Center Pin Cutting Jig

In AW (vol 24, no 2), John Giem wrote a very interesting article titled, “Transform Your Tape Measure.” I decided I would like to make something similar, but I thought preparing the pins was somewhat fiddly and potentially dangerous if done on a bandsaw. I have developed a simple jig, a minimiter box, to prepare the needed pins. The fixture is made from a length of ¾" (19mm) hardwood and a couple of pieces of ⅛" (3mm) birch plywood.





I keep .375" (10mm) dowel stock on hand for several projects so I decided to make my pins from .375" (10mm) stock rather than the .25" (6mm) dowel used in the article.





On one end of the hardwood, I drilled a .375" (10mm) hole, .125" (3mm) deep, which is the same depth hole made in the sides of the tape measure. I placed a stop at the end of the box and sawed a slot the correct length of the pin on the side of the box. I can simply cut the pin using a razor saw.

  

 
The pin is then pressed into the hole at the end of the fixture so that the pin is at the proper depth and will also be perpendicular to the fixture’s surface, which is important in the assembly of the tape measure. Using the razor saw, I cut the slot in the pin to the surface of the fixture. When the pin is fitted into the side of the tape measure, the slot will be flush with the side so that the tape will fit the new case properly.
