Step 1: Materials and Tools
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)
Bicycle chain breaker tool
If you don't know how to use the chain breaker, check this out:
You don't have to watch the whole thing but it will help.
Step 2: Mix and Degrease
Drop the chain in the degreaser and let it soak for about 2 minutes.
Step 3: Clean and Rinse
Then, hose off the chain to get everything else off.
Step 4: Measure and Break the Chain
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
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.
