My table saw is tapering cuts. It I cut something say 2 feet long it will be about 1/32 thinner at the end of the cut. Is this an alignment issue?

make sure the arbor nut is flat and your fence is parallel to the blade

I don’t know why but I am really bad at trying to figure out how to align the fence.

What kind of fence do you have? A bad one might be pushed out of parallel at the end of cut.

the wood whisperer has a good video from a few years ago (i think) that goes over how to calibrate a table saw. Also, if you can find it, norm did a quick alignment check in the table saw special of the new yankee workshop. essentially the idea is to first get the front and back of your saw blade perfectly aligned with the miter slot, once that’s done, check the front and back of your fence against the same miter slot to make sure it’s in exact parellel with it.

One other thing, I had bad bearings on my saw some years back, and nothing came out straight or square despite hours of tuning, the vibration just moved things around too much, once i replaced those, everything was perfect. So if your saw is vibrating a lot or sounds like marbles rolling around in a coffee can, it might be worth checking into.

These are the wood whisperer videos

I saw your Subject line and thought—Cool, he didn’t even have to build a jig.

+1 for aligning the blade to the table, the table to the fence, etc.
Sometimes the splitter is out of alignment and it pulls my material to one side…

with birdsmyer fence
That could be the problem. Did you by any chance buy this fence from the same guy who sold you the Roleks watch, the guchi purse and the Nyke sneakers? :)

It sounds like some alignment is off a bit.

First align the blade to the miter slot; then align the fence to the miter slot. To align the blade, all you need is a combination square. Set the head of the square against the side, closest to the blade of the miter slot. Slide the square blade so it touches a tooth on the saw blade at the front of the blade. mark that tooth with a magic marker. move the square to the rear of the blade and rotate the saw blade so the same tooth touches the end of the square. If they don’t line up, you will have to loosen the bolts that holds the top to the cabinet and adjust until the blade to slot are the same.
To align the fence, use the same combination square and test it at the front of the fence and at the end of the fence. Adjustments can be made by turning over the fence and adjusting the two set screws. I don’t have a unisaw, but someone else here can walk you through the alignment steps.

CAUTION: Make sure the saw is unplugged before doing anything.
