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.
