Wood Fired Kiln From a Shipping Container for Drying Treating Wood

- I built a wood fired kiln out of a 20 foot shipping container. It uses a wood stove to heat the kiln from waste wood. It easily reaches a high enough temperature for treating wood to kill wood boring bugs. I used it for treating wood for export. I was able to build this kiln for a relatively low cost.  I built this for treating decorative branches, but it could be easily modified to use for drying lumber or firewood. I cut lumber on my Woodmizer LT15 sawmill. I mostly cut soft wood so I haven’t used it to dry any lumber yet since I prefer selling it green.
This kiln replaced one that I previously made out of an RV trailer. You can see that video here.

Something I should have mentioned in the video. This was designed to be used with the container doors on the wood stove side open. I have a stove pipe contraption that goes into the stove pipe going through the wall that vents the smoke up and away from the structure. When I shot the video, I had that stove pipe off so the doors could be closed while I wasn’t using the container.
Awesome, looking to build a small one myself for drying logs
Wow
Silicone caulking is good to up to 500 degrees. You could use 12 volt solar power for circulation fans to increase the volume of air moving around the interior.
Hey I really like your work attire. Where'd you get that shirt and how's it hold up? Thanks!
I like the look of those shirts but I had to stop wearing them because they shrunk so much after washing them a few times. There were also a couple seams that ran down the front that were uncomfortable and abrasive. I had to wear an undershirt with them. I ordered them online somewhere but I don’t remember where. I am still looking for another alternative like them.
@@WilsonForestLands do let me know if you find a good one! I love shirts like those, but they either cost an arm and a leg or last about 2 uses.
Have you considered the heat powered wood stove fans? They are very useful in canvas tents for moving air around when there is no power.
They might not work, due to how they work. There have to be a temperature difference in the air and the "heat source". If the air is to hot and humid, both the motor and the peltier device could be broken. Good idea though
Mr. Wilson my husband is a retired contractor, he said your approach to simplicity is far better than a custom built unit done by an experienced carpenter, It is practical, effective & well made. He wants to share a test that was done on OSB plywood on site by a manufacturer representative, in Southern California. There was a newly framed house with OSB installed on it already, so he took a plumbers torch and held its flame towards the plywood. He said the plywood started to smoke & the surface was glowing, he then took the flame away and left the smoking plywood. The burn did not spread from the localized area and eventually cooled down & stopped altogether. That is what was done during the height of OSB use.
I appreciate you and your husband‘s comments. That’s an interesting study, thank you for sharing. That could be an interesting experiment to try and confirm.
Great video. I would love to hear the entire story of your branch drying business. Maybe you could do a video on that?
It's not a labor shortage. It's more likely a pay shortage.
A possible solution to the off-grid fan problem would be computer exhaust fans. Very low power consumption and if you mount several together in a DIY frame to fit the hole, you could run all of them to a solar panel and rechargeable battery and have enough power to run them 24/7. Not going to be real powerful, but certainly enough to vent the cooler air out.
That sounds like a possibility. I wonder how well they hold up to moisture. I didn’t go solar because when I was using it, most of the time it was in the winter when we don’t get much sun here. If I start using it again for something else other times of the year, your idea would probably be a good one.
@@WilsonForestLands That's the better part of using the computer case sized fans. They move good air, but tiny power usage. So, small solar panels would work and a small battery would supply what was needed and depending on the panel, it can even collect ambient light for enough juice on overcast days.
@@WilsonForestLands they are so cheap, even if moisture was a problem, most likely still cost effective.
They make heat powered fans designed to sit on top of wood stoves. Those might help with circulation
That looks perfect for making beef jerky. :D
Lots and lots of beef jerky! 🤪
Actually I think it's the americans who largely mispronounce voila as "walla".... French and French Canadian's pronounce the "V" properly. It sounds ridiculous everytime I hear an American say "walla" 😅. Pronounce the V softly followed by the "W" sound. Good Video though. Thanks for the content
But good video. Thanks for the content.
My wife is a reptile-owning veterinarian. I'd LOVE to know more about your decorative stick business and how you go about that.
More like how I went about that since I quit doing it. My email address should be in my about page if there are some questions you have. I have thought about talking a little more about the business on video and some of the lessons I’ve learned. I’m not sure how many of the viewers on this channel would be interested.
Great idea for a kiln, I have been thinking about making one out of my extra shipping container. Are you using as a kiln still
Nice homemade kiln. Not something I'll ever build. A container would be pretty nice for storage to keep things out of the weather. Some have even made tiny houses out of containers.
Exporting decorative branches??? Tell me more.
Do you think something like this would work as a very large food dehydrator?
