OK, my app has nothing to do with doors or frame installation, but rather
mounting something (a chinup type bar) TO a door frame.

Here is how I would install a chin up bar in a steel door frame.

Weld plates to the end of the bar so the over all length is the same as the
space between the frame.

The plates need only be as wide as the door stop section of the frame.

The plates should have 4 1/8 inch holes in each.

Position the bar, drill one hole on one side and pop rivet.

Level the bar and drill one hole in the other side, rivet.

Drill three more holes in each side and rivet.

The project is now done. With 8 rivets in sheer it will not go anywhere.
