A started cylinder of polyurethane foam dries up in a couple of months. It is impossible to squeeze polyurethane out of it, even after cleaning the tube. At the same time, a lot of liquid foam can still remain at the bottom. To extract it, you can make a simple device.

Materials:

  • Plexiglas 40-50 mm;
  • bolt М8;
  • M8 nuts – 2 pcs.;
  • worm clamps 70-90 mm – 2 pcs.;
  • old bicycle camera;
  • fumlenta.

Fixture manufacturing process

It is necessary to cut out a workpiece 40×40 mm from thick plexiglass.

After that, the plexiglass blank must be drilled through 2 more times to insert the clamps. The holes are made parallel to the adjacent thread. In this case, they must go to the side to the left and right.
