Some times on the tension, I get it all together and it doesn't seem to adjust right. Then I take off the end nut, give that inside nut another slight turn and put it all back. Sometimes that does the job. Some times I have just turned the dial over and it worked fine. Tweaking the tension is more of an art I fear. Maybe the art is messing with it until it works. When it works it is SWEET. Some times they go back together just as pretty as you please - then some times they want you to fool around - usually if you don't have much time...
