A vertical ispindle moulding machine, with a cutter block similar to that shown by the sketches below, is the simplest thing to use for bevelling the frames, and for cutting out the curved part B (Fig. 1). If a spindle machine is not available and large quantities of frames are to be made, a strong lathe-head could be fixed in a vertical position to a strongly framed wooden table, and a cutter block and two irons fitted. The diameter of the block, with the irons, would have to be twice the breadth of the splay, as indicated by the dotted circle at Fig. 1. Fig. 2 is a front view of the block and irons, Fig. 3 an end view of the same, and Fig. 4 is a conventional view of the block.
