Rocket Stove / Pizza Oven Part Three



Mario (me, the boss) worked the cement mixer, feverishly mixing concrete, while Luigi, the worker, danced with the wheelbarrow, filling the form. 

With the foundation complete, next up was the framework.
Pressure treated lumber consisting of 4x4's and 2x6's were used to build the frame.  Concrete fasteners  secured the structure  to the foundation with stainless steel brackets.
This framework needed Mario again.  Back to the mixer I slaved, while Luigi danced his way through a little bit of wheelbarrow opera!   Here's the recipe for the concrete mix we used.... here.  
Building the form for the "countertop and base of oven" pour.

More welding with Mr. FT!

Two ammonites were secured to the front of the form.

Form  joints are siliconed, metal reinforcement is added and ready for the pour.

Concrete sits to cure.  Tarps covered this for a few days and it was sprayed with water at least four times.

Just as you thought you were going to see something cooking, here I am to bore you with all the technical difficulties.  Next up we watch Mr. FT do his thing, and I am here to tell you his story with crappy pictures.  Sorry. 
Holes were cut into the top of the keg for  flame to escape.  Luckily we had this stainless steel pan salvaged from a few years back.  Can you believe it was within inches of the size we needed.  How lucky was that?  Mr FT used a zip-cut disk, cut a circle, and fitted the pan to sit  on top of some flanges that he welded  to the sides of the keg. 


Rocket stove is fitted into the structure, levelled and secured with a few welds.


Stainless steel is added to the top of the pan.

All done.

A top plate of upside down 5/16 checker plate was used as a cooking surface.  The video below shows us already putting it to use.  Egg pizza!


A chimney is built using an old Corny keg.   The chimney cap (not shown) was the top of an old Sanke keg.  He was the ultimate recycler using every part of the keg! 


Building the damper for the chimney!

Two days of rock and brick begin...








A special refractory mix was used to glue the rocks and bricks together.
