I noticed Bailey's has some 16-20" narrow-kerf .325 pitch bars on clearance for cheap, so I was thinking I would pick one up (with a matching sprocket) with some ripping chain and see if it made much of a difference in milling. But the only ripping chain I can find of that size (Oregon 95R) doesn't seem to be available any more, and the Bailey's rep seemed to suggest that .325 pitch itself was going away. I can always regrind regular crosscut chain for ripping, but is it worth my time? Is narrow-kerf chain going to be noticeably faster? Can the thinner bar hold up in milling, especially since my small-log mill only clamps at the base of the bar?
