Video Tutorial: DIY LED Epoxy Table

Also, there are several things which are difficult to fully explain with words and images, so be sure to check out the video tutorial below.

LED Table Introduction

So, I received a text from my friends at Riverside Lumber in New Orleans about some unique Sinker Cypress they received.  
I love working with Sinker Cypress because it is such a beautiful wood with lots of history. 
After spending an hour or so perusing the inventory, I purchased a Sinker Cypress slab (8′ x 1.5′ x 2″).

Also, the picture below is a picture of the wood after I cut it in half.
The Sinker Cypress sat in my shop for 3 months and I finally decided to use it to make an LED Epoxy Resin River Table.

Milling Sinker Cypress Wood

I normally start my woodworking projects with preparing the wood.
This LED table project was no different.  

First, I cut the 8 foot piece at 50″ long to form the length of the sinker cypress table.  
I used my straight edge and circular saw to make the cut for the resin table.
The LED river table will be 48″ long, but I left an extra inch on both ends to square the edges in a later step.

Straight Sides

The Sinker Cypress did not have a straight side to ride along the fence of the table saw.
As a result, I ripped it in half with my bandsaw.
A live edge slab, or any piece of wood without a straight side, cannot be cut with a table saw.

In order to cut any piece of wood on a table saw, it must have one straight side. Otherwise, it is not safe.

Then, I took the two pieces of sinker cypress and straightened out one side using my jointer jig with dovetail clamps.  
I really love this jointer jig because it really gets the sides very straight safely.

Removing Bark from Live Edge

First, I used a few of my general use chisels to remove the loose bark from each piece of sinker cypress. 
This cleans up the live edge sinker cypress.
Ultimately, I wanted to maintain the shape of the live edge, so I was careful during this process.

Flat Wood Surface

The sinker cypress was relatively flat as it was planed by my hardwood dealer.
However, I sent each piece through my planer a few times and removed 1/64″ on each pass.

Sanding Wood

Next, I sanded each piece of sinker cypress with my orbital sander.  
I sanded the faces, sides, and smoothed out the live edge where I removed the bark.  
Essentially, I started with 120 grit, 150 grit, and finally 220 grit.

Wood Sanding Tip:  For a very smooth finish, wipe down the wood with a damp cloth and sand again with your highest grit. The water lifts the grain a bit and helps remove the excess wood fibers.

Square Ends

First, I used my miter saw to square each end of the sinker cypress. 
Ultimately, it was only necessary to remove about 1/2″ from each side to get it square.  
This worked out because I may need to square it again at a later step and I would have 1″ remaining.  
Remember, I cut the piece at 50″.

Melamine Box

The melamine box helps prevent leaking during the epoxy resin pour.
Obviously, it is a very important step for the LED resin table.  

Epoxy resin doesn’t adhere to melamine, which makes melamine a perfect material to contain the epoxy resin. 
As a cheaper alternative to melamine, I use plywood covered with tuck tape.

Epoxy Resin Mold

I constructed the melamine box to the exact dimensions of the LED table.
This measurement includes the width of the epoxy river.

The bottom of the melamine box needed 2 pieces of melamine because I didn’t have a piece wide enough. 
So, I glued the 2 pieces together using spray adhesive with activator. 

Melamine Resin Mold for led river table

Essentially, this will create a strong enough adhesion to hold together.

The melamine box bottom was 20″ wide, 49″ long.  
I cut the sides at the same length as the bottom and they were 2 7/8″ high (wood is 2″ thick, melamine 3/4″ thick).
Next, I attached the sides with screws after drilling a pilot hole.

Mold assembly

I placed the sinker cypress pieces on the bottom and measured the ends to get an exact measurement.  
The ends were 21.5″ wide.

Quick Tip:  Tape measures are great, but use the board itself for a more accurate measurement.

Seal Melamine Box

First, I used my hot glue gun to seal the melamine box on the sides and corners for the LED Epoxy Resin River Table.

Next, I put a generous coat of Johnson Paste Wax on the bottom, sides, and top of box where the particle board was exposed.

Johnson Paste Wax serves as an epoxy release agent.
This makes it easy to remove the LED epoxy table.

Then, I placed the pieces of sinker cypress into the box and sealed around the edges and corners to prevent the epoxy resin from seeping out.

Seal Epoxy Mold with Hot Glue

I put down a thin piece of silicon caulk down the seam of the melamine box bottom.

Secure Wood to Mold

First, I used 6 blocks, 3 2x4s, and 6 f-clamps to hold the sinker cypress in place.  
This helps with minimizing the epoxy resin from seeping under the table as you can see in my video.

LED Table Epoxy Pour

Keep in mind, it is so important to follow the instructions when using epoxy resin.  
This stuff is not cheap and if you think you can skip an unimportant step – think again!
First, I mixed the epoxy resin at a 1:1 ratio (1 part hardener, 1 part resin) at a total of 16 ounces.

epoxy mix ratio

This amount is easy to handle.
When the material is first mixed (not whip b/c that causes bubbles) it will turn cloudy.

