Router plate with follower guide
Router base plate and a template guide. For an older Black and Decker model 7914 router.
I was making the parts to build 75 cubbies/lockers for my son's school (be careful when you volunteer) and I needed to router 600 dadoes for shelves. So anyway, I broke the router base plate (again) by dropping a tool and hitting the plate. Well, that's what I get for buying (and abusing) a router with a cheap plastic base plate; it has broken twice in less then 30 years!
The template guide is 1" in diameter and is glued through the 1" hole in the base plate with ABS glue. It will then fit and slide in the 1" slot of the shelf template to make the dadoes.
Of course the base plate can be used without the template guide,
Note: Plate is 6" (152.4mm) in diameter
Screw holes are 2 1/2" (63.5mm) from center and 4 1/4" (108mm) from hole to hole
