I greet all the guests a channel, especially subscribers!
Quite a lot of welded products made from the corner of various sizes. This robust, thick-walled and durable material, rust will be a very long time, in our century will suffice!
Its pretty easy to weld, even for beginners, due to its considerable thickness and therefore on their site, or the country, the majority of products are made of metal and proftruby corner.
But before the welding work area, in most cases, it is not perfectly flat, especially beushnye corners, so they should always be brought to the direct state-peening (straightening).
That's me, the other day, an acquaintance dragged 5 of stems 45 and 50 corners, so I cooked him a pair of doors in the bulk-basement cellar. Of these, 5 were beushnyh whips 3.
Before marking, cutting and welding the corners, of course, it had to popryamit, as they were pretty curves, especially those 3 old corner.
The two parts of the curve was smooth, uniform arc, but one was the place where the curvature is subject to rapid changes, these boundaries sudden changes better mark marker-it's easier to see the place that you want to make the greatest effort when dressing corner.
And right corner best old-fashioned way, a simple tool for this purpose is called a stump! Just all these manipulations are best made on any large piece of wood.
And the rules we corner in a way, just take and tapped hump curve corner on the stump, it is this curvature hump. Knock first need is not much, and constantly visually monitor how hard the punches begin to correct the curvature, and that with such force gradually we correct the entire area.
Places marked with a marker, require priority fixes, these places are knocking more strongly until the correct curvature. But the area with a uniform curvature (arc), the following rules so close to the edges to knock to be stronger on the stump, but closer to the middle of the force is reduced. We do not hurry, constantly shoot eyes along the corner, and so give the area as much as direct state.
Also the old corners can be curved propeller. In this case, we insert somewhere, not to twist and unscrew it in the opposite direction to any similar tool for this. I pictured a special home-made instrument called karkalyga, monkey and so on.
That's all we have corrected and straightened curves corners, making these simple but rather laborious manipulation!
And now we mark up, sawing and welding box for our future doors.
