  1. hi . its now time to start the build log for the us coast guard cable steam boat. a wil write more soon how its going to be built ! here ate some photos of the frame for now! svein erik
  2. S.M.S. WESPE (HENK, 1895) History and context The WESPE-Class armoured gun-boats of the then young Imperial German Navy were born out of a tactical concept that dated well back into the Napoleonic era. The idea was to mount a heavy long-range gun onto a highly mobile small craft that would be able to retire into shallow coastal waters, beyond the range of even the heavy artillery of an attacking fleet. The addition of a steam engine and the increase in calibre followed the development of the time, of course. Adding heavy armour to the front (mainly) was meant to give the gun-boats a certain attacking capability. It also owes something to the floating batteries used in the defence of Copenhagen during the Napoleonic wars and to the armoured floating batteries used by the allied French/British forces during the Crimean War (1854-55). In fact, adding armour plating to a (rowing) gunboat was already proposed as early as the late 18th century in Spain, as documented by a model in the Museo Naval in Madrid, but apparently never put to work in full scale. S.M.S. WESPE, brand-new and still without the 30.5 cm gun (1875) At the time of the conception of the WESPE-class in the early 1870s a former cavalry(!) general was the naval chief-of-staff in Germany. The tactical dogma was ‘proactive defence’: an attacking enemy was to be awaited near home waters and fenced off. The main threat was seen in amphibian operations attacking the German coast. Thus, the landing of troops at strategic points had to be prevented. Long-range strategic and oceanic operations were out of the scope of the German naval planners of the time. There was a certain logic in this, as Germany, unlike Britain, is/was a more or less land-locked country and largely self-sufficient in many respects at that time. Overseas trade then did not have such an importance as in Britain or as in later globalising economies. Therefore, attempts to severe overseas supply chains was not so relevant. There was, indeed, active resistance from trade interest groups, particularly the merchants in the cities of Hamburg and Bremen, to a navy that would engage itself overseas. These merchants relied on their network of friendly contacts and on sailing under a neutral flag. Hence, the WESPE-Class was designed to be mainly a heavily armoured gun-platform, giving long-range protection to the tidal North Sea harbours that are surrounded by mud-flats and to give mobile protection to the deep fjords of Schleswig-Holstein's Baltic coast. They would be backed-up by heavy artillery (and later fixed torpedo batteries) in coastal forts. The guns in such boats usually could only be trained by turning the whole boat. This seems more difficult then it probably was, because even in the old days of the rowing gunboats they would attack by rowing in a wide circle and when the intended target passed through the line of aim, one would fire. As the WESPE-Class was designed to let themselves fall dry on mud-flats, a possibility to train the gun itself was needed. This distinguished the WESPE-class from earlier boats of similar design in Britain, namely the ANT-, GADFLY-, and BOUNCER-class of the 1860s. Man other navies took up the same concept and there were examples in the Danish, Dutch, French, Norwegian, Spanish, and even the Argentinian navy. Some of the were armoured, while other were still constructed from wood or composite. S.M.S. WESPE under construction (HENK, 1895) Technical Description The WESPE-class comprised ten boats delivered in two batches between 1876 and 1880: WESPE (1876), VIPER, BIENE, MÜCKE, SCORPION, BASILISK, CAMAELEON, CROCODILL, SALAMANDER and NATTER. They were all built by A.G. Weser in Bremen. With a length of 46.4 m and a beam of 10.65 m they had a dead weight of 1157 t, drawing 3.37 m. The dimensions vary somewhat according to source, but this may be due to different reference points, such as length overall compared to length between the perpendicles etc. Two inclined double-expansion engines on two propellers gave a maximum speed of 11 knots. Their original complement was 3 officers and 73 crew. Steering was from a stand on the hut and an emergency double steering wheel abaft. Very early on they were also retrofitted with an electrical generator. The WESPE-class were the first German warships (and indeed among the first of any warship) that did completely without auxiliary sails. As the consequence they only had a light mast for signalling. In spite of sporting quite some leading edge technology, they were only of limited seaworthiness and their handling was far from perfect. This resulted in them being given a collection of rather unfavourable nicknames. They were also not very popular with their crews and officers due to the cramped conditions below decks, but then they were not meant for long voyages in the open sea. Admiralty illustrative drawing (before 1883) Armament The main armament was a single 30.5 cm rifled breech-loading gun designed and manufactured by Alfred Krupp AG in Essen. At the time the WESPE-class boats were designed, fast torpedo-boats did not exist yet – the automotive fish-torpedo was just being developed. When in the mid-1880s small torpedo-boats became a tactical reality, some form of self-defence against them was necessary and two bronce(!) 