  Materials Required:— A slip of thin wood, a small strip of tin, strong round elastic, strong tin cutters, a penknife or fret saw, an awl. Fig. 96. This is a little propeller which with certain alterations can be fixed to any boat. Take a piece of tin, as in Figure A, and pierce it with two holes and file them quite smooth, and slightly bend either end left and right from the holes. Now take a piece of thin wood cut as in the diagram, with a long wide slot, so that it forms a sort of fork, and with screws or tacks hammer this on to the stern of your vessel at the two holes, so that it projects with the whole fork clear of the vessel. Now thread strong elastic through the holes in the tin blades of the propeller with the ends knotted firmly, making a double loop, each end looping over the respective forks. Twist |
