Garage machine shop for one-off parts and repairs

Local farms, auto and motorcycle restorers, hobbyist builders, inventors, small manufacturers and repair shops that need a part fast.

Hourly shop rate or a fixed quote per job, plus materials. Repeat work from a few local businesses matters more than one-off hobby jobs.

• Operating a lathe and mill
• Reading engineering drawings
• Precise measuring
• Quoting jobs accurately

• Zoning, home occupation permit and HOA or lease rules, since machine noise and metal chips may not be allowed at home
• General liability insurance, and check whether your homeowner's policy excludes business use
• Heavy machines need 3-phase or adequate single-phase power and a safe, level floor, so check this before buying
• Safety: guards, eye protection and no loose clothing around rotating tools
• Check how your state or city treats metal scrap, coolant and waste oil disposal
• Parts for aircraft, medical or safety-critical uses may need certifications, so be careful what you accept

Startup costs are typically around $6,000 to $25,000, depending on the lathe and mill you buy, whether they are used or new, your tooling, and your power setup. These are estimates, so check machine condition and power needs first.

Monthly revenue is typically around $1,000 to $5,000, depending on the jobs you take, your quoting accuracy, and local demand for repairs and prototypes. These are estimates of revenue, and the idea starts at about 10 hours a week.

Check zoning, home occupation permit, HOA or lease rules, since noise and metal chips may not be allowed. Also check whether your homeowner's policy excludes business use, scrap, coolant and waste oil disposal, and certification needs for safety-critical parts.
