Introduction: Homemade Metal Bender
Step 1: Reticulated Frame
First, we made an horizontal, reticulated frame of square tubes of 60mm thickness x 60mm x 2mm, which has been placed on a basis. The basis of our machine as well as the horizontal frame are both motionless. A second frame with the same requirements of a structure includes our horizontal frame and it moves upwards and downwards within two metallic channels that we made.
The motion of the moveable part is vertical in the motionless frame. Any moves occurred in the frame are supported with the use of a hydraulic jack that exerts pressure up to 6 tones. This jack moves with the help of a lever that has been attached on it. Thus, moving the lever, the moveable metallic frame moves vertically on the horizontal framework with the potential to exert pressure of 6 tones. Then, we placed two metallic axes of 38mm thickness at the frame which remains still and another one the same at the moveable frame. In this way, placing the metallic object between the two axes and moving the lever of the jack, we make the object incline and bend.
Step 2: Axes - Channels
At the two edges of the three axes, we placed screws and we made special channels for wedges in order to be able to put attachments according to the shape and the thickness of the metallic objects that we need to bend. Taking benefit from our structure, we made a wheel that is placed at the central axis which is located at the moveable frame. As a result, giving the inclination that we prefer and orbiting the wheel continuously, we manage a constant inclination at the metallic objects that we want to bend such as tubes, square tubes, knife blades and others. Both sides of the axes have been modified as the one side can be used for a new machine in the future.
Also, we made special attachments for the edges of the axes made of metallic, perforated axes and plastic for bending the tubes and aluminum. Therefore, we achieved to bend iron at the center of the metal bender as well as at its edge. At the central point of the metal bender, objects of a larger diameter are placed as it is supported by both sides with omega bearing while at its edge smaller in size objects are put for bending but in various shapes and kinds.
Also, at the edges, we can achieve a larger inclination and make circles and arrows smaller in diameter. Furthermore, we designed our structure to function vertically and horizontally according to the available space that we have and it has been implemented having the perspective to transform our structure into an automatic machine in the future using a motοr if necessary.

It is highly recommended as it is very simple and useable as well as useful to thousand other structures and essential for us and to many other humans. Finally, it should be mentioned that at the sideways of the metal bender, wheels can be placed to move it easily. Also, it has been painted in green and black colour.
