Although I'm still working on my scratch-builds, I got started on this recently. I received the NRG Half-Hull Planking Kit as a Christmas gift. I'm looking forward to building it and learning a lot about planking a curved hull in the process. I'm also glad that the result should be relatively easy to store, display, and transport, as I don't have a ton of room. Given work, I will probably be building this pretty slowly.

 

As can be seen, the kit is pretty straightforward in terms of components. Overall it looks like a nice kit, and the instructions are quite thorough, which I appreciate.

I'm still waiting on getting a foam building board, so nothing is glued yet, but I've sanded off the laser char and removed the basswood parts of the model's backbone (keel, stem, etc). In general, the parts fit together well with minimal sanding, although I'll have to do a little more shaping where the keel rises slightly near the stem. The keelson slots fit the frames well.

20240107_225239.thumb.jpg.7f792b1432f85de7d05dbb70ed644d7b.jpg

 

However, there is a slight issue with the fore keelson, and I thought I'd ask for advice before proceeding. The slots in the fore keelson don't line up with the markings for the frames on the plans.

20240107_225249.thumb.jpg.82bac67676438a5dfc9a7bc52ca90986.jpg

 

I see two main ways I could deal with this. One would be to trim the end of the fore keelson so it aligns better with the frame markings--more or less like below, although there the fore keelson is propped up above the other parts.

 

20240108_003932.thumb.jpg.d2b13fade9f5502b302fbb05f595d060.jpg

 

That said, if I do this I'll be throwing off the fit of the stemson and of the fore keelson against the stem and keel, which will require a good bit of shaping to correct.

 

The other option would be to simply leave the fore keelson as it is, and cut new frame slots into it. The frame slots will need to be extended anyway. And while this might leave some frames with less sturdy of a connection, I don't know if that would be a serious problem given that everything will be attached to the building board.

 

Comments and suggestions are welcome! I'm looking forward to learning a lot with this kit.

A tiny bit of progress:

 

First, I ended up trimming back the aft end of the fore keelson so the slots better align with the markings. There will still need to be some shaping, as the distance between a couple slots doesn't quite match the plans--the aftmost slot on the fore keelson is especially off--but it should work better now.

20240114_230030.thumb.jpg.f0fd2b2185aa9b9cf72545977efe1f67.jpg

 

I also finally got a building board. I had originally planned on going to an office supply store a short walk from home, but it closed unexpectedly while I was away. I eventually found some in a target. It was only 1/8zinch thick, so I doubled it up. I then trimmed my plans to the right size. I still have to glue them down, but I'm ready to start on the rabbet.

The rabbet was not as difficult as I thought it would be (unless I've actually ruined it). The instructions were fairly detailed, although some detail photos are a little blurry. I also checked Toni Levine's original build log, as well as a lot of other build logs, which were very helpful in making sure I understood what to do.

 

First things first, I used a compass to mark 1/32 of an inch on the keel, keelson, stem, and the back half of the fore keelson. I found it helpful  to lightly press the compass into the wood to mark out a groove I later drew over with pencil. I then drew out the approximate curve as the rabbet narrows along the fore half of the keelson and eventually disappears on the stemson.

20240115_233040.thumb.jpg.ec502cdba76152e153abc70c568239c4.jpg

 

20240115_233118.thumb.jpg.8e2252c146a90b83f638073d363cdeea.jpg

 

Then I began to carve the rabbet on the keelson. This cut will be hidden by planking, so I figured it was a good opportunity to try cutting the rabbet with an exacto blade. It worked all right, but was a bit uneven and had some slight gouges. Sanding it a little smoothed it out, though. I found it easiest and most consistent, as I moved ahead with the keel, fore keelson, and stemson rabbets, to use the knife for initial carving but to purposely leave space, and then to finish it with sanding. The long flat parts--keel and keelson--were best sanded against a simple sheet of sandpaper placed on a flat surface, which seemed to work well to get a consistent angle. I just had to make sure not to sand away the keel's slight rise at the bow, or after the aft marking. Meanwhile, I used sanding sticks for the curved parts.

 

As can be seen, I was soon finished except for the stem, the trickiest part of the rabbet to make.

