Sloson Router Sled for Flattening Slabs – 48-Inch, Height Adjustable, Heavy-Duty Steel Rails

Overview

The Sloson Router Sled is a purpose-built jig designed to help you flatten slabs and other workpieces right in your own shop. At 48 inches, it provides a substantial travel path while staying affordable compared to a CNC machine. The result is better control, predictable planing passes, and the flexibility to tackle projects as they come.

Key benefits

• No CNC required—this sled brings precision and repeatability to everyday woodworking.
• Heavy-duty steel rails resist bending for steadier passes and truer thicknesses.
• Height adjustable with two L-Carriages and a sliding block for accurate depth in XY directions.
• Z-axis presets let you set consistent router heights across different slabs.
• Compatible with most fixed-base routers; acrylic support plate allows easy mounting and customization.
• Versatile for surface milling, live-edge slabs, butcher blocks, or building a sturdy workbench.

Design and setup

The sled combines steel rails with aluminum components, creating a robust yet adaptable platform. The dual L-Carriages glide smoothly along the rails, while the adjustable block positions the router at your chosen height. The included acrylic plate supports hole patterns and router alignment, making installation practical for a range of router bases.

Practical use cases

• Flatten finishes and smooth uneven surfaces on boards without a CNC.
• Prepare live-edge slabs for countertops or tabletops with consistent thickness.
• Butcher blocks, workbenches, or other flat surfaces that benefit from controlled planing.

Compatibility and care

The sled is designed to fit a broad spectrum of fixed-base routers. Keep rails clean and check alignment after heavy use to maintain consistent results across sessions. With regular checks, you can rely on stable performance across multiple slabs and projects.

What you get

In a single kit you gain the foundational sled, the two L-Carriages, an adjustable sliding block, and the Z-axis preset positions. Use with your existing router and start planning surfaces that suit your shop workflow. Router not included.