8.7 cm/l24 breech-loading guns in ‘disappearing’ carriage and two 37 mm Hotchkiss revolving guns came on board. In fact, very early on (1883) also two 35 cm underwater torpedo launching tubes were installed to increase the attacking capabilities. Instruction model for the Rk 30.5/l22 on the Danish HELGOLAND in the Orlogsmuseet Copenhagen on a carriage similar to that of the WESPE-Class Scale The scale chosen for the model is 1/160, which admittedly is somewhat unusual for a ship model. However, the reasoning behind this choice was that a large selection of N-scale railway figures is available that eventually will crew the ship. There are also space and portability consideration, which are important for someone, who has to move from time to time for professional reasons. The model will be a waterline model. This will allow a scenic presentation of the finished model. Besides, the hull below the waterline is not quite so graceful. Above the waterline the hull is also more or less prismatic, with vertical bulwarks and virtually no sheer. These parameters together call for a bread-and-butter construction. Artist’s impression of a WESPE-Class gunboat (1891) Sources Owing to the loss of most of the archival material from the former Admiralty Drawing Office during and after the end of WW2, detailed source material is rather scant. Some lithographed drawings that must have been made before the major refit in 1883 have survived and serve as a basis for the reconstruction. The Bundesarchiv/Militärarchiv in Freiburg i.B. has some drawings, but unfortunatelly they only pertain to a much later refit of S.M.S. NATTER. However, the WESPE-Class was a bit of a novelty at its time and some Detaildrawings of bothm the ship and the armament, have found their way into textbooks of the time. Relatively recently a very detailed original drawing of the gun became available on the Internet from a private collection (www.dreadnoughtproject.org). Historic photographs from the early days of the ships are quite rare and mostly of not so good quality, but some reasonably good ones from the end of their active life have survived. Based on the information that was available in the 1980s Wolfgang Bohlayer drew and published a plan of S.M.S. WESPE as she might have looked like after the major refit in 1883 (available from VTH, http://shop.vth.de/wespe-1876.html). Based on the information available today, this plan would need to be revised in some details. The available information is summarised on the page on the WESPE-class on my Web-site: http://www.wefalck.eu/mm/maritime/models/wespe/wespeclass.html To be continued ...
  3. My new project is a steam yacht from 1884. It's Loreley. The drawings are made by myself which I shared some time ago in this forum.
  4. Hi folks, the new project. I am not the sole builder of this model which is a club project for the Ship Modelling Society of Victoria. I am coordinating the build, doing the research, drawing the plans and assisting in the build process. I am providing this log as she is an interesting ship and I thought members may be interested. While designed as a warship along the lines of the contemporary Arrow and Vigilant Classes of Gun Dispatch vessels, she was operated in various roles, with only a very short period of active duty as a commissioned ship during the Maori Wars in New Zealand. Her Majesty’s Colonial Screw Sloop (HMCSS) Victoria was built for the defence of the Colony of Victoria during the gold rush era. The above image is a copy of a purchased image from The Illustrated London News which shows her during her Builders Trials. Additionally, as much of the hull construction has already been completed, I will providea summary of this part of the build only. Some questions related to researching this ship have been asked previously in other forums (see following links): http://modelshipworld.com/index.php/topic/5574-cat-head-dimensions/?hl=%2Bhmcss+%2Bvictoria http://modelshipworld.com/index.php/topic/3754-rigmaiden-patented-lanyard-plates/?hl=%2Bhmcss+%2Bvictoria http://modelshipworld.com/index.php/topic/3780-emergency-tiller-for-hmcss-victoria-question/?hl=%2Bhmcss+%2Bvictoria
  5. The Hatton and Hart photographs were/are my primary source for trying to create as much model authenticity as possible. Sometimes I have to assume, which I hate. Example being, on the upper stern deck a partial funnel profile can be seen behind and to the port side of a binnacle. (I may as well jump on this grenade while I'm here. This binnacle appears to be about five and a half feet tall, a foot and a half above the standard four feet. Access to viewing the compass is aided by a two step ladder propped up against it seen in the first of the four H&H photos.. I'm guessing the reason for the extra height is where the compass is above the railing and other metal objects. Please jump in with comments should you have other thoughts) All other photographs from the starboard point of view are and blurred and of no use determining if a starboard funnel is actually there. I chose one to be there due to ship designers seemingly love of and necessity for symmetry.
