The plan of Fig. 1 shows oneblock and the end of the straight edgeas it rests against the shoi Now take your maphrodites and setthem to this distance, i. e., from thestraight edge to L, which is equal onboth sides of engine, then lay that dis-tance off on the side of the shoe with theleg of the maphrodites placed againstthe straight edge. Do this on the othershoe on the other side of the engine, thenplace the straight edge on the long blocksin the same manner and repeat the opera-tion for the upper point L. Scribe a linethrough these two points just located onthe inside of the shoes.
