I was kicking around the idea of buying a 100' reel of chain and breaking it up myself. I figure I could get in the neighborhood of 22 (20") chains, but I've never done it before. Is there a loss of quality by doing it yourself and does anyone know how much the Stihl NG7 rivet spinner/chain breaker costs? 22 chains would last a long time, but it might just make me so lazy that I throw away dull chains knowing that I have so many more, which would end up costing more in the long run. Any thoughts?
