How to Polish Rocks: Part 2

"Hi, I'm Jason with expertvillage.com. We've just finished the second bit of sanding and we used the 220 grit-sanding wheel on there. We're going to mark from scratches again, but there's going to be a lot less as we go on. By the time we hit the third polish, we probably won't have any scratches left at all. And one thing you've got to remember is to ground your edge down on the very first step. And even though you did that once, and you feel like you're getting the whole surface, if you don't do the edge every single time with the grit you're going to have a big white line around the whole thing. It's not going to polish there at all and it will look really ugly. So, as you look for scratches or mark for scratches, you need to remember: you're going to do the scratches and the edges all on this next step. And try not to reshape it at all. Just go over the edges real quick and take out the scratches with the 220. I'm not going to mark it because I can see them, I know what I'm looking for and I don't see very many. It's going to take way longer to mark them than it is just to take them out. So in the next step I'll just demonstrate really quick with the 220 and then we'll move on to the polishing steps."
