Precision Aluminum T-Square

How to make Precision T-square

     To make their precision T-squares, Woodpeckers precisely machines an aluminum blade and secures it to a solid billet handle with six precision socket screws.  They drill 1mm holes every 1/16″ on the blade plus extra holes every 1″ for marking shelf pins.  They laser-engrave markings spaced every 1/32″ that are accurate to .001″, and they angle the outer edges of the blade 30 degrees to make the markings easier to read.  They do all this in their US shop.
Woodpeckers’ 12″ T-square will run you $80, the 24″ T-square will run you $110, and the new 32″ T-square will run you $140.  At least they throw in a fitted wooden storage case for the price.
