      An Incentive to Start A Build Log - New Plan Set from the NRG   03/17/2018

      An Incentive for Starting a Build Log

      The NRG’s Generic East Coast Oyster Sharpie plan sets have been selling out – we had to reorder prints 2X already.

      BUT nobody has started a build log yet.  As an incentive we have decided to reward the first three (3) MSW / NRG members who purchase the plans and start and continue* actual build logs** from the plans. 

      The build logs should be started in the scratch built forum and labeled with Generic Sharpie – by “your ID”.  When we have six or more build logs up and running we will set up a group build area for the Generic Sharpie build logs.

      The winners will be able to pick any one of the prizes listed below:

      Free registration for one day at 2018 or 2019 NRG Conference                  ($145 value)

      Shop Notes 1 and 2 set                                                                         ($60 value)

      Nautical Research Journal – all content set

      4 – CDs or 1 Flash Drive            ($150 value)

      Continental Galley Washington Plan set                                                    ($65 value)

      1 year NRG membership or extension                                                      ($50 - $62 value)

      THE RULES

       

      *“Continue” means that multiple posts containing build log content must be made for a minimum of 30 days after the initial post.  Logs will be tracked by starting date and the first 3 that have continued for 30 days following their initial post will be declared the winners.

      **Note the words “actual build logs” – no fair showing a few pieces of wood and going no further just to win. 

       

      The NRG has a new set of plans available for purchase with a free 200+ page full-color monograph .  Check the NAUTICAL RESEARCH GUILD NEWS forum below for details.  This plan set is developed for the first time scratch builder with limited tools and experience.  All materials are standard strip stock available from hobby wood suppliers.  However, it is also a great project for the more experienced builder looking for a smaller project to take a break from the bigger builds.  Remember MSW Members who provide us their real name are considered members for the discounted price.  An email or call to the office before you order with your real name and MSW user name before you order is needed for the discount code.

  1. Aaannd .... here is the final image in this topic showing the capstan and windlass in the context of the forecastle space. Based on my reconstruction of the Galilee plans, there will be about 39 inches of room between decks, so I had to downscale the windlass machinery to fit. I also flipped the clutch actuator so that I could maximize the size of the rest of the equipment. The image seems tilted because the equipment rests on the extreme forward sweep of the deck sheer. There is a 4-degree slope at this point on the deck. Anchor chain comes up from the chain locker through pipes in the deck immediately below the wildcats and lead forward through chain stoppers (not shown) to the hawse pipes in the bow.
  2. Here is my reconstruction of the Galilee's capstan, based on the DTM photo of the upper 2/3 of the actual capstan, with reference to a 1915 Hyde Windlass Company catalog and a random photo of another similar capstan I found on a photo sharing site. While Sketchup can support creating such models, there is a lot of fiddly mesh editing that is required, involving many hundreds (thousands?) of faces and edges. To minimize this cleanup, I created a clean version of a one-sixth sector of the capstan, then did a rotational copy five times to duplicate the sector, resulting in a complete model. The next step will be to marry the capstan to the windlass, then place them in context with the decks and structural members as they would have been on the ship itself. This will help me work out the details for framing in the vicinity of this machinery. Terry
  3. I finally finished drafting up my reconstruction of a Hyde windlass that could have been installed in Galilee. It uses components from Hyde hand windlasses found in ships contemporary with Galilee that served on the West Coast of the USA. Since the prototypes were found on ships larger than Galilee, I will likely have to scale this down to a size that will fit in her forecastle. I am hoping to develop a model of her capstan, then show the combined capstan/windlass machinery as it might have been installed in the ship, with appropriate timbers and decking. Oh yeah, and that band brake operator contains a true 2-inch trapezoidal ACME thread developed from ANSI references. Quite fun to make! So far, most of the major components have been separately built in Sketchup Make 2017, and are manifold, which means they could be 3D printed if desired. Terry
  4. You are correct, Druxey . Never heard of the play Paul Pry I wonder if that is where the phrase "prying into someone else's business" came from?
  5. Update on my reconstruction of Galilee's capstan. I am three weeks out from a repair of a 25-year-old hernia repair, so I've been recuperating rather than sitting at a computer... (for you older guys, my surgeon informed me that redos of inguinal hernia repairs in men are quite common. The joys of aging!) These images show progress and corrections from the previous post. I have most of the key components modeled in Sketchup Make 2017. The only things left for the windlass are the controls (ratchet pawl, wildcat band brakes, and capstan clutch lever). I realized after the fact that the double pawl wheel shown previously was applicable to the lever-style capstan I was using as a reference. It has been replaced with just the windlass pawl ratchet wheel. Please feel free to ask any questions. Terry
  6. Note that Sketchup's default image import resolution is pretty low. To maximize the line sharpness of imported images, which is essential for tracing plan lines, do the following (applicable to Windows systems): 1. Navigate to Sketchup Preferences. (Window|Preferences) 2. Select OpenGL 3. Check Use maximum texture size. 4. Click OK. I included a screenshot of a windlass plan in the default and max resolutions so you can see the difference. These are rendered using a high-end graphics processor, so you can see that it is Sketchup that is affecting the appearance. Large images at maximum texture sizes will slow down the editing process without a good graphics card. See the Warning screenshot.
  7. Here is the current status on reconstructing Galilee's windlass using the resources I have available. The diagram is constructed in Sketchup Make 2017 using the basic tool set. This part is probably the hardest to create, with all the curved surfaces in the wildcats and the crown gear. All that remains is creating the operating gear and the mounts to the ship's frames. I suspect that the windlass was mounted to the deck structural timbers, similar to the Lucerne and Thayer, rather than having a separate metal foundation like the Balclutha. I'm hoping that this will be 3D-printable, but the level of detail at the anticipated scale of the model will probably be lost or not printable. Terry
  8. Thanks Roger—good call. Sadly, the Thayer's windlass is actuated by a rocker-type mechanism. It has a standard capstan forward on the forecastle, but there isn't any indication it is linked to the windlass. However, it is a Hyde windlass, so I should probably be able to pattern the wildcats and related hardware based on these drawings. It seems this type of windlass was bolted to a pair of bitts. However, Galilee had only one large bollard located centerline and forward of the capstan. Evidently, the windlass supports were incorporated into the forecastle framing.
  9. Took a few hours today to do a detailed search of the Web on this topic. The only things I came up with were the following. Balclutha, which is one of the premier museum vessels held by the San Francisco Maritime National Historical Park, is extremely well documented through the National Park Service HAER program. Several of the scale drawings in that program include diagrams of the anchor windlass, which is shown below. Though the Balclutha is much larger than Galilee, she is almost contemporary to the brigantine. The following diagram shows Balclutha's hand-powered anchor windlass. The photo below that I found on Pinterest of capstan/windlass of the sunken Lucerne (check out the Wikipedia article) is probably more similar to the one Galilee carried. Since there doesn't seem to be any contemporary diagrams available of a Hyde windlass, I'll have to approximate one when developing the ship's plans.
  10. Bill, thank you for the link to that HWC catalog. It is my impression that, by 1917, Hyde had dropped their manual/hand-operated windlasses for all sorts of powered types, which are described in the catalog. During the transition period (probably around the time this ship was built), steam windlasses still had a capstan for motive power when steam wasn't available for some reason. That is why the capstan is geared into the windlass from a point above the unit, as shown in the brass model I posted above. Still, the book is an excellent reference, which I will definitely save. Roger, any windlass originally designed for operation by steam won't work for my purposes. Galilee was one of the last of the sail-only brigantines built on the West Coast for merchant service. She originally had a small steam donkey engine amidships for handling cargo and boats, but that was removed during the time my grandfather sailed in her. The crew operated the capstan/windlass by the traditional means—capstan bars and hard work! I'm pretty sure the windlass was operated from the capstan above. As the photo below shows, there was no room for the crew to operate the machinery for raising and lowering the anchors between decks.

