excellent boats!!! and excellent guns !!

its a great looking model getting better with each addition

While checking images for other pin-rails, I found a little detail in one photo that I verified in others; the mizzen pin-rails also had a mallet-like pin in it, probably for the mizzen tops'l yard. It also had more pin, closer together than I initially modeled.
[attachment=1]tenderizer.jpg[/attachment]
So I fixed the model and printed a new pair:
[attachment=0]con20241213a.jpg[/attachment]

Besides working on other model besides [b]Constellation[/b], like my [b]Pride of Baltimore[/b], I went and had a stroke back near the end of June. Basically the summer was shot, as far as getting any work done. I am getting detailed things back, like handwriting, but it's gotten cold, and there's no heat in my shop/garage, so getting physical work done is still stalled. My goals for the spring are getting [b]Pride[/b] sailing, if not finished; and beginning proper rigging of [b]Constellation[/b].

To that end, an item [b]Constellation[/b] needs before rigging can begin are her pin-rails. It'll be near impossible to install them once the rigging's going up, and many rigging items attach to the pin-rails.

I opted to 3D print the pin-rails that attach to the bulwarks as I did the ones at the base of the masts.
[attachment=8]con20220620d.jpg[/attachment]

There are basically four pairs of pin-rails: Port and starboard at the mizzen, main, fore, and a pair at the bow on either side of the bowsprit.

Building from the 3D models of the mast rails, mostly belaying pins and the shape of the rail, and getting size and shape from an 1888 spar-deck plan, and the few photos that show enough of anything to work with; I started with the aft rails. The printed with a little deformity at one end that was repairable, but I also had forgotten to account for the fact that the bulwark they attach to leaned inboard and I had not modeled in that angle. I fixed the 3D model and it printed perfectly.

[attachment=5]con20241209b.jpg[/attachment]
The mid-ships and forward rails had what I thought were [i]cavals[/i] but in better photos turned out to be big clunking square belaying pins like carpenter's mallets. ([i]note: I just discovered the aft pin-rails had one of these as well, so I have to fix that model again[/i])
These were also too long to print as a single piece, so I modeled them in two halves to be bonded together after printing.

[attachment=3]con20241210b.jpg[/attachment]
Next came the bow pin-rails which I appear in many photos, the best being from 1926;
[attachment=0]bow.jpg[/attachment]
The bulwark here leans outboard so the back angle of the rail needed to be reversed
[attachment=2]con20241211a.jpg[/attachment]
[attachment=1]con20241211c.jpg[/attachment]
There's a fife-rail around the base of the mizzen (rear-most) mast, but I can find any thing showing pin-rails at the stern. There may be pin-rails in the mast tops, or just cleats seized to the shrouds. to determine this will require investigating the ship's contemporaries as I haven't found anything specific to [b]Constellation[/b] regarding it.
These rails need to be drilled for attachment pins; then primed, painted, and clear-coated before they can be installed.

After airbrushing on a couple of coats of Testor's Flat Olive, I painted all the hardware with Testor's Flat Steel, then cut in the Olive again to neaten things up. The rollers were lignum vitae, a very hard wood used for such things, including sheaves in blocks, and bushing blocks, and so on. These I painted "Rust."
[attachment=1]con20240417a.jpg[/attachment]

The aft gun (left in photo) lost a roller during printing and I replaced it with a bit of mahogany dowel, and filled in the missing portions with built up resin ~ drip some in, zap with UV, drip in some more, zap again, etc. There's a little more touch-up painting, and then clear-coat to do.
[attachment=0]con20240419a.jpg[/attachment]

These will get attached to the access hatches as shown, with two screws each. Eye-bolts will get installed along with the blocks and tackle used to shift the guns about on deck. The aft gun is set off like that and will have a few crew members around it to be more interesting, and out of the way of the spanker sheet - this [i]is[/i] a working model after all. The forward gun is left centered and no figures will be up here to keep clear of the heads'l sheets.

