I was getting some noise out of my "no name" band saw and took the upper end apart. Found the tension block cracking where the upper wheel assembly pivot pins fit. You can see in the first photo where the pin fits into the tension block. It is pot metal and it just wore out or I got to heavy on tension knob sometime in the past. I don't know much about the machine as I bought it used 20 years ago, and it looked old then. Does anybody know where I might find used parts for my odd ball saw? I broke the trunnions when I first bought the machine (lifting it in the truck wrong) and found parts to an old Jet fit there but I'm not sure if all parts are interchangeable. Any and all input would be grateful.