  6. As I wrote here http://modelshipworld.com/index.php/topic/11538-western-river-steamboat-heroine-by-ggrieco-scale-124-1838-as-she-appeared-before-hitting-a-snag-in-the-red-river/?p=401974I plan to build the USS Cairo, as all my modelships in 1:50 scale. The history of the ship is well known, there are so many pages in the internet, so I will not bore you with that. But there is a big question I have. I have a set of the plans from bob hill, and I am not sure, where to measure the length of the ship. Is the lenght of 175 feet measured at the hull, or includes this the rudders between the blue lines on the plan? I have marked the lines with red arrows. Would be happy to get some info about that, so I can scale the plans and start with the ship. Regards, and thank you all Gerhard
  7. Ok. Am starting this log because I have deside to build this steam cutter , am still working on the plans , in 1:48 scale this ship vil be about 105 cm long and about 20 cm wide the hull wil be made of wood and planking , the orginal is steel but I wil use silver tape for the steel plating with nails. there wil also be alot of metal sheets to soldering . for now I orderd the book, us.coast guard and revenue cutters 1790-1935.by Donald L.Canney and orded som birchwood plywood for the frame (6mm) Here is the first photo of my big prodjekt Svein.erik
  8. Hi all well since my kit building seems to be getting very shabby i thought maybe going back to scratch building may get them back on track I had a choice of plans to pick from and I narrowed it down to 3 possible I eliminated the St Louis Belle as I want a fairly quick build not a three yr jobbie also I eliminated the Kitty as it was a little too simple so I opted for the WC Normally I like to build large scratch builds but due to space I'm reducing this by 50% First problem is that the keel at the reduced size is very flimsy so I've changed the plan a bit to give some strength.
  9. Introduction : This project has been completed already in the years 1984 / 1985, when I was still a young man. I had the intension of building my own designed steam engine for a model ship. A regular steam engine with crosshead-guides and Stephenson reversing control device, was too complicated to build, in lack of neighther lathe nor milling machine (still do`nt have….). So I decided to design a steam-motor with a minimum on moving parts, and yet powerful enough to propell an appr. 1100 mm long RC controlled ship model. And the driving challenge was also to see if I could do it anyway…… Current status : After some years of perfect performance, the boiler became a hair crack leakage in one or two of the inner heating tubes solderings, that unfortunately could not be mended without destroying the boiler. So neighther ship nor motor had been moved since. I wanted to rotate the motor the other day by trying to rotate the crankshaft but all was blocked somewhere, probably the pistons are sticking to the cylinder walls. Shall have to dismantle everything completely for overhaul, and build a new boiler if I want to have fun on that behalf again. Fortunately the was a raghther short little super 8 Kodak film made of the model travelling on the lake at full steam in those wayback years, the film in miserable quality, but at least a document of a successfully completed project. I`ll try to put that film in a little video here on MSW in this log later on. Some of the pictures I found fortunately in my photo-archive and scaned them in, and was myself surprised that I even had pics of motor complete, and boiler in the building stage. I thought this may be of interest for the one or other fellow builder here at MSW. The ship itself is still ready to be launched at any time, only the prop has a bit patina on it The ship Model-length 1090 mm Steam powered, gas fired, RC controlled, fictional version river tug “Lorbas” in nostalgic look Model Build year : 1984 / 1985 Ship is POB scratch design, self drawn lines, ply frames and diagonal planked with balsa stripes, Hull coated with glass-fibre rowing cloth and epoxy resin Removable deck housings and many maintenance opening hatches and doors, and ventillation openings for the boiler- and machine room large self made 80 mm 4-blade brass propeller RC control Simple oldtimer 2-channel radio-controller, Make “Robbe” and on the ship two-channel receiver and two servos (one for steam