Another question: OSB is still pretty expensive, whereas sheetrock/drywall is still pretty cheap. For about $20 USD, you can get a 4x8 sheet of moisture/mold resistant drywall, which is much better for fire resistance than OSB. Would that be a viable option for the inner sheathing?
Now that looks like a really nice kiln setup. I like the double doors. That worked out great for the wood stove begging to be able to reload without losing the heat in the front department. Thanks for sharing it. Great job. Take care
That is interesting...I too have not been able to find helpers the way I could years ago. I have to change with the times. tHanks for the video
Ove everything about this So much.
solar fan ??
Love your truthful humor
Thanks, I appreciate the comment.
So there's no way for moisture to escape? No air circulation? Wouldn't that make it a sauna rather than a kiln?
Nice build! You made me laugh out loud with "VO-ILAH!" Subscribed, based on that alone! For decades, my brother and I have been using "VIE-OLAH!" after accomplishing a feat worth bragging about. Imagine my chagrin when I just realized that we've been mispronouncing the mispronunciation! SHAME! [hangs head]
I have one 40' conex for oddball wood (logs and weird firewood pieces I want to turn into sculptures) as well as just standard storage of regular junk and things that were building up in the garage. With the stuff I build, I mostly just let the wood weather and season outside like you would with firewood, but the fancier, "special" stuff I put in the box I treat with Anchorseal and let it slowly dry out in the WWT box. The value of utility for the cash outlay is amazing with shipping containers!
I have room to put a second 40' unit in right next to it on the back property. Do you think I could separate like the back 16' or so and build a similar situation like what you have going there, whilst keeping the front portion for more standard material storage?
Also, here in Texas, most months the inside of my current box gets pretty warm from just sunshine and downright scorching (120+ degrees) in summer. i would imagine I could get away with a space heater type situation in the actual kiln room for the couple of cold months that we might have, or even just a fan to maintain the air flow without worrying too much about temperature. Thoughts? I don't know that much about kilns.
I'm planning on building a firewood kiln soon. Wood furnace heated , hot air blown into the chamber with 2 high cfm fans to dry the firewood in ibc totes. 2x6, framed with spray foam. Sheet metal exterior. Seperate room for the furnace. On concrete so I can use a pallet jack and skidsteer to move the baskets around.
Sounds like you have the right idea there. The hot blown air should do the trick.
how many lbs of deer jerky could you make at a time? or any jerky for that matter?
Very good question. Maybe the question is, would it be pounds or tons? Either way I know it would be a lot
looks fantastic Great job, even with all the rush work and temp fixes it still came out perfect. once you solve the venting issues you can kiln dry anything.
There are these heat powered stove fans (they have a little thermo-electric element in them, quick search says they are about $40), you could probably take it apart and put the heat to power part on the outside and then run some wires to the fan part inside for better performance.
Should have started with an old refrigerated box. They are already insulated and have an aluminum floor, so they won't rust.
Next time buy a refrigerated container it's already insulated.
As far as the standing wobble goes...you didn't have a power saw in your hands, so it doesn't count.
Humid air is lighter than dry air. You want to vent this at the top.
your already a step ahead having this, i would pick out special woods you've cut ,and kiln them to fill another container.
Mate just want to say, one of my favorite videos. If I wasn't in Australia I'd ask to come shout you a few beers
Without a fan how the drying can be even through out ?
Use a solar panel from harbor freights to power your fan...
How long can freshly milled lammber take to dry
Your link to the RV kiln is to this video, not the RV video. FYI :)
Turn it into to a sauna!
Cold plunge tub outside
If you would like you can ship it out here at your expense to get rid of it 🤣 All kidding aside, it looks good, perhaps a solar powered fan or two.
That would be really nice of me to do that, but I’m just not quite that nice. 😁Solar fans could be a partial solution. I probably would do that if I was to start drying lumber now. But for what I was using it for, the time of year I needed to use it most, was in the winter when we usually don’t get much sun.
you should klim dry firewood to sell in usa and out of the countury
Great video. Do you think this would work for firewood?
If you get really nice vertical grain fur they like setting the pitch in that then using it inside that way the pitch won't run. That would work great for setting the pitch.
Good suggestion. Eventually I will get into more material that is more clear with tight grain. I would then have to see if the value added would bring in a price high enough to make it worth it.
I see you're familiar with the old adage "There is nothing more permanent than a temporary solution that works." LOL How about kiln drying firewood? Load them up in IBC tote cages and put them in with your tractor and pallet forks.
I like that adage. Firewood is a good suggestion but firewood is so cheap here its hardly worth messing with. I have dried a little for my own use when the cover blew off the pile and it got rained on.
