Hi all,

I have hired a 3ton mechanical digger before, but with a new job at the
house I have to dig close and parallel to a wall. Is there a way of
angling the arm and digging in a kind of 45deg approach to the wall, or do
I need a special type of digger.

Just watch out for fibre-optic cables !

Yeah, only the copper ones are worth anything as scrap.

But just think of the fibre optic light sets you could make ...

Single-mode fibers don't work well.
The core is so narrow that you see little light from the end even
if the other is pointed at the sun
