Several readers have asked how to go about squaring up the two legs of the English Layout Square from the December 2010 issue of Popular Woodworking Magazine.
Do you square it up before assembly? After? What tools do you use to make it square? How do I determine if the square is indeed square? Why isn’t evaporated milk a gas?
I made this short video this morning that shows how I do it. It takes about five minutes. Here are the tools:
1. A jack plane with a 90° fence — because I’m a filthy cheater.
2. A small try square.
3. A piece of posterboard with one straight edge.
4. A sharp pencil.
5. An accurate straightedge.
Hope it helps.
