Step 1: Creating a Box
Cut 5 piece of wood 1 for the bottom and 4 for the sides as shown.
Use a hot glue gun or screws to attach the wood together. You can make this as large or small as you like. I marked the perimeter of the box, to set a reference marks so I know where to place the candles.
Step 2: Mixing the Concrete
Mix the concrete to a peanut butter mix. I used high strength concrete from Sakrete
Pour the concrete in the box. Other viewers gave me a tip that oiling the wood first would make it release much easier.
Step 3: Inserting the The Candles
Now insert the quantity of candles you like, I only placed 4 of them. I treat them as disposable they are rather cheap. Click Here for the candles I used.
I added too much water in my mix by accident so I sat it outside so the water could drain.
Step 4: Removing the Candles
About 30 to 40 min later the remove the candles. I use a piece of scarp plastic to clean out the hole and widen it a bit. This way the hole is slightly larger that the candle for easy inserting and removal.
I like the bubble holes in the form. If you don't like that look, then vibrate the concrete right after pouring it in the form; before it start to cure. That should remove the majority of the bobbles.
I also remove the wood from the perimeter of the concrete, but not the bottom. This step can be skipped and removed later.
Step 5: Sanding
48 hours later the concrete is full cured.
I gave it a quick sand with a sanding block.
Then applied a concrete sealer, I got the sealer the looks wet when its dried.
Step 6: Making the Wood Bottom
I cut 4 piece 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. Then a small can to assist on the short side.
I cut the curve out on the band saw. Then sand 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 then wiped it off with a rag.
Step 9: Attaching the Wood to the Concrete
I mixed a 2 part Epoxy to secure the concrete to the wood.
I place weight to the concrete and gave it enough time to dry.
Step 10: Crossing the Finish Line
Insert the candles light it up and your done!
