well I chisled some, filed some, locktite a lot. Did not work, they still moved after about 6 hrs dry time

It was really hard to get the 1/4" chisle in the peg end. The outside part was easy. I did get some good marking on it with rasied edges and at first it was nice and solid. but...... did not last long. One last try, I will drill through both connecting ends and either pin or allen set screw it. If that doesnt work, weld and really mess the thing up
