Задняя часть лезвия не была полностью выровнена при сварке, поэтому лезвие перемещается вперед-назад при сварке (у меня есть видео about that). Sawing the back of the blade would have made it worse so I carefully adjusted the rear blade thrust bearings and everything works fine. I don't have to send it back. but i was a bit disappointed. I really liked the information on how to set the blade tension correctly. Not only did it work, but it turned out that my Craftsman band saw was properly calibrated, at least for that particular blade. It's the only attitude I've never felt comfortable with.
