How to build a raft? If you need to transport a lot of equipment and food through a water obstacle, or want to go down the river, best to build a raft – The simplest floating structure. Tree trunks are a traditional material for building a raft, However, it can also be made of bamboo, reeds or gasoline barrels. When building a raft, you should make as little cuts in the logs, which is associated with it, Thanks to this she will be flat. The raft must also be very stable. This type of water transport is useless on rivers, in which there are Porohy and Bystrzyny. They threaten to break the raft. If possible, You should try the raft on shallow water before sailing to the deeper.
Raft construction
1 You need to cut it on board 12 do 14 fat, strong trunks. They should be leveled, to be the same length. Besides, you need to cut six more trunks – longer 30 cm from the planned width of the raft. They will be a raft skeleton. Arrange two longer logs on the ground with two shorter. It will be a platform for floating the raft.
2 Make an incision with a large knife on all structural beams. They cut them along the entire length, leaving after 30 cm from both ends. The cuts should have a depth in half a beam. Be careful, so as not to cut the beam too deeply, This weakens her load -bearing force.
3 Arrange the cut beams next to each other, check, whether all cuts are the same length and depth. That the deck is equal, Long logs should lie flat on structural beams.
4 Arrange two beams at the opposite ends of the platform, cuts up. They will be the main support. On them, start laying long on -board beams.
5 The on -board beams must be laid on the cuts, Starting from both ends going inside the raft. Change the thickness of the on -board beams, so that they burden the beams evenly, on which they rest. Turn them when laying, that they lie next to each other as much as possible.
6 Last, The central deck beam should be simple and strong and so thick enough, that it fits tightly on board between the arranged beams. You should take into account this, that you will need to improve the deck and additionally tie beams on the water, to stay in their places.
