So now we have the logs needed, they have to be put into place.
You may remember the ingredient list for the creation of the bridge, and that it doesn't include the word "Crane".
Some of you may see that as a problem, we see it as a challenge. As in "challenge accepted!"
This is how the ballet of the bulldozer and the tractor is completed:
Act 1.
The tractor is driven down across the creek, back up over the other side to the opposite bank.
The tractor operator then walks down and across the creek and back up the other side to the Dozer.
The Dozer pulls the logs into preparation place, in the correct order with the snig chain.
The drop to the water is about 2.3 metres.
Act 2.
The dozer using its blade, gently pushes the log across the void toward the opposite bank and waiting tractor, leaving a gap of about 1.5 metres.
The dozer operator then dismounts the dozer.
The operator then uses spare chain to create a loop around the end of the log - with the loose end about 3 m long.
Then he walks down across the creek, back up the bank to the tractor.
When on the other side, he hooks the snig chain up to the forks of the tractor - and throws the loose end toward the waiting log, and sometime assistant - who then links the two chains up.
Act 3.
The tractor operator lifts the forks of the dozer and reverses slowly.
The log is pulled gently and precicely into place.
A gentle applause is heard.
This ballet is performed at least 12 times.
