1" diameter thru Thru hole slightly larger than head of base bolts Hole and counterbore for handle bolt, washer and nut Countersunk hole to match router base Mounting plate 1/4" Variable acrylic sheet Variable Bottom view all, you don't want metal hardware dragging over the surface you're trying not to cut. Using the Jig Mount a straight bit in the router. I commonly use a 3/4"-diameter bit, but any bit smaller than the plate opening will do. Adjust the depth of cut to the level you want to rout. If you want to trim one surface flush to another, raise or lower the bit until the tip barely touches the surface on which the base rests. If you want to cut slightly above a surface, as I did, simply raise the bit to the proper height. I used a piece of paper as a feeler gauge to position the tip of the bit about .003" above the surface - close enough to look flush, but far enough away to make sure it wouldn't cut the laminate on which the jig rested. Then make a test cut to check your setup. As you cut, pay close attention to the direction of rotation and the direction you move the trimmer. I cut with the router so the bit rotation pulled the router through #8 x 1/2" round head wood screw Exploded view the wood trim and away from the laminate surface I was trying to protect. If you have to "back-feed" (where you move the router so the bit pulls in a direction you don't want to go), move the router very slowly and keep the base pressed firmly against the guiding surface. For delicate work, cut the wood in several passes, lowering the router a tiny fraction of an inch between each pass. PW You can use a piece of paper to position the bit about .003" above the surface.This This jig also will trim wooden plugs flush with the surrounding surface without will look flush but still ensure you don't hurt the surrounding laminate. cutting or marring that surface. popwood.com 35 |
