  1. thanks NWSailor That data is not my card number, that may be another serial number, but in order not to cause misunderstanding, I delete it.thank you!
  2. Hi all I completed my first donation today and done it in China through the Internet. I only donated $5 (the transaction fee is $1)-Maybe I'm a miser. This is an experiment.If I use my card less than 4 times a year, I will be charged about $50 in credit card fees, (more than 4 times without paying a $50 annual fee), so I split more than 4 donations.
  3. Although this is voluntary, I use some resources of the website, and the donation of 20-30 dollars is a small sum. I tried to register and learn to use paypal, and I decided that I would complete a donation this year.
  4. 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).
  5. 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.
  6. 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.
  7. 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.
  8. 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).
  9. 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!
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. Hi.

    You posted some inteesting junk drawings.


    Would you mind sharing the link with me.

    Regards Antony.

      If the website is the one prohibit by chunk,i'm sorry that i can't publish or disseminate it in the forum.Another site, which contains many Chinese ship drawings, has been closed.


      If you need some drawings for research purposes, I can consider looking for it for you.


      It may be different from what you think. It's so rare that the ship model drawings drawn by Chinese . Instead, the European ship model company has developed a lot of Juncke drawings.

      Thank you for the reply.

      NP I understand.

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 provide support to our members in their efforts to raise the quality of their model shipcraft.

The Nautical Research Guild puts on ship modeling seminars, yearly conferences, and juried competitions. We publish books on ship modeling techniques as well as our world-renowned quarterly magazine, The Nautical Research Journal, whose pages are full of articles by master ship modelers who show you how they build those exquisite details on their models, and by maritime historians who show you what details to build.
