|Bozwell and Tommy Dee size up the keystone|
The third and final week saw lot's of innovation and experimentation, the retaining wall for the berm was getting bigger, we used a bus tyre as a kind of a key stone to tie everything together at the flag wall junction and we used lots of hooping iron to tie our plating down onto the tyre courses below.
|Plywood backing blocks for extra strength|
For the first time (that I know of) we put thick plywood blocks inside the tyres before pounding and then we used 75mm bugle head screws to fix a hardwood plate to the outside of the tyres to make a really strong backing for book shelves or whatever you would want to hang on a wall.
These structures also worked extremely well for attaching the hooping iron to as well.

|Many hands make light work|
Ben and Sean worked on the greenhouse framing with a steady turnover of willing students plus a core group of people who were keen to learn about carpentry.
We sourced a load of used windows from the local tip shop along with a glass door with jamb and operable window in the top for less than $250.00 what a bargain!!

With all the plating on top of the tyre walls done and the bottle wall finally started it was time for the rain to fall.. and fall it did!
