repair porn - antique hand cranked hammer drill

My other half says this is his favourite from his repair-porn collection.

It shows a whole load of interesting techniques on a tool that many people will never have seen. Me included, I'll watch this after I've posted and trust him that it's as good as he says...

I remember rawlplug tools but they were just the bit like the bits for this but with a plain shank that you pounded on with a hammer.  Never seen one of these.
