    Hi Mike Nice work and neatly done.

    Hi Antony good start and nice work!

    making full size yachts! good idea!I have visited a Chinese small dockyard who build small wooden ship,and some small dockyard(or workshop) in Europe can been found out on Internet. They bend plank after heating them with steam,and some metal jigs are used.A large CNC milling machine can process such a large size of plank, a friend of mine who has a furniture factory use this kind of machine.I think these machines can fully meet your idea. I think the cost of processing wooden planks may be about the same as that of making furniture.I don't know the cost of processing in the European and American countries. In China, it is very cheap. The processing of large quantities will even be as low as 1.5 US dollars per hour. The price of the machine is from about 4000 (3 axis) to $100000(5 axis).

    Hi Karl! Nice work and it's a very good reference for me.Do you changed your profile photo? any more introduction to this ship model of 74 gun? Thanks HJX

    Yes,It's flat on the bed of the cnc but the strake is curved,so it needs double sides milling. I have some strange and eccentric ideas - but my behavior is normal, for example, in the Chinese forum, when I propose to use CNC to produce an independent figure-head - without any support or "bridge", many members were opposed or thought it's impossible, but I did it by the same machine without any "bridge". Many people question that the plank was so thin that it is impossible to be machined by CNC. But they ignore that i can use a support, the rough stock of strake can be fixed on the surface of a support, then processed it and installed it to the hull? The frames produced by CNC will be very accurate, and the deviation may be within 0.1 or 0.2mm.-But this is not the traditional method of making ship models, there may be a lot of opposition.

    Thanks Mike Y and Gaetan Bordeleau! I carved one again,and I use more fine textured box-wood this time. But still made a mistake-her left hand was broken, and it was a pity for me. Maybe it will be a year later to continue this project, I have to make the drawings of HMS Victory 1765 first, so maybe it's the last update this year. The purpose of making this project is to verify some strange ideas in my mind. Maybe you will think it's incredible or impossible. For example, I use 3D and CNC technology to planking.Yes,planking! Once i told a friend of mine that I didn't use a saw (manual or power-saw) to make frame of ship model. He asked me, am I crazy?Maybe that's me, and I like to do it in my own way.

    And my fancy is to planking on a substitute of hull (NC machining), and then transfer it to the actual hull, but strake was processed directly by CNC-I have done the experiment in this step.

    Hello Williamo I have seen AlexBaranov made shipmodel by this way（Or close to your idea）.You can search the keywords "cumberland"/"hms cumberland", he introduced the method in his buildlog.

    I'm quite agree with Mark,the planking is really great!-Mark's Bellona is great, too,that is another style like following. HMS Valiant 1790,Science Museum. As to planking,I think it needs good experience and skill.So I think about an inexperienced builder like me how to do it accurately and aesthetically.Although it sounds unconventional,But it's just a way of planking.i make the strake by cnc directly... The benefits are accurate, and any wood can be used.-（But this is my first experiment, version 1, and it doesn't look good enough.）I want to deal with the steps of strakes by this way. But there is a problem in version1.0 that the wood grain does not bend the direction of strake.So,I'm going to use version 2.0.The rough stock was bent first, and then the NC machining is done-this can also save the material. It's a pity that my wife does not agree with me to make ship model.I don't have workroom. She forbids me to make ship model in the office, so I just do some experiments.

    Hi nick He didn't sell products on eBay yet, and he can't speak English. He said he had exported a number of machines through the agent,he can not provide after-sales service to customers.A cast steel engraving machine with a weight of more than 120kg. Secondly, Machines with electric motors are difficult to express or send by mail. (customs formalities are very tedious),perhaps the European voltage is 110V, but 220V in china ...so I suggest you buy it locally. Even if I send you the Chinese website of their company, Chinese is also an obstacle to you. I suggest that you'd better buy a cast steel engraving machine. Secondly, I suggest you buy 4 axis engraving machine. The 4 axis engraving machine can make almost all of the shipmodel parts, even the metal cannon with relief (except for sails).

    Hi Denis Your idea is super cool-wondful. I remember that a member used to use a game engine to make a ship model before, but the effect was not very good at that time. Today, UE4 has an amazing real time effect. It can achieve the effect you imagine.And the software is free (last year). I wanted to do it at first, but I had a crush on CNC, I want to get the true model, so I "over the wall" From the affirmation and expectation of so many members to your work,nice work you have done!
  12. Jack H
    Nice work Greg,and it is a good idea to separate the design of the ship model from the rendering.As you have such a detailed 3D model, the file will be very large in the end, I estimate at least 1G, unless the model is optimized. Simplify the model and restore the details with a normal map(use alfa map),this is a common technique at present. But it takes a lot of time(to do it ), and maybe it's another choice to improve the performance of the computer. In any case, this will be a grand project. CAD and virtual simulation intervention ship model making, as well as more applications of CNC, may be used by more and more people in model making -- just like many power tools used to replace some manual works.