 

Aft detail showing end of rabbet:

Bow prior to making the stem rabbet:

20240115_235325.thumb.jpg.1ae07b9d25cb2a2fd890fd9793aa94e0.jpg

 

For the stem, I started by marking where the stemson rabbet disappears. Above that mark, I cut a mortise (essentially a right-angled cutout). Below it, I used a combination of the exacto blade and sanding sticks to shape a curving rabbet, which reaches a 45-degree angle by the time it meets the keel. Below you can see the results:

20240116_000551.thumb.jpg.dc36bb9e539d6f80aa9c06dcb915cb08.jpg

 

And here's the complete rabbet. Hopefully I haven't somehow ruined it--the whole time I was carving it, I somehow had Elmer Fudd singing "kill the wabbit" to the tune of "Ride of the Valkyries" stuck in my head. Weird associations the mind creates!

Next up to glue down the backbone pieces.

Very nicely done.   I have this kit on the shelf and I am looking forward to getting started.   
 

Have you thought about how you will cut the slots for the bulkheads deeper yet?

Thank you! I think I'll just carefully carve them out with the exacto knife after the the keelson is glued to the keel, as the instructions suggest. I briefly considered extending the notches on the bulkheads themselves instead, but the plywood is really tough to cut, and in any case I need to move some keelson notches slightly to the side when extend them for alignment.

Work has been pretty hectic lately, so very little has progressed on any of my builds. A week ago or so, I glued the keel pieces together on the building board.

20240128_232533.thumb.jpg.8dde1eeea260d8ba52f8f3c00ce49f4d.jpg

 

And yesterday, I started deepening the notches. About half were very easy to cut out with a sharp exacto knife, but the other half were a lot harder and the building board took a few stabs. I think there may have been glue at the spots I was cutting there, which would be something to look out for. I was also able to adjust some of the notches to better align with the lines on the plans. I should note that the D frame lines on my plans are a bit wider than the other frame lines, so it will be a little tricky to align.

20240129_000454.thumb.jpg.9847b8e7a5e21da0d24665da9459ade6.jpg

 

One question that I haven't seen explicitly addressed in the instructions or other build logs: do the notches only get extended on the keelson, or also on the fore keelson, too? I already extended one of the notches on the fore keelson, but am debating how much I should extend the other two if at all.

20240129_000506.thumb.jpg.281738cbf48b67dae24e75bdc9b773e5.jpg

 

Finally, I made another order at Modelexpo, which included a sheet of 1/32‐inch-thick cherry (seen below with a comparison to the basswood sheet). I'm hoping to use it to plank above the wale to create a nice contrast, although the cherry is more heavily figured than I expected, so getting consistent planks may be a challenge. If I can only get a few, I might limit the cherry to just the quarterdeck or something.

Regarding the notches in the fore keelson, I think the notch needs to allow for a smooth transition from bulkhead into the rabbet for the planking.  You will need to adjust that notch accordingly based on how the bulkhead fits.

Thanks! So I think it would make the most sense to cut the notch nearly to the rabbet, with the understanding that the bulkhead will be beveled during fairing. I'm wondering if I should try to pre-bevel the foreward bulkheads a bit, although that runs the risk of really messing up the fairing.

Posted (edited)

It is easy for me to offer an opinion since I haven’t started mine, but I do think it make sense to start the beveling of the forward bulkheads before they are attached.   It will be impossible to file or sand with a forward motion after they are attached because you run into the building board.

It's been a while, but I was finally able to make progress!

 

First I extended the fore keelson notches:

20240215_205635.thumb.jpg.7b0691de563bcd2e4e132fd219d94477.jpg

 

Then I attached the frames.

20240216_142532.thumb.jpg.a65f1630dc2571a5597ffb8fcd47760f.jpg

 

After getting the central frames in place, I realized that frame 2 somehow ended up out of alignment, tilted back a little. I was able to unstick it with rubbing alcohol and reglue.

 

Then I began adding the supports. Some took more sanding than others to fit, and some were too short. While the instructions say you can add a shim, I ended up just making new ones in the correct length from scrap. As can be seen, I used rubber bands to clamp while gluing--first doing every other frame, and then running the bands across longer stretches of frames.

