In reference to the photo shown: The tiller connector bar or tiller tie bar is in the wrong position. The bar goes on top of the tiller arms not underneath, this will cause the hiking stick to rub on the rear crossbar when sitting on the tramp, also this will eliminate the nut from protuding on the top, as the top of the bolt will be hidden in the larger hole.
