I started with a need and an idea. I gathered up mostly reclaimed wood and built a small solar kiln. Started with a shipping crate and a few leftover 2×4s but did have to buy the plywood and plastic. It measures about 3’ deep x5’ wide x4’ tall. It is now sitting by the fence facing south and drying wood for free.

Solar kilns are a great way to dry lumber and get very good results, I have put over 2,000 bd ft through mine with very good results. You may want to consider adding a small fan to move the air and adding vents in the back panel, top and bottom to bring cool air in from the bottom and to expel moist air out the top.

That is a good solar kiln and one of the nice thinks is that you can make it any size that you need.
I have a 12×20 storage shed that I dried a lot of sinker cypress in by just putting a fan and a dehumidifier in. It brought the wood from nearly 60% down to around 8%.

Thanks for the comments guys. Doug the vents are in just not in the pics and a fan will be installed later. It will have to be solar as well since there is no electricity near the kiln. I have a drying shed in another spot which handles the larger pieces and logs if I can manage to get them in there. Nothing like free drying.

Wow. Never thought of building something like this. Probably better and quicker than stacking it in my barn loft! I might have to try this.
