How To Check A Giant Machinist Square... OR at least how I did it!
Not having a huge amount of measuring tools I had to make do and come up with a way to check the squareness of this Old 39" Machinist Square. I find it hard to call this Brown and Sharp Square an Antique but it has been around for a while... Thanks For Watching ( me fumble around :)
