Blade isn't cutting well. It smokes and the wood rides up as it is cutting. The saw is 14 yrs old but blade has only been used a few times. I think it needs alignment. Can I do that myself?

You should be able to adjust the fence but every model is different so I probably cannot tell you exactly how. My Biesemeyer fence has 2 set screws on front guide of the fence for parallel adjustment to the blade (this fence is a single piece fence). I had a Sears contractor saw that had 2 bolts on the top of the fence that needed to be loosened, the fence moved parallel, and the bolts tightened again (the Sears fence was a bolt together fence). Whatever fence you have I would think the adjustment would be on the front part of the fence. I would remove the fence (the fence only, not the guides) from your table saw and take a close look at it for any adjustment screws (the Biesemeyer set screws are somewhat hidden) . If the fence bolts together you will probably need to loosen the bolts to do the alignment. There is a quick check you can make to verify the problem is the fence not being parallel to the blade because your problem could also be caused by a bent saw blade arbor (the saw blade would wobble as it turns)

ø Lock your fence down and measure from the front of the blade to the fence and from the back of the blade to the fence. These measurements should be within 1/32” (ideally is should be zero).
ø If the fence passes the test above, you can see if your saw blade shaft is bent by sliding the fence very near the blade, locking the fence down, and rotation the blade by hand (unplug the saw first). If the blade rubs on the fence as it rotates then you could have a bent arbor, a bad arbor bearing, or a bent blade.
