The draw-spike, G, is driven into the pattern by means of the rapping-bar, H. The wood screw, M, is also used for drawing patterns. If the patternmaker has put threaded draw holes into the pattern, which is often the case, the draw-screw, J, should be used. A molder should supply himself with a set of small tools. It is common practice to see an apprentice select all kinds Fig. 30. — Molders tools. and sizes of tools, only to find later that he has many for which he has no use. That is a mistak...e. It is better to select a few tools and add to them when necessary. The illustration. Fig. 30, shows a set of tools that will meet nearly all of the requirements for bench or floor molding in commercial foundries as well as in schools. However, for special work, many other tools are needed. The trowel, A, is known as the finishing trowel. The one shown at B, is called the square trowel. These trowels should be about V/^ in. Wide and from 5 to 6 in. Long. The lifter, C, is used chiefly for floor work and usually two lifters only will be necessary.
