Next Tock set to work on a set of picks. They were a rather simple design, just a length of iron with a pointed tip. She just needed to make several of different lengths and widths, some with sharper points, some narrower. She was able to do most of this task without much guidance from Harold. A couple of the thicker picks required a bit of upsetting, shortening the length while thickening the width similar to how she had done with the hammers. Then she set each one at a different angle on the anvil, depending on how fine of a point it needed to have. Steady pounding on the iron while rotating the piece in place allowed her to shape the tip to a fine point. As each pick was shaped, she used a chisel to cut the excess iron off the end, then stuck the back end of the iron back into the heat. Once only the back end was heated, she pulled the pick out and laid it horizontally onto the anvil, with the heated end hanging just off the edge. Then she pounded the small heated length of the metal from the side, flattening it and widening it into a metal cap. This would be the part she pounded on when driving the picks into the stone. Next she began work on the chisels. In between his own continuing work, she checked with Harold for some advice on these here and there, to be sure she got the technique right. For each one she began by drawing out the iron to create the flat blade for each. Some were only an inch or so wide, and this was a fairly simple process. Some needed a rather wide blade, however, and she had to upset the metal to thicken it, before flattening it out into the wide shape of the blade. She then added beveled edges the same way she had with the knives. One of the differences here was that the chisels would have all metal handles, unlike her current set of chisels that had wooden handles. Cutting through stone required firmer strikes, and a wooden handle would most likely crack under the force used. So she added a flat end cap to the handle just as she had with the picks, giving a wide, solid place to strike when she was driving the chisels into the stone. She made eight chisels in this way, two identical sets of four with blades of varying widths. To deal with thicker pieces of stone, one of the two sets needed to have teeth like a saw blade. After consulting with Harold, she began cutting out the teeth by heating the metal and punching through it with a thin blade, slicing out triangular pieces in a row across the bottom of each of the second set of blades. |
