Shrouds, Seizing's, Deadeyes, Strops and Chain plates for the Lower Mainmast
Seizing's go around a rope for security and to hold the ropes or strands of rope together as one

That is something else that is needed for the model. I found the thinnest line was some conventional thread used for repairs or dressmaking (raided my wife's sewing box). You don't need to worry about sagging of the thread as this is just used as a whip or wrapping.
Here's one of the ends of a shroud that will loop over the mast head for the lower mainmast.
Here is the actual seizing in progress. I found that a metal clamp is needed to hold the two ends of the rope together while I tie the seizing around. Its a bit fiddly, so its just a matter of trying to get a hold on it all so you can get the whipping / seizing in place. I found that about 8" of thread for each seizing worked pretty good.
Here I installed the shrouds for the lower mainmast to see what they would look like, and to get familiar with them.
Here's a closeup of the way the shrouds lay upon each other as they are alternately stacked from starboard to port sides. I have a picture lower down this thread that shows how it should be. Its basically the same as a full-size ship.
Now to finish building the rest of the lanyards for the lower mainmast shrouds. This tool I got works nice

I found it works for the 3mm, 4mm, and 5mm deadeyes beautifully. Its set to its lowest setting for this ship, although it will open up if required for other ships. This is the distance between the deadeyes. This is with the thinner rope 0.20mm. These have to be adjusted on the real ship so they can't be coated in tar so the rope is natural tan color.
Note that the lanyards are rigged differently on the port and starboard sides, as well as for how the rope has been made (right or left hand).
This one is ready for installation.
I found that the acid doesn't affect the other parts of the lanyard so it can all be dunked in the black patina liquid together



Just remember to rinse the parts well afterwards.
Another view of a shroud being clamped for being seized.
Before the shrouds are tensioned, it is best to install the mainstay so it prevents the mast from being pulled out of true. That would not be good


This is 1.5mm so its very strong!
An important point I found is to avoid gluing as much as possible which includes the masts, caps, tops, and shrouds. They really do not need to be glued as the rigging hold everything in place. It allows the caps to be removed to drop on the shroud loops and so on. It also allows for maintenance if needed later on down the line say if one of the masts got busted

The masts were never fixed on full size ships either I found out. They were not nailed or glued in place relying only on the weight of the masts, and supports from the ship to hold it.
So, the tops can be popped on and off as needed not requiring to be glued in place. It is essential to build as many assemblies off the ship as it is so much easier to do. Ideally, you should just be able to drop the parts in place with the least amount of worry for the rigging as possible. Otherwise too, it is easy to paint yourself into a corner if you don't.
The lanyards that go to the tops are a bit smaller at only 3mm in diameter as can be seen below.
These smaller lanyards all sit on the rail of the top. A different style of strop is needed for these and there is no word of this on the plans unfortunately.
The CA glue holds the lanyard in its shape when it pops off the jig.
Here I am making one of the strops needed for these lanyards. it is basically 26 gauge garden wire. They also need to be dipped in the black patina eventually before being installed on the top.
This shows how the lanyards should be rigged.
This is for an English ship and we are building a Dutch but there are some similarities, plus its a totally cool picture

The order of the shrouds after the top has been slipped into place.
Its always useful to have a look to see how they are on a real ship.
Another look at rigging lanyards I found online.
