To make a clock out of gummy bears, I first used art resin to cast the gummies. For the base, I used a pink round mold. I dumped the gummies into the mold, allowing them to fall randomly.
Using equal parts of resin and hardener, I mixed up the epoxy; I used art resin. To ensure the epoxy was completely combined, I stirred for three minutes. If you recreate this follow the instructions for the specific resin you are using with precision.
Next, I poured the epoxy over the gummy bears and gave it a stir to coat the gummies on the bottom. I gave it a moment to sit, which allowed the air bubbles to rise to the surface and then popped the air bubbles with a torch.
After I let the gummies and epoxy sit for 24 hours until it completely hardened, I unloaded it from the mold.
Next, I used Adobe Illustrator to design a ring of plywood to perfectly fit the resin, and cut it on our Glowforge laser cutter. This would become an outer ring on the clock that the numbers would sit on.
After I got the ring to fit the resin, I used black acrylic to design and cut the numbers.
I ended up with an extra ring because I cut one too small. I decided to keep the smaller ring because it made a cool border and gave the piece a bit more dimension.
Next, I placed the gummy bears in the middle of the ring and with all the components ready, it was time for assembly.
First, I located the exact center of my resin disk. Next, I used a drill press and drilled through.
Using a combination of wood glue and CA glue, I separately glued my rings together. CA glue dries almost instantly and serves as a clamp to hold the wood glue tightly as it dries more slowly for the more secure bond.
I realized I needed one more laser cut disk to assist with assembly and laser cut a third circle with a smaller diameter to serve as a ledge for the resin block.
Once I stacked my three rings together, and had them glued, it was time to get the resin in place. To adhere the resin, I mixed up a five-minute two-part epoxy. Then, I heavily coated the ledge with the epoxy.
Next, I placed the gummy bear block. I added weight, and clamped it down to harden.
Once this was dried I used walnut oil as the final finish on the plywood. Usually, I wouldn’t oil something before gluing something else on top of it, but because this is a decorative piece and not something that was going to be taking a lot of wear and tear, it should be just fine.
Next, I used the same two-part five-minute epoxy to glue down the numbers. It was important to get these in the right spot; I started by positioning the 12, the 6, the 3, and the 9, ninety degrees away from one another. Then, I filled in the rest of the numbers.
Finally, I slid the clock on to the clock motor and installed the hands.
I was happy with the clock as the finished product, but this project could easily be taken a step further with some LED lights.
