I have a 72” cannon SawMiller powered by 2 660s and it seems to be hard on chains (Oregon 59 skip .404). I just started running this setup and was running the chain “snap” tight and you could still pull the chain off the bar a half inch or so with a normal pull. Seems to me that’s where it should be, a little tighter than a shouter bar. When the chain got hot and expanded it would jump around a little bit etc. I don’t think I was driving the saws into the wood too hard. I ended up breaking the chain twice in a 48”- 60” wide by 12’ long piece of Douglas fir. I also broke a drive sprocket. I’m going to try a new chain and new sprockets and see how that goes next week. Just want too see if anyone with experience running these double ended long bar setups had any advice on the abuse of chain and bar. Also, the chain did not break near spun on master link in both breaks.
