Quoted price per part or per job, based on machine time, material and setup. Repeat small-batch work and quick-turnaround prototypes pay best.

• Machining on a mill and lathe
• Reading engineering drawings and tolerances
• Basic CAD/CAM or CNC programming
• Careful measuring and quality checking

• Zoning, noise and home-based business rules for a workshop at home, check with your municipality
• Commercial general liability insurance and cover for your equipment and premises
• Electrical supply, floor loading and fire safety in a garage, check with a qualified electrician
• Customers may expect inspection reports or certified materials, so know what you can honestly deliver

Estimates suggest startup costs are typically around $12,000 to $60,000, depending on the machines you buy, your tooling and your workshop setup. Inspect used machines before buying, as hidden wear can affect accuracy.

Estimated monthly revenue is typically around $1,500 to $7,500, depending on the jobs you win and the hours you work. The estimates assume at least about 10 hours a week.

Check zoning, noise and home-based business rules with your municipality, plus electrical supply, floor loading and fire safety with a qualified electrician. Also check commercial general liability and equipment insurance, and WCB/WSIB rules in your province if you hire help.
