I welcome everyone to the channel for self-taught beginners in welding and locksmiths. Here we share simple working tips so that self-taught garage-dachas don't have a long journey through trial and error, and their path to normal results becomes more interesting and cheaper!
A novice weekend welder cuts workpieces with a grinder for his own purposes. Cuts carefully along the markings. But as soon as he wants, for example, to cut a profile pipe with one cut, and not cut all 4 sides one by one, it turns out crookedly at the exit. Although he seemed to be holding the instrument straight.
After all, cutting a profile pipe in one pass will be many times faster, you want to do it so that it is even. Tries once, twice, three times, the result is not very good. He gives up this venture, and thinks that it will never be possible to keep the instrument exactly vertical. But this is quite possible if you know a couple of simple tricks that experienced locksmiths know. So.
Let's adjust the sight on our grinder! To keep the tool vertical to the surface of the metal to be cut, look at this. This is the relative position of the disc clamping nut and the edge of the grinder casing.
We make a rough estimate as follows. We put the square on the part, press the cutting disc against the square. We look in this position from above at the relative position of the clamping nut and the edge of the casing, remember or you can mark any mark on the nut or thread.
Now, in practice, let's see what and how, and if necessary, we will correct this relative position for a more accurate straight cut.
I marked the marks on the pipe, we will make a cut through them with one cut. We know the mutual position of the nut and the casing, we will keep it in this position. Mark out a few small pieces that we will cut off from the pipe.
After each cut, we look at the accuracy of the cut, and if it leads somewhere, we correct the position of the grinder's disk in one direction or another. We do this by slightly changing the relative position of the casing and the nut, which we are looking at from above.
And so we find this position in which our cuts will always be fairly straight. We now have better control over the instrument. I'll show you one more hint.
On the front on the casing we make a mark in the place where we have the disk. This will also be a kind of crosshair to keep the tool vertically relative to the metal being cut.
This scope comes in handy when you need to make any long cut in thick metal. When we cut along the markings, we just look along this mark on the casing. so that she looks exactly at the metal markings.
In this case, the disc will most likely run vertically. This means that this cut will not only be smooth, but also easier to hold the tool.
So these simple tips can greatly help beginners, and not just beginners. Having practiced on your instrument, it is good to see these elementary sights, the instrument will work much easier, faster, and the even cut by hand itself will give confidence in the further development of work with metal.
