What it is
A small bench-based workshop that repairs, recalibrates and certifies compact scales such as counter, postal, kitchen, jewelry and lab balances. Customers drop them off or send them by mail, and you can add occasional site visits for larger scales.

- Set up a bench with test weights, tools and a stock of common load cells and parts, and practice on second-hand scales
- Create a simple website and local listing, then contact nearby cafes, jewelers and online sellers to offer calibration
Who pays
Small shops, cafes and bakeries, jewelers, online sellers, small labs, clinics and hobby or craft businesses.
How it makes money
A flat fee per scale for repair and calibration, plus parts. Some shops sign up for yearly checks of several scales.
