The decision to fab a squareness comparator came about whilst trying to check if the jaws on my milling vice were square (they were not).
I rigged up a mag base with a dial indicator attached and a bit of linear rod stuck to the magnetic base as a work around, but knew I needed something a little better and a little more accurate.
So after hours of scrolling the interwebs I found a design that was perfect for what I wanted to use it for and I set out to make it.
This is what I came up with...
-Base is cast iron
-Knobs are brass that have been blued
-Pivoting arm, dial clamp and front bumper insert are 4140 hardened and tempered
-The rest is hardened stainless steel
