Today, it was the day of slicing many concrete blocks to create the air
tunnel from the Earth Tubes Mixing Chamber to the house! The jigsaw puzzle
was very complex with a three dimensional aspect to it, both sloping
downwards, curving around and also widening out too!!
There was at least 17 cuts made, using a 9inch diamond disc in a high
powered angle grinder machine.

We need to go and buy two more concrete blocks to complete the “lid” to the
tunnel. That’s tomorrow’s job along with mortaring all the pieces together
into one smooth solid unit!
