Very nice work!

This post is about paper modeling rather than wood, but it may be helpful. Basically, to figure out the bulkhead shapes, you need to take the forms given in the section drawing and mirror them (as the section drawing shows the aft half of the hull at left and the fore half at right). For the central spine, the bulkhead slots would be located at the section lines (the vertical lines running through the side view). The spine would look more or less like the side view, but it would only extend up as far as the lowest deck you're modeling, and you'd have to decide whether it will include the keel/stem/sternpost or if that will be added separately. The NRG has a useful drawing on interpreting lines drawings that may be helpful: https://thenrg.org/articles/interpreting-line-drawings I'd recommend checking out scratch build logs to get a sense of the process.

Thanks, @wefalck, @Paul Le Wol, and @Kenchington for sharing your insights! I think I will go with a very simple pump handle, as even the stowed lever looks like it takes up too much space for a small cockpit. As for the pump design, it seems like I have several plausible options, so I'll have to think some more about what would look best and be feasible to model. Thanks again! If you had asked me three years ago for my thoughts on late-nineteenth century workboat bilge pump design, I would have looked at you like a crazy person. Now I feel like I'm starting to learn enough to actually have some thoughts on the topic (although there's still a lot more that could be learned).

Welcome! Very nice work on the Beagle (despite the kit's issues). I hope you'll do a build log for your next model!

Nice work and good repair!

Thanks, all! Planking continues, slowly. Meanwhile, I’m thinking ahead to finishing up the cockpit. A key aspect of the boat’s equipment that is not included in the kit is the bilge pump. @Kenchington’s build includes a very interesting reconstruction of what this might have been like, but it’s worth noting that there are very few direct sources on this. The bilge pump does not appear in Chapelle’s plans, nor in the drawings of the sloop Ranger, nor have I been able to find a clear photo of it. The best I’ve been able to find is a photo of a replica Muscongus Bay sloop under construction in the 1970s, in which there is a hole in the cockpit floor next to the centerboard case, presumably for a bilge pump, but the pump itself is not shown. Most of the discussions of pumps on MSW focus on those used in larger ships, not in small workboats. So, some research is needed. What options are there? @Kenchington’s build includes an informative discussion, linked to below, in which he ultimately decided that an elm tree pump, discharging into a bucket in the cockpit, makes the most sense. This seems very reasonable to me, but 1) he hasn’t gotten to the handle yet, so I’m not sure what that would look like, and 2) I don’t want to just blindly steal from his ideas—at least not without learning a bit more about workboat pumps in the era first so I can better understand what I’m looking at. As I mentioned above, Chapelle’s plans of the Muscongus Bay sloop don’t show a bilge pump. In fact, I found very little about bilge pumps in most of his books—they’re barely mentioned in American Small Sailing Craft or Boatbuilding. American Fishing Schooners does include detailed drawings of wooden and iron pumps on pp. 571-582, but I’m not sure whether those designs would have been used on the much smaller sloop I’m modeling. Below, images from the book of a wooden pump and a diaphragm pump—as Kenchington suggests, the latter likely came into use a bit later than the period this model is supposed to represent. A few plans included in American Small Sailing Craft do depict pumps, although not in much detail. Most relevant, perhaps, as Kenchington notes, is that the construction drawing of a Friendship Sloop on page 273 shows some sort of pump in the cockpit, apparently emptying over the coaming, but it’s not clear what side it’s on, what the handle would look like, or whether it would be a round or square cross-section. His plan of a Quoddy Boat on page 263—especially relevant as it’s from Maine in the same time period as my model, although a rather larger vessel—also shows a pump, located just forward of the mainsheet, with an apparently round cross-section, although again the handle isn’t shown. Chapelle’s The Migrations of an American Boat Type (1961), a booklet on the development of the sharpie, does include the following photo of a square pump box on page 151, and the plans earlier in the book show that there was one on each side of the hull. (This detail is shown in Paul Le Wol’s excellent scratchbuild of a North Carolina Sharpie, by the way). The square shape is intriguing, but once again no handle is depicted. Looking beyond Chapelle, I also had a hard time finding much information. Nearly everything that I found was written with large ocean-going ships in mind, not small workboats. Skimming through Inshore Craft: Traditional Working Vessels of the British Isles by Basil Greenhill and Julian Mannering, though, I did find the following interesting depiction of a pump in a small Ardrishaig Open Line Skiff (pg. 18). The handle appears to be a simple loop rather than the more complex lever that appears in other pump depictions. An article on the Sgoth Niseach in a 1998 edition of Ships in Scale magazine shows something similar, but with a square- rather than round-sectioned pump. (Of course, these are from the UK, not the US, so I should take them with a grain of salt). Finally, searching on the Penobscot Maritime Museum site, I found this interesting galvanized pump. Unfortunately, it’s undated, although my understanding is that metal pumps are more likely to be from the 1900s and hence a bit later than my model. Source So, what can be made of all of this? There are two main questions that I have for my build. First, basic design. It seems that wood is the most likely material for the pump on a small workboat in c.1880s Maine, but I’m not sure whether a square or round cross section would make more sense. The round cross-section pumps were apparently made by boring out an elm tree, whereas I’m assuming that the square-section pumps were made out of planks. The latter option sounds to me like it would be cheaper (planks being widely available), but I’m not totally sure and would appreciate any suggestions. Second, the handle. While the big lever would certainly be easier to use, it takes up a lot of space, and this sloop has a pretty small cockpit. So, I think the options are either that 1) the pump uses a lever handle but the lever and associated mechanism can be removed, so as to not take up too much work space, or 2) given that this is a pretty small boat and the force to lift the pump would be relatively low, there’s no lever, just a simple crossbar (as on the galvanized pump above) or a loop handle). At the moment, I’m leaning toward the simple crossbar handle, but I haven’t decided on the square or round pump cross-section. Any thoughts or suggestions would be appreciated!

