While processing firewood is a lot of grunt work you can do very well for yourself provided you possess the necessary equipment and most importantly a good engine ... Strength and stamina are needed in large quantities if you are going to produce at a level to profit nicely ... Anyone can bust their c..k for 15minutes ...... Can you do it for 4+ hrs and (given rest) wake up the next day rinse and repeat ? If not then doing it “old-school “ by hand / hand tools might not be for a guy ... Guy up the road owns a tire business and processes logs into usable product. He easily sells 2500 face+/ yr at 100 a face ... Log processor makes about 10face/hour and a conveyor makes piles that dwarf whatever meager amounts shown here ! If logs cost 40/ face and You sell for $100 that’s 60/face (minus cost of fuel , maintenance, upkeep etc) profit .... Even after all’s said and done if ya net $35/face (not unreasonable) and machine produces 10face plus that’s good $$$ , especially for “unskilled work” ... The “skilled work” is being able to design , fabricate , machine, weld etc to keep “SUGAR” runnin like a well oiled machine
