Dux Rigging - Turnbuckles and or deadeyes

[alaskanviking]

Thank you for those pictures, very impressive. you reference bobbins however, ireally like the turnbuckles with the"bobbin"? at the top. while i suspect thier usefullness, i feel i am just shy of complete understanding. can you give a diagram of how one of those stays are put together? am i right in that these are "lashing bobbins"? and that they are used to connect to the tunbuckle to the end of the stay with a lashing but use the turnbuckle for tensioning? Do you have any pictures of one of these put together, or just the lashing portion? Please clarify.
