Basic metalworking needs a stick welder (£50-150), angle grinder (£30-80), mask (£20-100), other safety gear (£20-100), assorted hand tools (£20-200) and a dry workspace with light, power and ventilation.

You can setup a simple workspace in any room with some basic protection for your fixtures and fittings. Or you can get popup workshop tents you can put in your garden.

You can get all your metal precut and drilled, even folded in a brake when you order it and get it delivered to save costs on drills and saws.

There's always lots of cheap tools and things around if you look at online listings locally especially since it skews older as a hobby so lots of house clearances selling good quality tools.

This is exactly how I started!
