Blade Alignment Jig
This jig is very useful for aligning your table saw blade or jointer fence to 90 degrees. No more need for slapping a square against your blade and sighting for light or using feeler guages. This method is quick and very accurate. For a video of this jig in action please go here. (use scroll bar at right – last video on bottom)
First square the jig by pushing it against a good quality square and set the dial to zero.
To use the jig, push it against the blade to align it to 90 degrees. (Unplug your saw first).
The jig is simple to construct. It consists of two boards mated together which are off-set. Two screws are used to position the jig consistently against the surface being measured/adjusted.
