    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

    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.

    Thank you very much Hubac'sHistorian ! After several days of intermittent carvings, the figurehead is about to be completed - the support will be removed.

    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.

    Hi Mike You can always bring us an amazing ship model (maybe that's ship or ship model ? in 1:1 scale last time?)
  12. 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!

    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!

    Nice work Igor, and the rendering is wonderful.

    It's really beautiful, today I watched two times. The sculptures are gorgeous and amazing. HJX

    Vector Magic,But it's not smart enough

    Hi I don't know what software you used, as far as I know, if you want to make 3D models and mill it by NC machining, you also need 3D modeling software.I recommend X+zbrush,the X is cad software such as autocad/rhino/solidworks/UG/...,ZBrush is used to make sculptures,it works very well and is much cheaper than 3DMAX /maya... and other software. These software are generally expensive, if you don't work in some companies that use CNC (they can buy these machines and software), maybe you don't have the chance to learn these professional software. I benefited from my friend who have a furniture factory, he had a lot of CNC machines and software that made me learn how to use these software.

    The 4 axis engraving machine can make almost all the parts of a ship model-- except sail, the 3 axis engraving machine can produce most of the parts of the ship model. Some parts which are difficult to be produced by traditional manual methods, but they are machined quickly and accurately with the engraving machine. For example, some special shaped parts of the bow and stern.

    Hi pompey2 I've used a desktop engraving machine, -4 axis.The machine is all made of cast steel. The price is about $1200, excluding pc and software.The Mach3 license will cost about $175.You also need a computer, but you can use the old one, Mach3 does not require high performance for PC. You also need programming software and design software,it's the costs that need to be considered.Most importantly, you must design and learn to program.In China, tuition for embossed programming is more than $1000. Only for the engraving machine itself,If you are only occasionally used to process some wood parts, such as cutting frames, and making some relief, the Aluminum Alloy Structure Carving machine is more cheaper. but as far as I know,the engraving machine, the price under 500 dollars, is called a "toy machine". The benefits of engraving machines are unquestionable, accurate, labor-saving and high efficiency. Able to process relief and make complex parts.

    Hi ALBERT It‘s really wonderful,very exquisite and beautiful!
  22. Jack H
    really pretty good!The schedule is quite fast

    Hi Marcus! I 'm looking forward to your ship model of Statenjacht 'Utrecht' . I've never found the flute zeehaen's inside structure drawings on bow and stern.Later, I personally felt that the structure of zeehaen might be closer to a ship like Utrecht.Because there is no basis, so have been shelved, did not continue to make, maybe I'll change my mind and change it into a hull model.
  24. Jack H
    Great. Are you going to make the two parts separately and then merge it into one shipmodel?
