  1. Old model, new photos. I finally got around to taking better photographs. First I had to complete some unfinished details and cleanup.
  2. Barco de água Acima roughly translates to "boat of the upper river". It was designed to transport cargo from the shallow upper reaches of the Tagus River and via canals. The boat's tender is called a chata, which directly translated means 'flat', but in this context it means a flat-bottomed boat. It is my second wooden model, second model of any kind since I was a young teen, and the first built from scratch. Not counting glue and paint, the only commercial parts are the rigging line, the cloth, the chain, and about 13 small wire rings. I fabricated the remaining metal parts
  3. An updated link to Bob Comet's models. I did my last model this way as well (painted one side, not the other). Zero paint was not an option, since the original was so colorful. You can also see pictures on our club's website. Notes: The MSW link above does not yet have any photos of the unpainted side. I'll add some later. But it shows that the model can be viewed as fully-painted from many angles. For this reason, I would paint a flat transom and any tumblehome on the (mostly) unpainted side. The link to our website is not yet active. I hope to finish it soon.
  4. I stopped posting in-progress photos because I was frantically working to finish for our club's exhibit at the Mariners' Museum.I've posted some poor-quality pictures taken in a rush, with inadequate light and cameras that were not up to the job. They're a little grainy if you zoom in, and the depth of field is poor. I hope you enjoy them anyway. I cannot take any more until next year when I get it back.
  5. A friend on a Portuguese forum suggested that this is to control the tip of the yard when lowering it. I was originally thinking the block was attached to the yard. But if what he suggests is correct, it must be on the mast, and this makes more sense. As the yard is dropped, the line is no longer running parallel to the yard, and it has more leverage. There is only a line to one side, which implies the center of gravity is farther up the yard than where the halyard is attached. Consequently, as the yard is lowered and the tackle at the foot of the yard is slackened,
  6. I have some questions about the rigging, if there is anyone willing and able to answer. 1) I cannot figure out the purpose of the line marked with the red and green arrows. http://www.hrsms.org/home/dl1288?display It is not labeled as, and does not appear to be, one of the brails (Carregadeiras da vela, #8). My only guess is that it is intended to bow the yard by pulling on the tip of it, in order to change the shape of the sail (put some "belly" into it). But once drawn tight, it will run right along the bottom of the yard, and a great deal of tension would be required to bend
  7. Not much has changed in 7 months. I spent most of that time repairing and then sailing a small sailing dinghy (a Force 5). Hopefully I will get more modeling done over the winter. More @ http://www.hrsms.org/home/Cule+and+Chata
  8. Culé Hull Construction As with the chata, I was not confident in my templates, and resolved to do final shaping on the building board, remove the side fames, cut away the inside shape, and then attach the floors. There is too much rocker to easily build it right-side up, and too much sheer to build it upsidedown on a flat board. So I created a wedding-cake (layered) board to add stability and minimize wasted material. Given the larger scale, I did not need solid spacers and full-width blanks, as with the chata. So I created an interior framework, wider toward midship. The pieces
  9. Construction of the chataThe ribs were created from 0.05" (1.25mm) blanks of cherry. I was not confident in the accuracy of the drawings nor the templates I created from them, so I planned to do final shaping after assembly on a building jig. This required the ability to remove the blanks after shaping so that the inside could be cut away. Since there is no keel, temporary spacers held the frames in position and provided support while shaping the delicate pieces. The spacers could be removed, and pegs allowed each blank to be removed from its spacer, the inside cut to shape, and then ret
  10. Culé ou Barco de água Acima I got the plans for this boat at the Museu de Marinha in Lisbon when our cruise ship made an all-too-brief stop there. The museum is incredible. Barco de água Acima roughly translates to "boat of the upper river". It is designed to transport cargo from the shallow upper reaches of the Tagus River and via canals. The cruise was in 2005. I started work on the boat's tender in 2006. As you have already surmised, there have been long periods of inactivity... The boat's tender is called a chata, which directly translated means 'f
  11. Thanks to you both. If you can cite any references, I would appreciate that info too.
  12. To be clear, we are talking about both treenails and spikes in the same joint, not in different locations of the ship (all treenails here, all spikes there). Why use both in one joint? Perhaps the spikes give some immediate grip before the treenails have had a chance to swell?
  13. The drawings from which I am building my model do not include fastener details. So I am using a book on another type of vessel that, though not very similar in appearance, does share some key characteristics. I have a question about how to interpret a drawing from that book. The question is whether a detail for connecting frame timbers using treenails is 1) only treenails or 2) a combination of treenails and spikes The drawing and more details on the question can be found on a page for our club site. Opinions will be gratefully received. Thank you, Greg I've found th
