Thanks for the comments and, er "assurance" guys, it is appreciated. id simply hate to build the vessel so far and then, for only my own mistake, completely ruin it for the sake of a simple item ive overlooked.
Todays little project has been to create, er sorry, "construct" the roller fairleads , all 6 in total. these were measured up off the plans and the outer casings made from 1.5mm plasticard, so at least the casings should look "beefy" enough to withstand a cable load run through them. The rollers are simply measured lengths of hollow plastic rod, with some smaller silid plastic rod, run through them to act as the pivot bars.
i assembled the frames first, then allowed for the glue to dry fully before threading the rollers in to place, carefully dabbing some glue on the tips of the inner plastic rod, to still allow the rollers to rotate, as they would in real life.
I have now begun their painting, covering them completely in matt black, before adding some "wear marks" to the rollers before setting them in place on the deck. I am adding this wear detailling to these items as once glued to teh deck, I wont have full access to get the paintbrush in later.
the 4 "forward" mounted assemblies have additional angled support metalwaork to the rear faces, so these have been added in plasticard, of same thickness, the stern pair were made up of simple box construction, so the sit against the bulwark cleanly and dont have the extra back supports, the bulwark support brackets do that job as well.