reverse valve, stop, foreward, aft) one for rudder port / stb. One power pack comprising 4 x 1,5 V mignon Batteries. I`m not allowed to use this RC equipment any more due to national postal radio frequency regulations The Engine Self designed Six cylinder Steam motor in Vee-6 design, for superheated steamflow, with direct piston rods to crankshaft, ball bearing crankrod head-bearings, each cylinderhead with common, horizontal working slide cam control bars, manifolds for steam inlet and steam outlet (reversible) Steam reverse valve (for swapping inlet / outlet channels with RC servo function. Motor designed for 2 bar constant steam backpressure when running at 200 RPM in direct (quick disconnectable) coupling to propshaft Idle unbreaked motor runs up to 3000 RPM, if control cam positions are set correct Model speed like modest walking pedestrian Lubrication by means of oiler-device in live steam line (high viscosity steam engine oil) Piston rings made of Teflon in circumferential pistenring grooves Manifold gaskets made from Viton O-rings (heat resistant) Elbow- and t-fittings and flanges silver soldered, tubes soft soldered in Materials: brass and stainless steel and commercial available bearings Six Cylinders 10 mm diam. X 10 mm strokelength Due to the six cylinder arrangement the motor is capable of starting rotation at any crank position The boiler It was my aim to create a powerful lightweight design for firing with butan gas burner and gas from commercial, exchangeable cylindrical cartridges that fit into the boat (like used for refueling cigarette lighters). Function: The boiler has one central flame-tube cross-spicked through with 6 smaller instant steam tubes that mount into the area of the upper steam collector dome. The hot gas of the flametube then reverses direction in the outer end-camber, that also contains the superheater tube coil and from there 13 heating air tubes lead back through the boiler, into the opposite chamber that takes up the chimney tube (inner liner of the ships funnel) The waste steam tube is connected to the inner chimney liner in order to burn out the micro-oil-fume of the exhaust steam in the upstreaming hot air together with the firing exhaust. (avoid lakewater pollution !) The safe running time with one distilled boiler-water filling is 20 minutes The boiler is capable of providing constantly 2 bar backpressure at ships full speed The boiler is equipped with a stand, wooden plank cladding, a blow off safety valve, a pressure gauge, a main steam valve, an oiling device, a water level indicator, a draining point, and a heat exchanger for pre-heating the expanding butan gas from the gas cartridge The boiler is mounted to a common aluminium baseplate that also takes up the motor mounting bracket and the burner mounting bracket. To fire up the boiler, the flame tube is heated with a external (more powerful) gas tourch outside the ship. When reaching 2 bar steam pressure the complete baseplate is set into the ship from above Materials: Boiler complete from stainless steel, silver soldered, pressure tested with 4 bar Enjoy...... Nils
  10. Some time ago I promised my wife to make for her a ship in a bottle larger sizes than previously made. I begin to fulfill a promise - it will the model of the steam schooner with the glorious history and the symbolic name "LENA". History: The wind power meets the power of steam in late 1800’s . In this period of maritime history, a hybrid generation of ships appeared combining these two. They kept the glory of sail ships and added independency from wind. Lena is a little steam schooner like that. She was launched in 1875 in Sweden by Motala. She was 26.8m long, 4.95m wide and 2.59m deep. While sailing by wind, the funnel tilts back so that the sail boom can move freely. She has an interesting story beginning with Nils Adolf Erik Nordenskiöld’s polar expedition. She joined the expedition as an auxiliary ship up to a point. She took part in Russian revolutions. She was reconstructed several times. Once in 1938. She was extended two meters in length, a new boiler was installed and living quarters were rebuilt. In 1959, she was planned to be reserved as a historical vessel. But the attempts failed in 1967, the damage she suffered was beyond repair. But the model ship builders will help her to live forever. - by Captain from Free Ship Plans Best REgards! Igor.
