Ah, the English Wheel. I used to work at Yorkshire Traction, and watched the bodymen using one of these on many occasions, turning a flat sheet into a complex compound curved panel with apparent ease. Then there were the coachpainters. A rep from a company selling spray painting equipment once came to demonstrate their new HVLP (high pressure low volume) sprayguns, promising a finish âat least as good as the one on that new busâŚâ Then he was told it wasnât new, just a repaint, so he asked what type of spraygun had been used. The paintshop foreman told the painter to fetch his âspraygunâ, and the painter brought three different brushes. The quality of the job was such that the salesman could not believe that the bus had been repainted by hand, and so no sale was forthcoming. We also had some very talented signwriters, carpenters, blacksmiths, fitters, upholsterers, electricians, mechanics, engineers and other skilled tradesmen. Then, along came Stagecoach and closed the Central Works, putting an end to over a century of skilled craftsmanship.

As a hopeless candidate who they tried to teach the black arts of sheet metalwork and fabrication such as gas welding sheet ally,or creating a wheeled master piece let alone using a planishing hammer to form curves,or just â â â â let alone vertical fillet arc welding.It was always going to be a very niche and extremely limited skill set then or now.Starting with a psychic like ability to see the flawless finished job in the piece of metal that youâre starting with and your brain to be two or more steps ahead of your hands at every stage of the process before it takes shape .

Not to mention being expected to calculate stuff like a bend allowance using the Zeus book tables if youâre lucky enough to have one in your pocket before youâve even been given the job to do.

As for the best brain numbing experience forget sheet metal.It was always hand scraping using a surface plate as part of the so called âengineering fittingâ discipline that did it for me.

All an accepted part of basic engineering training in the 70âs.
