Re: rag joint assembly?
The rag joints are generally not very flat. It makes assembly kinda hard. I assembled every thing in order, tightened them down with light tension then took a large screw driver to push the overlapped metal rings in place. At this point the sprocket is still loose enough to tap into position. Generally I spend 45+min tightening and checking and always end up with a nearly perfect, if not perfect alignment. The joints I have used are cut correctly, but it is the natural curvature you will fight.
