For this homemade product you will need two steel pulleys of different diameters (large and small), a piece of channel, two strips of metal, as well as pieces of round timber of suitable diameter. Of the main tools for making a pipe bender, you will need a drilling machine, a grinder with a cutting disc and a welding machine.
Step-by-step manufacturing process
As the basis for a self-made pipe bender, we will use a piece of a channel in which it is necessary to drill a hole for a steel "finger", machined from a round saw on a lathe. Insert the "finger" into the hole and scald in a circle. We put on a large pulley.
Next, cut two steel strips to size and drill two holes in them on a drilling machine. One strip is mounted under a large pulley, the second on top. We insert another steel “finger” into the second hole, on which a small pulley is put on. You will also need to weld a handle from a round log.
At the last stage of work, we weld a piece of a corner or plate 3-4 mm thick at a right angle to the channel at a certain distance from the large pulley, which will act as a stop. The base of the pipe bender is welded to the plate, which is attached to the surface of the table or workbench.
To summarize
The design itself turned out to be quite simple and budget, but for home use it is quite suitable. With this device you can bend not only pipes, but also rebar or steel bars of circular cross section. For a detailed process of making a pipe bender, see the video on the site.