Great work on the pilothouse!

Very nice work!

Welcome!

Very minor update: I liked the way the bolts on the capstan barrel assembly turned out, so I decided to do the same with the capstan step bolts. Rather than have them go all the way through, these are fake bolts only visible from the top side. I'll add pins to the lower side of the holes when the time comes to attach the step to the framing. It would be more accurate to blacken the bolts somehow, but I'm going for a more stylized look on this build anyway, so I'm happy with them looking more metallic. As can be seen, the step got a bit scratched up when I was filing down the bolts. So, I ended up lightly sanding the whole top with fine grit sandpaper and applying a new, light amount of linseed oil. Of course, it will take forever to cure, but it will be finished at about the same time as the capstan barrel. I also added a thin coat of shellac to protect the framework, the linseed oil on which has cured by now. Here's the whole assembly so far, minus the capstan bars: To cut out the capstan drumhead parts, I think I'll need to wait until I can get into the carpentry workshop to use the fretsaw there, so it will probably be a little while.

Nice progress! The black extending down from the bow chocks looks really sharp.

Thanks! I can see all sorts of ways I could be more precise. This build has been a great learning experience for me, and also very humbling. I think about how much time this single capstan has taken me, and then look at the amazing full-ship scratch builds on this site, many in a much smaller scale, with so many precise fittings and cuts. It blows my mind that people ever finish a full-ship build! It's also been very interesting to "mill" my own wood by hand. On one hand, it feels like a real accomplishment and I feel that much more invested in the model. On the other hand, it's an absolute ton of work, especially without the proper tools. Earlier I had been considering using the manzanillo for a fully-framed cross-section model, but by now I think that milling the lumber to size would be way too much work to be worthwhile, except maybe for some select parts. (Not to mention that the manzanillo's grain is a little more prominent than I would like, and I've found that the dust irritates my nose a bit if I do substantial sawing or sanding indoors.)

Very nice work! (Not just on this, but throughout the model, it's an extraordinary build.) Can the windlass rotate, or is it stationary?

Very nice work! The dockyard style looks great.

I drilled out the bolt holes next, and then gave it a final sanding. For the bolts, the ones through the whelps should be thicker than the ones through the chocks. Rather than try to exactly match the dimensions at this small scale, I decided to go for a general impression, using annealed wire in 24 and 28 gauge. Finally, I drilled pilot holes in the top and bottom, and applied a linseed oil finish. In my experience, the linseed oil will even out a bit and look better tomorrow.

