Ah, the old argument about how much wood is in a cord... I've heard up to 30% air in a stack of firewood and that supposedly came from some university. The part about the university I do not deny but knowing how they do things they typically took a bunch of kids that have probably never stacked wood and had them stack then did some exact measurements of the wood after it had been stacked and came up with their figure. I've for sure seen some wood stacks that very well could have 30% air but to say that all are like that is pure baloney or BS, whichever you prefer. Another point is that if the stack is measured when green, then perhaps they could be close. For example, if we stack green wood at 4 1/2' high, say in March, then by December we find that wood to be only 4' high. So, when do you take the measurement of the cord? Before dry or after drying? And for someone to tell me my wood stacks have 30% air, I call BS right off the bat. But I can't speak for everyone.
There are areas where wood is sold by weight, complete with different weights for various species and green or dry . So an example 128 cf of green Oak = 8000#, dry at apx 20% moisture content 5000#
I've read this before I think this picture explains it well by Paul bunion This is a stack of legos with 30% airspace. I have seen a lot of stacks in great pics by members here. Maybe by a rookie that did not know how to stack. But a woodhoarder..
Excuse my opinion, but that doesn’t make sense.. If you are good at cutting and splitting, stacking should be a breeze... You must be deficient in one, the other or both... after losing some stacks, I studied Backwoods Savage ’s stacks and changed the way that I cut and split... My stacks are formed with the chainsaw and splitter before the first stick is placed on a LEVEL pallet...
Another great example stuckinthemuck I do not see 30% air in your stacks either!! maybe in the cribs.
Actually, there’s probably around 40-45% air in the cribs... most of my crib splits are a little less than 1/3 of the width of the crib.. so the space between them is wider than either individual split (for the most part). none are perfectly square and they are cut to 18-19” and placed on 40” wide pallets... I do occasionally fill in some of the gaps which would probably bring the cribbed ends back down to 25-30% air..
Very nice and neat! I need a lean-to with sides to be able to stack muh wood. If not, the pile falls over. Lol
Thanks I can see it varying. A large tree is going to be closer to the 90cuft and small tree will be up around 110cuft. I'm cheating, I have an app that does it for me. I input the length and diameter and it tells me how many cuft. If I measure 3 log, it will tell me the total. I just want to be able to closely estimate how much firewood is in a log. I'm cutting tree for firewood on another guy and I would like to get at least 30 cords. If I am figuring 128cuft as a cord when it is really 100cuft, I'll be way off in the end, which more wood would not be bad.
