The pieces s and t, and the tiller v, having been forged, as shown in [Fig. 2991], the upper member of the frame is started on the porter-bar at w, [Fig. 2983], and filed, welded and drawn to make the job as far as x1. Wooden templates, such as in [Fig. 2992], are provided for the pieces of the frame, the first extending from w to x1 and x, and the second including the part from x1 to x2 and x3. After w, x1 has been drawn out with lumps left where the tiller and the arm s are to be joined, the scarf is made for the tiller and that is welded in, and the job finished to piece s. The scarf for s is then made, and s welded in. This makes the upper member of the frame. The lower member is made in the same way, starting at x3. These two members are shown complete in [Fig. 2993]. The post, [Fig. 2989], was sent to the machine shop, and was turned, planed, bored, and slotted, as shown in [Fig. 2990]. The frame was now ready to be pieced up, by welds at w, x, x1, x2, and x3, [Fig. 2983].
