For the manufacture of heat-shrinkable PET tape required strand. Such a tool can be done based on the steel area, and this will allow you to get a tape of different widths.
- area 20×20 mm;
- the blade of the knife mounting;
- screw type M4;
- washer M4;
- nut M4;
- stud M4.
The process of making strand
From the corner to sober up a piece of 150 mm.
Then at 80, 90 and 100 mm need to make cuts on the edge of the area to a depth of 15, 10 and 5 mm. Cutting is performed by a hacksaw.
Next you need to apply from the inside corner of the mounting blade of a knife and fix it.
This must be drilled in area 2 and cut holes in them, thread M4.
One of them should be next to the standard holes in the blade, and the second a little beyond the tip. This will allow to hold on the area the blade cutting edge to the slits through the hole with the screw with washer.
The second hole in the area from the tip of the blade is screwed into the stud with a length of 250 mm. It is fixed in one position with the nut.
For obtaining strips from a plastic bottle cut off the bottom.
Next, the strand is clamped in the vise vertically, slightly below the studs. A plastic bottle is put on the pin and the lower edge cuts into one of the slots on the edge of the area.
Turning it around, you need to achieve out to cut the ribbon on the other side of the cut. Then pulling already it is possible to dissolve the whole bottle.
Depending on which slot tucked the bottle will be able to obtain tape widths of 5, 10 or 15 mm.
Where to apply this tape?
This strip from the bottle has incredible strength and has heat shrink properties. Is to wrap it in, say, two pieces of wood, tie a knot.
Next, heat with a hair dryer or a lighter.
And now, just because these blanks do not disconnect.
They are pressed firmly to each other and not even swaying.
Where to use this knowledge, only you can decide. all the while.
