Greetings to our subscribers and visitors to the channel. We continue to publish a helpful article for those people who are masters of manual arc welding alone. And today, I will tell such an interesting topic, as a grinder to saw along a circular tube for exactly 2 parts.
For a visual example, I took a piece of old pipe 44, 250 mm long. Our task will consist in the fact that to cut the piece of pipe along smoothly into 2 parts.
The first thing we'll need a piece of any flat object, cardboard, wood, a piece of sheet metal, as I have in the photo. Its size should be several times larger than the pipe diameter, to be sawn.
On this plane, we draw a perpendicular intersecting lines 2 and the intersection of the center postpone all 4 sides the radii of our pipes and make notes on the photo shows that the distance between the opposing marks equal to the diameter of our tube.
Put the pipe end onto the sheet within the boundaries of selected radii. Put on the tube sheet may be optionally contrary, sheet attach a markup to the end-tube is not the point, to the main pipe was within markup.
And now make a mark on the pipe at one of intersecting lines, and on the opposite side end of the tube put the same mark on the same reference point (I think everything is quite clear).
And here he is, the ideal tool for marking a straight line along the pipe, this area, in this case, a piece of 25 corners. Area is very easy to put the marks on the round pipe-it will always lie flat on the pipe along.
Putting a corner to the label on the tube, and blue pencil, draw a straight line on a corner, also do the opposite mark on our pipe.
Since trumpet our short and light, in order to cut its Bulgarian we need to throw in the pipe from the more massive and heavy object, in this case proftruba.
Sawing, and obtain the required result. In the process of cutting, I led the drive strictly on the level.
Make a visual inspection and then to take the test more accurate angle measurements, and do our halves. One half of the pipe was less than the other by only 1 mm, it is a minor error.
Here's a simple method by which a novice, and not only be able to cut any round tube lengthwise into 2 equal parts!
And it is interesting that you can do from the halves of the pipe, go to our other statyu-Homemade of the halves PIPES
