Easy and strong do-it-yourself pipe bender without turning and welding 

I recommend repeating. If you don't have welding, it doesn't matter. If there is, it's even better.
The shaft for this pipe bender is here: • САМЫЙ ЛУЧШИЙ вариант. ...
1. It is mobile: it is easy to transport it to any area, even by bicycle.
2. It is serious in performance (it rolls at the same time even a couple of the most popular 20x20 profiles in greenhouses).
3. Has a reliable, durable broaching shaft.
4. Having drawings, it can be easily assembled by any guy who has a firm hand and understands space.
5. And finally, it is assembled without the involvement of a turner and a welder.
During the tests, this car proved to be excellent, and I can safely recommend this model for repetition.
