“just for two pieces of metal stamped together at a 90° angle.” Interesting description.

Starrett is to squares what Festool is to routers and dust collection. Do you need Starrett quality? Most likely not for many applications. Depends on what your definition of “close enough” is. Start precise and the inevitable mistakes or sloppiness will be minimized. Start out out of square, and they will be multiplied exponentially.
You can have my Starretts when you pry them out of my cold dead hands. I thought that would be appropriate considering some of the off content posts lately. Always buy the best tools that you can afford and need to work at the top of your game and you may only buy that tool once.Whatever square that you decide to use Emma, good luck and have fun with the greatest hobby on earth.
