Another welcome here.
I’m not a machinist – more Physics and Chemistry with a bit of maths thrown in – but have had a varied working life.
DBS is still current but I’m not sure if I will use it much now. Grandson, who is now 9, is looking like a promising apprentice for my workshop in the near future.
The country most certainly needs manufacturing industry not just service industries, so go for it. Just remember that engineering has a whole load of prefixes – not just ‘mechanical’.
