Hi Matt,
I absolutely LOVE your rocketstoves... and I love the fact that you share all of your knowledge with others, through pictures and videos. You've inspired me to want to build a few for myself now, but the one for the house will have to wait, due to strict fire regulations here in Germany, but the first one for the patio has been started, no codes yet for having one outside! Hurray!
I used these rock blocks, not sure what they are called in english but translated, they would be called "chimney blocks", its where the inner core of the chimney would go through, if you were building a conventional chimney. They are hollow, so I was wondering if I can use them for the mass. Does the size of the hot air ducts matter?
I used the measurements for the core taken from the book so the heatriser is 7x7 inches, same as the feed tube. Burn tunnel is half the size of the heatriser.
Unfortunately, I'm not able to find photos or a video, on how to connect, or how to make a nice exit from the bottom of the barrel to the part that will 1) flow into the mass, and 2)will have a clean out hole.
One has to understand, that things are much more regulated and controlled here. They more or less force you to buy new and expensive material and parts. I've seen the smaller stores close down, to make way for the huge DYI chains, and even there you won't be able to find certain objects, so you have to go to a special shop, and that's where it gets ridiculously expensive. I've seen cardboard, chicken-wire or even a sheet of thin metal to form connections, and then "cob" it in, and smooth it out. I figured that's how I was gonna have to proceed, and will probably need a t-shaped pipe that I will most likely have to buy, but maybe I could make it comepletely on my own, using y-tong stones... now as I type, this idea is coming to my head...
Please let me know, if the chimney blocks I'm using for the mass, if the tunnel would be too large, or if I should proceed differently for the mass... I hope I haven't confused you. I would appreciate any input...
Here are some fotos of what I've accomplished so far..... hmmm, how do I load them up here?
