I’ve been dealing with lung damage for a long time now. Dirty two stroke engines can send me into serious coughing fits. The coughing can be so bad I pass out. That’s not something you want to have happen with a running chainsaw in your hands.
In spite of that, over the years, I’ve gathered a lot of my own firewood. Fortunately a lot of wood can be gathered within walking distance of the house. I drag whole trees to the house where they are cut up with a corded electric chainsaw. Usually my 120 volt chain saws are ordered special so I can get more powerful ones than they normally sell in stores.
For a few years I had a F250 pickup truck with a 7.3 diesel that ran on waste veggie oil. I wired up a huge inverted to run my 120 volt saw. The Forest Service sells permits for dead and down wood. There’s National Forest land nearby with a lot of dirt roads. With 100 foot cord it wasn’t too hard to quickly fill up the truck with wood. If the trees were further than my cord was long it wasn’t worth dragging them out anyway.
I’ve never been one to trust the availability of petroleum products. Maybe it was due to coming of age during the Arab Oil Boycotts. Sometimes it’s good to have an old school backup. Mine is a 3.5 foot German crosscut saw. If you have to go with manual power, don’t scrimp on cheap saw. Make sure you know how to sharpen and maintain it too.
In addition to the hand saw there’s a new Toro 60 volt battery chainsaw. That saw does a pretty good job. If the grid goes down it can also be charged on my household solar electric.
One nice thing about gasoline alternatives. They are much quieter. That can be important during interesting times.
