I still want a rocket stove!

I think that I have mentioned in two different threads that my sister announced that she was driving up today to camp in the backyard with her kids. I was excited to see them for the first time since Xistday in March when we met in a parking lot in Payson and shouted at each other.

I thought about how to fix up my office as a cabin and to make a fire pit, wondering what else would make a nice touch for campers.

Of course, Mom told my sister that I poisoned the lawn, so my sister canceled the trip. Allegedly they are coming up next weekend, but I will believe that when I see them.

I may hug them, too.

Not my sister. What has she ever done for me?!



I am not making a big fire pit with our available space, but a big rocket stove could easily replace the abomination pictured previously.

How hard is it to make a fire pit? You just build a circle of bricks or rocks, ideally with more bricks or rocks on the bottom.

I don't see why you couldn't leave a dirt bottom, but nobody does.

I wanted to make sure that I wasn't missing anything and I picked up some things:
  1. You want to line it with fire bricks because normal bricks won't last.
  2. You want a designated intake to make the smoke flow up, not in your face.
  3. Tractor Supply sells fire bricks!
I referred to real fire bricks and fake ones. I believe that one is light and reflects heat while the other is heavy [bricks are heavy?!] and simply withstands high heat. I am unsure which these are. Six or 10 for $33?

8.7?

The reviews just have useful stuff like "They are fire bricks, bricks I say, and can take a fire."

Like I wrote, useful.

They are 4.5 x 9 x 1.25. If I put two on the bottom, eight on the sides, and cut one in quarters for the corners, I could line this with 11 for $41.69 before tax.

One plan called for cutting bricks in half and using those for vents, so I guess that I will have a remainder.

Weird. I do not see the bricks that I have at Lowe's or Home Depot. They have to match!

Fun. The first one that it shows is 51, but says "3 in stock at nearby store
Apache Junction, 107.4 miles away."

I am not driving 214.8 miles for $1.53 in bricks!

Well, I am confident that they have bricks, and they are "4 x 8."

The old ones are 4"x8" and the new ones are 3.75 x 7.75.

I don't know what to do about the 1.25" gap besides make my own bricks. Bags of concrete are cheap and there are actually a few in the back of the shed, but I would only use 10% of one!

I think that it is curious that concrete molds are usually wood and plywood. Doesn't the wood pull moisture from the concrete?

I guess that is why you keep it moist. However, people make countertop molds out of melamine. I am sure that wood and plywood is fine, but I was thinking of transporting 4x8 sheets of not-plywood. I am sure that if you strap down plywood hard enough you will compress it, but not nearly as much as the not-plywood!

Materials:
  1. Fire bricks x 9 from Tractor Supply: $3.79 * 11 = $41.69
  2. Fourteen red bricks on the sides and six for the top. They are around 50 each * 20 = $10, but I should have enough.
  3. Furnace cement: $5 at Cal Ranch. Nobody else has it!
  4. I will use concrete as mortar. I am not buying a 50-pound bag for this small project!
  5. I am buying melamine for something else, but it is $29 for a 4x8 sheet.
  6. The aforementioned concrete [for the base].
