Angle 90°
To get a 90° angle, you need to bend the pipe and fix it in this position. To do this, you need to mark the center of the bend, that is, the future outer corner. Transverse parallels are drawn from the sides. From the bend point, oblique lines are drawn at angles of 45° in 2 directions.
From the side of the future inner corner, you need to connect the side lines. Then an indentation of 10-15 mm is made from the extreme ones to the right, and parallels are drawn. After this, you need to put a longitudinal line in the center between the two rightmost lines.
Using a grinder, a cut is made along the oblique side lines, then along all the facial lines, except for the leftmost one. You need to remove the cut out center. To do this, you will need to cut the pipe ribs from the sides to the leftmost line.
Next, a short longitudinal cut is made along the remaining mark, and the edges of the resulting antennae are unbent vertically.The left tongue also bends.
The pipe is then bent at 90°.
To fix it, the antennae are aligned back.
T-joint
To assemble a T-shaped mount, you need to make 2 eyes at the end of the pipe being connected. Their length should be 2 times greater than the cross-section of the second pipe.
In the second tube, cuts are made for the eyes so that they can pass through it.
Then they bend.
Parallel pipe splicing
To join 2 pipes together in parallel, 2 longitudinal cuts are made on them along the centers of two adjacent sides. Z
Then the blanks are joined by cutouts at the ends and pushed onto each other.
The result is a strong connection. This way you can combine pipes to make balusters, posts and other decorative load-bearing structures.
