What it is

A small side business making replacement gaskets from sheet material using hand tools, a small bench cutter or a compact hobby cutting machine. For more complex or larger runs, you send files to a local laser or waterjet cutting service.

Your first three steps

  1. Pick a niche, such as vintage motorcycles or small outboard engines, and list the gasket sets owners often can't find
  2. Buy a starter set of sheet materials, punches and a cutting mat, and make test gaskets that you check against real parts
  3. Create listings on an online marketplace or simple website with clear photos, sizes and the materials used
Who pays

Classic car and motorcycle owners, small engine and equipment repair shops, boat owners, and hobbyist restorers, often through online marketplaces or your own simple website.

How it makes money

Sell individual gaskets or sets, priced by part and material, and charge a bit more for hard-to-find or custom shapes. Shipping is added per order.

Skills that help
  • Careful measuring and hand-cutting
  • Basic photo and listing skills for online selling
  • Patience with fiddly, detailed work
  • Clear customer communication about fit and materials
Watch out for
  • Check HOA, lease or home occupation rules before running a workshop from home
  • Product liability risk if a gasket fails, so ask an insurance agent about coverage and add clear fit and use notes
  • Avoid asbestos-containing material and check safety data sheets for what you cut
  • Check your state for sales tax registration and a local business license, and whether marketplaces collect tax for you
