The bending machine is adapted to my needs. To make the bending rollers, I used sliding gate roller that I once bought with the intention of building a mini wood sawmill but plans changed and I decided to use the rollers in this project. The electric gear motor 0,55KW I used is too fast to drive such a bending machine, so I had to use an inverter to reduce the speed. The bender worked very well, bending evenly and precisely, without deforming the pipes.
This project was made with this welding machine SSimder SD-4050Pro, Link to the welding machine :

If you purchase SD-4050 Pro (2024) during the anniversary event, you can upgrade the welding gun and ground clamp for free and receive free gifts.

In this video, I used a 3D printer for the first time. Despite my concerns about using this type of devices, it turned out that this 3D printer is easy to use and works perfectly in the work I do.
The 3D printer Elegoo Neptune 4 Max was provided to me by the Geekbuying store, link to 3d printer.
