-   Using a vice or clamp, firmly grab onto the 0.5 x 13.5 inch rod S16B with the end extending out around 2 inches from the edge of the vice/clamp. Mark the dimensions as shown in Figure 3. Carefully use a center drill to start the a center hole for these holes. It is important that the center hole is as centered as possible to prevent the bit from walk- ing/slipping during drilling, which could result in the bit breaking. Then, use a #23 (0.154 inch diameter) drill bit and drill all the way through both sides of the rod. This makes the S16B’ part.
