Propulsion, a boat needs oars, I began with 3mm square oak strip and sanded down until the correct round profile was obtained, this allowed me to narrow the ‘poles’ in the correct areas. My problem next was the blades of the oars, anything made of timber was too thick, get it down to the correct thickness and it was too fragile, card was the same. So for the first time in this model I used plasticard of 0.5mm thickness, p323. These were attached by cutting a slot up the centre of the plasticard for the poles to fit into. The end of the pole was notched so that a tenon joint could be formed between the pole and the blade and then the two epoxied together.
