I take an electrode cinder, make a couple of measurements at the end of the round pipes. With this piece of electrode I make markings on the pipes, I saw with a grinder along the markings, and now I get a joint of 2 pipes at the angle I need. Now I will tell you in detail about this primitive garage method.
2 pieces of round pipe with a diameter of 42 mm. We make flat ends at 90 degrees. We need to join these pipes at the angle we need. We do not know how much it is in degrees, we just connect them with their ends in the position that we generally need.
Where the ends are tightly connected, we put a welding tack. We will additionally fasten these with a pipe through a tack of some piece of iron to them. So the overall structure will be rigid and convenient to work with for marking.
To check this angle later, I grabbed 2 pieces of corners along the edges of our pipe structure. When we mark and cut off the excess with a grinder, we will put the pipes in these corners and see what kind of joint is. Now we make the necessary measurements.
We measure this distance between the outer ends of the pipes in the structure. It turned out 65 mm. We remember or write down.
We take an electrode or an electrode cinder. Gently beat off the coating, do not knock hard, so as not to bend it. Cut off a rod 65 mm long, the same size as the distance between the ends.
We also need a size for which, if you mentally continue the pipes before joining, they will converge at one point. With two squares I measured that distance and got the number 53 mm. We remember or write down.
From the butt end with a tack, lay 53 mm on the pipe. We put a vertical line. The diameter of the pipe is 42 mm, from the surface where the pipe lies, we set aside half of the diameter-21 mm and set a horizontal mark. Also on the second pipe. we get two crosses. The distance between them is equal to the distance between the outer ends of the pipes.
And also equal to the size of the electrode rod that we made - 65 mm. Who guessed what would happen next?
We put the rod with its ends on these crosses and begin to gently roll it up. In the direction of movement, we put points where the ends pass through the pipes. Then we will connect these points into a solid one.
We connect all the points into a solid line. In front of the pipe ends, the rod does not touch the surface. There we will neatly round this markup. Strongly not mistaken!
We take a grinder, cut off all the potholders and saw along the markings.
We lay 2 pipes back into the corners-borders of the corner we need and see what kind of joint turned out. Everything worked out pretty well. The gaps are small, there are a couple of places with gaps in the rod thickness of 3 mm. It's a little for welding.
Such a simple and primitive method will always help you out if you need to make pipe joining at an angle. No complicated calculations. Take your locksmith tricks into your arsenal!
A video of this marking process will be released on the channel tomorrow, December 1st, in winter!
