UPDATE my customer watched the video and read some of the comments and got a little freaked out. They decided to scrap the coupler, but still paid me for the work. I had my NDT(Non Destructive Test) vendor come and check it out. It passed with flying colors! Infact the weld looked better than the surrounding material, excellent fusion of base materials. My weld inspector watched the video and called to confirm my process. To say the least, he was happy. But it will go to scrap, even though it is stamped "Repaired, Not For Interchange". Better to be safe than sorry! UPDATE

This repair of a locomotive coupler is totally illegal for service. But since this is for a nonrunning locomotive in a static display in a park, I will be fine.

I get many interesting repair jobs, and this one is something I have never done before. I have repaired heavy castings in the past, but never a coupler. See my process of making sure it holds together, and how I hide the repair.

Heavy repairs come in all forms. When equipment breaks, sometimes the repair is quick and dirty. In this case, it was all cosmetic. But why do just a cosmetic repair when it can also be functional.

I hope you enjoy this repair and the process I have developed to ensure a 100% success rate on these large jobs.
