Anyone know what the allen screw is for in the centre of the shaft that the blade fits on, and where the large retaining nut is on an old, and I mean old, Super Brown saw.
Another thought is why do they make so many groaning noises and what can also only be described as vibration type oscillation noises. This happens even with a new unclogged blade?, but not on every cut?
I guess worn parts is an obvious answer, but on some occasions, when cutting the same material, it glides silently through the job? Bob
