I am wondering if I split wood in single digit weather if I risk damaging my splitters. How does the cold affect the metal. Then how does the cold affect the frozen wood. I tried some splitting the other day on some fresh cut maple and I could not split some of the big rounds. 4ft diameter by 26 inches long. It was the day after a very cold night so the wood was frozen hard. I don’t mind the cold because I am sitting in the heated bobcat. But little concerned about the equipment. Oh I am using upside down log splitters. Single two stage wedge and a four way wedge.
