What it is

A small workshop in a garage or outbuilding, using manual or basic machines to make single replacement parts such as shafts, bushes and brackets when the original is worn out or no longer sold.

Your first three steps

  1. Find a secure, well-powered space and price up a used lathe, mill, tooling and measuring tools
  2. Make a few sample parts and photograph them for a simple portfolio or web page
  3. Introduce yourself to local repair firms, farm engineers and maintenance managers and offer a quick turnaround on one-off jobs
Who pays

Local farms, small factories, workshops, machinery repairers and hobby or vintage machinery owners.

How it makes money

You charge per job, based on your hourly rate, materials and any setup. Word of mouth from repairers and maintenance staff brings repeat work.
