steel centre post and horizontal support beam

 This picture shows the horizontal support beam being levered up into position. Note the slots in the top layer of bricks, there are two of these built into to the top layer of brick work, at opposite sides of the building. 

These slots will house each end of the horizontal support beam which will be secured in place with mud. Extra stability is given by a centre post (see next photo).

 Note that the beam has two bits sticking out the top half way along..the beam will be turned over when it's in place and those bits will point downwards to connect to the centre post.






A hole was dug in the centre of the main fire bunker room and the centre post roughly installed. It still needs to be lined up properly with the horizontal support beam above it.

The centre post has been constructed with its own stablising peg at the base, which will allow it to be embedded into cement.












After the centre post (vertical) is properly attached to the horizontal support beam (with those braces noted earlier) it is ready to have it's base cemented in place.
