The more I look at it, the more I'm thinking we're actually looking at 2 things, with the darker object looking like a davit/ handrail or pipe and simply a white looking object behind it... By the angle of the picture their edges seem to coincide, but perhaps they aren't just object. The forward pipe? seems glossy, it seems to have a lighter spot on the forward upper edge, which seems like a reflection... Just saying...🧐

Now THAT is what I was talking about! Those pics (and explanation of bamboo) of the channel making process are gold! I assume you are using CA glue for this and not PVA? Thanks!

Well there, I was just about to say that all great things (or mazes) have small beginnings (or pipes), and that you made a good start of one, till Kurt mentioned that brace. That's how insanity starts... Before you know it, you're adding more pipes and supports... and there you go: a maze! What I was really going to say is that those details and pipes are what makes your build so excellent and realistic. Leave those pipes off and it may become bland and in some cases toy-like (although that still wouldn't be the case for your build). 👍

Hi Bill, I guess it depends largely on diameter. I also always go for full rods, not hollow tubes, since those will flatten in the bend. Full rods prevent bending. Second thing is radius of the turn in relation to rod diameter. I don't heat anything, since that indeed often goes wrong. In general I use drill bits to bend around and for small diameter rod, I do still use larger diameter bits. For example, a 1.5mm rod, I'd use a 4mm drill bit. This radius avoids extreme build up of matrial on one side and excessive stretch (and breakage) on the other side. I also always bend (for 90° bends) in several phases. I'll bend it first 50 or 60° and leave it for a few seconds (to settle, as the styrene is plastically deforming). I'll then continue further. It's a bit of feeling, how far you can go in that first bend. After that I'd typically bend it beyond 90°, perhaps up to 110° or so. It will return (remaining elastic deformation) to eventually settle around 90°. Once it has flowed this far, it is also easy to bend a bit back if that's required. Larger diameters are harder. For 3mm, I have a tube bender, but in Chaconia I also use white insulated electrical wire, where I use the copper core to insert into styrene tubing. I do this if large tubing has a lot of bends, where the lengths in between need to be accurate. In large rods bending such shapes with accurate distances in between is nearly impossible. I hope this is of any help. I believe there are a few pictures of the electrical wire trick in this topic, not sure about the tube bender...

That's a great job on that piping Keith. At such short distances, bending is indeed difficult. From time to time I use a piece of styrene with a hole of the same diameter as the wire near its edge instead of pliers. I then put the wire through the hole and bend by twisting the styrene piece or bend the wire while holding the styrene piece, depending on what I need. If the distance between bends is too small, you can still cut the styrene to remove the wire. It takes some practice, but once you get the hang of it... In any case, astonishing results so far. As to protections etc. they may have used portable fenders made of pieces of wood, hung overboard with a rope or even fenders made of old mooring ropes. Even today these methods are used on small workboats, apart from of course more professionally made inflated fenders or car/truck tyres.

That fork piece is a brilliant idea. Never thought about that! Please do make a lot of pictures of the build process,as I'm likely to check this log (and all your other logs) in detail for my next SIB.

Found some old pictures of my cotton wool thing. I did use larger pads of cotton wool, they were less dense. This was of course a smoke effect, I guess you will need to play a lot with the colouring to make it look like dense fire. Love the colours you've already applied, very strong pigment, and that's what you'll need I guess.

Thanks Paul, I must admit these overviews force me to take pictures from bigger distances due to her large size. A lot of her imperfections are therefore not visible on these pictures. I'd even go as far as saying I'm probably one of worst builders in this scratchbuilding part of this forum. I never quite succeed in getting things straight, always use too much glue and painting is mediocre at best. I have improved over the years, but I can not undo what I did 14 or more years ago. On her portside bow and foremast you also see damage from a collision with a bridge. Paint missing, mast severely damaged. I decided to treat that repair as a seperate project and first finish the ship. I wanted to mention that because for once it wasn't a construction or painting error by me. 😄 (it was a manoeuvring error by me though 😆) One advice for anybody building a ship this size is use of a movable table or at least a set-up that allows you to move around the model. You can't see it in the last picture, but the table feet are from Ikea and end in swiveling wheels (with brake). This allows me to turn and shift the model anyway I want and allows me to bring certain parts of the vessel closer to better lighting or powertools when required.

