■ The raft deck instead of the tree trunks can be made of thick bamboo stems. It must consist of two layers, because one will not provide sufficient displacement. Instead of structural beams above and under the deck, In the walls of bamboo stems you can cut holes and pour the string through them by binding the deck together. You can also link any stalk with neighboring ones as an additional reinforcement.
■ It is difficult to predict before launching the raft, How will he float on the water. Using some species of wood, the loaded raft can slightly immerse under the surface. However, as long as it swims, Suitable for use.
■ rafts are not control. When making a refund, you need to remember and tilt the rudder in advance.
■ Avoid rafting collisions with edges and other obstacles, Because they weaken its construction and may end up with a bond breaking.
Structure of the raft part 2
7 Place the second pair of cut structural beams across the deck, cuts down, Exactly over the support beams. In this way, from both ends of the raft, the deck will be captured between two beams connecting the entire structure. Remember, that in the water of the deck beams will be held only by both pairs of structural beams.
8 Both pairs of beams with cuts should be very tied to. Nodes must be tied as closely as possible. Thanks to this, the deck beams will be squeezed through the lower and upper structural beam from both ends of the raft. The knots should be on the top beam, so that after launching they can be easily checked and improved.
9 Tie the lower and upper construction beam on both sides of the raft. Make a flat knot.
10 Check, whether the string strictly fades the beams and whether the nodes are sure. If you have time, You can additionally tie structural beams in the intervals between the deck beams.
11 Tie two thick poles on the cross. They must be so strong enough, to keep the rudder weight.
12 The support should be entered between the deck beams at the back of the raft. If it did not fit, You have to turn the poles on the node, crossing them at a different angle. The support is not attached yet.
13 A handmade oar will serve as a rudder. If you want to control standing, You have to make a long rumpel attaching a stick to the control paddle.
14 Check if the rudder lies properly on the support. If so, Take him to her with a string. The helm and support are attached to the deck beams only on the water, so that they do not break when launching a raft. The raft should be large enough, aby mogła unieść Ciebie wraz z całym bagażem. Before you load things on board, Check if the raft is swimming.