  11. For those of you who have been directed here from my Armenia build in the ‘Build Logs for SCRATCH SHIP MODEL PROJECTS’, please bear with me. For those of you not coming from that build link I will be developing a 3-D model of the Hudson River sidewheeler, Armenia. Briefly, the Armenia (1847-1886) was built by Thomas Collyer, New York. She had a wood hull with an overall length of 187 feet, a molded beam of 28 feet with an extreme beam of 50 feet with a depth of 8 feet 6 inches. She displaced 391 tons. She was powered by a Henry Dunham vertical (walking) beam engine. The paddlewheels are 29 feet 4 inches in diameter by 8 feet 3 inch wide. I will be following drawings, by F. Van Loon Ryder dated 1954, 1/8” (1:96) scale, resized to 3/16” scale. The purpose of building this model is to help me better understand how to actually physically build this model from scratch and to learn 3-D cad. I will be building this model with AutoCAD version 2013. I’ve used AutoCAD for close to 30 years now but never its 3-D functions. This will be my first attempt at a 3-D model so all you proficient users of 3-D cad, if you see me doing something really stupid please don’t hesitate to let me know. That goes for all you steamboat experts also, as this is my first steam powered boat, if you notice that I am making some major faux pas on the ship please let me know. Alright enough talk lets draw something. I started by scanning the hard copy of the drawings and making .tiff files of them. Those files were then inserted into AutoCAD and scaled to 3/16” (1:64) scale. Using the Body Line drawing I laid the keel using a polyline and sweep command. Next I used polylines to trace over the body line cross sections. From these tracings I extruded the bulkheads needed to form the hull. A little a## backwards with this next step but using the bulkheads I formed the bulkhead former. Slots were made in each bulkhead with matching ones in the bulkhead former. These pieces will be used as templates to construct the actual model. Once all the bulkheads and the bulkhead former (BF) were completed I used the ‘loff’ command between each bulkhead to create the hull. OMG, if real planking could be this easy. Hull complete.
  12. Hello all. This is my third build log here on MSW and will be my first attempt at scratch building a ship. The ship that I will be trying to build is a Hudson River sidewheeler named the Armenia. I acquired plans for this vessel through my local model club (Connecticut Marine Model Society) and there are two main reasons I decided to build her. First I found the ‘walking beam engine’ that drives her paddlewheels to be a fascinating piece of machinery; the second and maybe the more important is that the admiral likes her too. The original plans, by F. Van Loon Ryder dated 1954, are drawn at 1/8” (1:96) scale. There are four drawings detailing the ships profile, body lines, the engine, and different deck layouts and one sheet of technical specifications. The Armenia (1847-1886) was built by Thomas Collyer, New York. She had a wood hull; length 185 feet on deck, 187 feet overall; 28 feet molded beam, 50 feet extreme beam; depth 8 feet 6 inches; 391 tons. She was powered by a Henry Dunham vertical (walking) beam engine and had an unusually long stroke of 14 feet. The paddlewheels are 29 feet 4 inches in diameter an 8 feet 3 inch wide, turning at 23 rpm. In 1852 the Armenia was lengthened to 212 feet, increasing tonnage to 421; cylinder diameter increased to 42 inches; a second boiler added with second stack aft of the original stack and the typical guard posts and hog framing added. I will be modeling her original configuration. Since this is my first scratch build I’ve been a bit hesitant in starting her mainly because I wasn’t too sure of what material to use and how much of it I needed. After hemming and yawing for a few months I decided to do what I’ve done for the past 40 years and that’s to make my own drawings of the ship so I’d have a better understanding of just how she was built. I’ve only done building (structural) drawings but I think with the set of original drawings and a little help from the CMMC members and the people on this site I should be alright. For my set of drawings I decided to redraw them at 3/16” (1:64) scale instead of the original 1/8” scale. I thought it might be a little easier to build a slightly larger ship since the eyesight just ain’t what it used to be. At 3/16” scale the model will be approximately 35” long by 9 ½” wide. I also decided that instead of just making a set of 2-dimensional drawings I would try drawing this ship in 3-dimensional cad. I’m doing this for two reasons: One, since this is my first scratch build I will get a much better understanding of how the parts go together and secondly, I have used AutoCAD pretty much since its inception but only it’s 2-D capabilities so I thought to myself, self, maybe it’s time to learn something new. So I will be making a 3-D model of the ship before I attempt to physically build it. This should also save me from wasting a lot of material since it’s a lot easier to erase and redraw than it is to remake a number of pieces. Because I am drawing this ship in cad I thought it would be more appropriate to do so in the ‘CAD and 3D Modelling/Drafting Plans with Software’ forum on this site. So until I start the physical part of this build I will be continuing at the following link: http://modelshipworld.com/index.php/topic/14198-3-d-armenia-by-sald-–-hudson-river-sidewheeler-1847/?p=440043 I apologize for rambling on, like my daughter tells me “TLDR” (Too Long, Didn’t Read), but if anyone would like additional information about this ship please let me know, I’d be more than happy to send it or post it here. TO BE CONTINUED…..
