Good point: as this discussion is unfoldng, I'd like to mention that
among other saws I use daily, there are two Tannewicz with 40" wheels
and we never use anything bigger than 5/8" blades, carbides or not, and
they are fine for re-sawing as long as the guide bearing is close to the
work, blade is sharp and un-kinked, and you don't turn it too hard.
