The steering-gear rack (Fig. 165) by which the amount of helm is adjusted is made from a strip of brass cut with lugs which are bent up at right angles as illustrated. This need only be of thin sheet metal, as the strain is very small.
For running before the wind, separate lines are used, two in number, as illustrated, and the amount of helm is governed by the distance away from midships that the lead is moved. For instance, if the lead is placed amidships, the pull will simply keep the rudder dead straight, whereas if placed on the deck edge it will allow the maximum amount of angle.
Your bowsers can be made from pieces of toothbrush handle or from brass or German-silver wire. Very efficient bowsers can be made from aluminum tube cut in sections about 3/16 inch long, with three holes drilled in each piece around its periphery.
Plaited bobbin cotton should be used for the cordage, as it does not curl up when wet.
If you decide to fit the Braine steering gear, a spur or bumpkin, as it is termed, must be fitted to take the rubber centering line.
