The work involved in the making of a sheet-metal kerb fender is of such an elementary character that the ordinary workman or amaterr craftsman should find very little trouble in making one up to his own design and liking.
The kerb may be made out of hammered or polished sheet copper or brass, or even be made out of plain sheet iron, and afterwards blacked or japanned. The setting out of the patterns for a very simple shape is shown in Fig. 79.
The form of the section, it will be seen, is drawn on the plan of the fender, this being afterwards divided up into four parts, 0 to 1, 1 to 2, 2 to 3, and 3 to 4.
The girth line 0', 1', 2', 3', 4', on the pattern is first laid out, the lengths of the different parts being taken from the corresponding lines on the section. Lines are then drawn square to the girth line through each divi-sion -point, and these cut off the same length as the corresponding lines drawn through the division-points on the section parallel to the front of fender, and running up to the joint lines C B, A 0. On
Fig. 79 the lengths are shown cut off by the dotted lines projected from the plan on to the pattern.
The cut on the pattern for the end will, of course, be the same as that for the front, hence the one pattern will do for the two parts. The length for the end will be obtained by making 0' D' equal to 0 D.
Without the kerb is made of strong sheet metal, it will be necessary to have a wooden core, of the section shape, to which the edges of the sheet metal can be nailed.
A corner cover is sometimes used, and if this is required, some such shape as that shown in Fig. 79 can be adopted, it being bent up over the joint and fastened along its edges with nails having ornamental heads.
If a corner cover is not used, the mitring will have to be done very carefully if the fender is to look neat; but in the event of a cover-plate being attached, there will be no need to bother with accurate joining at the corners.
If the fender is made of copper or brass, then any degree of ornamentation in the way of repousse work can be put upon it, depending upon the skill of the craftsman and the time at disposal in making.
