If you have a spare bike chain or just want to be a cool biker, why not have a tight looking bracelet? This is how you make a breacelet out of a bike chain. It can be as tight or loose as you want (I chose to have it skin tight). I haven't had the time to fit a snap onto the bracelet, so once it is on, it's stuck until you get a chance to use your bike tool again. Have fun!

Step 1: Materials and Tools

Here is a list of all the things you need to make this bracelet:

Materials:
Bicycle chain
Old rag
Degreaser (You can use a professional degreasing product, but rubbing alcohol works just as well. Watered down dish soap also works.)
Cup or tub (for degreaser)

Tools:
Bicycle chain breaker tool

You don't have to watch the whole thing but it will help.

Step 2: Mix and Degrease

Mix dish soap and water about 50/50 in your mixing tub to get your degreaser (or just use you degreaser or alcohol if you have it).

Drop the chain in the degreaser and let it soak for about 2 minutes.

Step 3: Clean and Rinse

Take the chain out of the degreaser and run the chain through the rag to whipe off the excess grease.

Then, hose off the chain to get everything else off.

Step 4: Measure and Break the Chain

If the chain you got came in a loop, break the loop (mine came in one straight line, so this isn't documented).

Starting at one end of the chain, wrap it around your wrist till you complete the circle.

Depending on how tight you want the chain, you may want to put some slack in the chain while measuring.

Make sure that the link you measured at is the opposite link as the link at the end of the chain. For example, if the end of the chain you are working with is an inside link, the link you measure at should be the end of an outside link.

Hold onto the spot on the chain you just measured, as it is your wrist length and will be where you break the chain.

Then, using your chain breaker tool, break the chain at the measured spot.
Be sure to leave a little bit of the chain pin stuck in the end of one link as mentioned in the youtube video.

Step 5: Put the Chain On

This step may require a little help from a friend.

Take your chain segment and wrap it around your wrist. Put the two link ends together. It should take a bit of force and quseezing if it is a tight bracelet, and if you broke the chain right, there should be a little click as the links go together.

Have a friend hold the chain together as you use the chain breaker tool to drive the pin back in and complete the chain. This is quite hard but doable. Just keep trying.

...and voila! Your bracelet is done. Thanks a lot!

I will stress once again that this is a semi-permanent bracelet. It takes time and effort to get it on and off. Be aware of the effects that putting it on could have to your body and your life.
