Just thought I'd add my 2 cents worth.
I've used Forrest blades for years until they started loosing teeth..both the WWI and WWII lost carbides. They'd been sharpened many times so maybe they just wore out. I don't know where the pieces went, but I don't think my polycarbonate safety glasses would have stopped them. I sent them back to Forrest, thinking they would replace them, but Forrest just brazed new carbides back on. The weld was so poor I won't use them anymore. I still think the Forrest 80 tooth Duraline HiAT is the best I've found for plywood.
My radial arm is sort of built into my wall wood storage rack, so only gets used for rough right angle cuts, but I've found the Freud teflon negative hook angle cross-cut blade doesn't "ride up" on thick boards.
The Tenryu Gold Medal 40 tooth thin kerf was my favorite until I warped it. By the way if you're using thin kerf blades and use a stabilizer, make sure you use one on both sides. Forrest doesn't tell you this but guess what happens when you sandwich a thin blade between a 4 or 6" disc and a 2" collar flange...and the blade get's hot? Some sharpeners have a sort of high pressure roller machine that will flatten the blade body again, but if your cross-cuts are suddenly getting more chip out at the back then they used to, don't assume it's just not sharp anymore. You can easily get 20 mils of run-out on a warped blade. You can check it by holding a good straight edge against the body and point up at a light. My Forrest blades used to make glass smooth cuts but not anymore.
The latest WWSupply catalog shows a Delta arbor nut/flange assembly, with a machined flange the same diameter as the saw arbor (their number 36-660), for $36. Looks like a good idea for stabilizing, and it fits most saws.
My favorite cut-off is now the new Ridge Carbide Superblade..thin kerf, with virtually no chip-out. Ridge isn't well known but take a look at the awards they show on their web-site.
My favorite rip is the Freud teflon 24 tooth anti-kick back blade..I forget the number.
My Forrest dado set used to be good, but no one can seem to get them back to their original flat bottom cuts. I just got the new Amana dado set, and it's terrific...flat bottoms and little chip out. :-D
Blab,blab,blab...'nuff said.
