"Hi, I'm Jason with Expert Village. Today, we're making a charm out of rock. We're going to polish it up and make a charm for a necklace. We've already chipped off a piece of rock and there's a couple of things you need to know before we start actually polishing it. The Dremel and the bits get really hot, the rock gets really hot and it will shatter and break and cause all kinds of problems. It'll even burn up your Dremel. So, we have water. Keep plenty of cold water and just keep it wet. And with your Dremel, you don't have to work in the water but don't work on it any longer than five or ten seconds on the rock with any bit without putting it back in the water. That will also keep the dust down so you're not breathing a massive amount of dust. You'll get it up in your nose and your lungs and it's hard to get out. So, before you do anything, make sure you got your water and the first thing we're going to do with it, we're going to drill a hole. For the charm, just look at the shape of the rock and where it will fit nice on your chest. Just vision like where it would sit. This would probably be the back area where it could sit on you nice, which means you probably want the hole somewhere in this area of the rock. You're going to grind a lot of this down, so you want a thick part to go through. So, I'm going to say about right here where you can go through with your bit. So, in the next step, I'll show you how to drill through the rock."

on 7/22/2009 Hi Jason,
I was wondering if you could lay out specifically what bits you used for drilling, sanding, polishing etc. I've been to Home Depot looking for the bits for my Dremel, but didn't see anything that looked like what you used. So if you could be more specific on the bits and maybe provide a link to a place where I could order them, I'd really appreciate it. Thanks for the great tutorial.