Incredible piece of work Keith. That dollar bill is really showing how brilliant this build is. Not only the building, but also the painting of such tiny pieces with such a sense of realism is simply outstanding!

Thanks, happy to hear someone might have a use for my posts. The jig was built 10+ years ago, I guess I was clever back then. The jig for the railing is however the 2nd version. The first one ended up being cut up and used in pieces in another build. I didn't really think of continuing this build I guess. In any case, the forward PS part of the ship is also finished. The ladders aren't glued though. In this top view you can see the railing on main deck that connects the catwalk stair with the stair to the foc'sle. I did have some time remaining, so I also built the 2 small stairs and 1 long one on the SB side of the catwalk (without railing or paint for now). And an overview:

Late to the party as ever. I've contemplated drilling holes in bottles for past projects, but always considered it cheating, just short of heresy. That said, and for the great purpose you have in mind, I fully approve of this hole and I'm glad you tested this because I was certainly curious whether it could be done without wasting a bottle. I love this project. Perhaps you could use cotton wool (perhaps coloured) around the leds to simulate fire? Should not be too difficult to get into the bottle as well. I have a cotton wool smoke trail of a missile that hasn't lost its shape in nearly 20 years and I didn't treat the wool with anything. Not really sure how it will spread or "contain" the light though...

First I finished that forecastle by adding the bosun store hatch and associated davit. For the davit handling rope I used normal orange sewing thread to replicate the commonly used orange polypropyle rope. The experience of actually finishing an area was quite addictive, so I decided to move just aft of the forecastle and finish that area first. Truly finishing it, also means creating the stairs, a task I'm not looking forward to. There is really a huge amount of stairs on this vessel and all are different. I was planning to leave them for last, but I believe this may have resulted in me not making them at all or ending up with a builder's block. So now on to the forward part of the deck, where I just installed the catwalk. First stair steps. I made a new jig for the steps. I already produced a lot of steps for the future as well. Then they go in the jig. And once we have a stair, I produce the handrails, also with a jig. This jig has both sides of the rails, but the length is not fixed. So I make the sharp end (upper)first, the check the required length with the stair. Then I mark it and form the blunt (lower) end of the rail. There are 4 long and 2 short stairs on the part in front of the deck house. Here is the forward most stair. You can also see part of the railing on deck level that goes from that stair to the forecastle stair. This is another part of the "safe acces to tanker bows" as required by regulations. And here is one of my secret weapons: I use a lot of these free paper measuring tapes from Ikea and other shops. Their flexibility comes in handy, from time to time I also cut them in smaller pieces for easier use.

She definately looks good. And what a pace of construction, from January start till finishing now! It takes some sacrifices to a model's quality to make it RC if you're not willing to continuously repair it. However on your model there are few visible compromises! What I don't like too much about such ships is the single prop/rudder configuration that limits the amount of manoeuvering one can do and increases the minimum required pond size to comfortably sail around.

I'm really short of time nowadays, so not much progress. Also wanted to add pics of the real ship, but having some hardware issues, so I'll just show some progress pics. Started by painting (and currently mounting) the forward catwalk. During the painting process I decided to finally continue that forecastle. First was the Chafing Chain. It's part of the obligatory Emergency Towing System of tankers. Small tankers only have one forward, larger ones also have a system aft. The forward system consists of a Smit Bracket (yellow thing in the pictures), with a chain connected. In an emergency, the chain is led overboard through the Panama fairlead by either the tanker's winches or the assisting tug's winch and then connected to the tug for emergency towing. Due to a chain's strength it survives the chafing of towing in heavy swell etc. Steel wires aren't so good for that and wires deteriorate much faster than chains. The heavy chain was connected to the bracket and stowed in a small coaming. On most ships it's also covered with canvas, but invariably it ends up as a pile of rust... I also still had the chain stoppers to do. They transfer the forces of the anchor and chain to the vessel structure rather than keeping it on the winch brake and/or gearbox. I've seen about as many versions as I've seen windlasses, so no real standard there. Generally it's a big block that's hinged between two shackles of the anchor chain with a counterweight to aid in removing it when the anchor is hoisted again. Once it's in place, the chain is lowered so that the next shackle rests on the stopper block (transfer of forces, windlass loses tension). I also finished the stairs to the forecastle, first stairs to be finished in over 5 years!

