Adjustable Table Saw Dial Indicator Gauge for Checking and Setting The Accuracy of Table Saw, Necessary Tools for Table Saw Alignment and Calibration

It is a quality instrument.

I bought a new table saw and wanted to make sure the alignment of the blade to the fence was accurate.The tool worked perfectly, but I never used it again, as I found the fence was very accurate, as was the blade once I locked it it.If your using it to align, table saw blades, rip saws, band saws, alot, it's great, but if it's a one-off deal, a T-square will work just as well.

The included indicator is the biggest pile of crap I’ve ever used. I’m a machinist and have used dozens of indicators over the years and this one just straight up sucks. The rest of this product is decent but it’s not as good as the a-line it product.

I used it to adjust my blade and fence and it worked. Getting them down to .001 felt quite satisfying.It's not great, not a pleasure to use, but it works. It's fine. Especially for the money.-1 star for a missing miter screw and the other screw not being a trust screw (as some pics show)-1 star for being fiddly (probably because of the missing screw).There are no instructions but it's easy to figure out after looking at the pics on Amazon. There is a VERY shallow slot to square the two pieces, but it's so shallow that I wasn't confident about it being square. Of course, that doesn't matter for checking a distance in 2D.Thrust screws on the miter channel arm would make this infinitely better and less fiddly. Pics show them, but the screw in the box did not have a spring loaded bearing.If I had the money and justification I'd buy the Woodpecker 2.0 because it self centers and has long range. Not sure about other self centering gauges, the one with the ball bearings is problematic because it would be easy to loose a bearing.

Can't get it tight in miter slot, the dial indicator is rough & jerky & won't read the same twice in a row.
