‘‘Always do right. This will gratify some people and astonish the rest.’’
There are really large saws on excavators (about 40 ton if my memory serves me right) in a quarry near Helidon Qld. The amount of dust from cutting sand stone is unbelievable. They would need air con with good filters & i bet the engines have a series of prefilters as well. They use quite a lot of explosives there & a government controlled explosive store is nearby. Used to be the main store for australia in the 70's.
