I finally gave up on the stock fence for my Craftsman 113 and ordered a Vega Pro 50 as a replacement (review forthcoming). The installation went smoothly, but Vega’s instructions for squaring the fence to the miter slot don’t inspire a lot of confidence. After a little bit of research, I decided to build a jig that would allow me to use a cheap Harbor Freight dial indicator to ensure accuracy.
Inspiration for the jig came from a photo jcwalleye posted a few years back. I modified the design to include an adjustable width miter bar that ensures the whole setup can be snugged down in any miter slot, not just the ones on this particular Craftsman. It should also prevent seasonal expansions and contractions from introducing slop. The whole thing is made out of a scrap of kiln-dried maple I got from my father, except for the knobs which are oak from a pallet stringer (how-to for the knobs forthcoming, maybe).
The jig works like a charm—I got the fence zeroed out, then added a 0.001” toe-out at the rear. It can also be used to align the blade, which I got dead-nuts after much fiddling with a hammer and scrap block of wood (table mounted trunnions, FTW). Furthermore, as you can see in the fourth picture, the jig can also be used to check a drill press table for perpendicular to the quill—it works only so-so with the factory table, but I think the results will be much more pleasing when I finally get around to building a table that’s more conducive to woodworking.
Finally, in case anyone else wants to build the jig, and doesn’t want to guess at dimensions and the like based on the photos, here’s a link to the SketchUp file I created.
