Dear fellow modellers,
I have posted this thread to share my experience with building small ship mounted vents.
These are the type of vents that include two parts: a tube and an intake.
The construction method I present is a mix of tips I took from the forum and the experience and skills I developed while building the large number of vents for the Kaiser Wilhelm der Grosse model.
I have chosen to write in English to make this thread widely available. Apart from that I think the pictures are largely self explanatory.
