The jug in Fig. 267 is fitted with a half-round hollow handle, and if it is desired to make this in one piece, the pattern for same can be struck out as shown in Fig. 269. A quarter-circle is described on 0 c and divided into three equal parts, lines then being run along to the joint line 0 x, and up, to give the points a and b. The girth line of the pattern is laid out by taking six divisions, each equal in length to one of the arcs on the quarter-circle added to 3 D, which is the width of the handle, and equal to twice 3 c. The points A, B, and C on the pattern are found by marking off 2 A, 1 B, and 0 C respectively equal to x a, x b, and x c from the elevation.
In forming this handle section, the part 3 3 will, of course, be shaped into a semicircle, whilst the portion 3 D will turn over to give the flat. The joint will run along one edge, and after this is formed, the mitre can be made by simply bending along the line 3 D until the two curved edges, 3 C 3, come together.
