I had a 5 footer (sunk in 1ft) that failed after woodchuck went through there. Replaced that with a 6ft The rest are 6 foot sunk In two feet, they did bow out and blocked my little walkway so I wired the tops of them this time. It depends a lot on what soil you're putting them in. I don't care for cribbing so I use whatever else I can so I don't have to do it If you want something free to stack on you can make some racks out of pallets, that's what I did Instead of buying more posts ,only cost is deck screws. You can even put tops on em and make little wood sheds
I've got about 6 of those 6 footers around and only one now in use. I've just got to the place where I hate those darn things, it's either crib'em or nothing.
Pretty much the same as a few others here. 6 1/2 footers driven in about a foot and a half with some fence wire run between them. Only down side is the expense of the posts. I've got about 50 of them now and I'm hoping they last a very long time.
Looks great Bret. They sure aren't cheap though are they. I was lucky that the previous owners of the house had left a bundle of them for us when they moved - I wanted a couple more so I bought a five pack at lowes without looking at the price. My jaw almost dropped at the checkout.
We still use the t-posts for fence posts here. We have mostly the 7' and 8' posts. Also use the 8 footers for stretching netting on to keep birds out of berries.
Shawn, I have only one concern with your stacks. The tops of the stacks are not even and you have ups and downs in the covering. Quite naturally this will send lots of water off those low spots. Question: where will this water go and will it hit the wood? Even if it hits only the outside few inches of some wood below it, over time that part of the woodpile can get water-logged. So just beware and double check keeping the rainwater in mind and picture what is going to happen.
I tried to make the rear stack slightly higher than the front, so that the water would run off away from the building, instead of getting trapped between the building and the stack. The vinyl also overhangs the front of the stack a couple inches. I probably do need to do a better job evening it up. It seems to be staying high and dry in the front of the stacks, but of course you can't see the back. I will take your advice and double check them. I was all out of splits at the time, but now I have some more ash and black locust to even things up!
