How to make a tubing for downhill skiing with your own hands?

Tubing - a special device for downhill skiing. In appearance, it resembles a cheesecake, for which he received the corresponding nickname. it an excellent alternative to sledges and ice-cakes. NSAt the same time, tubing is not cheap. However, the budget model can be made with your own hands.

The homemade snow cheesecake is made from a car camera. For a child over three years old recommend tubing with a diameter of at least one meter. Therefore, only a car camera will work. In addition to it, you will need:

• PVC material or waterproof polyester, you can use an old advertising banner or raincoat fabric;
• strong nylon threads, better LL No. 10;
• synthetic tape for processing seams.

Care must be taken in advance about pensto hold onto them when rolling downhill. They are made from synthetic webbing, or you can cut them from an old duffel bag. A metal ring can be sewn to the handles so that the cheesecake can be towed.

Making tubing with your own hands is not difficult, but it will take some skill.

Cover material need to be folded together with the right side inward to cut two identical circles at once. Put on top inflated camera. It is necessary to circle it along the outer diameter. The main thing is to make the calculation correctly, taking into account the allowance, about 15-20 cm.

Then on one circle it is necessary to cut out the middle - along the inner diameter of the chamber. This circle does not need to be thrown away, it will be used for the bottom. It is also necessary to cut a strip with a width of 15-20 cm and a length equal to the circumference of the cut circle.

Sew two circles on the outside... The seams must be strong. Treat them with synthetic tape. Sew on handles.

Sew along the circumference of the cut-out "hole" banner strip. Since the fabric is dense, not every sewing machine will be able to sew it. You may need to sew by hand.

The bottom is sewn in the last step.... The seam should not be continuous. You need to leave a gap to freely remove the deflated camera and put it back. At the same time, it is easier to shake out the snow from such a cheesecake - for these purposes, you can sew in a zipper or simply pull it off with a cord.

DIY tubing is ready. It remains to pump up the camera - so that it is elastic, but not rigid, and you can ride down the hill. You can pump it up yourself at home using a compressor or in a tire fitting.

The speed of the cheesecake depends on the choice of fabric.... If the material is non-slip, then the tubing will slide out more slowly, there is less risk of driving into a fence at high speed or entering the road. And so that the child can be clearly seen in the evening, special reflective stickers can be placed on the cheesecake.

If the cover breaks during operation, it is easy to repair it. A small gap (up to 5 cm) is sealed with "Liquid patch" or a special joint compound for PVC materials, for example, suitable for rubber boats.

The area is cleaned of dirt and degreased with acetone, similar actions are performed with a patch. Then you need to warm up both areas with a hairdryer and only then glue them. Leave for a day. The size of the patch should be 2-3 cm larger than the cut so that it completely covers the gap, a rounded shape is preferable. You need to glue it on the inside of the cover.

Larger gaps can be sealed reinforced tape... This material holds well, protects against moisture penetration, withstands mechanical stress and temperature extremes. The hole is also treated with acetone, then stitched with nylon threads. After that, the tape is glued to the inside of the cover.

If the gap is on the camera, then it can be sealed in the same way. The hole can be found by placing the camera in water. Bubbles will come out of the puncture. For better adhesion with the patch, the hole is cleaned with sandpaper and also degreased with acetone. You can use the services of tire fitting. If the camera has become completely unusable, then you can buy a new one in an auto parts store, the main thing is to know the radius of the old one.

Store tubing should be disassembled, that is, put the camera separately from the case. All parts must be wiped off dirt and dried. Subsequently, the camera should be inflated only at room temperature, while it should be in the center of the cover, otherwise there will be a clamp in one place and free space in another, which will lead to deformation and quick wear of the camera.

In some cases, the tubing becomes so unusable that it is easier to replace it.but this rarely happens.
