I'm having a very difficult time installing the rag joint on my 72-spoke wheel with a coaster brake. The brake arm is off and therefore out of the way entirely. I just can't get all 9 bolt holes to line up with a gap between the spokes at the same time. Anyone else had this problem? Maybe seeing a few pictures of a 72-spoke wheel with the rag joint installed (from the opposite side of the wheel from the sprocket) would help. This is my first build, by the way.
