hi it's time for great shorts and today it's time to unbox the dirty rocket stove made out of mud stay tuned welcome back subscribers if you haven't joined us yet you can do so by clicking on the green shorts icon that's going to appear in the bottom right hand corner of the screen throughout the video so it's been about two weeks since I originally cast the mud or cob rocket stove here in the bucket about a week ago like remove the firebox and hook out the chimney pipe and I did a little patching to the chimney for a few cavities that were there from the forming process thankfully my spare cob is still moist I'm going to use this to patch it up

I also use this opportunity to round over the connection between the firebox and the chimney that will make it less prone to breaking after all the repairs were made turn the rocket stove to face south I recovered and let it dry another week so now a week later let's get this out of the bucket first I'm going to prep my area by wrecking way two leaves and dry grass and leveling it with a flat shovel this step is important since we're in a drought and has it rained in a month or so next I'm going to put down two bricks to keep the mud rocket stove off the ground and a brick for the back now we'll unform the rocket stove

we'll carefully remove the last layer of paper revealing the cob I'm finding a few more cavities than I thought I would but those will easily be patched

this last layer of paper is going to peel off on its own as this dries out but I do need to remove it in the areas where I'm going to be patching and it's pretty easy to find the gaps just by pressing against the paper if you've got a detail-oriented kid like I do you can put them to work

I think what you get at that pin you should be able to see all the holes so in fact let's stop there and add the pot standoffs and fix the holes think it's stayed nice and moist you can for that this is actually really wet so not it's solidified a little bit since I made it but it's still nice and moist so we're going to grab a couple handfuls of this and go pack the holes but we want to make sure we don't cover up any paper all right so we need to be kind of detailed with that because we want the paper to eventually peel off which you'll do as it dries

where we got a bigger hole like this that's obviously got a gap in behind it as well let's go and push that gap in from the outside and I fill it in and then come back in with your table pressure put pressure on it to push it down in there it's good now fill that in

to get people off there kind of smooth it your thumbs that it blends with the other try not to pull it so much just

holy cow huh get it holy cow my goodness you're definitely a chip off the old block me cow before I at the pot standoffs which I want to use six inch bolts that I'm just going to push down into the cob I'm going to round off the top corner here a little bit of the chimney so these sharp edges that are going to be more prone to breaking off and cracking I'm just going to round that over and form it

once that's formed I'm going to push the bolts down I'm using three so I want them spaced at thirds I'm being careful here to avoid the armature and I'm pushing the cop in around the bolt to lock it in place this last one's a little bit longer so I got make sure it's even hit the armature there

I'm going to build a small fire in here and let it burn out fairly quickly just so we get a nice bed of coals then I'm going to block the front and let it bake

I am happy with this stove

now that they got a nice bed of coals in there I'm going to cover the opening of the firebox I did my firing in two stages starting with a small fire to warm the stove and then closing off the front and adding longer sticks to the inside creating a hotter fire but one that burns more slowly here you can see the pace of the drying with only about a half an inch of dry clay around the edge of the chimney

notice the drying is extended to almost a full inch you'll likely see some small surface cracks that form during the drying process while the clay is still soft you can close them up by pressing on them once the clay is dry they won't close up any further they would need to be patched all right there you have it folks drying the dirty rocket stove I'll do a fire in it about twice a week to continue with the drying process once this fire is cooled down I'm going to use this trash can lid as a sort of hat to protect this rocket stove on an ongoing basis whenever I'm not using it because it's raw or even if it is baked we're not truly firing it like you would fire ceramics so this would absorb water and break down over time so to make it last as long as possible I got to protect it with this hat let me know in the comments below if you've made this dirty rocket stove and if you have any questions as always our mission here at green shorts is to help you see green so you and save little green thanks for watching please like and share and subscribe for new DIY videos every

This is part 2 of my DIY Mud Rocket Stove project. Watch the making-of video:

Two weeks after the casting of the cob rocket stove, I take it out of its 5-gallon bucket form, patch a few holes with fresh cob and fire it up to dry it out. It will need another firing or two to complete the drying process. I'm please with the results of this rocket stove so far. It was designed to mimic my concrete rocket stove, with a more economical and environmentally friendly material...MUD! The concrete will last longer, but I like the performance of the cob stove.
