Guide Units

A pair of guides sandwich each runner, allowing the runners to "telescope" in and out. After cutting four halves for the guides (M) to size, rip a groove down the length of each piece, see Fig. 15. The depth of this groove

3 plug guide bit should match the depth of the original rabbets in the runner blanks spacers. Unlike the runners, the guide halves aren't glued together — spacer (N) holds them apart. This way, the back runner can slide in the guide unit, see Fig. 16a.

Cut each spacer blank to match the length of the guides and the width of the runners, see Fig. 16. Then to determine the thickness

When the spacers fit between the runners and the guides, screw the guides and spacers together, see Fig. 17.
