Some of the more successful bolt-on mounting brackets wrap around the head tube a bit more and send the mounting bolts in from the side, so that the side stress on the bolts does not tend to loosen them so much. After messing around with several different options, I've decided that welding the bracket to the frame is the safest way to go.
Please keep posting photos. I'll try to dig up some more too.
