  1. Mark, Yes, that is a big reason I love these ships, especially this time period. Everything is curved in different directions, and yet so gracefully resolved. Ron
  2. These are quickly grabbed online of Victory, how applicable I don't know, but they look to me like sill and heads are following the deck.
  3. Speaking as an architect, not a shipwright, my preference would be for the sills and heads of the lights to be parallel to the deck sheer. You wouldn't have that triangular sliver at the heads that way, and it would look more natural from the inside.
  4. Thanks for all your advice, druxey. Phil, your centrifugal casting technique looks good, thanks for the tip. Probably won't try it this time around, but if I see an old centrifuge for cheap, I might go for it. wefalck--yes, mastering a new technology is probably the primary reason for me wanting to cast the anchors. There will be four, each a different size, and I am making the masters out of wood. I could more easily just paint the wood masters, and not cast anything. That is my back-up plan if I'm not able to get a good result casting. I had bought a piece of brass the thickness of the biggest anchor, but thinking about cutting 4 anchors out of brass, and filing them all down by hand seemed even more work than the casting. Making the forms out of wood vs. brass is definitely easier for me. Printing these, and the many other parts that could use that technology kind of defeats the purpose of the hobby for me. I guess casting is kind of analogous to printing, but it still seems more of a by-hand process, which appeals to me. Ron
  5. Steve, The molds will be rtv silicone rubber. I was able to find your build log--a sweet model! I definitely can't manage the centrifugal casting arrangement you showed. I'll see how it goes. If I am not able to cast them well, I'll do the anchors another way. Ron
  6. Druxey, I will make the filling vent/funnel larger, it's good I can recycle the metal! I think I need to get a larger crucible. I am doubting that the spoon/ladle that came with the casting "kit", will hold enough metal. Steve, I have wondered about this. They will be long, narrow pieces to cast. I was puzzling over whether a lower melting point was better or not, as it's not as big a delta from the mold (maybe won't cool down as fast as a higher temp metal?). I have also read that heating the mold before pouring can help, and I will talcum powder the mold also. I don't think centrifugal force is an option, unless there is a safe way to do this by hand. Is a higher melting point alloy better for this type of casting? Ron
  7. Question for those with experience casting: I am going to try casting my anchors for Oneida. It will be the first time I have tried casting. I'm using the Micro-mark 280 metal (280 degree melting point). How should I orient my anchor patterns in the mold? As on the left, or as on the right? Ron
  8. Here are the copies of the anchors. The two round-arm, iron-stock anchors need two patterns--one with the stock, and one with the arms-- I've decided to do the 1500#, 1200#, 800#, and 400# anchors. Here are the patterns glued to some pear stock. Wasting more wood than I would like, but I couldn't really figure out a more efficient way to lay them out without going diagonal. I thought I should keep the grain parallel to the shank, though that does make the arms susceptible to breaking-- The holes have been drilled and I'm filing away at the brass strip of preventer plates-- Varying stages of progress-- Four preventer plates parted off--they look a bit chunky, so more work is needed on them to slim them down a little. And the anchors in various stages of being cut out, sanded and filed-- Ron
  9. Michael, Photos can be inaccurate, but that color seems to be developing very well, and I applaud your patience in having to be careful with so many coats! Ron
  10. Romulus, Welcome, and it is interesting that you are a professional ballet dancer, and are interested in this hobby. I have three daughters who studied ballet for many years; one of whom still dances professionally. I don't think any of them would start a ship model! As druxey says, any help you may need is available here, and I hope you will continue after the "shut down" is over. Ron
