Hello,
I have a Stihl .050" gauge bar. The bar groove measures .058" and appears to be about even to the bottom of the groove so the rails aren't splayed. The chain which is almost new flops around a bit more than I am used to on other bars/saws.
I also have an identical brand new bar and the groove measures .054". The same chain feels much tighter in this bar. I wouldn't have thought that .004" would make that big of a difference in side to side movement.
So does anyone know if there is a specification limit on when a bar should be retired due to groove wear? The only thing that I sort-of go by is the straight edge against the side of the bar test. Of course, the wear is not quite symmetrical side-to-side.
