So this is what I am trying to duplicate. This is the wooden door jamb post for the rear door.
I started out with a flat sheet 4 foot long by 4 inches wide.
I want the face of the new steel jamb to be 1 3/4" wide so I bent the sheet in the break.Here I am using the stretcher to put a curve in the lower half of the post to duplicate the original wood one.
This is the finished product after shaping and trimming
I also made the opposite side as well
This is the new steel post installed along with the sub-rail extension I made earlier. Today I will work on the other side and hopefully tie them together at the top and bottom.
