hello, i have a craftsman, 10 inch 3 pulley bandsaw- mdl#113 283 270c. I need a diagram of the blade set up.... bought it used, with no blade. I'm trying to install a blade, but 'as it is' set up - the blade wont rotate without hitting two liitle allan key screws below the metal pulley - a picture would be nice. (I don't know all the part names - just wanna cut, not be a tech) thanks