Thanks again for your responses and interest. Terry
  11. Hello, All. I've been searching for any plans/photos/schematics of a Hyde Windlass Company (HWC) hand capstan and windlass assembly. This would be sized for a 350-ton sailing merchant around 1890. The brigantine Galilee was launched in 1891 in California and seems to have been equipped with a Hyde capstan (see the photo below). Photo courtesy of the Department of Terrestrial Magnetism, Carnegie Institution, Washington DC (c. 1907) (The attire of the men is somewhat strange. The research crew's surgeon is on the right and his steward/surgical assistant is dressed for surgery.) What I really need is some information about the windlass, which was located in the open forecastle under the deck. I would like to render this equipment as accurately as possible, since it will be visible in the finished model. An entire windlass/capstan assembly has been modeled; its images are available on the Web. However, all that i have been able to find are steam windlasses, like the one shown here. Galilee's windlass was strictly manual. I have already contacted the Maine Maritime Museum in Bath, ME. They have some extensive archives pertaining to the HWC (which became the Bath Iron Works Shipyard), but their staff is limited and they haven't been able to find what I need so far. If any members live in or near Bath and would like to look into this, I would be very grateful. Terry
  12. Floyd (fnkershner), I would be happy to provide some Sketchup coaching for your project at no charge. I am a retired professional educator and enjoy helping people learn new things. What you want to do utilizes just basic functions of Sketchup. Solid objects created in Sketchup are inherently manifold and 3D-printable unless you break the envelope or introduce extra geometry in an uncontrolled fashion. Please PM me with your email address if you are interested. Terry Colorado Springs, CO
  13. Here is a quick-and-dirty build of Galilee's hull I did in Sketchup a number of years ago using an old set of plans I developed back in 2002. Just wanted to see how it would work to display hull form. Unlike parametric 3D programs and for-the-purpose naval architectural software (e.g., DELFTShip), the result shows distinct polygons when you display hidden lines. It is also a lot of work creating the intersections at stations and waterlines. Terry
  14. Here is the instructional PDF for creating sockets in 3D objects. Please let me know if there is anything that is unclear, and I will try to explain it. A real power-user of Sketchup may be able to come up with a quicker method. I've been using Sketchup almost as long as it has been around, and I'm afraid I've become entrenched with some habits picked up years ago. Terry Creating the Hub of a Ship's Wheel.pdf
  15. Sailor1–0, How familiar are you with the Intersection feature of Sketchup? You might want to try creating models of the wheel hub and spokes, individually grouping each element and arranging them as in the final object. (Save a copy of a spoke for later.) Then explode the hub and intersect the spokes with it to define the spoke cutouts in the hub. Regroup the hub, then explode the spokes. Intersect the hub with the spokes to define the spoke socket walls inside the hub. Delete all of the spoke components except for the parts that lie inside the hub. Explode the hub and delete the surface areas inside the spoke sockets. If the work is done carefully, the hub now is solid volume with the spoke sockets arranged where they need to be. If needed, recreate the spokes from the copy and insert them into the hub. The process is somewhat complicated but straightforward. I can provide a PDF with images of the key steps if that will help visualize the process. Terry