20240216_164706.thumb.jpg.760f79619b5d4098558d05f199f54fac.jpg

 

20240216_225431.thumb.jpg.d1ab21ed65a8e78fd96f70d2c9e8e2b4.jpg

 

It was a little tricky to make sure that I'd be able to mark at least one side of the wale on each frame.

 

Then I began adding the frames at the fore and aft ends. One frame chipped a bit, so I added a filler:

20240217_112431.thumb.jpg.788471c4395e7cef123ebc448f565038.jpg

 

Following the instructions, I marked the bearding line and sanded down the deadwood appropriately.

20240217_122726.thumb.jpg.a18dee932baac8af419cf0fe2e08c1f0.jpg

 

And here's how I cut the keel rabbet under the deadwood, which should be a 90-degree notch rather than a V-cut: (note the keel is on top in this photo)

20240217_183151.thumb.jpg.a6b55eb0ded9d0998d14484f5884a85b.jpg

 

I've been adding fore and aft frames. I just have a couple to go at the bow, and several at the stern.

20240218_114524.thumb.jpg.bcace4fb7a524787ad875886583f0387.jpg

 

I'm glad to see that it's looking a lot more like a ship now!

I finished the framing.

 

The bow was a little tricky, requiring extensive shaping in order to get the frames to follow the rabbet. I found that the plywood sands pretty well, but it tends to crumble when cut, which was a bit tricky to deal with. First I cut a notch for the 5a frame, then added it.

20240218_231220.thumb.jpg.e4ef8228db552184914caabbd0d8e77d.jpg

 

20240218_231546.thumb.jpg.7c490e6d349a9b61e39bf03ef384a0c4.jpg

 

Then a further frame that just sits on the stemson. The instructions said to add another piece ahead of it to run directly up to the rabbet, but I didn't have the space.

20240219_112735.thumb.jpg.e4129c80ff7b1b22daf4c2ef14c759fd.jpg

 

As can be seen, I also ended up angling the spacer due to the serious curves in the hull form at the bow.

 

The stern also required some shaping to match the rabbet. There was no space for a spacer between G and Ga.

20240218_231719.thumb.jpg.88d7bfa805df35a6c3efe76debf3dbbc.jpg

 

Instead, the spacer went between Ga and Gb.

20240219_112729.thumb.jpg.ca739f48e29a70e44140db472801dafd.jpg

 

Finally I added H. I nearly had a heart attack (well, that's an exaggeration) when I noticed that the aft part of H is not supposed to be sanded, after I had already shaped it to match the rabbet. After looking at Toni Levine's log, I realized that the H frame should indeed be shaped to match the rabbet, it just shouldn't be sanded when you're fairing. In general I recommend reading other build logs alongside the instructions for complex areas like the stern. I was then able to glue the transom to the L-shaped piece and glue them in place with an angled spacer.

20240219_140717.thumb.jpg.3548558c9f46aced7baebbcf92186b4e.jpg

 

The instructions and most build logs aren't very clear about how the transom is oriented, so here's another view of how I did mine. The key is that the curved end should be facing out, with the narrow part at the top.

20240219_140723.thumb.jpg.b016fe811f1f8f5a75f16ecd884f80b4.jpg

 

With framing complete, it's becoming clearer how the hull will look:

20240219_140750.thumb.jpg.0c65f07992b52aae0fee11ee4c98fdce.jpg

 

Next up, to figure out the topline and then fair the frames.

Posted

Shaping the topline was easier than I expected. First, I used a square to mark it. I started with a pencil, but changed to just marking it with an exacto blade, as it was more precise. Every frame needed to have something trimmed, some of them quite a bit, and none of them needed to be built up.

 

As I mentioned, I found the plywood to crumble easily when cutting with an exacto blade, so originally I was going to just sand. This would have been quite a bit of sanding, though! Instead, I decided to try my razor saw. It worked perfectly and cut very cleanly, and the blade readily followed where I had earlier scored the frames.

20240221_001123.thumb.jpg.32a273cd5bdb4bb13c82105d4fb495b0.jpg

 

There were a few areas near the bow and stern where I needed to use a smaller blade. I was able to use the tiny exacto saw blade to cut there.

