One can use 'natural', but I still think it seems vey light - and may 'read' nearly white in photographs. Brand new full-size rope starts out on the light side, but it doesn't take long under use to darken into a medium tan. Builders can used their own judgement, as the whole point is to please oneself with any build.

Of course, it is white thread (the only kind I've seen), so the resultant scale rope will have to be dyed to the desired color. The classic linen fishing line was also white, but vintage examples are now slightly off-white. White rigging on model ships just doesn't look right anyway. Standing rigging should be either black or a very dark brown - that includes the lacing for the deadeyes and ratlines. Running rigging should be tan - but not too light or it looks "whitish" in photographs.

When using polyester thread, the scale rope made can have a tendency to unravel when cut. Baking (and note that this for a limited time at a moderate temperature 5 - 7 min at 300 deg. F ... to avoid melting) seems to 'set' the rope better and the raveling is far less. Cotton (or linen) scale rope can ravel also, but does not need heat setting. Cotton can weaken over decades, and that used on my Dad's clipper crumbled after 70 years. Heat, pollutants and UV exposure will affect this - as well as for many materials. No doubt, making scale rope from multiple cotton strands should be more durable - but linen is better a s natural material. The old-timers used linen fly fishing line (known as Old Cuttyhunk) and linen does stand the 'test of time' for rigging as well as sails. The indications are the Polyester scale rope will also hold up over the decades. BTW for either scale rope making or with full size rope (and I've demoed making some of that), one first spins the rope - and the trick is to balance the number of turns v/s counter turns in step one and step 2 of the process. If you've done that, the rope won't 'kink up' on itself. If nearly in balance, the rope will only kink slightly. The solution is to 'whip' the rope around so that it will get rid of any excess counter-twist. Then with one end fixed to something or restrained as convenient, you pull on the run (not too hard) to get the twist to meld to itself better. Stretching a few times will give a little more length and reduce the tendency to ravel when cut. The poly gets heat-set as noted above. Those who don't want to make their own can buy good scale rope from Syren or Ropes of Scale, as scale rope is far better than what is supplied in most kits. You'll notice that kit rope has a lot of 'fuzz' in close up shots. Poly has the least fuzz. Cotton rope will have some fuzz, but then what I've made from cotton has been QUICKLY passthrough a (relatively) low temp flame of an old-fashioned alcohol burner. This 'singes' off most of the fuzz, but if you don't move the scale rope fast enough - the line will catch fire and part. DON'T do this with polyester scale rope. Old linen fly fishing line doesn't have much fuzz because of the long fibers (cotton is short fibered), but it is VERY hard to find, since it was not made since the 1940s - and because some people collect spools of it, Old Cuttyhunk is very expensive. The rope size is also larger - for 1:48 scale models.

Your rig is similar to Syren's Rope Rocket - the videos on scale rope making on the Syren website are very instructive. The consensus is the Guterman poly sewing thread makes the best rope (oven 'set' 5 -7 minutes in a 300 degree F oven after winding and stretching), with Mettler a close second. I've used both, and the standard sewing thread has been available in sewing retailers (those that have not closed) or on line. Its best to buy in person to judge the color. The thread is aprox .006" in diameter, and using a single thread on the rig set up for three strand rope yields scale rope about .010 in diameter - that represents 1" rope at 1:100 scale (or thereabouts). Using 2 threads on each of the 3 strand setup (6 threads in all) yields scale rope about .020 in diameter. 3 treads on each of the 3 strands to wind (as I recall) yields closer to .030 scale rope. By experimenting (e.g. first making .010 rope and using THAT on each of a 3 strand set up - mind how the twist runs - can make thicker rope for larger scales). You get to control the product as needed.

Glad to have you aboard, mate! Johnny

'Lots to learn here. One tip from the home page - you can find MSW build logs (complete or not) for a specific ship (often from multiple kits brands) by hovering on Browse, then clicking forums, scrolling to and clicking the index of build logs (marked 'new') under Members Build Logs, then click the Quick Find indexes (the first listing). There you will find categories by year of launch of the ship you are looking for (you need to know the approximate year that ship was built). An alphabetical list will appear of the ship names, builder and kit supplier (if applicable). You can avoid many pitfalls by learning from those who have built these kits before.

Apparently things get a little complicated with paperwork and Canada's thresholds are different than those of the U.S. As far as Canada is concerned, they have what is referred to as CAD thresholds, which stands for "CAnadian Dollars" - so with the Canadian dollar now representing only about 73 U.S. cents, the CAD 150 threshold for Canadian duties would apply to courier shipments of a Model Expo kit exceeding $109.50 - and many kits are above that amount. However, "commercial" shipments are subject to a CAD 40, which is only $29.2 ... and it is not clear which limit may apply in the case of model Expo. But even goods now valued between the CAD 40 and CAD 150 points are STILL subject to: Goods and Services Tax (GST), Harmonized Sales Tax (HST), or Provincial Sales Tax (PST). Any kit now over $109.50 (CAD 150) is subject to BOTH duties, GST, HST and PST. 'Sound complicated? Trade deals are still in a state of flux, so it is no surprise that MANY companies are staying on the sidelines for now.

AN absolutely BRILLIANT idea for a builder who wants to make the detailed hull the star of the show ! Build her to the point pictured so far (or thereabouts) in your build and call her finished ! Such a model will be easier to case - or perhaps may not need a case ... just a little 'dust off' occasionally, and one can always have immediate access to the model. Transportation or moving won't be a problem, since the ship can be laid on its side over padding/bubblewrap in a box - and can even be safely shipped.

