I've had a forest WWII on my Ryobi bt3000 for a few years now, cuts
like glass. When I bought the blade at a WW show, the gentleman from
forest asked the type of saw and sold me a thin kerf blade, based on
my machines' horsepower I'm sure. Also sold me a stabilizer, he said
because it smooths out the thin kerf blade. I have cut both with and
without the stabilizer with no percieved difference in cut, noise,
etc. The cut is only marginally better than the stock Ryobi blade that
came with the saw.
What amazes me is that, one day with little else to do, I measured the
arbor runout on that saw (off the edge of the blade I had verified was
FLAT) and found over .005 runout, but I STILL get glasslike cuts, both
cross and rip.
I agonized for days over buying a new saw to remedy the situation,
then finally realized it's the CUT, stoopid. Kicked myself and went
back to work.
