I currently own a Delta 36-655. Since new April 2004, it has had a little bit of blade wobble that I can clearly see when the blade starts up and shuts down. I'm sure it is there all the time when the blade is running, I just can't see it. Needless to say, I finally have gotten into my first substantial project, a blanket chest/deacon's bench, and am now having trouble making cross cuts with my mitre gage. The saw seems to rip fine. I have squared the mitre gage to the blade numerous times, checked the blade squareness to the table numerous times, and can't seem to get it to cut perfectly true and square when crosscutting. Last night I got fed up with it. I finally removed the belt from the arbor assembly and removed the blade and with my naked eye, I can clearly see that the flange attached to the arbor shaft is not perfectly round and has a bit of an egg shape to it. When I attach the blade as normal and spin it freely without the belt attached, like I said before, I can see a constant warp in the way the blade spins. Would this be enough to cause cross cuts to not cut properly, but not have any trouble with ripping (although I do get very slight saw marks with a Freud glueline rip blade). I've been through two table saw books about squaring your saw, and I've also spoken to Dave Wooland (the table saw wizard who does table saw seminars at wood shows}, and he also told me that I have to get the arbor replaced. I also spoke to a warranty service guy who is coming out to my house on Thursday to look at my saw and I'm sure that my arbor will be replaced through warranty (it had better be!).
Has anyone else experienced something similar?
