Smoother running of the Piteba oil expeller
The Piteba oil expeller runs smoother when a leather washer is mounted on either side of the metal washer. This prevents wear on the washer.
Below is a description:
- Take a smooth piece of leather of approx. 1 mm thickness.
- Cut out two rings with a maximum diameter of 28 mm and a hole of 14 mm.
- You can also make two hole punches from pipes of suitable diameter to which a sharp edge is ground (see bottom picture).
- Slide the washers onto the expeller screw with the metal washer in between.
