Vern's Stories : I did not know this.
Dad showed me that 60 some years ago except he used the rounded end of a small ball peen hammer instead of a center punch and tapped it with a bit larger hammer. I still have his good square and the one he straightened. The good one is at least 3/32" thick and built a lot of buildings here on the farm and I've used it in my welding shop for the thirty three years since he died.
Tapping it on the outer corner forces the metal to "close the gap" - it twists the level arms closed. Same for the inside of the corner, it forces the two sides open. Took me a minute to figure that out!! All of my squares are NOT aluminum, they can warp if they are dropped on an unyielding surface such as concrete. More so than a good steel square, anyway!
That was good!
ReplyDeleteI've been building stuff crooked for years why worry about it now?
ReplyDeletewas a carpenter for 37 years.never saw this one. a little dubious.
