I am going to do a readjust of all the turning things prob tomorrow and get the push down of guide roller to under 1/4" ,check parrallelity etc.

I know nothing about a Norwood, but I feel sure this will cure your ills. Exspecially the roller guides being that far out from each other.

Reporting back after a long silence. I did adjust my wheels and rollers so that guide rollers are 1/4 inch below plane of wheels. This has definitely increased blade life, Im up well over 2500 bf on a blade now and no sign of fatigue or cracking.Previously I was getting abt 1000 bf. The advice given by forum members on this topic was extremely helpful.Thanks.
What I did notice on this woodmizer double hard band, the first one I have ever got that much life out of, was that when I set it this time(after 2500 bf,approx 10 -12 sharpens,) was that it took way less overset to achieve my objective of around 27 thou.I was pushing to 100 tou,it would spring back to 28  this time I did whole band to 100, then realized teeth had set to abt 35 thou. Proceeded to grind anyway and it cuts ok. I guess the double hards are not as hard when you get past the good part. Anybody else have this experience?

Coasty,Iam a little late in this fray but a couple of comments.Do you throttle back or dissengauge the band when loading logs or turning cants?? Idea is to reduce the fatigue a band can only flex so many times.Tension should be just as much as needed.Inspect a broken band if there are alot of cracks in the gullets its fatigue from too mang turns or excessive tension if band has no outher cracks probibly damaged by tramp.Some band lots are harder and more brittle than outhers.Alignment plays a part too if a band if flexed forward and back its life is greatly reduced,its a wonder they last as long as they do.Frank C.
