The slightest binding with the blade or friction with the top and

He has a rip fence on his contraption. As long as it is as
parallel as your rip fence, then he suffers no greater risk than you
do.
Friction with the top? that has never been a contributor to kick
back. All that does is make a slower cut. Slipping off the saw
horses? There is an inherent coefficient of friction based on the
weight of the contraption and it will require more friction than
that to cause it to slip off the horses. It's not even evident
that the "table" is not secured to the horses, or otherwise
prevented from slipping. Maybe it is, and maybe it isn't.

As for the "inherent coefficient of friction based on the weight,"
I'm lmao at that. I've ripped long boards that were bowed and would
push my delta along the concrete and it's pretty darn heavy.
I thought it was pretty evident the thing wasn't attached, but let's
say it is. It takes very little force to topple most saw horses in
the direction his are set up. Certainly FAR less than what it takes
to move my Delta.

Mike - you need to add some weight to that Delta. I've never pushed
my Craftsman across the garage floor - but then I don't try to force
wood that should not require that much force through my saw,


Yeah, whatever.
Bottom line, you seem to think the operation of the saw in that video
is perfectly safe.

Nah - not that I think it's pretty safe. Not even something I would
consider to be a regular part of my wood working practices. I just don't
think it's a dangerous as has been suggested here.


Nobody ever thinks anything is as dangerous. Apparently there are guys
in here who think their saw's splitter is too inconvenient to bother
with. And that's on a proper table saw. It's all hyperbole until you're
in the ER getting stitched up.

When I see stuff like that in person, my motto is, have the argument now
before there is any bloodshed. Last time, I didn't.
I was helping my producer friend build a studio in his house. His bass
player was there doing most of the work and design. He had a little
table top job-site table saw sitting on the driveway, with the guard and
splitter removed. I didn't know the guy very well so I didn't say
anything. After the guy left, I told my producer friend, "He should
really be more careful as a carpenter if he wants to keep playing bass."

Not two months later, he called me and told my the guy had to go to the
hospital to get his hand stitched up and had months of physical therapy
to look forward to.



I had a similar occurrence on a jobsite. A guy had a saw with guards,
riving knives, splitters, etc. I mentioned to the superintendant that
if I had to have all that stuff on my saw, I wouldn't be able to see
what the hell I was doing. A week later, the guy cut his hand open on
his "protected" table saw. Out for 2 months.

Robert, the guy who has gone 40 years without a serious accident on
table saws with nothing but a blade and a fence.
