How to safely and quickly make custom molding if you have a router, but don't have a router table

Bill Young from Berkeley, CA writes:

I needed a special molding to complete a baseboard detail, but my router table was several hundred miles away on another job. Fortunately, the situation forced me to come up with an alternative method for site-milling trim  stock. I think my new method is faster, more accurate and safer than using a router table -- especially if the moldings are narrow and thin.

As shown in the drawing, I used a scrap of 2x stock about 1 ft. long and about the width of my router's base. I cut a lengthwise  groove near the middle of the 2x, just a pinch larger than the depth and width of my molding stock. Then I used a hole saw to bore a 1-1/2-in.-dia. hole that is offset from the center of the groove. This hole accommodates the router bit, and it should be to the left of the groove as you face the jig. This is to ensure that the router bit, which turns clockwise, will be turning into the work as you feed the stock into it. Next, I bored a similar hole in the top of my job-site workbench to allow the wood chips an escape route.

I positioned my router over the hole in the jig and anchored the router to the table with a pair of clamps. The clamps were arranged on opposite sides of the router's base, in line with the groove in the 2x stock. By sighting down the groove I could easily adjust the router, both vertically and horizontally, until I had the bit in the exact position that I needed for the molding profile. Cutting the moldings is a simple matter of turning on the router and feeding the stock into the groove. In a few minutes I had hundreds of feet of molding. And because the stock was captured in the groove of the jig under the base of the router, my fingers never got near the cutters.
