Tough, it would be a lot easier to try to answer your questions in a helpful manor, if you were to give more facts. Like in your last posting, you stated that you think that it is now with the different lumber your using. That's great if that's all it is, but, you never happened to mention what type of wood you were using in any of your postings. And, I don't see where you let us know what type, or, brand of blade you were using. I do know the question was asked a couple of times, but never answered. Now, don't take this the wrong way, I'm not complaining, I'm just trying to point out, that you should list as much info as possible when an issue comes up. So that we can give you, the proper information back.
