By producing repair with your own hands in the house, or equipping your land plot, come across the need to bending metal, aluminum, copper, etc. pipes under different radius.
How to make pipe bending
Such a need arises when installing heating, wiring or water supply in the house, construction of a greenhouse or a greenhouse, a canopy for a porch, a frame for grapes or flowers and much more building. Pipe bender is the tool that will help you to generate pipes under the desired radius. About how to make such a pipe bender with your own hands and will be discussed in this article.
For the manufacture you will need a square pipe with a size of 5x5 cm. And the thickness of the wall is 2.5 mm. Sut off the two blanks of a long 40 cm and one 60 cm., Weld as in the figure.
In the upper jumper we drill a hole for the size of nuts with a threaded needle. Applying nuts, top and bottom of the pipe, weld them and screw them with the needle. The length of the middle tube (piston) is 12 cm, it should move freely along the vertical.
By putting the top jumper correctly, after installing the piston, we grab it to the racks.
I weld the knob to the knit.
Having placed the piston in the middle of the racks, the horizontal line is drawn, on this line we weld the side ears long 6-7 cm.
The next step is welding stiffery plates on both sides of the frame.
Do not rush to brew all the docking seams finally, it is enough to grab the plates in order to drill through holes for overhead bearings.
For the roller mechanism, we use body bearings. They are the same housing assembly which consists of a spherical ball bearing pressed into the case of cast iron. Also rail roller roller roller rings and axis, which they are going along with bearings.
In these photos, it is seen in detail the order of twisting bearing and assembling axes with rollers and asterisks under the chain.

Making advantage of the clear and smooth operation of all rotating nodes, remove the bearings and dislike all the sticky parts, joints and ends, we weld the transverse legs from the pipe 5x2.5 cm.
We select the chain and connect it on the place, to any of the star sides to the nut we weld the rotating handle.
Pipe bender is ready for work, the rotation of the middle piston spokes is set to the height of the roller, thereby regulating the desired radius of the rolling bend. The rotation of the chain transmission is reproduced by the tube on the rollers.
