Barry Bucknell!! That's a blast from the past! He's got a lot to answer for!
I used to work in a little retail timber yard in the 60s; no power, the only lighting was from Tilly lamps.
Anyway, BB had persuaded many people to panel their doors with hardboard, and they'd come in with their door sizes. We'd have stock sizes, 6'6" x 2'6", 6'8" x2'8", 6' x 2', etc, and they'd want the panel cut to size, meaning I'd have to sometimes take off just a few mms off that stock size. No power; all by hand.
Some people even came in with all four dimensions of the face of the door!
The only saving grace was the hardboard was Royalboard. I seem to recall it was the best available but can't find it these days. I used to unload 20 tons by hand every Monday morning, which, BTW, was not just for BB converts; the company supplied wholesale to DIY shops all over London.