John Dahlgren submitted a drawing, dated July 31 1850, proposing his idea of the ideal armament for "First-Class Frigates" suggesting they be armed with [u]six[/u] 10 inch pivot guns on the spar deck, and 26 9 inch guns on the gun deck. The Navy rejected the proposal, mostly; they opted for two 10 inch pivots and the gun deck armed with 8 inch shell-guns and 32# shot guns, and the big frigates, razees (cut down frigates) were armed in this manner, including [b]Constellation[/b], the newest, and largest sloop-of-war that wasn't a razeed frigate.
[attachment=7]x_inch_dahlgren_pivot.png[/attachment]

On a visit to the ship, years ago, they showed the [b]Mississippi[/b] Pivot Gun plans, saying that was what [b]Constellation[/b] was originally armed with; which were eventually replaced with Parrott rifle pivots, a plan they also showed me. I took some pictures of the Parrott plans, but went to the National Archives in College Park Maryland, to get a proper copy of the [b]Mississippi[/b] plan.
On August 26 1854, the sloop-of-war [b]Constellation[/b] would be launched. Almost a year later, June 1855, the plan for the 10 inch pivot guns for the side-wheel frigate [b]Mississippi[/b] was drawn. Another year on, [b]Constellation[/b] was commissioned on July 28 1855.
[attachment=8]10inchpivot.jpg[/attachment]

It seemed to me to be unlikely the ship would be armed with a gun from a plan drawn a year after her launch, while her razeed contemporaries were armed with the Dahlgren around the same time, 1853~1856. So far, I haven't been able to track down any sort of documentation that can nail down precisely which 10 inch shell gun [b]Constellation[/b] got. The [b]Mississippi[/b] gun is, so far as I've seen, always referred to as a "10 inch shell-gun of 86cwt" while the Dahlgren simply referred to as a "10 shell-gun" or a "X inch shell-gun." I haven't yet found a references to [b]Constellation's[/b] guns as "86cwt." The 10 inch Dahlgren is 120cwt, and I've never seen anything referring to it in that way.

Since it's really isn't that big a job, being able to 3D print now; I decided to switch the model's pivot guns to Dahlgrens. Since I was already making the 3D model for my Naval Gun project, it didn't really add to the work-load.
[attachment=6]x_dahlgren_pivot.png[/attachment]

The slide for this gun, while very like the [b]Mississippi[/b] gun's slide, was wider and shorter. I used the slide from the 3D model of the previous pivot gun, shortened and widened, which saved some time and effort.
I printed the gun in three parts; slide, carriage, and tube; to facilitate painting, and reducing what I'd need to reprint if one of the parts failed. The first gun lost one of it's rollers, but I could fix that without reprinting. The second gun printed perfectly.
[attachment=5]con20240331a.jpg[/attachment] [attachment=4]con20240331d.jpg[/attachment]

A shorter slide meant I needed to make new deck tracks, which I 3D modeled like last time, but I made them short/thinner to be more in scale.
[attachment=3]new_tracks.png[/attachment]

The guns are mounted on access hatches, fore and aft. I removed the old tracks, sanded the scars best I could, and re-coated the hatch decking with polyurethane. The newly printed tracks were primed, painted, glued onto the hatches, painted again, and the whole thing was clear-coated. The guns too were primed, and the tubes painted and detailed, but the carriages and slides are waiting to be painted the same olive color as the old set.

I started on the 3D model of the whale-boat before the quarter boats were done, and it was complete and printed overnight on the 7th. That's the last boat for [b]Constellation[/b].
Since then, it's been filling, filing, sanding, and repeat, to make the seams on all the boats go away before I prime and paint them.

I realize these model's are "low-poly" but they fit in with the level of detail of the over-all model, and it's not like I'm trying to sell them. I was going to post them on Thingiverse, but most folks that would want them would want to scale them down to a more common modeling scale; like 1:85 which is what that abomination Artesania Latina pukes out claims to be. Anyway, scaled down, I doubt these models could survive the print process, so I'm not going to inflict them on anybody.

[size=150]Once the 2nd cutter was printed, I focused more on the quarter boats. It's one 3D model, but two of them get printed to eventually hang on davits on the aft quarters of the ship.
[attachment=5]quarterboat20231230c.png[/attachment] [attachment=4]quarterboat20231230d.png[/attachment]

These boats look very much like the cutters, but are a little longer, not as tall, with narrower sterns. At 1:36 scale, they're about 8-7/8th inches long (22.5cm). All the boats will be too long to print in one piece, and are made in halves, but both quarter-boats can be printed at once with room to spare.
[attachment=3]quarterboat3d20240101a.png[/attachment]

Printing took about 5-1/2 hours.
[attachment=2]con20240102c.jpg[/attachment] [attachment=1]con20240102f.jpg[/attachment]

Here's the boats sitting about where they'll live on the main model
[attachment=0]con20240102g.jpg[/attachment][/size]

[size=150]As 3D printing things for the models was going pretty well, I decided to also print the remaining boats. I had already built the launch and 1st cutter, and planned to build the 2nd cutter next, in the same way, but began a 3D model back in 2020.
[attachment=9]con20231022ea.png[/attachment] [attachment=8]2nd_cutter20200803a.jpg[/attachment]

Only the launch is "carvel planked" while all the rest are "clinker" or "lap-strake" with over lapping planks like house siding. That's much more tedious in 3D modeling than a smooth-hulled boat. Eventually I got something I could live with.
[attachment=7]second_cutter3d20231127b.png[/attachment]

Then adding details, adjusting what seemed like everything all the time, and every one of 25 ribs.
[attachment=6]second_cutter3d20231203.png[/attachment] [attachment=5]second_cutter3d20231217b.png[/attachment]

Finally it was ready to be printed
[attachment=4]second_cutter3d20231219.png[/attachment]

It was made in two parts so it would fit in the printer, and the parts had to be arranged and written to the STL file, for slicing.
The slicing software said it would weight 29.9 grams (1.6 ounces), use $1.05 worth of resin, and take 4h 50m 57s to print.
[attachment=3]second_cutter3d20231216a.png[/attachment]

To the printer it went...
[attachment=2]con20231219a.jpg[/attachment] [attachment=1]con20231219b.jpg[/attachment]

After bonding the two parts together, the seam will need some clean up with files and sanding, then it'll get primed, painted, and a UV resistant clear coat. Then it'll be placed on the 1st cutter, after I make some boat chocks.
[attachment=0]con20231219g.jpg[/attachment]

Over-all, the whole thing leans toward being too thin, but it's usable for me. I was going to share the STL on Thingiverse, but most folks that downloaded it would probably want to scale it down to one of the more common kit scales , and most of the surfaces would become membranes if not disappear entirely.

This expectation and experience is going into the 3D models of the remaining boats. Beside being able to scale them down, they need to be thicker/stronger, because they'll hang from davits out-board, which gives them a higher chance of being damaged in handling and operation.[/size]

very very good indeed--the 3-D prints really enhance the look

I was most impressed with the beautiful tracks... :thumbs_up_1: :thumbs_up_1:

A bit of research nailed down that the ship was rigged with rigging-screws (turnbubkles) from the start (1855), and didn't get deadeyes-and-lanyards until nearly 1914.
[i]The red arrows are the rubbing boards I was looking for when I realized this 1856 portrait of the ship showed she didn't have deadeyes-and-lanyards.[/i]
[attachment=3]rubrails.png[/attachment]

Finding good images or specs on these things is hard, but going with the best photo I could find, I came up with...
[attachment=2]turnbuckles.png[/attachment]

Obviously, you won't find these things, especially in 1:36 scale, at any vendor, and I couldn't even find left-handed taps and dies (or steel screws and nuts to use as taps and dies) to make a functional version with. Having had good luck with 3D printed parts in a somewhat "structural" use, I opted to model and print them. I saw 3D printing used to cast jewelry, and looked into that with the idea of having solid, non-functional ones in brass, but that's not looking like something I can afford to do, or have done.

[attachment=1]con20231018b.jpg[/attachment]

After adjusting the 3D model, 45 more were printed...

Jawdroppingly awesome. Wow ...

Shifted work to another model trying to get it's controls in order. But [b]Constellation[/b] did get some work done...

Thank you gents, for your kind words.

I always intended to make the hammocks exposed as that's how the ship appears in every painting and most photos.
[attachment=0]Constellations.jpg[/attachment]

The 1856 painting of the ship at Naples is the one I'm basing the model on.
I was considering making some hammocks in Skulpty, making a rubber mold from that, and casting them in resin. 3D printing not only gets the end result, but I 3D modeled them hollow to save resin, make them cure better, make them lighter, and the whole thing is cheaper in terms of resin and effort, plus I can easily alter the file if need be.
Here's all 200 hammocks mostly in groups of 9.
[attachment=9]hammocks2.png[/attachment] [attachment=3]con20220420a.jpg[/attachment] [attachment=2]con20220424b.jpg[/attachment]

Some of the bullseyes printed before got attached to the bobstays, and put back on the boat with temporary lanyards.
[attachment=8]con20220414a.jpg[/attachment]

I altered the oar model a little and took a shot at printing 45 at once. I didn't leave enough space between them and the supports got fused to the oars in a few places. It's been difficult to dig them out, but I'm managed 27 usable ones so far.
[attachment=7]con20220417a.jpg[/attachment]

I printed a new wheel to replace the too-fragile one I bought, but I liked the wooded pedestal I made for the old one better. So I sawed off the resin pedestals. Now the wheel will spin again, so I'm reverting back to plan A and connecting the ropes to the rudder servo so the wheel will spin when the rudder moves.
[attachment=6]con20220419c.jpg[/attachment]

The new skylight sashes and the wheel all got painted. The skylight sashes are glazed with a couple of microscope slides.
[attachment=5]con20220420f.jpg[/attachment] [attachment=4]con20220419g.jpg[/attachment]

The gun circles (rails on the deck for the pivot guns to slide on) were hand cut from sheet styrene and were too sloppy, too wide, and too thin. I modeled new ones using the 3D model of the gun as a reference for size and proportion. These got printed in one go, but unlike the oars, I left more space between things so the supports would stick to the parts.
[attachment=1]con20220422a.jpg[/attachment]

I just replaced the LCD screen on the printed a week or two ago when it went bad. After that I found there was an upgrade for my printer available that would reduce print time by as much as half, so I ordered that. While printing trays of hammocks two at a time (all that will fit on the plate) the vat got a small leak and stuck to the LCD. Before I realized what was happening, I'd torn off the ribbon connector. The upgrade screen hasn't come in yet, so no printing's been happening for a few days.

In the meantime I've been working on the 3D model of the 2nd cutter (which stacks on the 1st cutter on the main hatch). If I can get that to work, I can alter the file to also make the two quarter-boats (same boat but a little smaller) and the double-ended stern boat (whale boat).

Great build and beautiful example of perseverance! :thumbs_up_1: :thumbs_up_1:

:woo_hoo: :thumbs_up_1:

most impressive home printing!!!

ship looks very good !

JB

Printed more crew figures, basically the ones that didn't get printed, or didn't print correctly with the first batch. With Ivan and his comrade from the Soviet Naval Troops kit, this makes 19 and a cat, out of the 40ish I intend to have.

The skylight got new panels with more detail and better sized.

I modeled and printed the Night Lifebuoys to hang on the stern. I got drawing of the ship back in 1999, showing the ship in dry dock in 1859 that showed these things, but I had no idea what the drawing was intending to show (I doubt the artist knew what they were either). I finally figured out what they were and made the best models I could with the details I had.

I modeled some studded chain for the anchors and got them to print without bonding the links together. All four chains, and a shackle to attach them to their anchors are printed and painted.
