SonexAus – Hinge Drilling Here is a trick I picked up somewhere that makes drilling hinges very easy and there is no need to ever measure anything.
Get a steel rule, in my case I purchased a 40” from Super Cheap Autos. Drill 3/32” holes at every 1” mark a ¼” from the edge as per the picture below.
To drill the holes in a hinge just line the rule on the hinge in the correct position pushed up tight against the hinge loop, drill through the first hole and cleco to the benchtop. Drill and cleco the last hole to the benchtop. Now you can drill all the holes in between.
Move the rule down the hinge to the next position and repeat until competed.
