territorialmillworks Posted October 9, 2011 Share Posted October 9, 2011 My hammer has a 1" rod which screws into a 'bung' style nut welded to the ram. I have a jam nut on top of this as well. Even though I clean the threads and use locktite, it still loosens. I thought about drilling through the nut and rod and putting in a rolled pin but was worried about weakening the rod and having a stress fracture . Another idea that I used years ago was to drill and tap a hole, place a short piece of brass rod in the hole to protect the rod threads and then use a set screw to pinch the rod. But I think that there is just to much vibration for that to work well. Quote Link to comment Share on other sites More sharing options...
