I have the old 1950’s 12″ Craftsman bandsaw pictured above It has worked fine for years I am now going to put new tires on it & would like to get a new tension spring. Does anyone know where I can get a spring for a 12″ saw? I’ll be keeping a 1/4″ or maybe a 3/8″ blade on it. I have a 14″ saw with riser block for sawing larger work.
