Yeah, but you're milling granite. But seriously, some time ago I changed my sharpening around to the raker angle notion you have mentioned before. I went so far in testing to grind cutters different lengths and rakers different heights, as long as the angle stayed the same. As long as I didn't get too crazy with it, the chain still cross cut OK. The trick now is working out how far i can push it in different woods and uses (steeper raker angles for bucking for firewood compared to felling in the same woods, for example). Thanks for the raker info. That original thread was one of AS' gems.
