The hunters saw such sticks and will understand me. After browsing on the Internet everything that has been done in this direction by both our and foreign craftsmen, summarizing their experience, set to work. Initially, I wanted to make a boat out of PP sheets, but this option turned out to be very expensive. The price is 5 times more expensive than FSF plywood. I had to abandon polypropylene, and take plywood 8 mm, which is also probably a mistake.
The boat turned out to be heavy-24 kg, and even a set of frames, transoms, stringers and mounts-6 kg. But the idea was to deliver the shuttle from roads to spills or ditches leading to spills, on foot along forest paths. I already tried wearing. It is possible, but difficult. The manufacture of 5 mm plywood will facilitate the design itself, but will create additional difficulties in fixing parts of the kit. In 8 mm plywood, I boldly screwed a 10 mm screw through a piano or window loop and with a large number of them everything is firmly held. For a set of 5 mm plywood, it will be necessary to fix it with rivets, a screw-nut, additional slats and washers.
There are also problems with PVC fabric. For gluing the joints of the sides and parts of the bottom, it is necessary to use a fabric with a thickness of more than 1000 g / m2, but I managed to get only 700 g / m2. I got out of the situation as follows. I glued the joint first with a thin strip with an overlap of plywood of 7-8 cm, and then glued another layer on top with an overlap of 10 cm already glued. Glued it with polyurethane adhesive UR 600 in a hot way. Everything else can be viewed in and video. If you have any questions, please contact.
