Not so much EMT, but with PVC here, I can look at what's needed for a certain bend or off-set, even multiples, and bend it right there and then.
It's something I suppose that you pick up with experience.
I haven't had a bend that hasn't fitted yet.
Just as a small question, do you guys put a spring-like thing inside the EMT before you bend it to prevent from kinking it?.
We do with PVC, without a spring, it's the quickest way to make a PVC Boomerang!. [Linked Image]
