Apparently you still don't.
In that article he says he achieved a 14" wide cut that way.
What are you gonna do when cutting a 4x8 into a 4'x4' or a city with similar large pieces on either side of the blade, overhanging all 4 edges of the table saw halfway through the cut,
like we've been talking about? Hold the miter guide against the plywood 4 feet away from your body as you feed it through the saw and lean over the blade, then free-hand it after the guide falls off the back side?
If Bob Vila himself told me to do that, I'd call him an imbecile.
Low blade height is what's going to get your work piece shot out of your hands and probably jabbed into your stomach.
There's this thing called "kickback".. More likely to happen with crappy Menard's lumber full of knots.
Or OSB with metal inside it.
For some reason I was actually seeing SPARKS coming off my circular saw blade while cutting OSB. Quite often too.
You're not going to get sparks unless the blade is hitting metal or stone or something that should not be embedded into OSB.
It wasn't staples, wasn't the metal brackets on the saw horses (although I did hit that once

) and nothing on the saw itself was close enough to hit the blade.
