The tiller is scratch built from 1.5mm wire and 2x2mm walnut strip. Using a length of 1.5mm wire cut to 60mm long form the
tiller handle by tapering from 1.5mm at one end to 1mm at the other, using a file or other abrasive material. Using pliers,
introduce the shape into the brass as shown on Plan sheet 4. The handle cap is made from a small piece of 3mm dowel and
painted red ochre. After shaping the tiller handle should be cut to approximately 43mm long.
The tenon is fashioned from a 10mm length of 2x2mm walnut strip. It should remain square throughout its length but be
tapered as shown on Plan Sheet 4. A 1.5mm hole is drilled in the forward end to accept the tiller bar which should be glued
into position.
The opposite end of the tenon is to be located in the mortice of the rudder head. The tenon should be painted red ochre and the
tiller bar painted matt (metal) black (Photo 040).
The rudder mortice is drilled into the headstock of the rudder and will take the tenon of the tiller. The drill should be kept
parallel with the top and bottom edges of the rudder as you proceed with the following considerations:
1.
Use a 1mm pilot drill to start.
2.
The hole is drilled fore and aft.
3.
The hole should be positioned 2.5mm down from the top edge of the rudder.
4.
The hole should be drilled centrally and remain central along its length.
Once the hole is drilled, it should be enlarged using a small file and made square, do not exceed 2mm square. Ideally the
mortice hole should be slightly tapered to accept the tiller tenon. The rudder can now be re-positioned on the model (Photo
040) and the tiller inserted into the mortice (Photo 041).
