Solid rock meets metal

Do you remember the trouble we had levelling the far end of the front section to place the tyres? Well, we're back to that big 'ole piece of solid granite. This time we're trying to bash the rebar into it. One things for sure, once it's in it ain't going nowhere!

Dave wanted to try out his idea of using rebar at a 45 degree angle cutting down on the use of cement (the books detail using bolts set in concrete in every other tyre). We're putting in two pieces of 80cm lengths of rebar into every other tyre - see diagram below. The main trick we learnt today was to pin the pieces of wood together temporarily so they don't slip apart when bashing in the rebar.
