well, it's kinda hard to explain. but at the other end of the tube, there is a thing with threads for a bolt or somthing in it, so the holes on the bottom of the sticks are really small. so what i did was take nylon cord, and tied a super strong knot, after weaving it through a few links in the chain. then wrapped the crap out of it with electrical tape. the chain goes about 6/10th the way down before connecting to the rope. finally at the other end, i tied another super stong knot, so it would stay in place. then wrapped the ends of the stick in electrical tape, to cover up the knots in the rope. i tested it out, and pulled on the stick really hard, and they didn't move a bit.
does that make sence?