20240221_163640.thumb.jpg.decaed1c4a2f01a842e0a9e5a0f19015.jpg

 

In general, the plywood handled the sawing very well without any problems, and I soon had all the frames cut to the topline.

20240221_095758.thumb.jpg.287c33c3c92e3e96d5764ae7686c6bec.jpg

 

Then I sanded, using a long, flexible sanding stick. It worked really well, except that the transom required quite a lot of sanding, so I ended up simply sawing along the mark there before cleaning it up with sandpaper.

20240221_164044.thumb.jpg.61c925bdbdc4ad67e7c0d1b44da4d399.jpg

 

With that, the hull is ready for fairing.

20240221_164101.thumb.jpg.9f7e2b54e9b5a0996edc89ae7a2d7eb7.jpg

Just a brief update. As other logs have noted, the frames require quite a bit of fairing, and I've been working on it a bit at a time. It's neither the most exciting work, nor the most interesting to photograph, but I definitely want to get it right. I've been using 150-grit sanding sticks, and for a time just a sheet of 100 grit sandpaper in order to sand some areas that need a lot removed.

 

20240228_125156.thumb.jpg.9ca360b6090a3c2dcc4a2963b87d8017.jpg

 

I still have a lot to go. As can be seen by the char, some of the frames have barely been sanded, and I will probably have to build them up a bit. Other frames, especially B, were very prominent and have been reduced by quite a bit. The bow takes a lot of work to fair because a ton of material has to be removed, but (so far, at least) it hasn't been complicated. The stern is a different story. The idea behind having so many frames there is to provide a lot of surface area for a complex shape, but it requires a lot of sanding. It's also tricky to get without accidentally sanding the aft edge of Frame H, which the instructions warn against doing because the counter will be placed there (and presumably faired afterward? The instructions are not clear on this).

 

In any case, I still have a lot of sanding ahead of me. I can see why people like using dremels for this!

Things have been extremely busy around here, and I have not been able to make nearly as much progress as I would have liked on the half-hull.

 

Fairing continues, very slowly. Here's my current progress.

20240321_003430.thumb.jpg.0f16c94add46f713defe27d4066ec788.jpg

 

The B frame still protrudes too much, despite a great deal of sanding. I've ended up needing to build up the C and E frames, and may need to build up the D frame a little as well.

20240321_003456.thumb.jpg.a20cec20041bb580474009f4887a019e.jpg

 

Beyond that, the bow and stern have also both given me some trouble. The bluff bow is requiring quite a bit of shaping. I've had difficulties with using battens to test fairness here, as the battens keep breaking around the sharp curve. That said, I think I'm getting there at the bow.

20240321_003548.thumb.jpg.53ed6c278105862d7f7b5bb93ddeb449.jpg

 

The stern is another story. The dense stack of frames there has some really major differences in height between frames. As can be seen, some of the frames are low enough that they've barely been touched by the sandpaper. Parts will need to be filled in with some fairly large pieces of scrap basswood. I'm also still not really sure when to add the counter--I think I'm at about the point where it can be added, but maybe the stern needs to be more faired first?

20240321_003524.thumb.jpg.317f6352a658a1abfd3bebc370505a56.jpg

 

If anyone has any advice on fairing, or has noticed anything that I'm doing wrong in the photos, I'm all ears! I'd love to move on to the next step and actually start planking, but I know a poorly-faired hull will cause all sorts of problems later.

I cant help with the counter as i havent built this ship but on my AVS model i had to sand a lot and add strips to shim out the bulwarks, just like youve been doing.  the sweep up to the stern in your last picture is supposed to be sanded diagonally, a mirror image to the prow.  Probly you know that.

i wonder if this design would have benefited from having an extra frame along the deck midline.  then the bulwarks could have been “D” shaped instead of their S shape which always looked unstable to me.

but regardless great job i am following with interest; this ship is on my to do list

I can’t say that I see any wrong but I do think your stern could probably use some more fairing. I added the counter after I had faired the stern further (which I believe @tlevine did the same looking at the original build log).