I may have missed something, but in the pictures, I only see black smoke being emitted from the main funnel. That would be the exhaust of coal being burned in the boiler. I do not see any white steam being emitted except from that small pipe in some pictures. That said, with such small space, placing a condenser etc. wouldn't be very practical. On the other side it would require a lot of fresh water stored in tanks... All in all, a very fine build! Love that subtle weathering, a difficult task at such scale.

Seem to have missed this. Glad to have been of any help on this build. She truly came out gorgeous! Despite your issues with the sails, I'm happy you went through and added them. The outcome has a great array of colours and contrasts. Although today they are generally engine powered, from time to time you still encounter some under sail in the Gulf.

Hi Brad, how much does she weigh at the moment? And I noticed decals on your air det, aren't you scared they'll come off in her wet environment? Or do you varnish the whole plane when they're finished? Overpowering a model is easy, but it's also necessary. Wind nor water scale down and nobody's going to make any mooring manoeuvers in an 11Bft gale... That said, seems like a fun boat to run. Not too large nor heavy.

Having much less power astern than forward is quite normal in real ships as well. Propellor shape and pitch are optimised to move ahead, not astern. The main reason a rudder manoeuver is always preferred over a telegraph one. The turning radius is always much shorter in advance than a straight stop. Also reversing props makes you lose any rudder effect/use. That's why sailing isn't as easy as it looks, you need to look well in advance. Real ships also have a lot less power available than any model. That said, I understand that on a pond a short stopping distance is preferred, certainly when other ships are involved.

With two identical props you will have a stronger propellor effect when reversing. With counterrotating ones this balances out. Depending if you go for right or left handed props, the bow will very strongly move to either port or starboard side when reversing. Which then means that whenever you'd want to reduce speed, you need to take into account a heading change and turning of the vessel. Rudders don't work when props run backwards, so you can't compensate for it either. That's the only disadvantage I can think of. Perhaps also vibrations that will increase instead of cancelling each other out, but that's difficult to predict. She's looking sharp!

And time for an overview: next steps: - fix some issues with the piping edges at the forward edge of the hatch and piping issues forward of that edge - level out forward catwalk since it determines the height of the next part along the deckhouse - complete the piping connections to the deck house - finish and fix catwalk next to deck house - finish forward edge of manifold catwalk where it makes a step to the part next to the deck house I believe after that that I will proceed with finishing the deckhouse (finally put the real crane jib support in place instead of an airbrush jar) and railings on top of it. And together with that, start making the stairs to the catwalks. Only the aft catwalk is glued, all others are just dry fitted. I will first put some transverse beams, paint those and also the catwalks themselves before gluing them, same sequence as I used on the aft part.

I did not have much time in the last couple of months, but did manage to do more than anticipated the last two weeks. I haven't made any updates since it's simply more of the same... I finished the forward part of the catwalk, including railing. Currently working on the railing of the manifold part and simultaneously building the last part of the catwalk, the part around the deckhouse. As you can see, the Legos have made an entry for keeping things in place and straight. Picked up that trick over here. Of course I need to be carefull since I'm using glue for styrene, so I don't want to glue the blocks to the catwalks...

For what it's worth, the bearing device is called a pelorus. The stand itself is called a binnacle or compass/gyro repeater. I'm however not certain if in that time they actually had repeaters or if it was a fixed rose that would give relative bearings (relative to ship's bow that is) rather than compass bearings. Nowadays we take gyro bearings with these things. Sorry for interrupting. You're doing an excellent job. Quite an improvement over your original version!
