I have a roughly 30' diameter red oak that I can get a good 16' length I would like to mill. I have a Stihl MS 271, which is 50cc that has a 20" bar. I was going to put a 36" bar and buy or grind a ripping chain. Would this kill my saw, or could I get it done if I took plenty of breaks and let the saw idle and cool off on a regular basis? I would probably rig up some auxiliary chain oil system as well. Any tips, tricks, or advice welcome.
