What it is

A compact home workshop with a benchtop mill, lathe or small CNC that produces one-off parts, prototypes and replacements for older machinery, often for small customers.

Your first three steps

  1. Take a community college or makerspace machining class if you need practice, and make sample parts for your portfolio
  2. Check zoning, HOA or lease rules and your power capacity before buying a benchtop machine
  3. Show your samples to local repair shops and list your services on local classifieds and machining forums
Who pays

Farm and equipment repair shops, hobby and vintage machinery owners, small manufacturers and local makers needing a few parts at a time.

How it makes money

Fixed price per part or hourly shop rate plus materials, with a minimum charge to cover setup time on small orders.
