I have seen several sockets that fellows have made and none were alike. One was a piece of round stock that had a hole bored in the center the size of the outside diameter of the nut and then a piece of round stock that had been turned to fit that diameter and sliced to fit the flat on the nut and welded in place. It had a large one inch drice socket cut off and welded around the outside.
My self I have a 24 and a 48 inch pipe wrench and if the 24 don"t get it I go to the 48. When the 48 fails it means the threads on the axle has failed and it takes a different axle.
I have had two over the years that someone had cross threaded when putting the nut back on and when that happens you will need an different nut and axle unless you can weld the axle back up and cut new threads.
