Begin by ripping four halves for the runners (L) to width, see Fig. 11. Then rip a V^M-wide groove on one face of each, see Fig. 1 la. (This is for the threaded rod to run through.) Next, glue the halves together with the grooves facing each other, see Fig. 12.

Shop Note: To align the grooves, I used square plugs. Once the runners are clamped together, remove the plugs. But don't throw them away. (YouH use them later.)

tongue. The top of the workbench is screwed to a tongue on the top of each runner. To create this tongue, cut a rabbet on each face of the runner blank, see Fig. 13.

Now, cut each runner blank into two lengths, see Fig. 14. These pieces should match the widths of the two top sections.

front runners. The runners need a few modifications before assembly. To seat some nylon spacers at the front end (refer to Fig. 20), the short, front runners need a shallow hole drilled in them, see Fig. 14a.

Shop Note: To guide the centerpoint of the drill bit, use the same plugs that kept the runners aligned. Plug the holes and mark an "X" to indicate the centers.

SLIDING RUNNER. Now, the longer (back) runners need to be trimmed to slide easily in the guides. This is done by re-cutting the rabbets that created the tongues, see Fig. 13. Simply set the dado blade so the rabbet is Vi6M wider and V32" deeper.
