Does anyone have good advice to determine when a chainsaw bar is worn? I just replaced my current bar with a new bar/chain set and now it cuts like butter. It seems I always go past their prime until I recognize when the bar is fried, and this is usually after a lot of sharpenings and a lot of extra time trying to do an easy set of cuts. The old bar does not seem to have that much play in it (side to side), but maybe I'm too generous with that observation. I'm touching up the chains every 2-3 hours with a handheld file + jig, and sharpening them every 10-14 hours. The chains are pretty sharp to the touch. Also I'm filing down the rakers/bumpers to the correct depth.
