Rocket Stove for my water heater

I have been heating our hot water in a "tanganyika boiler" for 20 years. Works great, keeps heat in but uses a bit of firewood. I want to cut down on the firewood so been planning on changing to rocket stove / wood gas. Wasn't sure about how a big size would work so we did a mock up. This is Erik Lokensgaard who is visiting and Dina my neighbors kid. Erik followed my directions and came up with this first attempt. You can see the flames under the pot.

More to come.....

Motivation and a new challenge

My buddy Matt Sevigny posted about his new project today.

Whenever Matt posts and mentions my blog there is a surge of hits to this blog. Today he mentioned my name enough times to make me uncomfortable. And the hits arent just a surge.

The other thing is that was what the doctor in me had ordered, some affirmation after a day in the office of hearing my weaknesses. I was searching around for a feel good fix. Thank you my friend. So that was today's motivation. (The person reminding me of weaknesses would say I am not solving anything, maybe not, but life is short.)

Now to Matt's blog post. Some of the ten readers will find this experience of his interesting if not informative. He is building a pizza oven, which is not such a big deal but as I told him,
I like:
-You are using soil!
-this is a progression, arches, vaults,domes, groins! then?
-You are using what you have lying around.
-It will be used to cook food, a useful piece of art.
-You are fulfilling a dream.
-You are excited
-You are gonna show the steps even if failure!

And the challenge? I also will build a pizza oven for home, finished by when my daughter returns in June 2013. Her coming home present, and hopefully a magnet to keep the kids close to home. This is not to compete with Matt, it is a personal challenge. I also will make the oven part out of clay/soil. I also will make with what is "local" meaning on my acreage or within 1 km as much as possible.

Widows Vault progress IV

As of yesterday there remained a 1 meter square section to finish.


It is remarkable how much pointing improves the look of a wall. Look at this wall and the next picture to see difference.

Odd how a picture sometimes makes you see something I did not notice in live time. That wide joint on the right at the level of the window arch. Too bad.


Note the hi- tech scaffolding. Dickson has scaffolding but I think because they can leave this in place they prefer this.
We had to revert back to plastering for fear of hairline separations on the vaults.

This is all that was left. So it means it takes about 4 weeks to do the roof part.

This was the previous week. I climbed up and noticed one hairline crack between two arches.
From this point on the groin pieces stop being perpendicular to the wall, and there is just arches. For each arch the springer brick needs to be cut so the first brick is wedged in.

Widows Vault progress

Dickson is doing great. I didnt have any thing to suggest on Wednesday . The 3rd and 4th pictures are from Sunday when I just happened by there. It is a classy job I must say. A pity to cover the bricks on top with cement plaster.
