ABSTRACT:
An assembly jig including a flexible binder that encircles an assembly of frame members having mitered ends, the binder being attached to a draw bar guided along a guide section of a main support. The support is attached to an angle member against which two of the frame members meet to form a corner of the frame, and the guide section is in the same plane as the frame and extends at an obtuse angle away from each of the two frame members that form the corner. A threaded rod journaled in the main support engages a matching threaded opening in the draw bar to pull the draw bar along the guide section as the rod is turned, thereby exerting tension on the binder to draw all of the mitered frame members into proper alignment and to hold them in that position under pressure while they are being permanently joined to one another by glue or other suitable means.
