Cleo:
My table saw prefers the Oshlun (or a clone) with two chipper teeth on each chipper. It chokes on better blades, not enough power. Probably need to save up my pennies and get a better motor and direct wire it, too much power drop with a cord, even a good one.
Harley:
I change blades all the time on my saw, I use a rip blade for rips, a combination blade for rips in thin material or plywood, and a good crosscut blade for crosscuts, especially in hardwood. I also cut a wide variety of dados for various purposes, changing blades on a table saw is just part of using one.
When I'm making boxes, I tend to collect up wood, cut all the sides to length and width, then set up the box jointjig, get everything aligned perfectly, and cut half a dozen boxes or more at one time. All the boxes use the same jig, just more passes for the deeper boxes. That way, once I get it right, all the boxes work out properly. I've got mine set now so that I have to tap the boxes together so there are no spaces between the fingers at all. Just a tiny bit of glue and they are completely sealed. Once they are assembled, I coat them with a generous coat of boiled linseed oil, then alkyd primer, then two or more coats latex exterior paint.
