This cardboard kayak is very fun to make and play. you can make it from old cardboard boxes you can get for free. it costs about 25 dollars to make depending on what tools you have. Now, that explained let’s start building it.
3.mesuring tape and pencil
1. 5 pieces of cardboard about 4ft x 4ft
2. Contact adhesive
4. Measuring stick about five feet long [can be a long piece of wood]
5. School glue
6. Tek bond super glue
9. insulating foam
10. Tooth pins
11. Wood sealer
Put glue on top of both cardboard pieces, as shown, with the spatula. Wait till it dries, you know it’s dry by putting your hand on top of the glue, if it doesn’t stick you’re ready to glue both cardboard pieces together with someone’s help.
Glue all five pieces of cardboard together to make a super thick cardboard, then get your ruler or measuring stick and stylet and cut all of the edges so that the edges become parallel to make a perfect piece
Now I marked 25 centimeters from the beginning as shown in the first picture, then from the 25 centimeters I marked 40 centimeters, and from the 40 centimeters I marked 25cm again. From the last 25cm mark I made a line across and cut the rest off and keep it for later. Then I made lines across the cardboard from the 25cm 40cm and 25cm as shown in last picture. It should stay 80 centimeters across.
Now I made a line 50 centimeters from the beginning
and marked across with the stick. It should look like the last picture.
Now measure three centimeters from the top right side and then to the left side also as shown on the last picture.
Make triangles across the two top rectangles, that stay in the top corners, as shown.
Measure the top middle space that should be 40 centimeters. Mark the exact middle on twenty, and then make 2 lines to make another triangle as shown.
Now mark with blue the parts you are going to cut, then scorch it with your measuring stick and stylet. Put the cardboard on its side and cut it with your stylet. Keep the parts you just cut off because you’re going to need it later.
Now scorch the cardboard just a little with your stylet and measuring stick, for the cardboard to bend up.
Now scorch the front part and bend it up.
Tie both sides up with the wire.
Get the part you cut off earlier, measure it on the back of the boat and cut 6 pieces de same size to make a super thick piece to put on the back of the boat.
Glue all the pieces together and drill them with four screws. Drill it in the end of the boat with other four screws.
Now glue two pieces of Styrofoam together and then glue them to the boat as shown.
Now cut some Styrofoam pieces. Put glue on them and glue it to the boat’s seat.
Drill the front together and put tek bond super glue.
Measure some more Styrofoam on the top front part then cut and glue in the front part. Next glue the parts you cut off from the rectangle, as shown.
Take the cardboard to your yard and wet it the hoe. When the cardboard gets wet you can easily peel it, put it out on the sun to dry, with rocks on top so that the wind doesn’t blow it away.
Leave the cardboard drying outside while you cut some more Styrofoam. Measure it on the boat and cut it, then glue the Styrofoam to the boat and put tape to hold it till it dries.
You can remove the wire that was holding the cardboard side up. Then put isolating foam on basically all the cracks you find, and put a rock on front of the Styrofoam to hold it from coming forward.
Now bring the cardboard that was drying outside and keep it to be used in step 22. Cut off all the extra foam.
Bring the two triangles you cut earlier and glue them to the front of the boat. Then screw it down as shown in last picture.
Measure all the parts of the seat and cut the cardboard you peeled before to cover the seat. Glue the peeled cardboard on the seat and use tooth picks to hold it down while it dries.
Do the same on the front side, and put tape to hold it down while it dries. then cut another piece of cardboard to put on top and glue it with hot glue
Now bring the peels you peeled off and cut them into strips, and glue it
everywhere you see cardboard ends showing, you
can also print pictures to decorate your boat.
Now put tape all around the boat starting on the side and going around till the other side. Keep putting tape till you finish the first side then turn it on its side and keep putting tape till you get to the bottom then turn it around again and and do the last side as shown.
Step 26: FINAL STEP
26th step FINAL
Now put wood sealer inside and around the boat then wait about 12 hours to use your boat to give all of the glue and sealer time to dry.
