What sort of diameter would an average degaussing cable around the hull of a ww2 battleship be?

Good question. I don't know. That said, there were and are many degaussing cable arrangements and many more of the related "deperming" system which serves the same purpose. It is quite likely that a variety of cable arrangements would vary from ship to ship and from location to location. (Of course, the "pole" of a ship's induced magnetic field has to be reversed as the ship travels from one hemisphere to the other in order to achieve the magnetic neutrality necessary to defeat detection by magnetic mines and so the configuration of the degaussing cables may have changed from hemisphere to hemisphere, as well. See: Degaussing — National Museum of the Royal New Zealand Navy (navymuseum.co.nz)

 

I'm going to guess and say that the cable was probably fairly substantial, but it's size and physical positioning would vary from vessel to vessel.

The Russians used 240mm cables, but electromagnets were also used to degausse ships.

What scale are you working in? Degaussing cables were generally at the waterline. Some went down the entire length of the vessel and others only part way. Some were ever moved around from time to time. Was that 240mm cable 240mm in diameter or circumference? There's a big difference between a nine inch diameter and a three inch diameter. That's a lotta copper either way!

It's 1/200, the anatomy of ships plans clearly shows the position and whole run around the hull. Ill post some pictures on this thread of some samples in the next few days and get some consensus

I thought as i was collecting samples the largest was going to be right, the second I put it against the hull it looked wrong so went down a size--still wrong the smallest looks just about right. Im still getting the hull filled and smoothed-

 

hope you think so too...0.8mm