After a few minutes of mixing the material it will begin to ‘break’ and become easier to stir.
Also, the epoxy turns from cloudy to clear when fully mixed.

Epoxy Resin no bubbles

Then, I slowly poured the epoxy resin and covered the entire bottom about 1/4″ thick.

Finally, I used my heat gun to remove the bubbles.

Quick Tip:  Use a heat gun every 2 to 3 minutes for about 15 minutes to remove epoxy resin bubbles.

LED Epoxy Resin Pour

First, I removed the f-clamps, 2x4s, and 2×4 blocks from the LED Epoxy Resin River Table.
The epoxy holds the table in place, so there is no need to hold it in place.

Ultimately, the second pour repeated the same process as the first pour with the same amount of material (16 ounces total).

Embed LED Lights in Resin

Before proceeding to the next step in this LED epoxy table tutorial, I strongly recommend visiting my latest article on how to embed LED light strips in resin.

Ultimately, this procedure works much better than the procedure in this LED table tutorial.
It makes it easy to replace the LED strip in the future
If you decide to not use this procedure to embed led lights in epoxy, simply proceed to the next step.
I cover installing the LED lights using super glue in a later step.

Fire Glass in Epoxy Resin

For the third pour, I embedded blue rocks in the LED resin table.
I recommend to use acrylic rocks as I did on a recent epoxy river rock table project.

First, I poured the fire glass on top of the second layer of epoxy resin.
Also, I made sure the height of the fire glass was below the height of the resin table.

Next, I poured a layer of epoxy resin to cover the fire glass.

Finally, I used my heat gun to remove the bubbles.

Remove Epoxy Mould

The melamine box I used for the LED epoxy table mould released easily.

Obviously, it is a pain in the rear to prep the melamine box with wax, hot glue, etc., but it is very much worth the time.
I removed the sides, back/front, and then the bottom from the epoxy resin table.  
Unfortunately, I discovered epoxy resin leaked under the table.

Remove Excess Epoxy

First, I used my electric hand planer to remove 1/64″ of material on the underside of the LED table. 

It took quite a few passes to remove the excess. 
Also, I rarely use my electric hand planer because it makes a mess.
However, I’m glad I have one.

Next, I used my low angle jack plane to flatten out the bottom of the LED epoxy table.  
Keep in mind, I only used it on the wood – not the epoxy.

Finish Sanding

First, I sanded the LED table and epoxy resin very lightly with 220 grit sandpaper on the top and underside of the table.

Next, I used my stanley block plane to make sure one side was straight.

Then, I ran the LED table through my table saw while referencing the side I flattened with my hand plane.

Finally, I used my worx bench, straight edge, and circular saw to remove 1/2″ from each end.  This makes the table exactly 48″ wide.

Roundover Edges

I decided to use a 1/4″ roundover bit and my trim router to put a small roundover around the top of the LED Resin Table.  

It was perfect – I’m glad I didn’t use a 1/2″ roundover bit.

LED Table Underside

Since I planned to place LED lights under the epoxy table, I wanted the epoxy to be transparent.
In turn, I had to finish the underside of the epoxy river.

First, I decided to use HVAC tape to tape around the epoxy to prevent it from leaking on the wood.

Next, I mixed 6 ounces of epoxy resin and applied the final coat with a chip brush.
I didn’t have a foam brush at the time, so I used what I had in my shop.

Afterwards, I immediately removed the tape.

How To Fix Pinholes in Cured Epoxy

Somehow, I managed to miss these bubbles in epoxy resin after the initial pour.
No worries, I know how to remove bubbles in cured epoxy using a simple procedure.

First, I flipped the table over so the top side faced up.

I used my drill with a round countersink bit to gently bore out the bubbles.  
It worked like a charm.

Next, I mixed a very small amount of epoxy resin to fill the hole. I allowed this to cure.

Top Coat for Epoxy River Only

First of all, I hand sanded the surface of the LED river table with 1000 grit paper before I applied the final coat (hopefully, the true final coat this time).

Additionally, I also spent some time removing the debris from the hole I drilled.
Next, I repeated the process for the previous final cut.

However, I decided to test my painting ‘cut in’ skills by not using tape this time.

Actually, I ran out of HVAC tape so I didn’t have a choice.

Best Finish for Epoxy Wood Tables (UPDATED)

While the finish I used on this table worked fine, it is not the best.
In fact, I deleted the finish section in this LED resin table tutorial to give you better advice.
I wrote a detailed article summarizing the 4 best finishes for epoxy wood table tops.
Please read this article to learn how to finish epoxy wood tables and come back to this post.

Hairpin Legs

The hairpin legs are 28″ and they are sold in 2 colors – raw steel or black. 
Furthermore, I chose raw steel because it matches the style of table and the hardware in our house more than the black.
The quality of these hairpin legs shocked me because I did not expect them to be such solid legs.

First, I had to clean them using mineral spirits as they were full of residue.  
Presumably, the residue was put on them intentionally to prevent rust during shipment.
