On an impulse, I bought a very cheap chainsaw mill (Alaskan sawmill) on Amazon just to try it out. I'm planning on using my Stihl 462. I have 20", 25" and 30" bars, all with standard full house chains. Would it be stupid to try milling with a normal chain? Should I definitely purchase a ripping chain first? I would probably be milling oak or beech. Also is it best to use the shortest bar possible or is there any advantage to using the longer bars even on smaller logs? All advice welcome!
