I have a 14 inch Delta band saw with a 6 inch extension. I made the mistake of buying a 3/4 inch saw blade when buying a band saw. All my reading and experience since then has convinced me that a saw cannot handle such a wide blade. I couldn't get the 3/4" saw blade to move properly on both wheels at the same time, probably due to saw frame over-tension. I've bought Olson 5/8" and 1/2" blades and the 5/8" blade works great too. I haven't tried the 1/2" blade but expect the same result.
