Charles, you can eliminate the first two fairly easily. If you bought this as a new blade then Forrest will re-sharpen it without any problem.

Beats me? I didn't know that you could send blades back to the company for sharpening. Is it just Forest or will other companies do it as well?

Charles, I would check my table for square if you have any doubt at all and check the perpendicular on your fence too. I notice that my blades get a resin build up but have never cleaned one. I think I'd follow Matts advice first. It sounds like a simple process and might save you a buck.

I recently bought a new WWII to replace the standard blade that came with my TS. This is my second WWII, it also burns the wood and the wood is very hard to push through and leaves a wavy cut line! I removed it and replaced it with the original blade and I am cutting again. I am going to contact Forrest, I have not used the blade enough to get pitch buildup or to dull the blade. I think the blade is defective.

I have both the WWII's in the thin and regular kurfs. I haven't had a problem with either one of them. I have a 5 hp. X5 UniSaw, and these blades cuts like slicing butter.
Bww, and Sam: Sounds like if you're getting burning on the wood, you need to clean the blades to remove the pitch and gum like Matt said. Build-up of this junk will certainly make the blade dull and it has to work harder to cut the stock, especially hardwoods. I don't know what kind of saws you have, but some under-powered saws will bog down. As long as allignment is good, they should work fine. Sounds more like a dull blade to me. Simple Green, 409, or a cheap oven cleaner will do the trick. If the blade is defective, send it back to Forrest and get a replacement. They have a good guarentee on them. Just my dime(inflation).

I am paranoid about the brazing for the carbide. I use the blade & bit cleaner from Rockler, in a little clear plastic planter saucer, okay I guess it's not so little… Let it soak for 30 min or so, use an old toothbrush to scrub heavy buildup off, rinse / dry the blade, then with a coffee filter and funnel, filter the cleaner back into the bottle. Works well for me, and not terribly expensive. Actually come to think of it, my OEM blade needs cleaning, as does my Diablo 40T…

Not familiar with your specific fence, but burning issues I have had have been due to maladjusted fence, lucky I didn't have kickback…

If your blade is dull, sharpening is a pain, but rumor has it that Forrest will sharpen it for you…

hey dbhost: I have that same cleaning kit from Rockler, with the tub and cleaning solution. Works real good.

I haven't thought of the coffee filter and recycle trick. Thanks. I'm gonna try it.

I have 2 Forrest WW I's so I always have one to use while the other may be out for sharpening. The one I was using started to dog and burn so I thought it was dull and needed sharpening. Before I took it in I soaked it in 409 (my cleaning method of choice) to get the pitch off. Once clean I took it in for sharpening. When I got there we both took a close look at the blade and it didn't really look like it needed sharpening so I didn't get it sharpened. Took it back home, put it in the saw and it cut just fine. It was the pitch build up causing the problem.

Most premium 40T general purpose blades like the WWII, TS2000, Super General, and Fusion have very low side clearance angles which give wood that nice polished edge, but it can also make them a bit more prone to burning. In addition to needing good alignment, and clean blades, you might try raising the blade just a bit higher to see if it helps reduce burning.

"I use Goof off and a metal film canister to soak my saw blades in to clean the pitch off . Works great."

What a great idea Jim….I never thought of the film canister

I thought the film canister was a good idea too but was wondering if they're big enough for 12" blades? I bought a round inch and a half high Tupperware container 20 years ago from a friend of mine that sold the stuff. She had to ask me three times "you really want to buy this?". LOL Guess bachelors don't buy a lot of Tupperware…

Charles, another suggestion,m if cleaning and checking your table saw alignment does not help your situation, is to cut your lumber about a 1/16 longer than you need and then make a second pass to cut it to the exact length. This will help to eliminate the burning.
