    Airbrushed on a couple of coats of olive on the gun carriages and slides, then went at the hardware with Testor's Flat Steel. The US Navy kept the hardware bare metal and well greased. The gun tubes too, were kept greased and shiny.
    I never have much luck paint just the tiny thing that needs painting, so I paint it, and around it to get in all the nooks and crannies, then cut in the base color to neaten it all up.
    Unfortunately the gun tubes are painted satin black from a spray can, and I don't have any brush-on to do the above mentioned cut-in on them. The stores don't seem to carry anything smaller than quarts now-a-days, so I had to order online.
    The other guns I've printed got some paint too.

    The new tracks for the pivot guns were remodeled, printed, primed, the old ones removed from the hatches, the hatches sanded and refinished. The tracks are painted, glued in place, painted some more, and clear coated. It's a matter of painting the guns then screwing them to the hatches. Details such as tackles, eyebolts in the deck, etc, will come after that.

    When I made the boat howitzer, I modeled it based on an original in Fairfax Virginia with iron wheels. Looking at all the images from 1850's manuals, drawings, photos, and even artwork showing them in Japan; they nearly always have wooden wheels. I started thinking it was probably more appropriate for Constellation's boat howitzer's field carriage, in 1856, to also have wooden wheels. So I modeled a set, and printed a new field carriage, and today, got it painted, though it needs to be clear-coated yet.

    BTW: The STLs for these guns and more are available on Thingiverse, for free; which is about $50 Canadian

    I kid

    Jerry - Some photos of the 12 pounder (USCG) I took in 2007 at the Mariners' Museum's Monitor Center are attached. (My son is the marine sergeant at the breech of the gun.)

    I also found my old video of the gun firing and will upload it to YouTube ASAP.

    Jerry, the Dahlgren boat howitzer is an amazing artillery piece. Years ago I had the opportunity to discuss it with the "reenacting crew" in Virginia. ( This particular one was owned by the USCG.)

    There are several histoy accounts on how it was used with naval "infantry" ashore and transported in pieces across rough terrain. There was also a mount on some of the launches.

    Brings back some neat memories of my Civil War naval reenacting days. Thanks for sharing this. Without a doubt, you are the best modeler of that period, period!

    I made a copy of the file for the tracks I had made before, and remodeled tracks for these new, shorter, guns. I also made them thinner to be more scale than the old ones.
    It took more than 5 hours to print because I had to make then in halves, and stand them on edge to fit in the printer's space.
    Part of the forward circle didn't print, so I set up to reprint just that, plus a few extra pieces, just in case.

    I scraped off the old tracks on the model's fore and aft access hatches, sanded off the scars of the old tracks, and laid things out to check the fit. There's some more sanding to do, and then put the finish back on the deck, before gluing the tracks down after they're primed and painted. The bits of track hanging over the edge will be sawn off and glued to the deck across the hatch seam.

    These cannons are true masterpieces.
    I am progressing very slowly with my much smaller Dalghrens.
    I wish I had learned about this site and your work ten years ago, instead of just now.

    Doing some research about Naval Guns in the 1850's for another project led me to thinking Constellation was armed with something different than the pivot guns I armed her with.
    I decided to replace my 10 inch 82cwt pivot guns with 10 inch Dahlgren guns she more-likely had.
    The 3D model is based on Dahlgren's own sketch made in 1850, which matched a diagram of a Traversing Carriage and Slide printed in the 1852 "Instructions."
    I printed two of these 10 inch pivots, but because their slides are shorter than the guns they're replacing, I need to make need deck tracks to go with them.

    I was aboard when she came back from dry-dock in March 2011. I lived in Baltimore city from 1969 to 1989, and in it's suburbs, since. I worked on the water on tugs, a skipjack, the first Pride of Baltimore's construction, and later as crew. My best friend, who I've sailed with since we were teenagers, is a tug captain on the bridge site right now.

    When I was volunteering at the Naval Academy Museum, I got to see a glass-plate photo of Constellation on the Severn in 1879 where you can see the widened gun-port for the XI Dahlgren (port-side). The "proposed" set-up was marked on her original gun-deck plan from 1854, I put a portion of it here.

    Jerry, I found this in the US Navy records:

    Recommissioned on 25 May 1871, she took midshipmen (also classed as โ€œnaval cadetsโ€ at varying periods) on their summer training cruises for the next twenty-two years. In 1871-1872, she received further modification so she could also be utilized for gunnery instruction with a main battery of eight 9-inch Dahlgren guns, plus one 100-pound Parrott Rifle and one 11-inch Dahlgren gun.

    ----------------------------------------------------------------------

    Side note: The photo shows the USS Constellation sailing under the Francis Scott Bridge in Oct 2022. The bridge collapsed last week after being struck by a 900+ ft container ship.๐Ÿ˜”

    The Constellation folks showed me plans for a 30# Parrott pivot carriage and slide. They said that Constellation had that and a 20# pivot during the Civil War, which they said was the time frame they were working toward restoring ship.
    My model is of the ship in 1856, when she was new. They said she was armed with 10" shell-gun pivots then, and showed me plans for a 10 inch gun & pivot carriage for the Mississippi dated .
    I made that gun by hand for the model, intending to learn to photo-etch to detail it, but then I got a 3D printer and 3D modeled and printed both guns with all their details.

    The Mississippi gun is 8,600 pounds, the 10 inch Dahlgren is 12,000 pounds; but the Traversing Carriage and Slide modified for the Dahlgren is shorter, but wider, and the Dahlgren mounts lower, lowering the center of gravity. It actually fits Constellation's better fore and aft.

    Constellation was the last sailing warship the Navy built, launched in August 1854, and commissioned in July 1856. The Mississippi gun plan is dated July 1855, and Dahlgren's drawing is dated July 31 1850. Both guns are referenced as "10 inch shell-gun on pivot."
    The frigates and razzees, such as Cumberland, were all armed with 2 10 inch Dahlgren pivots on their spar decks.

    I'm still looking for data that will confirm things one way or another, or yet another, as it may turn out, but I'm acting on a hunch that she should have 10 inch Dahlgrens.

    BTW: if you notice the last image attached of the new deck tracks being worked on, you can see the back ends of the old guns slides in the image of the deck, and see the difference in the length of the old and new guns.

    Wow!!! Jerry, it looks like you came out of the wood work with this project. I'm a big fan of American Civil War naval ships and technology so I appreciate, even envy, what you are doing and have done.

    Out of curriousity, I see you have been registered here for about 7 years but have not shared that much with this
    community. I sincerely look forward to seeing more of your progress on this little seen aector of model boats.

    Now about the 10in Dahlgren and the Constellation... the pivot gun takes up a lot of deck space so I am not sure about compatibility here. I would like to see the results of your research on that.

    Your 3D resin prints look great. Lots of details.

    The next boat will be two of the same boat that hang from davits on the aft port and starboard quarters of the ship, I just call them quarter-boats.
    They're slightly longer than the 2nd cutter, but not as deep a hull.

    The pictures show the building of the 3D model. The halves of two boats in the slicer software. The models printed, but still in halves. The two quarter-boats with the 2nd cutter. The boats sitting in their relative spots on the main model.

    Got all the details into it I'm going to do, checked for "holes" and sent it to the printer, which took about 5 hours. It's 8.5 inches (216mm) long, weights about 30 grams and cost slightly over $1 USD in resin. I'll bond the two halves together and clean up the seam, then it's on to primer and paint.

    I was familiar with 3D modeling, and researched how 3D printing worked a long time ago, but is wasn't till the last couple of years that reliable-ish printers got to where I could manage to buy one.
    My modeling skill isn't so great, and I've yet to manage what it takes to reproduce the sort of carving shown in the attached picture, which is something I need to learn for both Constellation and Macedonian. Figures are also a skill I've yet to acquire, but I've never been good at drawing people.

    How I envy your ability to 3D print parts.
    So many times I could have done with this facility whilst boat building, invariably when trying to reproduce fixtures and fittings to scale.
    It can be quite frustrating to spend hours making a small item, only to find it looks clumsy or wrong in some way and it ends up in the scrap bin.
    I wish you the best with your boat build and look forward to seeing the completed job. ๐Ÿ˜‰

    I'm modeling Constellation's boats based on 1854 drawings for her boats speciffically, that I got from the National Archives.
    So far I've built the launch and 1st cutter. The launch's rail, gun mounting points, and boat howitzer are all 3D printed.

    A while ago I started a "wire-frame" 3D model of the 2nd cutter, but I couldn't get the lapstrake planking right.

    While working on a 3D models of Macedonian's stove, and a ballast bulb for Pride of Baltimore, I got an idea for doing the cutter, and though it's not as clean and fair as I'd like, it's getting there, and I've been making progress.

    At the moment, I have 3 more ribs left of 25 to put in, seat clamps, floor-boards, and some other details, before I can send it to the printer.
    The model's divided into two halves because it won't fit in the printer full size.

    There' two other boats started, the "whale-boat" or stern-boat, and a pair of quarter boats, very similar to this cutter, but slightly longer.

    I searched high and low to find left-handed taps and dies, or even steel screws and nuts to use as taps and dies to make the rigging-screws, with no luck at all. I've also bee searching for more information about the rigging-screws themselves, especially images.

    I haven't given up, but since I've had some luck with 3D printed parts, I figured I'd see if that would be up to the task.

    I just got a new 3D printer that will print larger stuff at higher resolution (more detail), and was cheaper than my original machine cost back in 2020. I think it's a little faster too. (Elegoo Mars 3)

    I made a 3D model in Anim8or; printed, adjusted the model, and printed it, a couple of times. I put a couple on the model under tension to see how they hold up, and after a few days of varying October temperatures in my unheated shop, it seems to be holding up alright.

    I saw some videos on YouTube about using 3D printed masters for "lost-resin casting" and looked around to see what it would cost to have these cast in brass/bronze from my STL file. While that would be a great solution to my durability concerns, so far it looks like it would cost over $900 USD to get 60 raw castings. That ain't happening unless this lottery ticket on my desk is a winner. ๐Ÿ˜‰

    Looking at the portrait of the ship done in 1856 by Tomaso deSimone at Naples Italy, on which I'm basing my model's appearance; I discovered, while looking for something else, that she didn't have deadeyes and lanyards on her shrouds, lower or topmast.
    I originally wrote this off as deSimone's corner-cutting, like how he leaves off ratlines on the far side of ships in his portraits. I figured the ship originally had dead-eyes and lanyards and was later fitted with rigging-screws, maybe around the Civil War. But the more I looked at deSimones other paintings, of Constellation and other ships, and photos of the ship after the Civil War, it seems Constellation had rigging-screws (turnbuckles) right up into 1910 or so.

    So, how do I make these things? The chain plates up to the screws are the same as I've been planning, but I'm going to need taps and dies between 1mm and 2mm in both right-hand and left-hand threads to make what's shown in the little sketch, and the only left-handed tools I can find on-line are from MiniTaps and are very expensive.
