Baldeagle,

These ferrules do always apear to be oval, since it is part of the assembly to press the two bracings between them.

The image above shows the ferrules before this was done. Therefore they look "still" round there. There is no need to produce them oval.

I have read about this procedure some years ago in one of the contemporary "Flugsport" periodicals, but do not remember which issue this was. When I locate it I will post it here including a translation.

This way to do it is still used today and can be found on sail planes up to the late 50ies early 60ties.

I must admit that I have not seen any note about how many turns it should have. I have seen such ferrules used with 5 turns and with 9 at one and the same plane. The Munich D.VII even has some of them left round in shape.
