Q:

In FWW #175, Jeff Miller made it look easy to install bed-rail brackets. I want to know how he gets such clean mortises in the end of 80-in.-long rails. Does he use a router or cut them by hand with a chisel?

A:

There are a couple of tricks that help you use a router to cut mortises in the end of a long workpiece. First, use a jig to support the router. I built the T-shaped jig shown here. The top of the T supports the router, and the base clamps to the workpiece. Second, hold the workpiece at an angle in the workbench vise. I’ve found that angling the long rail this way is safe and comfortable, although it takes a little work to support the router. Scribe the exact outline of the bed-rail bracket you want to use. Once you’ve finished hollowing most of the mortise with the router, clean it up with a chisel. With most of the wood already removed, the chisel should track the scribed lines cleanly.

 

Simple Jig for Mortising. The long base on this jig (drawing) helps to steady it on a long rail (top photo). Size the base to match the width of the rails you’re using. Cut the mortise in the top larger than the bed-rail bracket (photo at right) to allow for use of a guide bushing on the router. Be sure the mortise is centered on the end of the rail (bottom left photo).
