Re: Drilling rock for garden fountain??
Near here, in France, there is a stone mason that makes great fountains and sinks, etc, out of local limestone- about 55 mins from either Neuchâtel or Lausanne. Not os good for OP, but might come handy for someone in Romandie.
We will have a stone sink made when we do the new kitchen- as the original one was ripped out by the previous owners (the Protestant Church) in the 70s, together with the limestone floor and the wonderful tiled wood burner (grrrr). I found half an old stone sink in the garden- so will use it as the start of the waterfall going down to the pond when I get help with that- got plenty of limestone to clad the water stream down to the pond.
