I posted a while back about making wooden axles for an old farm wagon. This is really my fathers project so I am posting this for him. When he was a kid (he is 79 now) this wheel was actually part of a wagon used to haul onions off the muck. He can remember using a large wrench to unscrew the square center. That would allow the wheel to come off and he would have to slather grease all over it and then put it back on. These wheels have been out in the weather for decades and we are just starting to try and get them apart. The wrench is long gone so we are going to have one made up. What he can't remember is if the threads were right hand or left hand? He feels that they may have been designed so they would always tighten but he can't remember. So before I start trying to get these hubs apart does anyone know the thread direction? I would hate to be tightening them the whole time I am trying to get them off! If they were designed to always tighten how the heck am I going to know which direction to loosen them? I am not even sure I can get the square centers to turn, going to take a lot of heat I am sure. If you have any experience with old wagon wheels like these I would appreciate the help.
