Baileigh MPS-3 Throatless Rotary Shear
The Baileigh MPS-3 is a manual throatless rotary shear designed to cut smooth, flowing curves and straight lines in sheet metal up to 2mm thick. Perfect for fabrication shops, schools, and hobbyists who need precision cutting without the limitations of traditional shears.
Ever wondered how professional fabrication shops achieve those perfect flowing curves in their metalwork? The answer is the Baileigh MPS-3 throatless rotary shear, and it's now within reach for your workshop. This versatile tool transforms how you work with sheet metal, giving you the freedom to cut in any direction you need.
What makes the MPS-3 special is its unique rotary blade design. Unlike conventional shears that force you to work around throat depth limitations, this throatless design lets material pass completely through the machine. You'll never feel restricted when working with large panels or creating intricate patterns. The two rotating blades only engage at their closest point, which means you can smoothly turn and manipulate your material in any direction while maintaining complete control over your cuts.
Built with a heavy duty cast iron body, this shear is engineered for years of reliable service in demanding shop environments. Whether you're a small fabrication shop handling custom projects, an educational institution teaching metalworking skills, or a serious hobbyist crafting automotive parts or architectural details, the MPS-3 delivers professional results every time. The adjustable blade system accommodates different material thicknesses, while the integrated ratcheting mechanism gives you precise control over each cut. An adjustable backstop ensures repeatability when you need multiple identical pieces.

Applications
- Automotive restoration projects: Create custom body panels, trim pieces, and curved fender sections with precision
- HVAC ductwork fabrication: Cut complex shapes and curves for custom duct transitions and fittings
- Architectural metalwork: Produce decorative panels, curved trim, and artistic metal features for interior and exterior applications
- Sign making and lettering: Cut intricate shapes and curves for metal signage and dimensional letters
- Educational workshops: Teach students proper sheet metal cutting techniques with a safe, easy-to-use tool
- Prototype development: Quickly create test pieces and sample parts without investing in expensive dies or tooling
Key Features & Benefits
- Throatless design for unlimited material size: Work with large panels without worrying about throat depth restrictions. This means you can tackle bigger projects and create larger pieces without constantly repositioning your material.
- Dual rotating blade system: The innovative blade configuration only shears where the blades meet, allowing you to cut in any direction. This gives you the creative freedom to follow complex patterns and create smooth, flowing curves that would be impossible with traditional shears.
- Ratcheting control mechanism: Take complete command of your cutting speed and pressure. The ratchet lets you make controlled, incremental cuts, which is especially helpful when working through thicker materials or creating detailed patterns.
- Cast iron construction for durability: Built to withstand the rigors of daily shop use, the solid cast iron body absorbs vibration and maintains accuracy year after year. You're investing in a tool that will serve your workshop for decades.
- Adjustable blade clearance: Easily accommodate different material thicknesses from thin gauges up to 2mm mild steel. You won't need multiple tools for different projects.
- Fully adjustable material guides: Keep your cuts accurate and consistent with precision guides that help you maintain straight lines or controlled curves. This feature significantly reduces scrap and rework.
- Adjustable backstop for repeatability: When you need to produce multiple identical pieces, the backstop ensures every cut is exactly the same. This saves you time and materials on production runs.
- Manual operation requires no power: Work anywhere in your shop without worrying about electrical outlets or cords. The manual design also gives you better tactile feedback and control compared to powered alternatives.

Frequently Asked Questions
What thickness of material can the MPS3 cut?
The MPS-3 can handle mild steel up to 2mm thick (14 gauge). For softer materials like aluminum, you may be able to cut slightly thicker gauges. The adjustable blade clearance lets you optimize cutting performance for different material types and thicknesses.
Do I need electricity to operate this shear?
No, the MPS-3 is completely manual. This means you can position it anywhere in your workshop without worrying about power outlets. The ratcheting mechanism provides excellent leverage, making it surprisingly easy to cut through metal without electrical assistance.
How do I maintain the blades, and when should they be replaced?
Keep the blades clean and occasionally apply a light machine oil to the moving parts. Blade life depends on usage and material types, but you'll know it's time to replace them when you notice rough edges on your cuts or increased effort required to shear. The adjustable blade clearance can extend blade life by allowing you to compensate for minor wear.
Can I cut curves and circles with this shear?
Absolutely! That's one of the MPS-3's strongest features. The throatless design and rotating blade system allow you to turn your material in any direction while cutting, making it ideal for creating smooth curves, circles, and complex shapes that would be difficult or impossible with traditional straight-blade shears.
What's the difference between this and a traditional bench shear?
Traditional bench shears have a fixed throat depth that limits the size of material you can work with and typically only cut straight lines. The MPS-3's throatless design eliminates size restrictions and allows you to cut curves, circles, and complex patterns. Think of it as the difference between scissors and a craft knife – both cut, but one gives you far more creative freedom.
