I lurk here often and pick up lots of valuable information so first off, thanks to all of you. Here is my current problem. I have a TS3650 that I have had for several years and had no problems. As of late all my cuts were chattering and burning. I figured the blade was getting dull. I just got a brand new WWII blade and put it on and got the same result. I went ahead and did a full tune-up. Cleaned and lubed everything, removed and realigned the fence, it was out, adjusted to blade parallel to miter slot, both fence and blade are accurate to about .002 now. After all this, no more burning and it feels better but, wood still chatters and bounces when trying to cut resulting in a rough cut. I checked that there was no play or movement in the arbor bearings and that it is running true. Now I'm stumped. I don't know what else to check or adjust. Any thoughts? Any help or suggestion would be appreciated. And, just for the record, the saw used to cut 1 inch oak like butter in the past so all I do know is something changed. Thanks again.
