I recently helped a fired do a project, and because no good deed goes unpunished, I nipped the head of a brad nail with my WWII ( despite my friend's claim that the wood was clean.) I inspected the blade and the carbide looked fine, but it was dull. I couldn't even cut a pine 2x4.
I usually send my blades to Forrest, but the last time I sent it in, it took over 1.5 months to get it back. I heard good things about a local cnc sharpening place, so I decided to send it to them. I asked them to inspect the blad. They called and said there was no damage, so I had them resharpen it. I had the blade back in less than a week.
I did a test rip cut with some 6/4 maple. The results were terrible.

I did the same cut with my $20 back up blade ( also full kerf 40T) and the results were much better.

I called the company and they said they would "make it right." I just recieved it back today with a note saying that they inspected the blade, found nothing wrong with it, and resharpened it again just in case. They also said they made some test cuts and it worked fine. They send me a 2"x3/4" piece of oak they cross-cust as proof. I did another test with the same piece of maple. The quality is better, but not near as good as what I've grown to expect from the WWII.
I plan on contacting the company again later this week, but I'm wondering if any of you may have any insight on what may be causing this issue. I checked the alignment of my fence and it was right. I also checked how true the blade was when moved by hand on the arbor. It was 0.0045" out of true. Could this be the issue? What is a reasonable number? I checked my other blade and it was 0.003"
