Yesterday I needed a carpenters square to lay out a large piece on some plywood. My old Empire square gave up the ghost about a year ago after being bent when something heavy, (My Boot with foot installed), landed on it.
I went down to my trusty local True Value Hardware store to get a decent square.
About the only choces they had were an Empire Drywall square, (Those aren’t even close to square), Empire Speed Squares and Steel 16X24” Johnsons Carpenters squares.
I compared several of the carpenters squares and picked out several that seemed to be close to square then wandered around the store looking for a true square edge I could use the ‘Flip’ method to check them with.
It’s actually pretty difficult finding a clear space to do this in a store, but I found a spot to test.
3 of the squares were off a little bit, but one seemed pretty close and that’s the one I bought.
This morning I checked it against the square edges of my benches and it was 5/16” out of square at 12” and a full 11/16” out at 24” using the flip method.
I next got my engineers square out and checked it… using the flip method, it was exactly correct at 12” and at 16” at the same points on the benches.
Even though the Johnsons square is ‘just’ a carpenters square and not really meant for exacting standards, If I tried to lay out a set of drawers or door panels with this thing they would have ended up so far off they would have been completely worthless except as scrap. I wouldn’t even try to lay out a roof or building with this POS.
