heck there's firewood sellers down here that can't cut uniform. i agitate the firewood sellers at the hay /firewood auction i go to by walking around with my 16" measuring stick and checking loads. some don't have a clue how long to cut. just because they burn 20" stuff they think that's the norm.
A few years ago a friend of mine had a big pile of logs milled up in the spring and he cut up all the slabwood , fall rolls around and he decides to sell the slabwood , figured 50$ was a fair price for 2 truck loads .
An old fella calls him and asks how long were the junked up pieces , 12" my friend says .
That evening the old fella and his wife show up ready to buy the wood , looks at it and pulls out a tape .....10" to 16" , the old fella explains a cookstove and how big the firebox is , 12" max .
My friend thought about it for a second , told him he could have the wood for free for coming out on misinformation , the old fella was more than happy and thanked him .
