So ya know all those numbers on the sides of the framing square? Turns out they are really useful! I have a few other videos out there, and it is time to share with my friends at LJs. Enjoy!

The framing square is a much more amazing device than most people realize. A proper square has a lot of other formulas on it also. There is a free download here:

There are also a few other downloads on this site about the square. Happy reading.

Yeah, I love the thing. Great to use and teach with. Cool thing too, because it doesn’t need batteries!

When you do BF calculations, do you use the actual dimensions or the nominal dimensions? We all realize that a nominal 2”x4” is really 1-1/2”x3-1/2”, for instance. My guess would be to use actual, but I’m not sure.

Don … I would say use actual dimensions instead of nominal.
