Many decades ago, I was teaching in a jewellery workshop. I glanced around and saw these two unusual machines. I quickly got my camera and photographed them. THIS IS THE FIRST TIME THAT THEY ARE BEING SEEN IN PUBLIC.
Would you believe that these are the beginnings of 'bench-grinding machines'?
I, for one, wouldn't let my gravers get anywhere near them. The weight of either of them is beyond my calculations. This very heavy rotating stone could weigh hundreds of pounds. Just look at the wooden support that holds the grinding wheel. AMAZING!
