Step-by-Step Router Sled Assembly Process
Step 1: Unbox and Organize Parts
Begin by carefully unpacking the parts and organizing them to ensure all components are easily accessible during assembly. This will make the process smoother and help avoid missing parts.

Step 2: Assemble the Wheels
Attach the 8 wheels to the slide platforms. Use M4*12 flat head screws and M4 lock nuts to secure each wheel in place. Be sure to stay consistent with each wheel assembly.

Step 3: Attach the Rails
Slide the M8 sliding nuts into the pre-drilled holes on the rails. These nuts will hold the platform securely in place. Place the lifts (left and right sections) onto the rails and align the holes with the sliding nuts. Adjust as needed.

Step 4: Secure the Platform
Use M8*14 combination screws to mount the slide platform onto the rails. Tighten the screws firmly to secure the platform. You can choose to mount the board either lengthwise or sideways, depending on your workspace and preferences.

Step 5: Attach the Knobs
Attach the M8*16 knobs to the lifts using flat washers. These knobs allow for easy height adjustment of the sled. Insert the fix knob into the wheel assembly to ensure the sled stays stable during use.

Step 6: Install the Router Plate
Slide the router plate into the rails. The plate comes pre-drilled for most routers, and there’s also a blank plate for custom DIY adjustments.
Mount your router and insert the router bit into the plate. Thanks to the SpeTool Cratos PRO router sled’s design, the router slides smoothly for precise adjustments.
Step 7: Fine-Tune the Height Adjustment
The SpeTool Cratos PRO router sled has 5 pre-set Z-axis positions. This lets you adjust the sled’s height easily and accurately. Whether working with thin or thick materials (ranging from 3/4 inch to 6 inches), simply select the height that works best for your project.
Step 8: Secure the Wood Plate
Use the provided clamping tools to secure your wood slab to the sled. This keeps the wood in place during the flattening process, helping things run smoothly and steadily.
Step 9: Test the Setup
With everything assembled, test your sled. Adjust the height, insert your router bit, and begin flattening your wood slabs. The SpeTool Cratos PRO router sled gives you smooth and accurate results. It features sturdy aluminum rails and easy-to-use adjustment options.
