It was probably 10 years old by then.I have the same problem with a Johnson bandsaw , the cure for mine was to find an inner tube that fit tightly on the wheel diameter ,cut a strip ,glue it to the wheel . due the same thing for the other wheel and adjust the tension carefully .
In the last year it seems like the blade just pops off more often. New blades, spring tension adjusted full tight, bushings still good.
Only thing Ive noted is the wheels do have a bevel to it. Tapers away from the flange. Before I go and "trim" the cast iron wheel, wanted to ask if anyone else has seen that issue. Keep in mind this has had 25 years of service, but still frustrating to be fitting the blade popping off.
If I use the saw in vertical mode... everything works fine, only when I put it to horizontal mode does the blade have problems.
Having said all that the wheel angle and blade guides have to be perfect , as well as the tension on the stand in horizontal position .
Mine has an adjustable weight to allow for different types of materials .
Good Luck , hope this helps .
