After a twenty year break from ship modelling COVID got me looking for something to do. Just before I had stopped building I had started 2 LCT(4) hulls in styrene sheet. One of these was only a hull but the other was well advanced and had actually sailed as an RC model. I did some detail work on this, modernised the radio and sailed it. First picture. The second hull has also progressed but is not yet complete, could be the subject of another build log. For Christmas 2020 I got a 3D printer and after a while started to wonder whether I could make a printed hull. An LCT hull seemed to be a good place to start as they are relatively simple. I already had a LCT(4) and an LCT(5) so I thought an LCT(2) or (3) was a good option. These two variants used the same basic hull but the 3 was longer by 32ft. This choice was confirmed when a friend sent me a builders plan for an LCT(3). Drawing started in August 2021with a midships section, the easiest, as everything is nearly square. Second picture is the aft midship section on the printer, the third, the stern, aft midship and midship sections

As I mentioned in the "What did you receive today?" I mentioned about a ship I wanted to have in my yard. This ship is a Swedish first class coastal defence ship, with keel laid in 1899 and launched 14 August 1901, one year later she was commissioned. The name is HSwMS Äran ( Swedish for "Honor") Here is the stats of her: Length: 87.5 m (287 ft 1 in) Beam: 15 m (49 ft 3 in) Draught: 5.3 m (17 ft 5 in) Propulsion: Steam triple-expansion, 2 screws, 7,400 shp (5,500 kW) Speed: 17 knots (31 km/h) Crew: 301 Armament: 2 × 210 mm (8.2 in) m/98 6 × 152 mm (6 in) m/98 10 × 57 mm m/89B (plus two 37 mm guns on smaller craft) 4 × 90 cm searchlights m/00 2 × 450 mm torpedo tubes Armor: Side belt 175 mm (7 in) Turrets 125–190 mm (5–7 in) Deck 25 mm (0.98 in) Conning tower 200 mm (8 in) She saw two world wars but did not participate. Decommissioned 16 June 1947 and sold for scrap in 1961. Äran was one of four ships built, the other names was Wasa, Tapperheten (Bravery) and Manligheten ( Masculinity). There are not that many pictures available. I have contacted the Swedish Marine Museum and they have very little information as well. Here is a color picture of Äran steaming through the Swedish archipelago. Now some picture of the build. She has a total length of 4ft. (1:192 scale) She will also be remote controlled - most of the parts are 3d printed. I have some projects ahead of me, learning how to create my own PE parts and other details, not printed. More picture of the parts will follow.

Starting this topic to explore the FreeCAD program and discuss techniques to be used. Being relatively new to the 3D CAD scene, the approaches will be relatively simple and sometimes wrong and can be improved. The project used as an example is a hull model of the New England fishing schooner Adventure and supporting information from http://schooner-adventure.org/about-us/ and details from Howard Chapelle's "The American Fishing Schooner". At some point photographs of the real schooner will resolve details. The objectives of the project are to understand some techniques for getting the 3D hull built, to get as realistic rendering as possible, and explore the opportunities for 3D printing with various options. I have been inspired by some amazing work in other topics in this forum "CAD and 3D Modelling/Drafting Plans with Software". Attached is a current rendering with many unresolved issues. I plan to go back and show how this was assembled and then move forward on the issues. Hoping that this will be of interest and that others will contribute.

Not sure this has been mentioned here yet. I bought one for $560 AUD, so US would be around $500 or less I reckon (though it IS from China, so not sure how the price will go there for you guys now!...) Initial tests of its capability have been very impressive, the detail is astounding - the attached columns are 40mm high. Downside is that resin is a messy mediun and prints require post processing - washing in Isoproyl alcohol and then curing under UV (ie sitting out on the back deck in the sun for a bit), its also a bit fume-y so using it in the lounge room in front of the telly is not on - its a 'down the back shed' style tool. Also build size is limited, but I certainly see a use for it and will be happily mucking around with it for a while yet.

As it was the retired period from a 40 years period of tv, graphics, and 3d projects, i said it is time to test a second tool. The first was a laser and CNC tool. Now i bought a 3d printer to make from scratch, and i will show some tests. This are some of the first tests, working for the ship hobby. I also mede some "toys" for my granddaughter, just to see how to work. It seams it is a good tool, and to test parts for ships is excellent. I will show how i build, pictures and explanations soon Cristi

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.
