Introduction

The epoxy resin river table has become a symbol of modern woodworking. Its stunning blend of natural wood grain and vibrant epoxy colors captivates hobbyists and professionals alike. If you're a woodworking beginner, this might seem like a daunting project, but with the right tools, like a router sled, it’s totally achievable.

This blog is a complete guide to help you build your first epoxy resin river table, with a focus on using a router sled for flattening slabs. Whether you're new to woodworking or just new to epoxy, this project will help you level up your skills and create a centerpiece for any room.

Materials and Tools Needed

💡 Tip: Use a professional router sled like the SpeTool Cratos S01001 for smoother, easier slab flattening.

Step-by-Step: How to Make a River Table Using a Router Sled

Step 1: Choose and Prepare Your Wood

• Select two live-edge slabs with a pleasing grain pattern.

• Cut the inner edges straight with a circular saw or jointer.

• Arrange them so the natural edges face each other, forming the "river."

Step 2: Build the Mold

• Use melamine boards to create a tight, leak-proof mold.

• Seal all joints with silicone and apply tape or mold release.

• Place your slabs inside with the edges facing inward.

Step 3: Flatten the Slabs with a Router Sled

• Secure each slab to your workbench.

• Mount your router onto the router sled.

• Slide the router sled back and forth to remove high spots.

• Ensure both slabs are equally flat and level for a clean epoxy pour.

✅ Why use a router sled? It ensures your slabs are perfectly flat, avoiding uneven pours and sanding later.

Step 4: Mix and Pour the Epoxy

• Mix deep-pour epoxy resin per the manufacturer’s instructions.

• Add pigments or metallic powder to match your desired color.

• Slowly pour the resin between the slabs in layers.

• Use a heat gun to remove bubbles.

Step 5: Cure the Epoxy

• Let the epoxy cure for 2–5 days, depending on depth and temperature.

• Avoid moving or disturbing the mold during this time.

Step 6: Demold and Flatten the Whole Slab

• Remove the mold and inspect the surface.

• Flatten the entire tabletop again using your router sled.

• This step helps blend epoxy and wood surfaces into one smooth plane.

Step 7: Sand and Finish

• Sand the surface starting with 80 grit up to 400 or higher.

• Apply a finish like tung oil or polyurethane for protection and shine.

Step 8: Attach Legs or Base

• Choose a base (metal or wood) and attach it securely.

• Make sure the table is level before tightening.
