When performing large volumes of work with sewer pipes, it is good to have a pipe cutter available. It allows them to be cut quickly and immediately with a finished chamfer easily passing into the socket. To save money, you can make a pipe cutter yourself.
Materials:
- coupling 110 mm;
- clamp 110 mm;
- sewer pipe 200 mm;
- wire;
- glue;
- square rod 10x10 mm;
- threaded rod M12;
- profile pipe 20x20 mm;
- PP pipe 20 mm;
- screws, nuts.
Pipe cutter manufacturing process
A clamp with a twisted bracket is put on the coupling.
Then you need to cut 3 rings from a 200 mm sewer pipe.
Of these, 2 are 4.5 cm wide, and one is 9.5 cm. The rings are cut lengthwise.
One of the narrow rings is shortened and pulled onto the lubricated coupling.
A second narrow shortened ring is placed on top of it with glue.
The third wide one is glued in with an outlet beyond the coupling. For reliability, you need to solder twisted heated wire onto the seam of the last ring.
A cutter is sharpened from a square rod.
After this, a threaded rod is taken and a hole is drilled in its end into which an M6 thread is cut.Then a screw with an M8 nut threaded through it is screwed into it. After this, the end of the cutter is welded to a nut rotating on the screw.
Taking a 12 cm piece of profile pipe, you need to cut its edges at 4 cm from one end. Then the walls of the cut edge are bent outward at a right angle. An M12 nut is welded to the straight end of the pipe.
A square hole is cut in a wide ring on the pipe cutter body to the side of the coupling. You need to insert a cutter into it, the pin of which is screwed into a bent profile pipe. The pipe eyes are then screwed to the pipe cutter body.
3 nuts are screwed onto the stud connected to the cutter. One will work as a lock nut to fix the cutting depth, so it is tucked into the profile pipe. The rest will serve as a handle holder. They need to be heated and a plastic water pipe pulled over them.
Next, you need to make a handle similar to the one on the cutter from the pin. It is installed on the clamp. Before this, you will need to drill the wall of the coupling so that the pin fits inside it. If the standard clamp nut does not fit, then M12 can be welded instead, since a thinner pin may bend under load.
To use a pipe cutter, you need to put it on the pipe. Then press the handle on the clamp to fix it. After this, the cutter is slightly pressed, and the handle with it is turned in a circle with periodic screwing. The principle of operation is the same as that of a seaming wrench for preserving workpieces.
