Joe,
I will try to explain.
1) First I cut a length of .75mm line that will be for a double shroud ( the line starts at one deadeye, goes to the Top (squared mast top), then back down to the next eye. It is considered a "pair" and not a single run.
2) OK, next, I will take the line in my case it might be about 600 - 700 mm.
3) with the line still in place wrapped around the Top, I will measure how far DOWN I want to serve. In this case, I wanted to serve about 30mm on each side (pair).
4) with the line still in place, and measured, I will take two alligator clips and mark the ends of where the serving will end.
5) remove the entire line.
6) the serving in this case would be about 80 mm in length
7) I used a .25mm line to serve with
8) I have a jig that I can old the main line in and I serve "between" the alligator clips.
9) seal off the ends with a very thin CA. (one drop)
More....
10) Now that the center of the main line is served, I have a square dowel that is same dimensions as the Top Squared Mast.
11) I wrap the line around the Square dowel as it would represent actually being on the model.
12) I used another piece of .25mm line to then serve the two (served) sections together---however, I only serve both of the (served) lines about 15mm as I want just enough to keep both together.
13) transfer the completed "pair" to the Mast Top and bring both ends (which both ends will be on the same side of the ship)
Now, here is where I am with the progress so far and I appreciate everyone following. I use a greyscale tone on some images as the colors can distract from details and it sort of gives a "magazine" look to it. Yes, it looks like the cannons will blow the lower stave off, but there is just enough clearance. Again, the design of kit puts very much limits on what you can do.
In the Panart Manual (pictures), I can't believe that they just show the shrouds as an UNSERVED line drapped across the tops with just one simple knot !!! Nothing in their kit manual even suggest or even show ANYTHING served. Pretty bad Panart !!!!
