  1. Good evening,

     

    This is from earlier in this post;

    "The third photo shows the sail drying.  Once dry, the bolt rope and leach cringles need to be applied.  The cringles are where the rigging is attached to the sail.  The cringles are made by looping the bolt rope and putting a seizing to secure it.  The bolt rope is fixed to the edge of the sail with a product called "No Sew".  Basically, it is a glue.  The fourth photo shows the completed sail.  I didn't include the reef band or reef band because it would be completely hidden."

     

    and from a latter reply:

     

    "The bolt rope should be size 1 1/2" or 2".  The size of rope is circumference so divide 3.14 to get full size diameter.  On a prototype sail of the period, the head rope was a bit larger than the rest of the bolt rope.  For the model, you won't see the difference.   For the main sail, I went all around.  On square sails I usually leave off a short part of the rope on the sides to make furling easier as much of the rope is hidden anyway."  

     

    I estimated that the bolt rope on a sail this size on a small boat would be about 1-1/2 inch size.   Size of a rope is the circumference of a rope.  So, the diameter of the rope full size is 1.5/3.14 = 0.477.  Since the longboat is 1:24 scale, the model rope diameter is .019".  Using 0.018 is close enough.  I glued the line to the edge of the sail with full strength white glue or fabric glue as noted.  The key is that when you re-wet the sail that you do not wet the edges that the rope is glued to.  The glue will soften and un-bond if it gets wet and, I have had some come loose if I wasn't careful.  In full size practice to bolt rope is sewn to the edge of the sail, but in 1;24 the line would be very small to be in scale so I didn't sew it on.   On smaller scales I leave the sail edges wider and wrap the silk span around the rope. 

     

    I hope that this helps,

     

    Tom