    I use 4 Axis carving machine,3040-Actual processing area 26x36cm. It's my carving machine,the product is being processed and has not been cleaned yet. It doesn't include computer and any software, costs me about $1200 ,equivalent to 8000RMB. This is made by my friend's factory.It is made of cast steel and can engrave the metal and stone such as jade and copper. The precision is +-0.02mm,1500w,water-cooling. He also has a 6090 machine, the table is aluminum alloy. The price of 3 axis's is 7000RMB this year(excluding computers and software),about $1000.

    Hi Gray! After a month's waiting, I received the first book.Building The Wooden Fighting Ship.It's easy to understand and very useful to me( used to develop the 18th Century British 3rd rate ship model from NMM original drawing.) Can you recommend some more books on British 1st or 2nd rate ship in 18th Century? Thanks so much for your helping. HJX

    I want to add that, when you have mastered the 3 axis NC machining, you will look forward to 4 axis engraving machine, but once you have 4 axis engraving machine, it is eager to 5 axis engraving machine (like me), but the mother-board of 3 axis and 4 axis /5 axis is not the same and as far as I know, there is no way to upgrade-You have to replace a lot of parts, and it will cost you a lot of money(to upgrade 3 axis to 4 axis ) , but the 5 axis engraving machine is very expensive, and the CNC program of 5 axis is very difficult, so, I suggest you buy 4 axis engraving machine, because the 4 axis engraving machine basically can make all KITs of the ship model.

    Hi pompey2 I saw your picture of engraving machine. The drawback of this engraving machine is that the less rigidity. When the carving is deep relief or cutting, the vibration of the machine will affect the accuracy. I suggest that you choose the carving machine made by steel casting, the machining precision will be higher and more durable. It's just a little more expensive (if in China). But if you use a laser as Z axis, it would be better to use an aluminum alloy machine. If you need to make 2D or 3D sculpture, I suggest you choose a 4 - axis engraving machine. The 4 - axis engraving machine can make a perfect relief (sculpture) and figurehead. If there is a chance, I will do a demonstration for you(There are great differences between the 3 and the 4 axes engraving machine in making relief-excluding the figurehead).The sculpture made by 3 - axis engraving machine, the side will be stretched. If you are very interested in that machine, ask them to carve a sample for you.

    Great work! beautiful sculptures and ship model, and good reference drawings. thanks
  18. Jack H
    Excellent！ And happy new year to you! HJX

    Thanks imanewbie I made a fatal mistake at the last step and the sleeves were broken.It seems too fat, the head may be too big, uncoordinated. It needs to be optimized again.
  20. Jack H
    Thank you very much Hubac'sHistorian ! After several days of intermittent carvings, the figurehead is about to be completed - the support will be removed.
  21. Jack H
    Thanks Erebus and Terror Nils Mark Gaetan Bordeleau and Hubac'sHistorian! I finished second steps, because my machine is 4 axis, so many parts need to be engraved again. In general, Maybe i can get better sculpture by using new model new processing program and the V type milling cutter. If the eyeball is to be engraved, 0.1mm V type milling cutter is needed, but I use 0.3mm milling cut now. The rssult of the left arm after additional carving.
  22. Jack H
    Hi Mike You can always bring us an amazing ship model (maybe that's ship or ship model ? in 1:1 scale last time?)
  23. Jack H
    After an another project, I will write a new processing program and re - engraving the figure-head with V type milling cutter.I also modified two errors and the face （head),more finer engraving results can be obtained by using the V type milling cutter.

    Thanks shipyard Gary! I have two of them,The construction and fitting of the English man of war, 1650-1850 and The 74 gun ship bellona,The previous one is very professional, However, it is a little regrettable that there are few descriptions on keel splicing. I checked out the introduction of these books, ordered 3 of them. And buy another one. I have some questions about 74gun/64gun/90gun,I'll consult you after reading these books. thanks!
  25. Jack H
    Hello shipyard Gary Great work! I am looking for some books or plans about British 1 -3 rate ship in 18th century,can you tell me the 3 books that are marked in red in the picture? thanks!
