Here's some pix of the process. In all we took down 5 blackbutts (great for building, but not good for sticking in the ground and so no good for fence posts) and a terpentine (which Phil cut up into some 40 split posts and still there is a few cubic meters of timber left for milling).
One of the pix below shows the pile of 'firewood' at a very early stage. Silly me forgot to take more pix, but it ended up to be at least 5 times as big and took 4 days to burn down to ash.
Another just shows what the inside of some of the blackbutts was like - ants had got to them and although they were up to 150-odd years old, it was an unscheduled accident waiting to happen.
We're planning to put a big 3-bay shed in the area where the tress once stood - of course, we'll have to somehow get those stumps out first ...
