Hi, I'm Mark Sullivan for Expert Village. And today, you're going to learn how to start
fire with friction. So this is kind of what we're after is this arrangement. Now we're
going to make another block that goes up here. I think, yeah this may work. We'll see. I'm
not exactly sure. You know what? I just realized that we're going to need to do one of two
things. One, we're either going to need to cut this is half. I think that's what we're
going to do. We're going to cut this right there and then we're going to shorten this
stick. This stick is too long, so we're going to cut it right here. Now we're almost ready
to just break it and then we will have our... We're going to make this a bit of a rounded
point here, so that we'll have a larger surface area in contact with our base. And what I'm
doing now is making the base of the spindle rounded so that we can have it into the top
bearing so it will stay straight and we can control the spinning. It gets a lot of revolutions.
