I've finally started on my rocket stove! It's been a process getting all the parts together. I've got everything I need outside of some pumice and warm weather for cob. I posted some pictures of the project and will continue to as I go.
Let me know if you have any feedback. Thanks, Michael
Mmmm.. That is one well made rocket stove! The only things I can say is: 1) you will need to remove the earthbags (holding up the pipe) close to the stove. when it gets used for real, the bags will melt. 2) That's a long run of pipe there.. It looks likely to work just fine. Though on those odd days when the stove doesn't want to light cleanly, the primer box is pretty far from where the action is. Actually, on second thought I don't see a primer box inside the building. So you will have to go outside to deal with it.. Or just subbornly battle an obstinate stove till it finally gives in.
oop!! On third thought, I see that a primer box won't help you one bit... Cool idea, putting the exhaust out the side like that. Kinda like a direct vent heater jobbie.. There is some use of a chimney, even a short one. Priming for one, also taking the little bit of smoke overhead and out of harms way... Easy enough to retrofit if needed.. You gotta update us here as you use it.
During the test burn #1 there were all kinds of problems with the stove. Smoke back-drafting, hard to light, a very windy day. Problems ( besides being put together haphazardly ) The space between the heat riser and the barrel was too short - 1 1/2". I made it 2 1/2". Also the top of the heat-riser was not level and a bit bumpy - creating drag. The exhaust pipe straight out the wall worked, ok, but since then I've added a T for clean out and priming and 4' of pipe for the vertical stack. I also insulated the hell out of it with pumice, which may or may not have made a difference.
After the modifications it purred. Lighting quickly. It seems very happy now. We'll see how it goes when the wind kicks up again, but it's better prepared this time.
Ya - going out side to prime is lame. Makes me think I should place another T in by the exterior wall for inside priming. I've also fantasized about a propane torch for priming, but that's another story.
Last night we really gave it a good solid burn. Boiled water for pasta, chicken soup and vegetables in a tinfoil wrap. I am so pleased. When is somebody going to write the rocket stove cookbook anyway?
I have some more pics to post. I'll get them up as soon as possible. I can't wait to start cobbing on the bench, but there are a few more things I'd like to do before then.

briank: Thanks Daryl and Eric. The rocket bug has been in the back of my mind a lot lately. Thought I'd do some catching up here on the latest and greatest developments. I'm really liking the half barrel bell idea Matt came up with a couple years ago.

ericvw: Staying warm, Daryl?

Daryl: I remembered why I hate winter. Oil is at an all time low so I am good.

keithturtle: How long will it stay low?

wolf1004: Oil will stay low for a while, the bigger question is how long will we have jobs so we have the money to buy it? Low or not?

Daryl: Keith, prices are supposed to continue to go down. Wolf, I could lose my job today. No biggie. I'm taking life as it comes.

Daryl: Hey, Eric. What is up!!! How does it go down there in VA? Got a dusting of snow last night. Too cold to go hiking but we did catch some football this weekend.

Daryl: Oh, and one more thing, Eric...about a year with the guitar! I am happy that I reached that anniversary.

Daryl: I meant that I can handle what comes my way. I don't care. Lol. I will survive. I may have my job for the rest of my life or lose it tomorrow. You never know. But I am cool with it.

janmetal: Fireproof stones.. Can they be made DIY or do I have to buy? - Simple Nepalese design wanted.

ericvw: Looks like you've had some time to reflect, Daryl. We got about 14" snow this past weekend. It is melting away nice and quick.
Jan 27, 2016 20:46:59 GMT -8
Daryl: No more snow, Eric! Keep it! Supposed to be close to 50 the next couple of days.
