Hi Don, I`ll see if I can help but I`m sure that others can add to what I`ll say. First, when using the breaker, make sure that you center the punch over the rivet and support the chain so there is no deformation. When forming the new loop, make sure that you use new straps and presets of the right pitch and manufacturer, sometimes there are minor variations, also make sure that the reliefs on the straps are facing down, or inside the loop. That`s pretty obvious but it may get missed. You have to ensure that you have the right anvil in the spinner for the pitch you are using and line up the wheels so that the chain is held in the right place relative to the spinning anvil and the tension handle. I usually set one rivet just a bit to hold the tie strap in place and then move to the next rivet, fully forming it, and then moving back and finishing the first rivet. Use some type of lubricant while you continually increase the pressure on the rivet as you spin but go sort of slowly on the pressure, you don`t want to expand the rivet so much that the drive links bind, then just spin the rivet down, using oil, until the head looks good and is at least flush with the others, not higher. The expanded rivet in the straps is what holds it all together, not the head but it might as well look good. If you just can`t get it right, it could be the spinner, I`ve heard some of them don`t line up right, but I know from experience that the Oregon, or the red ones Jeff sells, work very well. Russ
