I have wanted to try experimenting with rocket stoves for a long time now. So I finally scrounged enough material for a pocket rocket. This is a welcome tool for my worksite as it is a great hand warmer for those chilly days. I know I used galvanized pipe, which is wrong. Supposedly, the galvanized material on the pipe will off-gas mustard gas. I'm not sure of the specifics but it is meant for ducting forced air in a house and not for heating. When I find some proper pipe I'll change it over. Here is the source instructions: rocketstoves.com/excerpts.htmHere are my pictures: picasaweb.google.com/4bakerz/ProjectPocketRocketCheers, Billy |

This worked great, but I didn't seem to be getting the rocket effect I desired. So I trimmed off 3/4" of the bottom of the feed tube. It now rockets quite well, maybe a bit to well, as I don't seem to be getting much heat radiating back up the feed tube.
Originally, I'd say there was an inch at most of space at the bottom of the feed tube. Now there is about 1 3/4" - 2".
This is a nice device for the workksite, it burns very little scrap wood and is a source of heat.
Lovely,
Billy

Good stuff!
You will notice that ash will eventually pile up at the bottom of the feed tube, slowing down the burn.. Just tip the whole thing on it's side to scoot the ash out of the way before you start it each time. Sooner or later you'll need to clear it out completely.
With the feed tube set properly there should be little to no heat coming out of the feed tube at all.. Remember, it is drawing cool air down that tube, if you are getting much heat out of there, something is wrong.
Pocket rockets are great little heat producers..
Although they have some features in common, I think that they aren't really "Rocket Stoves"..
Anyone know why I would say such a thing?

There are some really good conversations on here and I hope to share some more shortly. All keep up the GREAT work and testing!

Wow, you asked that question a really long time ago... lol
They aren't rocket stoves because they don't have the insulated rocket tube to complete the combustion?

Basically, yeah..
The stovepipe is outside of the stove, rather than inside it.
It's a blastin' cool stove, just not what I consider to be a "Rocket Stove"..

One one of the pictures, you show little white wisps. Galv pipe doesn't produce mustard gas (who told you that? Smack 'em for me) It does produce chafed zinc....actually zinc oxide usually. Eitherway, it'll give you "zinc shakes" as the metal screws with ....either neurotransmitter function or ion transport through cell membranes...can't remember which...maybe neither. Either way, not good. Can range from mildly sick to dead, with most of it being on the violently miserably ill. Don't breathe it, don't cook in galv, don't weld on it, etc. Be sane, it'll all be ok. Or use SS, and it'll be better  |
