I did go slow.
But I just looked at the blade on the circular saw. It's a fine tooth blade but says "OSB and plastic" on it. Turns out I'd taken the finishing blade off and forgot.
I got that blade for cutting the plexiglass for that skylight thing. It did a good job on the plexiglass, BTW but totally sucked on the OSB. Dogs the motor and makes a burnt edge like it's dull.
As for why I didn't use the table saw on the 40-1/4" line it's because it wouldn't fit.
To make a good square cut on a table saw you need to have the work piece between the guide and the blade, with the scrap being removed.
You're removing the scrap from the work piece, not removing the work piece from the scrap.
The reason is when the work piece is hanging 40 inches past the blade, it's hard to feed it straight.

I've always remembered that because it was odd hearing a teacher use a double negative. Mr Manak. He was one of those human encyclopedia types like Hammer166. Except he chopped off the tip of my finger in a door jamb and then transferred to the high school the same year I did so he could make fun of me for 5 years instead of one.
So a few years later, out of curiosity, I put a little scrap of plywood in the planer at home thinking it's just going to delaminate it. No, it shot the whole piece of plywood out at 800 mph.![]()








.....those stands SUPPORT the wood, making it SO MUCH EASIER to feed the work.....
