Since after brazing frame alignment is somewhat dependent on how much heat is applied where and that many jigs don't allow for unrestricted access to all parts of the joints it's easier to braze a joint in the jig with unevenly applied heat then with the frame out of the jig (after pinning or tacking to hold the design alignment).
I also build with the jig tack, align on a surface plate then finish brazing out of the jig. Andy.
