Introduction: A LEGO Bracelet

Picture of A LEGO Bracelet

In principle, a LEGO bracelet is simple - drill a hole in 6 bricks, and thread elastic and/or string through them all.

There are two ways of drilling the holes. The first method is to drill a hole in both the top and bottom of the brick, and thread the string over the small divider in the middle of the second. This is the most accurate, since you centrally align the hole on both sides. However, the threading is more complex.

The second method is to drill all the way through the brick, including the three connectors on the underside. This is less accurate, and more difficult to drill, since you must hold the drill perfectly vertical to ensure the exit wound is centrally positioned.

To expedite the process I took the second approach. To make the threading easy I used a 4mm drill which is large enough to thread the string without problems, but so large that it decimates the internal lug holes.

Step 1:

To protect the bricks I first trapped them between two flat bricks. This also allowed me to drill three holes in one vice operation.

Step 2:

I then wrappped a piece of paper around these flat bricks to soften grip of the vice. (In this case it happened to be an old magazine telling me I'd failed in my application for the London Marathon!)

Notice that the bricks are gripped slightly off-centre. This allows me to drill a hole in the centre brick without hitting the vice's support bar underneath.

Step 3:

Once you've drilled the holes, there will be a lot of plastic burrs. I use a small pointer, from a jewelers screwdriver set, to scrape this away. It's easy to put the pointer inside the lug holes and wiggle it around, as this clears enough stuff to make a clear the holes through the brick.

Step 4:

Thread a piece of string through the bricks. Each end of the string should be left half-way inside the bricks at the end. Make sure there's a small gap between each brick with exposed string; this is to allow it to flex while on the wrist.

Slowly drip glue into the brick, so that the string is fixed. I did this only on the two bricks at each end of the bracelet. And, as per the picture, don't close the loop!

I had tried threading elastic through the entire bracelet, but this caused it to hug the wrist too tightly. Being square plastic, this would leave marks if worn all day.

Step 5:

Take a short piece of elastic, poke it through the end two holes, and glue in place as you did with the string.

Step 6: Et Voila!

Simple, but care must be taken with the drill, especially if it's an electric power drill.

Note also that you can tighten and loosen the bracelet by fixing the bricks together on the back, as shown. Being LEGO, this can be adjusted time and time again, for different people. Especially handy for letting little sister borrow it!

They way you drilled them is so clever! Much easier and safer than holding them in your hand. :)
