Hey guys, I was out cutting on Sunday and the cut was always crooked, found out the bar is worn out. It is a .50 gauge bar, bar is straight so really didn't want to get rid of it, my brother runs .58 gauge on his jred and he tried it in the bar and fits good. Tried it on the saw and goes nice and straight. So a worn out .50 is a good .58. Saves money on a new bar.
