Building A Centering Jig

Building a centering jig  is a very interesting project as a shop jig. The purpose of this centering jip is to do exactly what it says. It will quickly and easily find the center line of a board right on dead center.

I’m sure from time to time you have had the chore of trying to find the dead center of a board whether it is the center of the edge or on the face, and found that it was time consuming and not always easy.

Building a centering  jig is constructed primarily from scraps that you will have around the shop.It will require 3/4″ material about 1 1/2″ wide by 6″ long. A couple dowels 1/4″ or 5/16″ you may have kicking around the shop and a regular lead pencil.

  • You first take your 3/4″ stock and cut it to size. 1 1/2″wide by 6″ long
  • You may want to round the ends and run it past the router to soften the edges giving it a professional look.
  • Very carefully draw a line dead center of the stock from end to end.
  • About 1″ in from each end, mark the location and then half way between these two points, make a center mark.
  • Take your center punch and mark all three holes at the locations marked.
  • Depending on the size of your dowels used, drill the two end holes on your drill press for accuracy.
  • Drill the center hole to fit your pencil making sure it fits snugly into the hole.
  • Drive your two dowels into the bottom side of your jig and insert the pencil on the opposite side so the lead stick out a bit.

How To Use The Centering Jig

If you require marking wide boards, simple make a jig the same way but longer ( maybe 16″ instead of 6″ )
