Wow. That is a fantastic video on so many levels. Where to begin?
I definitely want one of those white dust coats with Colchester Lathe embroidered on the back.
And all that hand selecting of each and every headstock bearing roller? No wonder they cost mucho hundreds of pounds to buy replacement units.
And laying on the "bog" with six-inch spatulas to smooth out the castings. And hey look, they don't just clean the inside of the headstocks, they paint in there too!
Best part though is cleaning those casting mould boxes by spraying kerosene with a blow gun, then casually lighting a piece of paper from the (very) nearby blowtorch and flashing it all off. LOL. When men were men and WSH inspectors dared not leave Brussels and cross the Channel.
Great view of mid-century automated machining too. Some pretty fancy stuff there for its time.
