I've got an older harbor freight 4x6 bandsaw that is probably 20 years old. It's green if that helps, and if I saw lightly, in ether horizontal or vertical mode, it seems to work. If I push on the work like my old saw, it pops the blade off the bottom wheel. I have not gone and replaced anything yet. I did change the oil (first time I think) and took the top wheel apart and put it back together with tighter tolerances. I've replaced the blade twice.?
The top wheel seems to be lined up with the bottom wheel when it's running without pressure. I'm not sure how to check it running. The top alignment screw is tight, and mostly sticks out.?
The gearbox at this point needs a push to get it started, and then it runs well.?
I think it needs a rebuild, but I'm not sure about the procedure. I can't find a manual.?
What ideas do you all have to keep it from throwing blades, and run a bit better?
