Propeller shaftAre you referring to a torpedo tube or a propeller shaft ?
It's for a motorised model. Before the start of the war in my country, I bought ready-made solutions, but now this option is missing. I have an idea to implement it using sealed bearings with an outer diameter of 5 millimeters. But perhaps there are other options that are not so expensive and complicated.We would like to see what you’re trying to achieve. Is it for a motorised model or static display?
