Hi! I'm Mark Sullivan for Expert Village and today we are going to learn how to build a barbecue pit. So we have determined the proper placement of the opening in our primitive backyard man made fire grill pit here, so we've cut out steel, mesh and we are ready to put some more of these hexagonal blocks in place. I am just going to start right about here. I don't really want that to stick out so I am going to move that a little bit like that and then we will continue. Now again we did purchase more of these hexagonal stones so most of the materials I buy are seconds. So some of these seconds may be just colored or kind of a blending of colors but you know, they are imperfect.
