I found this website tonight and thought it was worth sharing.

Good find Mark.  I made almost the exact same thing out of scrap aluminum a couple years ago.  You can fab one up yourself pretty easy since you can cut the aluminum on a table saw and drill the holes with your drill press.  Those dial indicators are cheap on Ebay or at Grizzly.com

Yes that is an excellent find, and I will probably have to get one of the cheaper versions.  However, it looks like I will need 2 of them to get it aligned for front to back teeth.  Man, they have a lot of attachments that you can add to the basic systems that really run up the cost though.

For those of us with Delta saws that require pounding the trunions back and forth, the PALS system worked well for me. (http://www.in-lineindustries.com/saw_pals.html ) I didn't buy it, but it was easy to build from scratch. It cut the foul language down by a significant amount.

I got one of these things, the "TS Aligner Jr Lite" version, and I like it.  I have a fold up, roll around, contractor-like knockoff table saw, which has been a challenge getting dialed in for good cuts.  Among other things, the tool lets you measure changes in the angle of the blade at two points vertically an inch apart.  If you're trying to make 1" square sticks you can make a cut, use a square and feeler gauges to measure how many thousandths you are off, then use the tool to adjust the angle exactly that much.  With my saw this is something that has always been "fiddly", requiring a lot of trial and error.  When my second cut was perfect I just about fell over from astonishment!

I know this is an ancient thread, but wanted to add a bit.

As Eric can attest, I've been fighting alignment issues since day one. Things just never cut right. I've added a Forrest dampener, PALS alignment, shimmed the living %#$ out of my fence, and things were still sloppy.

And now I figured out why.

When everything seems perfectly aligned and nothing works right, something is wrong in the equation. For a saw, everything is based upon one reference point - the miter slot. Usually guaranteed straight, mine turned out to be a boomerang of fail. Maybe the previous owner sanded or ground or wore it out somehow, but blade and fence alignment for the left slot versus the right were night and day. Now on the right slot there's only a few inches of shimming tape for the fence and it cuts like a champ. The other downside is that I need to get this one out the door asap before my upgrade comes (but that's for another gloat thread). To top that off, I'll get to re-align my crosscut sled and every other jig I have.

So my point is, trust but verify. A TS-Aligner is great, but don't base your readings off of one alignment point if possible.

Isn' there a two main bolts that hold the blade assembly in place on most table saws.  If yours has them, then it might be best to realign the blade with the miter rather than redo all of your equipment.
