This is an old 2003-era MM16, probably 1st generation (the included manual says 1st edition). I got it as a demo at a woodworking show in January 2004 and it was all set up, fully assembled, and running. It came with a Lenox Trimaster 1" blade. I brought it home, maybe tweaked a thing or two and it's been running well ever since.
Confession: I've never changed the blade (now going on 20 years). Also I keep the tension up high all the time. I did but a 1/2" Wood Slicer blade right away but its still hanging on the wall behind the bandsaw. I also never readjusted the guides after the initial setup as it seeed to be fine.
I typically use the saw for a few cuts once or twice a month - the last time I remember using it was about 2 months ago and it worked just great. I fired it up for a few small cuts yesterday and it sounded awful and is making really rough cuts. I checked and adjusted the guides (euro style) and thrust bearing but no noticeable change.
Here is a short video showing the sound that the saw is making running under no load.

And here is one showing the sound it's making while cutting.

Finally, here is a picture of the cut that is being produced. Prior to this, the cuts the saw produced were very smooth.

Not sure where to go from here. Should I bite the bullet and switch this blade out for the Wood Slicer as a test. As I said, I've never changed the blade on this saw before so it's a little daunting. On the other hand, I guess I should finally figure out how to do that. If it is the blade, I can't complain about the service it's given me.
Anything else I should look at?
Thanks, Mark
