What it is
A small-scale version using a bench lathe, mill or small CNC machine in a garage or outbuilding. You make one-off parts, repairs and prototypes to customer drawings.
Your first three steps
- Check your lease, mortgage terms and local council rules on running a workshop from home, including noise
- Choose a narrow niche, such as classic car parts or prototype brackets, and set a rate per hour
- Show examples of your work online and approach local makerspaces, designers and repair shops for small jobs
Who pays
Inventors, hobbyists, classic vehicle and model engineering owners, start-ups needing prototypes and local firms with small urgent jobs.
How it makes money
Fixed price per part or hourly machining rate, plus materials. Small jobs and repairs suit limited hours.
Skills that help
- Machining on lathes and mills
- Reading drawings and working to tolerance
- Measuring and inspection
- Clear communication on what is achievable
Watch out for

- Noise, swarf and neighbour complaints
- Public liability and home insurance may not cover business machinery, so check with your insurer
- Machine guarding, safe electrics and personal safety such as eye protection
- Liability if a part you make fails, so be clear about what you will and will not machine