The Nautical Research Journal has an article in Vol. 20, No.1 by Ben Lankford titled "The Rig of a Scow Schooner." I bought the pdf version a while ago. He mentions reconstructing typical block sizes based on Steel, Kipping, and other "standard tables." The drawing seems to include block sizes, but it's hard to tell--in the pdf version, the drawing is blurry. I've included a small portion of the image below. Assuming the numbers next to the blocks are in fact their sizes, it looks like the main sheet used 12- and 13-inch blocks, 8.5-inch blocks were used at the aft end of the main boom for the main top lift. Elsewhere it looks like 10- or 10.5-inch blocks for used for the gaff halyards, 6.5-inch for the topsail halyard, and even some smaller ones elsewhere. (This is, of course, a very rough summary based on some very blurry text, so take this with a grain of salt). The full article may be useful to you, as it can be ordered for pretty cheap through the NRG store, but you'd have to decide whether the blurry drawing is a dealbreaker. (It also includes a belaying plan and other detailed drawings, though without dimensions, that are a bit larger and very slightly clearer.)

For the lower chocks, made with a thicker strip of manzanillo, I trimmed them closer to final size before gluing. I still left them slightly oversized, though. I then sanded them to final shape. They should be slightly concave. At this point, I need to drill the bolt holes, do a final careful sanding at a finer grit, and then apply a finish to the barrel assembly. Edit to add: And here it is resting on the capstan step.

Nice work on the 3-model series! Given that you built one already, do you think you'll be kitbashing this build?

Thanks! I used an x-acto knife to pare down the excess chock material, and then sanded it down. It was a little tricky to hold the barrel assembly while carving, so for the lower chocks, I think I'll try to trim them nearly to the right size before gluing. I also sanded the top and bottom of the barrel assembly, bringing it down to the right size. These upper chocks should be somewhat rounded, as can be seen from above.

I think Syren offers internally-stropped wooden blocks, although I don't know if they're the right size. Another option would be to fake internal stropping, as done here:

Once back in Mexico City, the next step was to add an extra layer of manzanillo shaving to the spaces between whelps on the barrel. As I noted above, rather than follow the wedge method given in the instructions, I followed @Cathead's lead in making the barrel from a different wood and building it up to create slots for the whelps. He used veneer, which would undoubtedly be a better option than multiple layers of thin shavings, but given my limited milling equipment, shavings are much easier for me to make. I also cut the barrel to size. I then began adding the whelps. In the meantime, I also did a quick test with scrap and found that the shavings seem to absorb linseed oil just fine--I was worried they would be too thin and glue-saturated to do so. At this point, the assembly is slightly over-tall, and it needs to be sanded at the top and bottom to fully even everything out. Before I do that, though, I wanted to add the chocks in order to strengthen the assembly. The chocks need to be quite thin, and I wasn't sure how to go about that. I briefly tried planing down from one of the chunks of 1/8-inch thick "milled" manzanillo, but I realized it would take forever. Instead, I used a coping saw to cut a fairly thin (marked at 3/32-inch thick) strip off the edge of a length of board. Below, it's midway through planing to smooth it out. My saw blade wandered a bit and one side ended up a bit thin, but in this case, that worked in my favor. The upper chocks should be noticeably thinner than the lower ones. So, I cut off the thinner side and planed and sanded to a consistent thickness. To cut out the chocks, I decided against using a template, as my barrel assembly is a bit off from true and every whelp is at a slightly different angle. Instead, I traced each shape directly on the wood, cut slightly oversize, sanded in the bevel, and adjusted to fit. At the moment, I have the upper, thinner chocks glued in place. They're all oversized. Once the glue dries, I'll carefully shape them, and then get to work on the slightly thicker lower chocks.

Very nice work!

Fantastic work!

I'm pretty sure they're the bands. On my build, I added them at this point: They sit on the outboard side of the planks, following the sheer.

Very nice work, it's great to see this odd little vessel coming together! With the details added, I was going to say that it's really starting to look like a boat, but to be honest, I think it looks more like a floating house--I mean that in the best possible way, of course.
