Having trouble getting my saw chains sharp. I've tried a freehand file with a guide clipped to the file, and a granberg file jig. Neither seems to get the saw particularly sharp. I checked my rakers and they're ok for now.
The trouble I think I'm having is figuring out the depth on the granberg. There is no guide as to just how low I should set the file. The general rule is 20% above the top plate, but trying to visually check 20% of a 5/32" object is not exactly precise.
Does anyone have a better method for the granberg? Would I be better off with an electric purpose-built grinder? I need the most fool-proof method, as my vision is not so good for finish work.
