Other option pipes are flexible: heat an aluminum tube that it became plastic, fill in in it water and freeze. When water freezes, bend a pipe.
Place a spring or a metalplastic tube that that was bent exactly in a pipe.
To bend an aluminum corner, heat it a torch and in some stages, gradually, bend.
For the qualitative are flexible a corner use the three-roller prokatochny machine or roll it on rollers where there is a board for a corner.
Exactly to bend aluminum sheet, take the cutting torch, for example, turned from a thin file and on the marked lines make wide cuts (pro-points) depth not less than a half from leaf thickness. Then accurately bend a leaf towards a flute - the line will turn out very equal. It is possible to make an incision a leaf also the Bulgarian - for this purpose limit depth of a cut and on the marked line exactly cut through a leaf.
If it is required to bend a small leaf (to 0,5 m), put back a bend a metal channel, a corner or a wooden bar, record and attract through it a leaf. Very accurately kiyanky for delicate works bend a leaf.
Bend sheets of the big size by means of listogibochny machines.
