In modern individual construction, new technologies are widely used, but sometimes there is a need for simpler things. What if, say, you need a tin pipe of a certain size? Such designs are often used for the manufacture of water drainage systems. If it was not possible to find a pipe of a suitable size in the retail network, you can make it yourself.
It is necessary
- - thin sheet metal;
- - scissors for metal;
- - metal bar;
- - steel or aluminum rivets;
- - crafting table;
- - roulette;
- - ruler;
- - metal scribe;
- - an ordinary hammer;
- - a wooden hammer (mallet);
- - mandrel;
- - pliers.
Select the material for making the pipe. You will need a sheet of thin galvanized sheet metal. Such metal does not corrode and is relatively easy to process with the most common tools.
Draw a sketch of the future pipe. Place the dimensions on a piece of paper. Then transfer the pattern to a pre-prepared sheet of tin. When making a pattern, keep in mind that the width of your workpiece should be equal to the diameter of the future pipe, to which you should add about one and a half centimeters. For a straight pipe, the length of the workpiece should be slightly larger than the required size.
Using scissors for cutting metal, cut the drawn pipe blank from the sheet. Place it on the edge of a workbench or other flat, horizontal surface. Along the entire length of the sheet of tin, draw a fold fold line on one side, stepping back from the edge of half a centimeter.
Now align the line you drew with the edge of the workbench. Bend the edge of the sheet down with blows with a mallet. Now turn the workpiece over and bend the edge to the sheet with very light blows of a wooden mallet.
Turn the sheet of metal over again and use a mallet to bend the edge a centimeter, but in the other direction. The bend profile should resemble the letter "G". Place the workpiece prepared in this way in a mandrel and gently bend the edges of the sheet towards each other with your hands.
Connect the edges of the sheet in a "lock" so that the smaller of the edges is caught on the one that has a larger size. Use pliers to seal the edges, then use a metal strip and a regular hammer to tap the joint well.
To give the finished pipe extra strength, fasten the edges of the tin pipe with aluminum or steel rivets. To do this, prepare holes in the pipe, taking a step between them about three centimeters. Insert rivets of a suitable size into these holes and make the connection using a regular hammer. The pipe is now fully operational.
