JIGS & ACCESSORIES These supports do a couple of # things. First, they slide in and out yof the base so you can adjust the angle of the table. Second, they prevent the pressure of the feed rollers from deflecting the table when making a cut. dadoes. To adjust the angle of the table, each support is attached to a runner that slides in a dado in the base, see Fig. 1. The idea is to locate the inside shoulder of these dadoes so the table supports end up V4" outside the housing of the planer, see detail in Fig. 1. This way, the supports won't bump into the planer as you slide them in and out. runners. Now the two winners (C) can be cut to fit the dadoes, see Fig. 2. These are pieces of V4" hardboard with an adjustment slot cut in each one. Note: Attaching strips of sandpaper to the bottom of the runners will keep them from slipping when they're tightened down. a supports. With the runners ^^ complete, I added the wedge-shaped table supports (D), see Fig. 2. The exact angle of the supports isn't critical. But it should be the same on both pieces. So I carpet-taped two 'V-thick hardwood blocks together and used a bandsaw to cut them both at the same time. While I was at it, I knocked off the top corner. After drilling a counterbore in this corner to use as a finger pull, the supports are simply glued and screwed to the runners. At this point, it's just a matter of adding a machine screw and wing nut to tighten the runner against the base, see Fig. 3. To prevent the screw from spinning, the head is epoxied into a countersunk shank hole drilled in the base, see Fig. 3a. filler strips. Finally, to provide a continuous surface for a • hinge (added later), I cut two filler strips (E) to fit the openings at the end of the dadoes. They're simply glued in place.
