No Mike, I didn't buy a Hayes. Think smaller with a lot less tires....
RW, yeah I feel your pain with things taking forever. When I made the diffs for my KW I was pretty stressed. With one completed my mill fried it's board so that added to the fun. Hopefully your bearing hangs in there. Once this hurdle is over there will be another and another and then it will be complete and you'll be bored and start something else that challenges you in a different way. It's a vicious circle for us scratch builder types.
