How to get around a round pipe with a rectangular profile

How easy it is to cut and reliably connect a round and a profile and two profile pipes with your own hands

In the household, it is sometimes necessary to connect a profile pipe to a round one. Almost any adult can do such work with ordinary tools and some skill in handling them.

It will take

Materials:

  • a small piece of cardboard;
  • a piece of a round pipe;
  • three sections of a shaped pipe;
  • rivets.

Tools and fixtures: marker, scissors, metal ruler and square, angle grinder, vice, pliers, flat file, hammer, drill, riveter.

The process of connecting a profile pipe with a round

We install the round pipe with its end on the cardboard and draw a marker around its outer contour.

Cut out a circle with scissors along the markings in cardboard.

Fold the cut out cardboard circle in half. Make an incision along the fold line to the center of the circle. Bend the sector (1/4 of the circle) along the notch and cut it off from the circle.

We make a mark on the edge of the profile pipe, and on it we set the beginning of the arc of the cardboard sector and roll it along the edge of the pipe. Where the arc ends, we also make a mark.

We measure the distance between the points and find the middle between them, which we also mark. From it we draw two lines at 45 degrees on the side of the profile pipe.

Fold 3/4 of the cardboard circle so that the cut lines coincide in length. Cut the resulting shape along the fold line.

The beginning of the 3/4 circle arc is aligned with the point on the edge of the profile pipe, which marks the end of the 1/4 circle sweep, and the opposite radius with a line drawn at 45 degrees. Without changing the position of the sector 3/4 of the circle, we outline its arc with a marker.

We do the same from the beginning of the sweep of 1/4 of the circle and connect the points of the beginning and end of the sweep with a line.

We continue the exit of the lines drawn at 45 degrees along the narrow side of the profile pipe. From the points of their exit to the wide side, draw two lines at 45 degrees, from the point of intersection of which, on the narrow side, draw a vertical. Parallel to it, to the left and to the right, draw lines at a distance of half the arc of the circle of the sector 1/4 of the circle.

We repeat all the constructions made earlier on the other wide side of the profile pipe. Shading the surface of the pipe to be cut.

We carry out cutting with a grinder, removing individual fragments with pliers, and cleaning the edges along the perimeter of the cut.

We grasp the round pipe with a cutout in the profile pipe and bring the ends together first, so that the cutout tightly wraps around the round pipe, and the sides form a right angle.
