I have what I'm pretty sure is an old Delta 768 10" 1/2hp bandsaw. I have totally rebuilt it, new bearings in both wheels, guides and motor. From all the pics on OWWM mothership board, it looks identical. There are no numbers or plates on it and it looks just like a shrunk old Delta 14" like I used to have (kick myself for ever selling it!!). Anyway, the original paper on the old Delta, found on the internet, calls for a 74" blade. When I got it in good working condition it had a 72.5" blade on it. Seemed to work ok and tensioned with the flutter method. As 74" blades are hard to find, and 72+" blades are fairly common, was thinking about putting a new 72+ on it. Anybody have any experience with the 768 and blades or blade lengths they would like to share? Randy
