Re: Wide bandsaws centre cracks

Kevin, One of the main reasons bandsaws get(body cracks)is too much tension in the middle of the saw.The cracks are generated from the saw flexing up and down every time it passes over the guide block and since there are two guides that's alot of flexing.If your saws have too much light under your gauge try going out to the front and back of the saw and pull some out,keep in mind that any portion of the saw that shows light will be the last area to tighten up as you strain your mill up.Also keep in mind that this will not change your tirelines if done properly done.I have seen saws crack anywhere a number was stamped simply because that was the weak point and not because it was stamped to deep.All the tension that is needed is just enough to let the tirelines tighten up first,some think if they open the saw up alot they won't have to bench it after each run but those who have body cracks might just disagree.Imagine bending a saw back and fourth as many times as it goes over both guides until it breaks and you will have recreated your results. Hope that helps, Kenny Cleveland..........
