How to Start a CNC Router Sign Business From Your Garage
A carved wood sign is a classic garage product: house numbers, family name boards, cabin signs and small business signs. A hobby CNC router does the cutting, but the business really comes down to design skills, consistent finishing and charging enough for your time.
What the Machine Costs
Hobby CNC routers span a wide range. As of October 2026, Carbide 3D lists the Shapeoko 4 from $1,800, the Shapeoko Pro from $2,400 and the Shapeoko 5 Pro from $2,980 (2×2 size) or $3,550. Onefinity lists its beginner Apprentice, with a 16.5” x 16.5” cutting area, at $995 on sale (normally $1,199). It also sells larger Elite machines in sizes up to 49” x 49”.
Match the size to the signs you plan to make. A small machine works for house numbers. A 24-inch family name board or a business sign needs a bigger bed, or you’ll have to tile the job in sections.
Software and Bits
You’ll need design (CAD) and toolpath (CAM) software. Carbide Create is free with Shapeoko and Nomad machines, and it handles text, V-carving and inlays. As of October 2026, OpenBuilds Part Store lists Vectric VCarve Desktop at $349, VCarve Pro at $699 and Aspire at $1,995. Vectric says Desktop handles jobs up to 24” x 24” without tiling. Easel is another beginner option.
Bits are an ongoing cost. Most sign work uses a few V-bits for lettering, a small end mill for detail, and a flattening bit to level boards.
Dust, Noise and Safety
- Dust: OSHA warns that airborne wood dust can cause respiratory problems and allergic reactions, and is linked to cancer. Use a dust shoe with a collector or shop vac and wear a respirator.
- Noise: NIOSH’s recommended limit is 85 dBA averaged over eight hours. Routers and shop vacs can be loud, so wear hearing protection and think about your neighbors.
- Spinning bits: Clamp the work securely, keep your hands out of the machine while it runs, never leave it running unattended and wear safety glasses.
- Finishes: Paints and outdoor sealers give off fumes, so ventilate well and follow the label.
What Sells and How to Price It
Personalized pieces are the core of the business: last-name signs, address plaques, wedding and housewarming gifts, and signs for local shops and farms. Outdoor signs need weather-resistant wood and a durable finish.
Build each price from materials, bit wear, finish, machine time and design time, plus a margin. Many makers charge separately for custom design work and keep fixed prices for standard templates. Avoid racing to the lowest price on marketplaces.
Skills to Learn and Mistakes to Avoid
- Learn vector design, font choice and feeds and speeds before you sell anything.
- Always test-cut new designs on scrap.
- Get a written spelling proof approved before cutting a custom name.
- Don’t buy the biggest machine first; start with the size your signs actually need.
- Don’t skip sealing outdoor signs.
Rules for home businesses, sales tax and insurance vary by state, county and city, so check locally or talk with a professional before you launch.
