This project is by Bob from I Like To Make Stuff. This DIY project not only showcases beautiful craftsmanship but also allows you to bring a piece of the beach into your home decor.
With a combination of concrete and epoxy resin, you can create a stunning table that resembles a cross-section of the ocean. Let’s dive into the step-by-step process of making this unique piece.
Step 1: Gather Your Materials
Before diving into the project, it’s important to gather all necessary materials and tools. Here’s what you will need:
- Heart pine slab for the legs
- Melamine for the concrete form
- Quickrete 5000 concrete mix
- Clear table top epoxy resin
- Nitrile gloves
- Plastic mixing buckets
- SawStop cabinet saw
- 8″ dado stack
- Dewalt 20v drill driver combo
- Evolution miter saw
- Countersink drill bits
- Orbital sander
- Shop Fox hanging air filter
- 2HP dust collector
- 1 micron bag
- Digital angle gauge
- Danish oil for finishing
Ensure you have safety gear like eye protection, ear protection, a respirator, and a first aid kit handy to make your project safe and enjoyable.
Step 2: Create the Concrete Form
The first step in this project is to create a mold for the concrete. Bob used melamine, which is ideal for this purpose as it prevents the concrete from sticking. Here’s how to build the form:
- Cut several pieces of melamine for the sides and a square piece for the bottom. The size should be suitable for a small end table.
- Screw the pieces together tightly to avoid any leaks during the pouring process.
- Make sure to cut smaller pieces of melamine to create inset spaces for the legs.
- Use CA glue to secure the corner pieces in place.
- Seal all seams and edges with silicone sealant to prevent concrete from leaking out.
Step 3: Mix and Pour the Concrete
Once the form is ready, it’s time to mix the concrete. Bob chose Quickrete 5000 for its durability. Follow these steps:
- In a mixing bucket, combine the Quickrete with water according to the instructions on the bag until you achieve the desired consistency.
- Lift one side of the form to create an angle that mimics a beach slope.
- Start pouring the concrete into the form, packing it down to eliminate air pockets.
- Shape the concrete to create a beach-like texture, with one side thinner and the other thicker.
- Use the orbital sander without the sanding pad to help remove air bubbles from the surface.
Step 4: Prepare the Legs
While the concrete cures, prepare the legs of the table. Bob used reclaimed heart pine for this part:
- Cut the heart pine to the desired leg size, ensuring to remove any rough edges.
- Sand the legs to remove dirt and imperfections.
- Cut additional pine strips to serve as cross braces between the legs.
Step 5: Pour the Epoxy Resin
After the concrete has cured for about 48 hours, it’s time to pour the epoxy resin. This stage requires precision:
- Clean any leftover concrete residue from the form to ensure a smooth finish.
- Mix the epoxy resin in a one-to-one ratio, following the manufacturer’s instructions closely.
- Add blue dye to the resin to achieve the ocean-like color, adjusting the amount to your preference.
- Pour the resin over the cured concrete, making sure it fills all corners and covers the surface completely.
- Use a heat gun to pop any air bubbles that rise to the surface.
Step 6: Final Layers and Curing
After the first layer of epoxy has cured, you may need to apply additional layers:
- After four hours, mix another batch of epoxy and pour it over the first layer.
- If cracks appear, carefully fill them with the new mixture and use the heat gun to remove any trapped air bubbles.
- Let the final layer cure for about two days to ensure it hardens properly.
Step 7: Removing the Form
Once the epoxy has fully cured, it’s time to remove the form:
- Unscrew the panels of the form carefully, starting with the sides.
- Be cautious with the corners as they may require some chiseling to free the epoxy.
- Use an orbital sander to smooth out the surfaces, being mindful to maintain clarity in the epoxy.
Step 8: Assemble the Legs
Now, it’s time to assemble the legs and attach them to the table:
- Create an X-shaped bracket with the cross braces for added stability.
- Use a crosscut sled to cut the necessary slots in the legs for the X braces.
- Glue and screw the legs into place, ensuring everything is aligned and square.
- Allow the glue to dry completely before moving on to the next step.
Step 9: Sanding and Finishing Touches
After the legs are secure, it’s time to finish the table:
- Sand all surfaces with progressively finer grits up to 1500 grit for a smooth finish.
- Use polishing compound to achieve a glossy surface on the epoxy.
- Apply Danish oil to the wood legs to enhance the grain and protect the wood.
Step 10: Final Assembly
Once everything is sanded and finished, it’s time to complete the assembly:
- Place the top piece onto the legs, ensuring it fits snugly.
- Since the weight of the top holds it in place, there’s no need for additional fasteners unless desired.
- Stand back and admire your ocean table, which is sure to be a conversation starter!
Conclusion
Creating this ocean table is not just a fulfilling project but also a beautiful addition to your home. Bob’s dedication to crafting this piece reflects the personal touch that DIY projects can bring. With some patience and creativity, you can replicate this project and bring a piece of the ocean into your living space. Whether for yourself or as a gift, this table is sure to impress.
