I have a well used Delta 34-440 contractor's saw; it has probably cut over a million bf of lumber. The original owner was a professional house builder. I am the second owner and have used it hard for the last 5 years as well. The bearings are the original. The blade wobbles +\-5/1000". I assume this is why I get some rip cut scoring even with an expensive blade. Should I change them? If so where do I get them? My dad owns a farm, so I can get help from him in changing the bearings and use his tools.
Thanks
