Do you know what a Pump Drill is? I didn’t either, till I was introduced to one during my silversmithing class the other day. If I wasn’t yet quite under the spell of my new hobby, I certainly was after I’d met this unique and ingenious implement.
The first drills were really more like punches, which evolved to the hand twirling of a sharp object, leading to the first mechanical innovation in the field – the Strap Drill – thence to the far more efficient Bow Drill used by the Egyptians. The Pump Drill is a Roman innovation – the Romans were masters at improving on others’ inventions, so I shouldn’t be surprised to be using just such a tool today – though I was surprised at just how much it thrilled me!
