I remember having heard that chain was usually made in the back yards of individuals, lots of individuals in the Midlands. Today most people don't work at home as law, by-laws, insurance, health and safety, noise abatement and so on make it impossible. Indeed it's a wonder they allow us to engineer at home at all.
However if you move into an empty cattle shed somewhere and you manage to jump through all the hoops you might be able to earn a crust engineering wise. There again you'll perhaps find it cheaper and more profitable to subcontract the job to China.
I worked at a very small business back in the eighties (5 people) and we landed a contract with the M.O.D to make parts for guided missile launchers (Falklands war) and another for storage crates to hold spent uranium rods for the Nuclear industry!
If elf and safety get their way I think the next war will be fought with pillows by us Brits.
