if the guard and splitter were in place.

I think i’ll reinstall my riving knife tomorrow…

I’ve shared this story before but I was on a job once and bent down to pick something off the floor and someone on the TS had a kickback. My head was directly in line to get hit, luckily my tool bag was on top of the table and took the hit. I was wearing a hardhat at the time oddly enough, but who really wears a hardhat when they are woodworking?
