I was just thinking on building a shed for my boat! That just engineered the whole thing right there!!! :stacke::stacke::stacke::stacke:
I'm a cheater. Trying to stack 15 cord/yr, I try to maximize time and space efficiency over ideal drying conditions and neatness. Much easier to just load the racks for me than try to make nicely cribbed ends. Though I did crib a row in the back of the pine stack this year to keep the weight off the bookend when I noticed it trying to lean a little. It was a fun exercise, but I'd be there forever if I did it with every row. All that said, I have a ton of respect for a nice neat cribbed stack (and its builder!) and love seeing the pictures. Some day if we go with an indoor stove I'll have to stack differently to get more airflow, and may try my hand at some freestanding rows.
....Well I retired my stacking days after playing 52 card pickup too many times. Since I'm 3 plus years now, I've been stacking in between skids in dimenstions of 8ft by 20 ft sections...
I think too many are thinking too much on this and for sure trying to get all 3 splits the same thickness to me is going too far. You don't have to be that careful. Just make them similar but not nessisarily the same. Here's one picture I picked out for you to see that you don't need a level to stack wood or crib ends. Just look at how sloppy these ends were put together and yet they lasted 4 years with no problem. And yes, I checked. Those stacks were made in 2009 and this picture was taken in 2013. Nothing was done to the stacks until they were burned other than top covering them.
Not sure if it's been mentioned but Eric from Life on Farmland has a good woodstacking video (also a bunch of other firewood vids). Must see watching for any firewood junkie
