I have had this saw for at least ten years and it has always worked well. A month or so ago I broke the blade (again!) and decided it was time to by a new blade for it, instead of brazing the old one together (again !?!?)
I got a Lennox bi-metallic blade... but it was too long! So I had to cut it and braze it (again !?!?!!!)
Unfortunately, when I installed the new blade, I could not get it to stay on the upper (driven) wheel. It keeps walking off the bottom of the wheel.
After much fiddling around I decided that there was excessive clearance in the bronze bushing, possibly allowing the wheel to tilt when applying tension.
I made a new bushing with almost NO clearance..... It didn't help! After much 'poking around', I did notice that there was no tire on the bottom wheel... not sure if there ever was one!?!? I am assuming that there should be one but don't see how this could cause my problem.... only kill the set on one side of the blade.
Does anyone know of a source for a tire? More importantly, does anyone have any idea what may be causing this problem.
Note: as I was typing this, I realized that if, when shortening and brazing the blade, I didn't get the two ends parallel, this could possibly cause the "walking" problem! I have a little jig that I have been using for years and it always worked fine, but it is possible that something moved during the braze operation.
I will check this in the morning, but in the mean time, does anyone have any other ideas?
