frame corners (see photo). We've scribed lines on ihe jig base to index the swivel work support at the most common angles (15, 30 and 45 degrees), but you can scribe index lines at just about any angle that you regularly use. Adjustability: With most home-made jigs and fixtures, the accuracy of the jig is only as perfect as the jig maker was with his construction and assembly. If the assembly isn't quite square to the saw table, or if it doesn't fit snugly over the rip fence, then whatever work is done with the jig will be imperfect by that amount of error. In fact, in order to do perfect work with a home-made lenon jig, your jig would need to be made just about flawlessly. Unless, of course, there was a way to fine-tune the jig on the saw table. Our Super Jig incorporates exactly this adjustability. Using a simple machine screw/T-nut/rub strip alignment system, our jig can be precisely adjusted both for a snug fit over the rip fence, and to an exact right-angle setting with respeci to the saw table. And. in addition to these adjustments, there's also a screw for "zeroing" the swivel worit support at precisely 90-degrees. Before You Cut As you can see from the photos and illustrations, the jig basically consists of the base (A), to which is screwed a pair of brackets (B), the base support (C) and the adjuster block (H). A fence guide (D) and connector (E) are screwed to the brackets, and the rub strips (J) are in turn mounted to these parts. The swivel work support (F) and its stiffener <G> are mounted to the base with a pair of machine screws and knobs, and Ihe hardwood edging (1)—applied to those edges of the jig where wear is most likely—completes the wooden parts for this project. You could go to work and build the jig exactly as illustrated, but we don't recommend it. We built the jig to fit a particular saw, and obviously, ail table saws aren't the same size, nor do they have the same size fence. In building your jig you'll need to size the notch in the brackets, and the widths of the base support and fence guide, based on the actual size of your rip fence.
