So, now an update - I have FINALLY finished the ratlines!!! I think I have said it before, this aspect of the standing rigging is a LONG job and takes a lot of time, but is quite rewarding and therapeutic. It is however worth doing well as the ratlines lie to the fore of all detail on the deck and within the ship - You have to look through them to see the detail, so they should be done well. In Post #213 I detailed the fitting of the shrouds and the futtock staves and these were all completed before I commenced the ratlines. I opted for a ratline vertical spacing of between 5-6mm which at scale corresponds to about 15-17 inches (360-450mm). From what I have read and in other forums, this seems to be about right. The ratlines were rarely 'straight' but usually had a bit of 'droop' so the separation is only a guide in any case.
There are MANY methods to get ratline spacing even and looking good. Some advocate the use of 'jigs' to separate and position the line both off the ship and on the ship, others use pre-drawn paper templates with the separation heights placed behind the shrouds and the lines tied in front. Others simply use a ruler, eye and lots of scrutiny. For me, after looking extensively, I find the best solution was that detailed in a couple of build logs by Kurt Suleski (alias
DARIVS ARCHITECTVS) who draws on his excellent build of
La Couronne. In his build he uses a build jig that maintains tension, keeps the ratlines evenly distributed vertically, and is relatively simple to construct and use. His description (with full credit to Kurt) is below:
"
To take the guesswork out of maintaining proper tension in ratline tying.
Take a look at my build log, starting at Post #188, and make the tool shown in Post #193 (see below). Glue strips of sandpaper or emery cloth to the inside gripping surfaces. The jig clamps onto the shrouds horizontally. Read the posts and you'll see how that ratline jig 1) holds the shrouds at their proper distances apart while you tie the ratlines with clove hitches, 2) spaces the ratline knots from the row you just tied below, and 3) acts as a straight edge that keeps the clove hitched on a nice, horizontal line. You can work on the port side shrouds, then use a ruler to match the heights of rows of ratlines relative to the bulwark, such that both sets of ratlines, port and starboard, match up in number, spacing, and height locations as you go. I grab the ruler and check the height of the ratline row I'm tying with the one on the opposite side every three rows or so. Everything will come out pretty even, and there is minimal knot position adjustment, which can suck up LOTS of your time. Tweaking is minimized. The secure each knot with a paint brush with diluted PVA glue. Each ratline section should be a tiny bit slack to look realistic, but if they are taut, that's okay as long as they are not too taut and pull the shrouds out of position."
The jig I built is almost identical to Kurt's and is shown below:
The width of the two timber 'bars' are 5mm and I have glued some emery paper inside to prevent the shroud lines from moving as you tie the knots. In EVERY case I have used CLOVE HITCH knots, even at the end shrouds and I have found them to be ideal for positioning (up down and where extra tension is needed or reduced). I have used some copper wire to hold one end of the two timber bars together and this applied enough pressure, along with two crocodile clips to stop the jig from moving while I tied the knots. As Kurt says, near the top, there is often insufficient room for the bar jig to be used and so the ratlines had to be tied by eye with a ruler to ensure vertical positioning.
Note that while I have been tying the ratlines for each mast section, if a futtock stave is required (which is all but the most top sections of masts and spritsail mast), this tended to hold the shrouds well separated and once tied, before applying dilute PVA white glue, I was able to 'eyeball' the ratlines and make sure that they were all parallel and evenly distributed. The clove hitch knots allowed some adjustment along the shrouds to make everything look even. I tended to leave every ratline row extending beyond the outer start and end shrouds until I had finished and applied the PVA glue. This ensured there was no unravelling or loosening of knots before I trimmed the ends off with a scalpel blade, taking care to cut away from the shroud lines.
One of the more interesting aspects of the alignment of the ratlines, relate to the angles of these relative to the deck and towards the tops, as these angle considerably, especially for the mizzen and main masts. I discuss this in Post #220 and compare the actual ship rake of ratlines with those from the DeAgostini and Artesania Latina Vasa models. I have largely adopted the angles as shown in the Vasamuseet Rigging Plans (which appear to also have been adopted by Billing Boats). For the foremast, the ratlines appear almost horizontal from deck level to tops. For main and mizzen the angle is raked to parallel the deck railings and then slightly increases in angle to the top as the tops for these masts rakes forward. As such, the ratline angle changes slightly as they go higher. It is an almost imperceptible increase in angle, but it has been done for my model.