  13. Hello wood-, iron- and steelworms! The very first thing I've to admit is the scale is nominally 1/36 - but due to an enlargment fault it is only 1/40. So I said to myself "Damed 4 dots beside the lne... it could have been the drying of the paper or the wrapage in the big copy machine... so I decided to take the plans as they are - and do the start with them. I've got a thread about the plans here: http://modelshipworld.com/index.php/topic/12596-ss-warkworth-an-early-steamer-not-too-big-please/ andall the planing facts will be placed there. The S/S Warkworth was built in 1874 in Newcastel up on Tyne on the shipyard of C.S.Swan & Co, out of iron. I'didn't find a prpper date of launch only this date on the (usualy coloured) sideview of S/S Warkworth. This can mean she was launched on the 8th II. 1875 or the drawing is dated to this day. Does anybody know something about dating traditions in the shipyards on Tyne? The ship was ordered by H.Andrews who was connected with Broomhill Coal Co. for the coal transport and built in a progressiv design. It is now known that if the angle of the water flowing to the line of the keel after is exceeding about 18°, the flow of water toward the propeller is liable to be turbulent in creasing drag. Due to this the lines were altered compared to former designs. She has got a complete forecastledeck - til the bridge the deck is iron not any longer wooden. To store the new cylindrical Scotch boilers the deck of the boilerroom had to be raisen - the enginerooms hight had to be extended too - due to standing hammer steammachine with a high and low pressure cylider. This kind of construction was basically used for the next three quarters of a century - till the steam coasters started to disappeare in the mid 1950s. The captain was no longer near the rudder as used fore the last 3000 years - hhis place went to a flying bridge infront of the funnel - raised on a little platform called "Flying Bride". To seperate it from the "real" bridge connecting the two side wheel boxex earlier. This interestin light construction gave a good overview to the Officer giving orders to the helmsman behind and below of him at the main steering wheel. S/S Warkworth was built to transport coal - so she had two big cargo spaces of 14,15o and 13,ooo cubicfeet - for ther own coal consumption she had a 102 ts coal bunker. She works in coal trffic on the north-east coast of Great Britain and measured imperial. and registerd with: 160.8 x 27.1 x 12.9 - at 555 grosstons and 334 nettotons. driven by a 70 hp machine on a single propeller. All the data are from Charles V. Waine's books Steam Coaster and Short Sea Traders (2nd Edition 1980) The Collier Fleets (1st Edition 1990) As you can see from the pictures there are not too much details that overcome to us. I couldnt find anything about the propeller - with out the fact that it was a single one... but does he have five, four or three blades? So I'll start with the building board and the backbone next week. The construction of the bulkheads will be shown in the article about scetches, plans and drawings. As all the pre-work is done there and the "output" is shown here to you. The real building progress will be shown here - to give you an Idea of the size I built a little figure for you - standing on a €-cent coin and based on a square-inch he is to scale: MrSquare-Inch EDIT 12/Feb/2016: Due to my flat's groundplan I've to reduce the scale down to 1/4'' to the foot - 1:48...

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
