1in the inner pattern), but do not add the button to the figure.
3The joiner will now easily cut away the wood inside the inner outline, but the amateur may bore with a large bit numerous holes all round the inside, not working nearer than 1/4 in. from the inner line. The bit holes should not run into each other, and the bit needs greasing. Now with a mallet and chisel cut away the inside wood. With flat carving gouges and chisels work up to the inner pencil line, squaring incessantly when nearing it, but always from the belly face, when scrapers will be necessary. Before working out the corners, saw the lines in the figure with a fine dovetail saw. Do the work mainly with a penknife on the front and back, and deepen the upper and lower (back and belly), knife corner cuts till at last the cut is complete; then with fine chisels finish the corners.
5The saw line is prolonged to have extra space when fitting the ribs; 1/4 in. beyond the ends of the corners of the violin outline is ample; more would weaken the mould. Now with a chisel deepen the tips of the corners and make parallel cuts exactly where the inner corners end. The latter helps in marking where the ribs are to be trimmed off when out of the mould. It is useful also to join the two centre lines at the ends, inside the mould. Also as the lines, especially the corners and middle lines, become worn out, renew them with pencil and awl.
7The outside mould is now complete. The difficult cramping blocks of the inside mould are dispensed with, which is an advantage, because if the blocks are not made very truly, they are troublesome, the work of fitting the hollows in the inside mould being far more difficult than anything in the outside mould just described. Again, the difficulty of affixing the linings in the inside mould is very great, as it is impossible to see whether the under edges gape or not, and bad-fitting joints are very liable to occur.
