I bought a small Stihl Chainsaw, MS180c.
That is a small one, but very high quality. Uses the skinny chain, 16" bar.
I bought an extra chain, a small can for the fuel mix, with the nice pour spout with the on button for pouring, and bar oil, plus the extra guarantee that comes with also purchasing their Bar and fuel oils. All told it was a good investment.
You have to know your tool well.
These things do use gas, fuel oil, bar oil, and need sharpening every 45 minutes or so. Not sure if some folks realize how much work it is to get a cord of wood.
You have to get the permit to cut wood, have to cut in certain areas, get busted if you cut in the wrong place. Have to drive your pickup through places with little or no road. Have to go trapsing to the tree, have to study the tree for the fall, watch out for hangers where the felled tree hangs up on another tree. Oh yes. Then you have to do loose cuts. You have to always be in top form. Tired, you stop. If you don't admit you are not 100% something goes wrong. Ya have to cut some rounds and load them in the truck and repeat. At least it smells good and the scenery is great. Ya have to cut trees of a certain size or condition or kind.
Someone's wood costs less than 100 clams a cord. That's cheap.
Ya have to empty your pickup and split the wood. Hydraulic splitters are nearly as much work as a good maul.
Then, ya have to stack your split wood to cure for a few months, tarp it if it's gonna rain on it. So, ya have to store it before selling it. Then, ya have to talk to the customer who wants the best wood you have. Then ya have to load the truck. Find their house driving there, offload it, go to their inlaw's house to get paid, and they act like you're suddenly rich.
From there ya go to the hardware store after the bank so you can buy a new bar for the chainsaw because a hanger crushed the old one. While there ya get a gallon of bar oil and some more fuel oil.
Then ya count your money, look at your grocery list and shorten it, go to the grocery store, then drive back up the 16 mile dirt road home.
Gotsta love it!
