|The Blacksmith Shop: the guy in the red shirt is turning up the heat in |
this fire with a little hand driven air pump, getting blunt chisel tips red hot.
|The Anvil: when the chisels are hot enough they are worked |
with a hammer and handy ‘anvil’ to reestablish a good point.
|The Quarry Face: This guy is using a chisel to make small holes in the rock |
about 35mm in diameter and about 75mm deep and at about 250mm centres.
|The Machine: this guy is driving wedges down a line of holes (as created in the previous photo) to fracture this rock.|
|In the vertical rock face above you can see a line of wedge holes|
that have already been worked to fracture the rock. A line of holes
in the horizontal face contain wedges that were being driven.
|This is the result they are looking for – a nice clean, even fracture .|
|Finished Product: roughly dressed building blocks|
|Boys about Zeke’s age are hefting the finished blocks from the quarry down to the waterfront.|
|Here blocks are being stockpiled on the beach for shipment across to Nosy Be (by sailboat of course).|
|Some of the work crew badly wanted me to take this group shot – as you can see, they are pretty fit and healthy specimens.|
