I mooched free, decent Pallets from the local hardware, then lined them up, bolted them together, fix any broken cross-boards, and set it on some sidewalk slabs. (the soil is dug out, filled with sand and gravel, tamped, leveled then the sidewalk slab one in each corner front and back, and one at each joint front and back. I only need 2-3 cords for my workshop woodstove.
SO 5 pallets give me 20 feet. I save one 4x4 section for kindling, and the rest for split dry wood. I sink posts all around, face the long side west (since I get south winds thru the summer. I cut some 1 x 6 strapping on my mill and nail it to the east and north facing sides. That's where our winter winds come from, the other sides I strap but leave 6" spaces so the warm winds can swirl around inside. The center sector I hinged up a sheet of old plywood, (for a door), so I can get at it. [ I used to just staple a tarp through a long stick. to the pallets then flip it over, but like someone said, a 70 mph wind comes along and tears it all to shreds.] And that's several time a year where I live.
I had the pallets, had the old sidewalk slabs the sand, the gravel, the old plywood, the hinges, made my own posts and 1x6 , Hired a young beast to auger the postholes for me, Took him 4 hours to do 10 of them 3 feet deep., he asked for 80 bucks.
I decided (at a later date) to replace the 1x6 strapped roof, with some leftover metal roofing that I bought from a neighbor for 100 bucks, and made it like a hinged lid. I was thinking," I'd lift it up on hot days and let the air flow". It definitely keeps the rainwater out better But I think I lifted the roof one time in the last 4 years.. it's completley unnecesary.
SO, I should have left it as it was. (It does look nicer than strapping butted together though.Happy wife Happy Life.) Also firewood can be too dry as we all know,.That new roof was overkill. Shunnadunnit.
SO....Aside from adding firewood once a year in April. I haven't had to touch the thing at all. Yjis is like 7 years or so, now. No more tarps no more dirty muddy hands or clothes, no more banging 2 pieces together to get the snow off, and smashing a finger in the process. I vote for a structure over the tarp game. Done both, Like structure better.
