Select the material to make the pipe. You’ll need a sheet of fine galvanized tinplate. Such metal is corrosion-free and is relatively easy to handle the most common tools.
Draw a sketch of a future pipe. Put its dimensions on a piece of paper. Then transfer the pattern to a pre-prepared tinplate sheet. By making a pattern, consider that the width of your workpiece should be equal to the diameter of the future pipe, to which approximately one and a half centimeters should be added. For a straight pipe, the length of the workpiece should be slightly more than the required size.
Using scissors for cutting metal, cut the painted pipe workpiece from the sheet. Place it on the edge of the workbench or another flat horizontal surface. Along the length of the leaf of the tinplate, draw on one side the line of the falcon, retreating from the edge of half a centimeter.
Now match the drawn line with the workbench edge. Curb the edge of the sheet down with blows of the kiyanka. Now turn over the workpiece and turn the edge to the sheet with very light bumps of the wooden hammer.
Turn over the sheet of metal again and turn the edge back to a centimeter, but in the other direction. The bend profile should resemble the letter “G”. Put the workpiece thus prepared in the mandrel and gently rotate the edges of the sheet to each other with your hands.
the edges of the sheet into a “lock” so that the smaller of the edges is hooked to the larger size. Using pliers, seal the edges, and then with the help of a metal bar and a normal hammer, well finish the connection place.
To give the finished pipe extra strength, clip the edges of the tin pipe with aluminum or steel rivets. To do this, prepare holes in the pipe, taking a step between them in about three centimeters. Insert the right size rivets into these holes and make the connection using a normal hammer. Now the pipe is fully ready for operation.