Oh and you could always offer the option to kiln dry lumber for folks for a fee if they are buying enough to make it worth doing.
If I ever got back into selling lumber that could be worth trying.
Looking at where the smoke comes out unless you cut a hole in the door they would have to be opened while using the kiln. is there any thought of cutting a hole in the door (s) for smoke escape? That could be a dummy question but I don't know how say what I'm thinking otherwise. I do like you videos and your sense of humor.
Not a dumb question, when I was editing the video I was thinking I should have clarified that. It was made to be used with the container doors open on the wood stove side. I have more stove pipe that goes into that hole that vents it up and away from the structure. I had the stove pipe off so the doors could be shut while I wasn’t using the kiln.
Love your kiln set up nice and simple while also being functional, if it works don't mess with it. You could put a bit more heat resistant insulation along tipoff block wall the might help reduce or stop the air leakage between them and the metal section of the wall.
Yeah that area around the blocks could use a little more work. Probably just a little insulation stuffed in there would do the trick.
Very interesting and intriguing design, thank you
You could let me have it.. I need one so bad. Il work for you I'm pretty good with a chainsaw ( stihl 500i, ported echo 590 24incn bar and a little Husqvarna) carpenter/ framer by trade, not young anymore but I need your knowledge and your kiln lol 😉
I quit that business so I could do things where I don’t need people to work for me. I have a few ideas for things I want to do with it. I just haven’t decided which one I want to do the most.
Start drawing firewood
Hello I am Marius you have very nice jacket I would like to ask you what is it ?
Thank you Marius. It is a Carhartt and a while back there was some discussion about it in the comments on one of my Shorts videos. Someone said the name of it but I can’t remember what it was. If you look up Carhartt J284 MOS you should be able to find it. That is the number on the label.
It looks like you put a lot of work into building that kiln. I don't know if you need more storage space, but if you do, it would be nice for that. I wish I had one of those shipping containers. Thanks for sharing 👍
If I don’t do anything else with it it’s probably going to end up storage space. But that’s the problem with storage space, when we have it we end up filling it up with junk.
@@WilsonForestLands I agree 100%, I have way to much stored junk :)
Just call it a "Tiny Home" and rent it out on a vacation rental sight. How long is the container, that size seems just right.
A tiny home is one of the things I have thought about most for it. This one is 20 foot. It’s a little smaller than I would like for that but I think it could be done.
What I want to know is did you wear safety glasses while building this kiln😂. Nice work and it looks functional
I did while running the circular saw. And I wore what was practically a spacesuit when I put the insulation in.
I always say; "viola".
Mr Wilson sir I thank you having priced out a kiln from Nyle, I was in sticker shock !! So I’ve decided to buy their dehumidifier kiln set and then build my own container kiln. Really liked your double door system though and might incorporate that ideal into mine. Again thank you and keep ‘em coming !!
Including the container I probably don’t have more than $5000 into this one. Hopefully you can get some ideas from this one.
How about some foam rubber pipe insulation for between your doors
That might be a good idea. I haven’t been using it as a kiln in past years,but if I do, I will keep that in mind. Thank you.
Wow
Wow
Firewood
Very nice 👌
It's good to know the OSB has held up, I've been curious myself about building a kiln and since shipping containers are super expensive I'd probably just build a normal building out of lumber. I guess the key is to monitor temp so it does not get too hot too. Would be cool to pump the heat through some pipes in the floor and make the floor concrete, it would retain heat and slowly radiate it up.
I thought about just doing a normal building. But I was in a hurry and also was considering the wild fire danger we have here where this one is located. I wanted the ability to close it up if a wildfire threatened it from the outside or if it caught fire on the inside.
I was thinking of using insulated sea container with wood boiler providing heat to infloor heating to dry firewood with an exhaust fan near the top to blow out humidity.
I'm wondering how it would work drying firewood
probably just fine. imo, firewood dryness is a matter of timing and pre-planning. let mother nature do the work for you.
Great job Wilson, did you surface the floor with metal?
No, the floor is just the floor that came with the container.
@@WilsonForestLands that is metal?
@@snickersberet4792 No it's actually made out of bamboo.
Do it work good?
Yes it worked well for what I was using it for.
I container for helping fat people loose weight...don't light the stove, just lock them inside for a few days. Charge by the pound lost? Could be a winner!
Had to stop watching. The starting and stopping and splicing is really annoying!!
When you make videos are you able to do it all in one take and not have to do any splicing? Thank you for the kind comment.
@@WilsonForestLands For many years I was very critical of people's video editing skills on TH-cam. Then I started making some. Good Lord...I appreciate the effort so much more now. Keep up the great work! I promise to ignore the annoying bits if you'll promise to do the same for me. heh
