About

We built these as there wasn’t square on the market that was universal to different vise sizes or allowed you to change indicators easily or use your own. Currently in the market you find 5″ and 3″ off center but not a tool which can do both or even a wider range. Also the magnet used for zero’ing the square was kept separate. In this case it is held under the main spindle shaft for easy keeping. A nylon washer protects it from chipping.

The spindle square is adjustable with 3/8 holes for 3-6″. It can be used to tram on multiple vise sizes, and machines such as your mill, drill press, sine bar and lathe. You can use any indicator with a 3/8 stem so you can install a brand or resolution of your preference. The hardware will never rust and shouldn’t damage your indicator unless you over-torque the thumbscrew.
