14. Rumbling

 

Tim bought an old cement mixer in 2012, and it is now used to rumble our cropped granite setts until their sharp edges are beaten off in the rotating drum. The setts are thrown into the rotating drum and left to bash about inside for about ten minutes, before the rotation direction is reversed and the setts are unceremoniously deposited on the ground. The noise of the granite bashing around inside the drum is quite astonishing, reverberating around the whole quarry.

What struck me about this was how the cement mixer had been coopted into a task it was not designed to undertake. The drum has gradually been deformed by the granite smashing against the inner steel plating. This is a classic instance of using the wrong tool for a job, with very successful results — the aged setts are very popular.
