  1. Very cool looking ropewalk Graham! I ve found that the most critical bits in a ropewalk are the shape of the spindle and the bearing thingy that allows the rope to spin freely as it is being made. It is extremely satisfying making rope and almost all settings will actually work. Another key element is the yarn, I have used quite a few but still have not found the ideal one to make a rope that will not stretch and that will be supple as a rope should be. Looking at your two ropes in the photo, maybe it needs more twist, more weight pull and more acute angle at the spindle, the base of it maybe needs to be more wide Regards Vaddoc
  2. In the boat I currently build, I spilled all 35 planks, some very heavily. The 2 mm maple refused to bend sideways but very happily bent any other way. Some planks were 80 cm long and after the first 2-3 planks I standardised a method. Best to spill, very satisfying too. You will not convince a 2 mm strip to take this bend!
  3. Yes, don't be too concerned with spilling. After a while it becomes routine
  4. My experience has been a bit different Jeff. I ve never used or even seen holly. I ve used swiss pear a lot though. I ve found that it does not like bending much. It can but it needs a lot of force to keep it in shape, it can fracture suddenly and does not respond well to steam/hot water bending. Also, it resists sanding as it is hard. At 1 mm any wood will bend. At 2 mm, you might struggle with pear. Maybe I am wrong though. Of all the timbers I have, pear strips are the only ones that even after many years they are still dead straight, everything else has warped with moisture changes and time. My 2 cents
  5. What have you received today?

    I received a virus from my daughter. I am running 39 C (that's hot in F) and I simply can't fall ill at the present time! Best not to check my temp again methings...
  6. Cataracts---Choices for Vision Correction

    Most of my family's elder members had cataract surgery. Only my dad had a bit of bleeding (he is on anticoagulation) which cleared it self in a few weeks. There are a few more on the waiting list. None was asked about far or near vision, they are all happy nevertheless. Of course it needs to be treated with respect but does not seem a mountain of an operation. A friend eye surgeon told me how cataracts are corrected in the wild parts of Africa. They pound a special herb into a pulp, then apply it to the eye. This anesthetises the eye. Then with a very sharp needle they knock the lence off and throw it back into the eye. The patient looses ability to focus but gets a very clear peripheral vision, which is an improvement from not seeing at all. Don't know if it is true. I think you should consider two ancient rules. Don't fix it if it is not broken and better is the enemy of good.
  7. I actually read a paper or some kind of study some time ago. It showed that in response to changes in moisture, there were minimal dimensional changes in wood along the grain but very significant across, sometimes with changes in width up to 20%. Different species behave differently, wood database report this as "movement in service". Where I live there are dramatic differences in ambient moisture between summer and winter. In my previous home, all the nails in the walls were coming loose and the doors would not close during some months! Interestingly modified woods like akoya will not shift. As we use pieces that have a huge surface to volume ratio, I would expect they easily adjust to ambient moisture. Really PVA glue should not take any measurable space.
  8. Some questions about shrouds

    Well, this has been a very satisfying thread, I got answers to questions I never new I had! Good luck with your boat Vinnie.
  9. It looks like they messed up a bit with the masking tape for the waterline! Many thanks for letting us know of this awesome project.
  10. Power versus Hand Tools?

    If you work in your living room or somewhere in the house, power tools probably should be avoided due to noise and huge amount of dust. My first ever model was a simple scratch built one, did it in the living room with absolutely no power tools. Then I moved and had a garage. Power tools made building more enjoyable and accurate but as Mark said it will always be a combination of both and imaginative thinking is always needed to effectively use tools. Most frequent tools are a home made disk sander, dremel moto saw and dremel rotary tool. I recently got a proxxon mini table saw which I seem to be using all the time. I would love to get more tools though!
  11. I used 2 mm maple in my current build. 30 secs under hot tap water and I could get the wood to take extreme twists but mahogany does not like bending much. My experience is also that it can have interlocked grain, same as walnut which often suddenly breaks instead of bending.
  12. I ve used many thousands of treenails in my current boat, mainly to hold the planking in place (no glue used). I also use 1 mm screws to temporarily hold things together and then remove them and fill the holes with tree nails. For a quick way of making them in bulk, at any size have a look at this https://modelshipworld.com/index.php?/topic/13063-tree-nails-in-bulk/&tab=comments#comment-398038
  13. This is beyond my skills and I live in UK but I wish I could help. Hopefully someone else will be able to.
  14. I think it has to do with the amount of spilling needed and the timber you would have available. In the boat I currently build, the planks needed very significant spilling. So, if I wanted really wide planks, to accommodate the curve the trees would need to be huge. For ships where straight planks were used, these could be wider. Also, it depends on the curve of the hull at the bilge. Very wide planks will not accommodate the turn of the bilge well or would need to be very thick so they could be shaped concave. Much easier with narrow planks. Other possible problems, the more wide the plank, the more difficult not to have defects and the more difficult to steam, handle and bend into place. For models, I think a compromise of the above. Planking is easier with narrow planks but takes much longer. I started with 15 planks each side but were too wide, then wanted 22 but would take forever, finally settled for 17 which proved a sweet spot. My 2 cents...
  15. Who bit the apple

    Dear all, I feel I need to share this with you. I had my 3 year old daughter in my lap and my macbook was next to us. She pointed at the Apple logo and said "look daddy". I asked her "what is this" and she replied "an apple, but is damaged". So I asked "who bit the apple" and she replied: "Snow white"! Vaddoc

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.