  11. Thank you, Andreas. I have a few things going at once, having finished the bow work. I'm still sanding the Channel pieces into form, and also cutting out 20 Chainplate Preventer Plates from a strip of brass. I did one, to test, and will now mark and drill the holes for all twenty, and try to do them more or less all at once-- I am also beginning preparations for making the anchors. Oneida was to carry five: 1500lbs, 1300lbs, 1200lbs, 800 lbs, and 400 lbs. I think I will be making 4, though not sure which ones yet. As this was a transitional period for wooden stock vs. iron stock, and angled arm vs. round arm, I am thinking of two of the larger ones as traditional angle arm, wooden stock anchors, and the two small ones as round arm, iron stock. It seems there is some evidence that the smaller anchors were more likely to introduce the iron stocks. I'm going to try and cast them, which is something I have never done before, so we'll see how that goes. Since I'll have the wooden forms for the casting, if the casting doesn't pan out I can paint the forms and use those. Here is a page from Petrejus's book Modelling the Brig of War "Irene" showing both traditional and iron stock anchors, and Charles G. Davis' book The Built-Up Ship Model showing a round arm anchor (though with a wood stock), and my notebook with calculations for the sizes. I used the formula Charles G. Davis gives in his book. I calculated just the shank size, and will Xerox copy the illustrations to multiple sizes so that the shanks match my calculations. That will give me scaled paper patterns to cut out the wood forms with-- I also adjusted Davis' formula to check it against a table of anchor sizes in Lavery's The Arming and Fitting of English Ships of War, and got results that corresponded reasonably well to that table, so I am somewhat confident that my anchors will be close to the right size. Ron
  12. Post #80, Photo 1 (though other photos show it also, this one struck me)-- There is indeed a human being in this cold, sterile place, building this beautiful thing. Ron
  13. Steve, Yes, you won't need the detail from the Chapelle plans for a while. Hopefully by then we'll all be back to normal! My frames are actually Cherry, as are the deck beams and knees. The keel, stem, sternpost, and hull planking are Pear. The decks are Maple, and there is Castello Boxwood here and there. I think your Maple frames will be nice! What other woods did you get? I love that all the Oneida's are different. Ron
  14. Beautiful work, CRI-CRI. From your scale figure, La Niña, is actually larger than I thought her to be! I'm looking forward to watching your model develop. Stay safe, Ron
  15. OC, The monstrous alligator clip in the previous post was a shocking reminder of the scale of this. Nice work. Ron
  16. Thanks, Steve. I try to set a high bar for myself, but I am far from a perfectionist. I am pleased that the model comes across well. The willingness to do things over (at least some of the time and to a point) is something you have to have in this hobby. To think that you'll get everything right the first time is unrealistic. Great that you received your Oneida, and I hope you are planning to start a build log. I would love to watch (and help when I can) another version of this ship take shape. There are a few out there and they are all different. The 1/4" Chapelle plans are beneficial. How much so depends on how far you want to take the model beyond Dave's kit. Rigging for example--if you're not rigging it you obviously don't need the sail plan. If you are going for the fine points, I think the hull plan helps a lot. Dave was very faithful to Chapelle's plan, but there are small differences, and some details left out. I think this was to make a slightly simpler model, that worked with what the kit supplied, as is the case with most kits. The 1/4" drawings are just nice to have also, though being simple B&W copies, they aren't as visually rich as the British museum plans of those ships! Good luck! Ron
  17. Thanks, Roger. I feel more connected to this model than I might another, because the ship was built and sailed in my "neck of the woods". Work now commences on the channels. I marked the rough sizes on some wood stock-- I cut the overall piece out, and sanded it to approximate maximum thickness of about 5". It will eventually need to be 4.5" on the sides that meet the hull, but I like to give myself some leeway initially. I re-marked the center line, which will be the hull side when the individual channel pieces are cut out, and scribbled on each side of the centerline. These areas need to taper down to about 2 1/2" at the edges. I sand them on a piece of sandpaper laid flat on the table, using finger pressure to create the bevel. The centerline marking and scribble help make sure I am not sanding the center-- Here is progress on one side, a little more to go-- I think in hindsight it would have been better to make a single long strip, so to only have to sand one bevel. Next time. In order to correctly angle the chainplates, I need the masts in place to run a "dummy" shroud down to the channels and use it to successively mark the angle of each chainplate and notch in the channel. Here are the masts temporarily fitted-- I haven't measured the exact rake angle, this is just by eye, looking at the sail plan. I will be sure to do that before marking the chainplates-- Ron
  18. Bob, Great job. It's very interesting to see someone with your skill level bringing a sensibility--the weathering and real world coloring--that one tends to see in plastic, but not as much in wooden (ship) modeling. Those photos taken outside from earlier in your log are especially effective. Ron
