Friends, all welcome.
If you live in a private home, or have a cottage, then, without a ladder in its economy will be very difficult. Of course, this is not a problem to buy ready-made ladder at the hardware store, but its price will be 2 times higher than the cost of the material, if the weld metal ladder himself.
stairs design of the profile, or the round pipe is very simple to cope with it even the person who does not have much experience tinkering something with their own hands. The only slight complication is a mark equal distance between the steps.
So we have 2 proftruby desired length to us, and the desired number of steps. How can we quickly and accurately mark the places of welding of these steps?
We catch the first and last steps, and then expose the smooth diagonal this design.
We know the total length of the frame poluchivscheysya (I mean that the limited first and the last step as though this frame), we also know the number of steps, together with the already stuck. Now add up the material along the width-dimension of steps on the front side of the stairs, and the total length of frame subtract this number.
In such constructions (I remember) the number of steps, and so on crossmembers. is always greater than one, than the number of distances between them. Knowing the number of steps, we take away from it once or it will be a number of distances between the steps, and now the number that came before (the length frame width minus all levels) simply divide the number of distances, and so we get the exact distance required to be between our steps.
I've been working on the welding repair of trucks and truck trailers, a lot had to do homemade boards of proftruby roughly a ladder structure with a small number of steps!
It was on board I adapted to mark up this quick and easy way to place welding of crossbars in the frame side, with all the stairs as well.
You can certainly mark the center of the stairs, first halfway down the stairs, then the center of half of the ladder, and so on. But to me this method centers breakdown did not really like it, longer, although considered a little easier!
If you master the manual arc welding alone, then add the channel to your favorites, so you do not seek, and you will have many useful articles for welding self-taught!
