This craft is a bit more complicated than a carbon magnet, but simple enough to make it in a short time. With this device, pipes can be joined at right angles.
For crafts, you will need a corner, a strip of metal, a pair of long bushings and a thick steel wire. In order to connect all this correctly by welding, you will need a jig or other tool, a wire bend and a grinder.
The device works according to this principle: the first pipe is fixed with a neodymium magnet, and the second with wire loops, so that they are located at an angle of 90 ° for connection by a welding machine.
