Steve,
Reeving the lanyards is actually not difficult, but making sure the the deadeyes are level with each other is one part of what makes an outstanding rigging job. Again, this is a steep but short learning curve (thanks for emphasizing that Prof Tilley, Don and the rest). I again start on the starboard side and work fore to aft, lower to upper.
The first thing to do is strop all the lower deadeyes to the channels. Depending on the time period of your ship, this strop can be anything from actual chains, flat chain plates, one or two links long with a backing link connected to the hull, a straight rod with or without a backing link, to a flat metal bar. You can purchase these metal strops at numerous internet sites such as ModelExpo, BlueJacket and CastYourAnchor to name a few. Once those are completed you are ready to set up the upper deadeyes and shrouds.
You can set up the lanyard spacing by eye, which I have done at times, but personally I prefer to set up a spacing jig by using staples, both paper and staple gun size, that have a length a bit longer than the final spacing, this gives me some room to tighten the lanyards as needed. I then make it into an X by tying the center with thin wire. Now insert the shanks into the two bottom holes of the top deadeyes on the top and the two top holes on the bottom. You can temporarily secure the shroud with a slip knot at this point.
All the directions will be from the deck looking outboard. You always start the lanyard with the upper left hole, threading the lanyard from inside to outside. Tie a knot or two in the line that will hold it in place. Now take the line and thread it from the outside in on the lower left hole. Then up again and through the upper center hole and down through the lower center hole then up again to the right hole and finally down through the lower right hole. Now you want to tie off the lanyard above the upper deadeye with about three or four turns, knot and leave it for 24 hours. You do the same thing to the other deadeye of the pair.
Now you are ready for the port side. A good rule of thumb to remember is that the starting knot is always forward on the starboard side and aft on the port side. The reason I tell you to leave the reeving tied but not glued is because as you go along you want to make sure the mast stays in line. You wait 24 hours because it gives the rigging a chance to adjust itself.
Always remember to wax your lines, both standing and running. Most people run their line through a block of beeswax a couple of times and then run it through their fingers to even it out. I run my line through beeswax and then run it above a candle flame to really impregnate the line with wax. You wax your lines to help repel dust but it also keeps it looking taunt.
I still have a long way to go before I feel my rigging looks sharp, partly because I tend to be a bit of a perfectionist, and partly because I know with practice and asking for help, I will get better, just try and not get frustrated.
There are a great number of really fine ship modelers here willing to help out when asked, so use this vast store of knowledge and keep on building! Also, post pictures, we all like to look at what others are building.
One last tidbit, after about 30 minutes, take a break from rigging because you are probably cross eyed by then and always remember to have fun!
As always, I hope I helped and not hindered,
Steve
