I'm sure you have seen that it is possible, but what if we want a metal ring with a gemstone on it?
We can, using soldering tin wire and a gemstone that has an excellent look and costs just about 2-3 couples of coffee.
Except the gemstone, we will use only materials and tools that almost everybody has already around house, that is always a good thing, beacuse trying to do something using only things that you already have leads to more Efficient use of resources, less waste and this is a good steep toward a greener planet... and also cut down costs ;)
Not to mention you don't have to out to buy materials and tools...
1) Use Lead Free Tin Only.
2)This instructable is for entertainment in making a piece of jewellery.
It is not supposed that you make a ring that you will wear for the rest of your life.
Instead it should be an item that you place on some cushion and say "I made it", or for your girlfriend to say "my boyfriend made it for me" when friends will come to your home
Step 1: Materials
-Soldering tin wire
-A 3v battery, or 2 AA batteries, it doesent matter as long as it gives enough power to the
-Small electric motor (Usually requires 3v) to spin with enough power.
-A metal bottle cap and a small metallic object with a cilindrical shape
(Later we will discuss about it)
-Extra: some electric wires, small pieces of PVC or similar material, paper and pen, a solid cutter and some grinding paper.