Planking bends amidships are generally gradual, with the greatest curves needed at the bow or stern. What I've done with pre-soaked planking needing more bend at the end is to put the end into my mouth ... Don't scoff, since perhaps there is something in saliva that helps the process - then I cautiously use my front teeth to slightly crimp the wood sequentially, with hand and tongue forming a tighter radius. One can 'feel' the fibers strain and just start to crack a little, which is the cue to back off. Its a bit of an art, but with some practice its worked for me. Different species of wood have a variety of tastes, but as with wine tasters, one does not swallow but rinses with water to cleanse the palette.

Wow, Kevin ... I watched #8 (planking) as a sample, and it covered in real time (mostly, except for some fast-forward sanding) fitting the first 3 plank pieces. The degree of design (including jigs and fixtures) is more impressive than first imagined, yet there is real craftsmanship in the 'fine tuning' of each piece for an exact fit - to be expected of a fine model. I noted the sparing application of white glue - most likely to avoid any irregularities when staining later on.
-
Yes, Kevin ! Thank you for the link. By applying the planks on the next phase to notched framing, everything should fit with only minor adjustments. The engineering in this Pavel kit is indeed remarkable. The Billings Roar Ege that I've done some preliminary fiddling with has a simple building jig with smooth, un-notched forms with only laser 'tick' marks where (presumably) the top edge of each plank should go. BUT, these marks are off (as well as the middle building bulkhead being not wide enough) - and builders typically have lapped planking trouble along the way. The frames to put in later just don't fit right as there are gaps, etc. The plank shapes appear to conform to published shapes of the originals, and I was able to determine where the 'tick' marks should go on the build frame bulkheads of the Roar Ege (the middle one remade to the correct width conforming to 1:25 cross sections - enlarged from the less than model scale provided with the kit). Still, having notched building frames would be better ... but would the actual notched ribs provide still fit after the planking is done? So I stopped work, at that point. I contrast this problem with the excellent approach the kit designers of the Woody Joe Khufu barge I did a build log on some time ago. There, they lasered the hull frames into the build bulkheads leaving small points of attachment. So after planking, those attachment points are cut with an X-Acto to release the hull frames from the building bulkhead - which took some care and fiddling, but the result was fine. So I'm thinking now that revised jig bulkheads might be fashioned for the Ege with recesses to receive the rib segments held by tape (for ease of later removal). Then the planking will be right on the ribs, so when the jig is removed everything will have a great fit.
-
This is amazing puzzle, with pre-fairing noted on frame pieces by a second lasered line within the perimeter. The building jigs are also engineered cleverly. I saw another build somewhere (but can't find it again just now) that goes meticulously through each step - with some useful tips/caveats. Other related builds of Billings Oseberg or Vikingskibbe have troubled themselves with installing riviets, yet Siggi's Gokstad recent build used a scribed line near the plank edge and pencil dots to simulate rivets effectively.

You're moving right along with the builds !

... 100% NH4 ? (Lab grade ammonia) That would be a powerful base and dangerous. Perhaps a 'full strength' household ammonia was used (a guess). In another build a triangular file was used to press a little into the back side of a plank to be bent to make a series of indents along the backside in the area to bend. (I can't locate the image right now.) I mean to experiment with this idea - and some water soak may assist.

You've done a fine job on the Baltimore !! ... and every builder is aware of any mis-step, or 'could have done better' on their own build. I printed the kit on 8 1/2 x 14" legal paper by using Photoshop to enlarge the images enough so the large pieces fit somewhat within the 14" limit, and will yield almost a 25" model (about 1:160 scale) when built over a future winter when current projects are finished. Of course, that made the width of the image go beyond the 8.5" width - necessitating splitting the image into 2 cropped versions that manage to get all the pieces intact on either one or the other. I'm hoping that the larger version will make some of the fiddly bits easier to make. - And your build offers everyone valuable guidance. Perhaps filling the voids between the bulkheads of the paper 'skeleton' with balsa will add much needed strength, heft, (and when shaped and sealed) something to form the paper 'skin' to with more limited wrinkling - especially in the upper stern area. other items can then be pinned right into the balsa as convenient. Thank you again for sharing, mate !!

Of course there are images that entered into the public domain from the moment they were offered for public sale with no claim of copyright - I'm talking about late 19th and early 20th century postcards with photographs or illustrations on the front side. Sometimes all they will say is something like 'printed in Germany'. Yet some individuals or corporate entities simply claim 'ownership' regardless - and multiple entities may be claiming ownership of the same postcard image! The only explanation provided by a friend (a published author) with some knowledge of copyrights is that individual examples of a postcard in the public domain will have unique defects and damage sustained over the years (like stains, creases, tears, postmark, spots, etc.) that comprise a virtual 'fingerprint' of that particular copy, thus making it unique. Thus someone may want to claim exclusive ownership of their own copy, This argument is nebulous, nevertheless one can take any public domain postcard image (whether 'claimed or not' - or any mage from an early 20th century copyrighted book that has entered into the public domain), alter it digitally (in Photoshop or other software) to 'erase' spots, repair creases and tears, change the coloration ... and then add your own special details to make it uniquely your own. Then whether you want to copy protect your own version of the image is yours to make.

My Dad built this kit before I was born, and I remember it being in the basement for a long time ... but no one can say whatever happened to it. Most likely he gave it to someone as a gift.
