I’m a beginner firewood hoarder been running saw for a while, mainly trash cleanup and property maintenance. Any tips on how to cut perfect fireplace length every time? I haven’t done it enough to be calibrated, my dad was legit he could cut 100 sticks and probably only be off 2” me my little woodpile looks like dog crap….and I’m a bit ocd so that doesn’t help….thanks..I have a stihl 261 and a KM pole saw so trying to make the most of those investments…
