Description
Cowboy CB3500 Compact Heavy-Duty Leather Sewing Machine
The Cowboy CB3500 is a compact, heavy-duty cylinder-bed leather sewing machine designed for professionals, leather artisans, repair shops, and serious hobbyists who need substantial sewing power in a space-saving machine.
The CB3500 combines a compound triple-feed walking foot, large-capacity bobbin, high presser-foot lift, and powerful low-speed servo motor to handle thick leather, webbing, synthetic materials, and other demanding applications.
Its 9-inch cylinder arm makes the CB3500 particularly useful for sewing three-dimensional, curved, and tubular products where a conventional flat-bed machine can be difficult to maneuver.
The CB3500 shares the major heavy-duty sewing capabilities of the larger Cowboy CB4500 while using a shorter cylinder arm. This makes it a practical choice for applications focused on smaller leather goods, tighter work areas, and compact workshop environments.
Key Features
Heavy-Duty Sewing Capacity
The CB3500 is designed to sew materials up to approximately 7/8 inch thick, depending on the material, thread, needle, and sewing conditions.
It can handle demanding materials such as:
- Saddle leather
- Heavy leather
- Nylon webbing
- Bioplastic
- Synthetic materials
- Multi-layer leather assemblies
Its strong needle penetration makes it suitable for applications requiring durable, structurally strong seams.
Compound Triple-Feed Walking Foot
The CB3500 features a compound triple-feed system, also known as a walking-foot feed mechanism.
The feed dog, walking foot, and needle work together to move the material through the machine.
This synchronized feeding system helps:
- Reduce shifting between layers
- Maintain consistent stitch length
- Improve material control
- Feed thick and difficult materials smoothly
- Handle multiple layers more effectively
This makes the CB3500 particularly suitable for heavy leather and layered materials.
Compact 9-Inch Cylinder Arm
The 9-inch cylinder arm is one of the defining features of the CB3500.
The compact cylinder-bed configuration makes it easier to sew three-dimensional and curved products, including:
- Holsters
- Knife sheaths
- Belts
- Bags
- Purses
- Saddles
- Harness components
- Shoe components
- Tubular leather goods
The shorter arm also provides excellent maneuverability when working on smaller products.
Large-Capacity Bobbin & Barrel Shuttle Hook
The CB3500 uses an extra-large bobbin and barrel shuttle hook, providing greater thread capacity than many standard sewing machines.
The increased bobbin capacity means fewer bobbin changes during longer sewing projects, helping reduce interruptions and improve workflow.
Heavy Thread Capability
The machine accommodates thread sizes from #69 through #415, making it suitable for applications requiring strong, highly visible stitching.
Heavy bonded nylon or polyester thread can be used for products such as:
- Holsters
- Harnesses
- Saddlery
- Heavy leather goods
- Belts
- Outdoor equipment
High Presser-Foot Lift
The presser foot can lift up to 1 1/16 inches, providing generous clearance for positioning thick and bulky materials beneath the needle.
This is especially useful when sewing multiple layers of leather or other heavy materials.
Low-Speed High-Torque Servo Motor
The CB3500 is equipped with a 750W/110V low-speed, high-torque servo motor.
The controlled low-speed operation allows the operator to sew carefully through corners, curves, tight areas, and detailed sections.
This level of speed control is particularly valuable for leatherworkers who need precise stitch placement rather than simply maximum sewing speed.
Versatile Attachment Options
The CB3500 can be configured with more than 20 available attachments, allowing the machine to adapt to different sewing requirements.
Depending on the application, available attachments can support work involving:
- Flat materials
- Harnesses
- Belts
- Bags
- Holsters
- Knife sheaths
- Wallets
- Purses
- Specialty leather goods
This gives the CB3500 considerable flexibility as your projects and production requirements change.
Compact Design for Smaller Workshops
The CB3500 uses a short 9-inch cylinder arm, making it more compact than longer-arm heavy-duty machines.
This design can be particularly beneficial for:
- Small leather workshops
- Independent leatherworkers
- Repair shops
- Home-based workshops
- Hobbyist workspaces
The compact configuration provides easier handling of smaller three-dimensional products while requiring less working space.
Applications
The Cowboy CB3500 is suitable for a wide variety of professional leather and heavy-material applications.

- Knife sheaths
- Belts
- Bags
- Purses
- Wallets

Precision in Tight Spaces
The CB3500’s shorter cylinder arm makes it particularly effective when working on smaller products that require precise stitching in confined areas.
The operator can maneuver products such as holsters, knife sheaths, belts, bags, and curved leather components around the cylinder arm while maintaining control over the sewing path.
Combined with the low-speed servo motor and compound-feed system, this makes the CB3500 well suited for detailed leatherwork where accuracy and material control are important.
