Step 1: Creating a Box
Cut 5 pieces of wood: one (1) for the bottom, and four (4) for the sides, as shown.
Use screws or a hot glue gun to attach the wood together. You can make this as large or as small as you choose. I marked the perimeter of the box, to set a reference mark, so I know where to place the candles.
Step 2: Mixing the Concrete
Mix the concrete until it has a similar consistency to peanut butter. I used high strength concrete from Sakrete.
Pour the concrete in the box.
Tip: Oiling the wood first would make it release easier.
Step 3: Inserting the The Candles
Now, insert the quantity of candles you prefer; I only placed 4. I treat them as disposable because they are inexpensive. Click Here to see the candles I used.
I accidentally added too much water in my mix, so I sat it outside to allow the water to drain.
Step 4: Removing the Candles
About 30 to 40 minutes later, remove the candles. I used a piece of scrap plastic to clean out the hole and then widen it. This way, the hole was slightly larger than the candle to allow for easy insertion and removal.
I like the bubble holes in the form. If you do not prefer that look, then vibrate the concrete right after pouring it in the form (before it starts to cure). That should remove the majority of the bubbles.
I also removed the wood from the perimeter of the concrete, but not the bottom. This step can be skipped and removed later.
Step 5: Sanding
After 48 hours later the concrete is full cured.
I gave it a quick sand with a sanding block.
I then applied a concrete sealer, I used the sealer that looks wet when it is dried.
Step 6: Making the Wood Bottom
I cut 4 pieces of wood with miter comers.
On the long side, I used the lip of a bucket to assist me with the arch in the bottom. I then used a small can to assist on the short side.
I cut the curve out on the band saw. Then sanded it down on the belt sander. For the smaller piece, I used a hand sander.
Step 7: Assemble the Bottom
I used wood glue and a nail gun to join the bottom.
I applied a Mixwax stain with a brush and then wiped it off with a rag.
Step 8: Installing Bumpers
I installed rubber bumpers on the feet of the wooden bottom.
Step 9: Attaching the Wood to the Concrete
I mixed a two part Epoxy to secure the concrete to the wood.
I placed a weight to the concrete and gave it enough time to dry.
Step 10: Crossing the Finish Line
Insert the candles, and light it up!!
