  1. I would recommend checking out this thread regarding laser-cut frames, etc. Kiyoo Iizawa was actively involved in this forum a few years ago and did some beautiful work using CG modeling and laser-cut components. He was writing a manual/book to help modelers get into laser-cutting modeling, but after some attempts at collaboration, I think there was an (amicable) divergence of views on how to present the process.

  2. IMHO, going directly from existing drawings to code that drives a 2D laser cutter is risky when cutting out frames or bulkheads. I have no experience with the quality of plans from the big national museums and other credible sources, but when I manually compared the body and halfbreadth plans of my 1891 brigantine project, it was an exercise in frustration. Heights and breadths of station and waterline intersections did not agree among the three views. The point I am trying to make is that there is no guarantee that using existing plans (especially if they are old, original drafts) will drive a laser cutter that will result in a smooth, fair, hull surface without a lot of extra work. The above observation was the reason I went to CG drafting in the first place. After nearly a decade of periodic frustration, trying different methods and different copies of plans from the Smithsonian and other museum/library archives, I found that using the DELFTship Free naval architecture software was pretty much ideal for fairing out the hull lines because it had the features needed to visualize the shape of the hull, remove low and high spots, and compare the resulting lines to the original drawings. The bottom line here is that obtaining a set of working plans that will actually be fair and eyepleasing in the real world won't necessarily yield the same set of station lines, waterlines, and buttock lines as in the original set of plans you obtained. It is up to you how far you are willing to deviate from the original drawings. There are a number of MSW members who have posted their projects using DELFTship Free, including my own. Comparison of the final modeled stations (green) in DELFTship Free compared to the original G.C. Berger drawing stations. Waterlines (blue) were included to ensure the correct vertical scale. To understand the genesis of these lines, please refer to the Galilee research log in my signature. (High-resolution plans obtained from the San Francisco Maritime National Historical Park Library; G.C. Berger, Pacific Marine Research Society; Date and provenance unknown.) Once you have what appears to be a valid set of lines to work with, then you can start thinking about what laser setup to use for cutting out your parts. Remember to cut to the outside-most of the front and back curves for each frame or bulkhead. Terry
  3. Welcome aboard, Kevin! Yeah, the Lewis and Clark is nothing but HY-80 razor blades. There are quite a few (mostly former) bubbleheads as members here. Terry
  4. Hey, Deyson. Another Coloradoan! Where are you located? I'm retired and living near grandchildren in the Springs. Great to have you aboard! Terry
  5. Viriato. Eu sugiro usar o translate.yandex.com tradutor português / inglês. Isso parece fazer um trabalho muito preciso. (I suggest using the translate.yandex.com Portuguese/English translator. That seems to do a really accurate job.) Terry
  6. Try reading it via the link on a mobile phone. Worked fine for me. Sad outcome.
  7. You guys should work up a tutorial for developing laser patterns for things like cabin and roof planking, skylights, and other fine details. You might even start a small business of doing bespoke laser cutting jobs to pay for your hobby! Terry
  8. Is there a simple way to add realistic crew in these renders? The main thing that indicates your image is artificial is the absence of any hands visible on deck, or at least at the wheel. Galilee had only eight assigned crewmembers (plus the five scientific expedition members), and all the photos of the ship at sea always had at least a few humans visible topside. Terry
  9. Most browsers have a feature to translate text to the user's default language. Looks pretty clear to me. Nice job on Bismark! Terry
  10. Not sure who to send this to, but I received this security message when I tried to access the site's article database: Probably not related to this weekend's mishap, but thought you should know. Terry
  11. Where do you call home? I lived in Vermont several times in my life and consider the state my favorite. Lived in the greater Burlington area. I also drove LCT ferries to work my way through college (UVM). Best job ever! Terry
  12. Looks like you are using Sketchup. Nicely done! Terry