 

I used a bunch of Emory style boards (from the cosmetic section of a general retailer) to do a lot of the fairing and recall really having to work a lot on both the bow and stern. You’re doing a good job!

Posted

Thank you for your helpful comments! I'll definitely fair the stern more before adding the counter, and I'll have to try some emory boards. @VTHokiEE, your half-hull turned out great and your log has been helpful for thinking about the build. @CiscoH, your sloop looks fantastic. If you do the NRG half-hull, do you think you'd use holly again?

 

I think part of the reason I've been so slow with sanding is that the plywood dust seems to set off my allergies more than basswood has. Wearing a mask and sweeping up immediately after sanding helps, but sanding indoors still gets dust everywhere. Hopefully the weather warms up enough soon that I'll be able to sand on my balcony instead.

Dust can trigger my allergies as well - I tend to use a mask as well as a shop vac positioned near the sanding zone to try to keep the air clear. 
 

I think there are some other air filtration units that can be effective for this as well, but having the shop vac on (and wearing ear protection) has helped a lot.

Slowly but surely, I'm getting closer to finishing the fairing. I've been barely able to work on it lately, but today I was able to grab a few moments and sand out on my balcony in the sun, so that I wasn't leaving dust in the apartment.

 

I decided to use a bit of chart tape to check on the fairing. There are still some high spots and shims needed, but it's getting close.

20240408_185639.thumb.jpg.c2fd2c92ff7de89ee9365df8fdb5d3c8.jpg

 

I'll either need to shim frame D or sand down frame C (to the right, which was already shimmed).

20240408_185721.thumb.jpg.575a38f01ee87387e9c03b5e66ada695.jpg

 

At the bow, I initially thought I would need to shim frame 4 (and possibly 3, to its left). When I used the chart tape to check at other placements, though, I found that the real problem is that the upper part of frame 4a needs more sanding.

20240408_185739.thumb.jpg.81517c1dd778a7c1d04107ce3369ddf2.jpg

 

I also decided to start shaping the counter to get a better grasp on the curves at the stern, although I still have a bit more sanding to do there. I beveled the edges and placed it, but I'm not sure what I'll need to do to get a better fit (besides sanding more, of course). The corner of the counter stands way out from the frames.

I think I'm nearly there with fairing?

20240418_093737.thumb.jpg.004d84b95f1ef2a03b73a8aa1829d5f3.jpg

 

Toward the bow, adding some fillers on frames 3 and 4 was useful. Testing with a coffee stir-stick batten seems to suggest that I need to do just a little more on the lower part of the 5a and 5b frames right at the bow.

20240418_093252.thumb.jpg.efac8b61f8ff10e21f3e2db99ce6b358.jpg

 

At the stern, I ended up carving some filler pieces (as it was a very complicated curve) to fill some of the major gaps around frames.

20240418_093310.thumb.jpg.e11c4dcc285a3caea0b26d0ce181dd4a.jpg

20240418_093319.thumb.jpg.87d90d3caeb97ac9e69f7ddfd23dfb66.jpg

 

As can be seen, there's now a lot more surface area for the planking here.

 

However, I'm not sure if I need to fair this area significantly more? I'm having a hard time visualizing how the planks will transition into the rabbet. It seems like a very complex series of curves in all directions in this area, and I'm having a hard time visualizing it from photos elsewhere.(Test with coffee stir stick below.)

I think it's finally faired, but I'm still not totally sure on the stern.

 

As can be seen, the bow now takes a smooth curve:

20240418_221914.thumb.jpg.ce8fbfcccea6037043309f9442cd2b5d.jpg

 

I've faired the stern more and I think it's looking better, but I still have to admit that I have a hard time understanding what it should look like. 

 

This, for instance, would be for a strake that ends against the counter, near the wale. I'm not sure if it's still bending too much upward at the stern.

20240418_222052.thumb.jpg.921edadf277476e19bc52f0528236784.jpg

 

There's still a bit of a bend like that further down for planks that would end at the rabbet, as well:

20240418_222230.thumb.jpg.f2082ba59673f91ebcde12af5f6b3d4d.jpg

 

Do I still need to take more off? At this point I've sanded so much that I'm worried about taking too much off, but I still can't figure out if this is fair or not. Any advice would be appreciated!

Forgot to mention: I've also reshaped the counter. As far as I can tell, something like this should work. Although now I should probably fair the aft edge of the H frame a bit more....

The garboard strake is on!

 

I marked out the wale and the location of the garboard's top edge with chart tape. It needed a little adjustment after these photos, but not much.

20240419_095037.thumb.jpg.87438a9c76acb2e1c5232b08710a8884.jpg

 

Then I removed the tape that was protecting the stem and keel. In the future I should use actual masking tape, scotch tape didn't do a great job of withstanding accidentally sanding and tended to rip rather than to come off in one piece.

 

I marked out the garboard strake, starting with the aft plank, on tamiya masking tape as per the instructions.

20240420_185428.thumb.jpg.ddab3c0d2e85076ee67439ec8a822461.jpg

 

The sawtooth aft was a bit exaggerated, and the plank took some sanding to finalize the shape. Although the instructions don't say to soak the plank to bend it, I did it anyway to reduce the stresses of twisting it so much.

20240420_191212.thumb.jpg.a5a17c2c2a06a8f59bec6f5580da66e5.jpg

 

Then I glued it in place, and repeated the process for the fore plank. As can be seen, the aft plank turned out ok. The rabbet was perhaps a hair too shallow.

20240421_202759.thumb.jpg.49d329f37997eb49755827a630fb353f.jpg

 

As for the fore plank, I think it's low enough at the bow to avoid the "smiley-face" problem. It also didn't sit well at the bow rabbet, as it approached it at a shallow angle. I'm debating whether to try to remove it to sand down the inner side of the rabbet or something so that it sits better.

20240421_202820.thumb.jpg.f825a309f72c36f19216d92cf86778d9.jpg

 

Overall, though, I'm excited to finally be making planks. Fairing the hull took a lot longer than I had anticipated.

Thanks! It's been hard to find much time, but I've now added the broad strake.

20240511_110855.thumb.jpg.fac3b3ec411475883c2cf34dc201a20d.jpg

 

I started with the middle plank and worked my way out. There's only a little twist in it, so I was able to simply glue it in place with clamps.

20240510_200036.thumb.jpg.714fbd6658289d2652603985aad6319a.jpg

 

20240510_201716.thumb.jpg.5fb0862cb00509114107d683e465dbdb.jpg

 

In contrast, the bow and stern planks twist quite a bit, so I soaked them and clamped them in place overnight. I did the stern first.

20240510_214204.thumb.jpg.f5e578390d893b0a0ae5405cb09bcd4f.jpg

 

Shaping the planks is, so far at least, a lot of fun.

20240511_105711.thumb.jpg.0d3eee7e88d95657add377edffbdb0ef.jpg

 

Then, the bow. One issue I've had is that, for these first strakes, it's very hard to fit them into the stem rabbet because they approach it from a nearly flat angle. If I did this again, I might try to carve or sand a smoother transition into the rabbet here.

20240511_101906.thumb.jpg.3b3688ce60640414b2c218672482c307.jpg

 

20240511_110836.thumb.jpg.6d9f625b5616d43bd3f8ba09789573e2.jpg

 

I think I'm avoiding the "smiley face" effect?

 

It's very cool to see how the strakes curve along the length of the hull.

The planking definitely needs to be sanded, and there are some very slight gaps that are visible when held up to the light. If I fill these with a mix of sawdust and glue, will they show up when I finish the hull?

Picking this back up, I've now defined the runs of the belts. This took me a bit of thinking. I found the instructions on this point a bit confusing when reading them, but they were clear enough once I started actually laying things out on the hull. Note: when the instructions say "Measure inbound along the lower edge of the counter the width of four planks 0.75"," what it means is to measure from the aftmost lower mark of the wale, inboards toward the stempost.

 

Here we can see my planking bands marked out in chart tape.

20240601_203110.thumb.jpg.a97b6343604ee2bd7a2a5a97f5703541.jpg

 

I think I've managed to avoid too much of a "smiley face" at the bow.

20240601_203128.thumb.jpg.220e93ae0cb2ba1a33485ba3c48aa3cb.jpg

 

I've read that you should consider the run from multiple angles. I found that sighting along the length of the hull was helpful for finding a few high or low points and correcting them. Here are some other angles.

20240601_203147.thumb.jpg.00f475649d506d311989432625620ad9.jpg

 

20240601_203153.thumb.jpg.6c07ece8c44e940af65225af3926dcfa.jpg

 

20240601_203219.thumb.jpg.7a8aff0532e6df514bee699073a3a878.jpg

 

The instructions suggest that, once you're happy with your belt runs, you should let it sit overnight and come back to it with fresh eyes. That's what I plan to do, although I've marked it in pencil in case the chart tape comes loose overnight.

Posted (edited)

I'm glad I let it sit overnight, because the next morning, the aft run of the belts didn't look right to me. They were a bit too high and would have led to some very odd plank shapes, including a notable bottleneck in the upper belt. So, I adjusted.

20240602_163529.thumb.jpg.8e76ca1a3654aaf91463d56bd5e8ccc0.jpg

 

Satisfied, I marked the belts in pen.

20240602_165057.thumb.jpg.0f8975072c37b85943a3d11b4603dcb4.jpg

 

Following the instructions, I figured out the plank butt joint locations. Once again, this was hard for me to understand when reading it, but much easier to grasp once I took the advice to draw it out.

20240602_200814.thumb.jpg.215fb4c13726c59515e1385e53af7134.jpg

 

The drawing is pretty crude, but it worked. Well, mostly. Try as I might, I couldn't work out a pattern that satisfied the proper distances between joints. It was easy enough to not place a joint on the same frame for two consecutive strakes, but the rules about distance between joints (at least 1.25 inches apart on consecutive strakes, and at least 1 inch apart on strakes separated by another strake) were extremely hard to follow, especially as the frames are an inch apart. Then I noticed that the example in the instructions seems to have fudged it slightly (or I'm misunderstanding something, which is entirely possible) such that a number of joints on adjacent strakes fall one frame apart, under the 1.25-inch rule. I ended up simply following the example given in the instructions.

 

The stealer was also very confusing to me. I marked what I think is the correct location for it, but I'm really not sure. In any case, it's at the top of the first belt, so I have some time to figure it out.

20240602_203621.thumb.jpg.15f2126ed80db8fd73ed708b9290bd98.jpg

 

Finally, I've begun planking the first belt. Very exciting!

I've completed up to the third strake on the first belt. I have to admit that I was a bit worried about how much I would enjoy the kit earlier when I was stuck in a seemingly endless fairing process, but I am having a lot of fun planking! So much so that I haven't actually taken any photos of the process itself, which maybe I should remedy. I've just been using tamiya masking tape to mark the planks, cutting them oversize, and carefully shaping them to fit. It's a very calm, thoughtful process, and I can easily do a plank in 15-20 minutes or so. I've only had to redo a few. So far one of the main challenges has been remembering to draw the caulk on the sides of the plank before gluing it down.

20240608_105105.thumb.jpg.86cca668ab357582ab64e511a2b958a4.jpg

 

20240608_105037.thumb.jpg.6637a108f5ac740019cc48b8d57f3984.jpg

 

For whatever reason, there was significant color variation between some of the 1/32‐inch basswood sheets. I'm actually liking the mix of lighter planks among the darker ones, I feel that it brings more attention to the fact that each plank is unique and individually shaped.

 

20240608_104931.thumb.jpg.10c369b80a7514ac70178b389bdfab95.jpg

 

20240608_105004.thumb.jpg.c3861a05466dfa3d9b3d1608f8389315.jpg

 

As can be seen above, I don't think my bow planking was all that precise, but I can see it getting better as I get more practice. It also probably helped to lightly sand back the inner edge of the rabbet under frame 5 so allow a smoother entry of the plank.

 

20240608_104908.thumb.jpg.97ede16f8309482814f3add07b602d5a.jpg

 

Now that I'm gearing up for the top strake in the first belt, I need to actually figure out how to shape the stealer and surrounding planks.

Posted (edited)

So, here's how I've been shaping the planks. This is one of the two methods shown in the kit instructions. I haven't used the other, compass-based method that's included in the instructions because I don't have a compass and it sounds like it adds more steps where things can go wrong, but perhaps other people have found it simpler. The below is just what's worked for me.

 

First, I use Tamiya masking tape, which is semi-translucent and allows me to see my markings on the frames, to mark 1) the bottom edge of the new plank, 2) the fore and aft ends, and 3) the markings for plank width on each frame.

20240608_122029.thumb.jpg.9c3f784a2f0f06b26f4b775fcd3fe24b.jpg

 

I then transfer the tape to the basswood sheet.

20240608_122130.thumb.jpg.07ca79719c479e26cd3732fd4d191525.jpg

 

I "connect the dots" into a more-or-less smooth curve. A set of ship's curves would probably be most useful here. I use a very cheap french curve, or sometimes a ruler, to connect up to three width markings at a time. Keep in mind that the plank will be smoothed out with final shaping.

20240608_122239.thumb.jpg.af6a2a6756d09b2c6db4ae732fe1918b.jpg

 

I then cut out the plank with a sharp exacto knife, leaving a bit around all the edges. I like to leave the tape on until the very last steps, as it allows me to draw markings for where I need to remove material and where I need to NOT remove material.

20240608_122538.thumb.jpg.2e8f8605eb1eb943769219c302d32dad.jpg

 

Then, i do an initial test fitting, focusing on fitting the plank to the strake below. This is just done by hand, but the clamps were necessary to be able to take photos. As can be seen, there are a number of gaps, so I need to remove material at the points where the plank contacts the strake below.

20240608_122631.thumb.jpg.bf4186dda785ed152346b8543107d22e.jpg

 

After shaping with the exacto and sandpaper, I did another test fit. That looks much better, but there's still some shaping to do.

20240608_122913.thumb.jpg.b82ba79e6587f28e8dcf3f6bebd206b7.jpg

 

It's a good thing that I left a bit of meat on the edges of the plank, because when shaping it, I accidentally cut off a little too much at one part. Thankfully, the plank was oversized enough that I was able to just reshape the bottom edge to get a perfect fit, leaving the plank still wide enough.

 

With the bottom edge ready, I moved on to the top edge, marking where I needed to remove the most material and not. I stopped clamping for the top edge because the clamps would have blocked the view, so in some areas the plank isn't right up against the frame, but you get the idea.

20240608_123814.thumb.jpg.6e1883f81bdb713b3a4db04071a99471.jpg

 

I like to use the exacto knife to shave down where I need to remove a lot of material, and then sandpaper for final shaping and to make sure the plank forms a smooth line. Once I get it just about there, I remove the tape for final shaping, as sometimes the tape can get in the way. I try to shape the plank down to where I can just barely see the edge of my width markings on the frame, as can be seen with frames A and DF below. Due to the curve of the hull, the plank isn't fully up against frames B and 1, hence why they look like the plank is below the marking there.

20240608_124155.thumb.jpg.668fa7cb223800b315fb72be4a58ce23.jpg

 

Finally, I moistened the plank and clamped it to dry. This isn't always necessary, especially for planks in the middle of the hull that are minimally curved. But I find that the plank always fits best for gluing when it's been given the appropriate twist/curve. The less you need to push the plank into shape when gluing, the better.

20240608_124353.thumb.jpg.a6625a67cfe9c12589fb65335bdb0561.jpg

 

So now I just have to wait a few hours for it to dry (I'm in no rush). Then I'll draw the caulking on the edge. A note about this: when I draw on the caulking, I always hold the pencil to approach the plank from the inboard side. In the photo below, the right side of the plank would be on the inside of the hull, and the left side is the exterior. I usually slip and end up drawing lines on the plank, but this way they're on the interior and won't mar the surface.

20240608_132119.thumb.jpg.357a0b3daf5913b05a0d7b3d7b438879.jpg

 

Finally, I'll glue the plank in place.

 

This is all obvious stuff to the more experienced modelers out there, but I wanted to show it in case it was helpful for anyone. There have been plenty of times where I've been really helped out by seeing someone else's step-by-step instructions, even for something basic, on other build logs.
