Band saws are for making bowl blanks round, but for me seldom is it worth the time and trouble. When sawing a section of log into blanks, the corners can quickly be knocked off with the chain saw already in hand to make octagons. I don't have to move the band saw, remember to tighten the blade tension, diligently clean all the wet (green) wood from the band saw table and compartments, and scoop up the pile of wet sawdust on the floor. And between push and pull cuts, an octagon can be made round on the lathe in just a few minutes. My two cents.
