This is a great looking bracelet made out of Bicycle Chain that serves a dual purpose!  It has tiny magnets glued to it so that you can use it as a parts holder.  Never loose those little parts again!

I teach a class on Bicycle Repair to 7th and 8th graders.  It seems I always catch one of them trying to permantently attach a chunk of bike chain to their wrist as a bracelet.  Two problems with this:  the chains are always FILTHY and no amounts of degreasing, scrubbing, cleaning, or soaking would keep them from turning your wrist black after a few hours of wearing it.  The other problem was they were trying to put them on using the chain breaker, which is pretty permanent, and in my opinion just a little unsafe...

My solution uses an easy to remove "clasp" to take it off or put it on, and by starting with a new chain, no more black wrists!

Step 1: Gather Your Junk.

Pretty simple supplies list. 

Tools & Supplies:

Chain Breaker (or a grinder will work if you are careful)
Glue.  I recommend JB weld, the gorilla glue didn't work on all of the magnets.


NEW bicycle chain (about $15.00)
Neodymium Disc Magnets 1/4" X 1/16" (I bought a pack of 100 for abt $12.00 shipped)
Small bolts or rivets

Thats it!  I figure you can make 4 bracelets easily with one chain and one order of magnets, so each bracelet would run about $7.00. Less, if you use less magnets and can get more than 4 out of a single chain.
cool, you did a good job
I may make this
couldn't you use a magnetic coil to magnetize the metal of the bracelet itself? or is it non ferrous?
i might just make the "chainlet"(o wait that sounds like some sortov naughty lingerie :/) bracelet coz it looks awesome but incorporate the magnet locking system
Helpful , it sure works. I spent a lot of time loking for small nails, bolts, washers and what so ever small part dropped down on a natural surface outdoor ground and mostly I don't like the taste of blue marine grease in my mouth. Regular neodimium magnets are nickel plated because easily rust (black ferrite magnets don't rust but are bigger and weaker) so some kind enamel protection should be considered unless you use the little more expensive gold plated ones. I must say that thin neodimium magnetets are not so hard to chip, it happened to me a couple of times but I can't tell wetther it was defected stuff or not.
Nice idea. I have a suggestion: if you alternates South and North magnetic poles, you will gain an extra fastening force.
Good to know! I did notice as I was putting the magnets on they had a tendency to flip opposite of the one next to it, so most of them ended up that way anyways.
