No comment needed Marc!
Your model, your choice Just as an FYI, from the The Elements and Practice of Naval Architecture the breast rail stantions on a 38 were 5" square not round and belaying pin handles were only about 2 inches in diameter so maybe not such a great match up to replace one with the other. Will you be adding the sheaves in the stantions as in the photo below? I think most folks are happy just drilling holes representing where the ropes will pass through the stantions, depending on the scale.I sawed off the heads and look at the result: much nicer in my opinion.
Iutar has answered and I am in total agreement. No line passed through a hole without a sheave that I can think of. BUT, like blocks, depending on the size and scale of a model, these are more often than not faked to just show you have two holes without the sheave. The sheaves were lignum vitae wood so if you just chisel out a little wood between the holes it will be very close in appearance to a sheave and once a line is passed through, barely noticeable. If you do add sheaves and use brass it would be best to blacken it rather than have a shiny metal sheave (unless you want to show off your detailing ) I just checked a bunch of contemporary plans and I cannot find any that show the sheave in the hulls. I am sure I have seen them in the past on some contemporary plans but I am guessing the draftsmen assumed everyone knew they were there so there was no need to draw them.In the instruction Caldercraft is mentioning to drill holes in the Hull for below mentioned functions
Dear Allan! I found this drawing, it might be interesting.I just checked a bunch of contemporary plans and I cannot find any that show the sheave in the hulls. I am sure I have seen them in the past on some contemporary plans but I am guessing the draftsmen assumed everyone knew they were there so there was no need to draw them.
