After completing the gun for l'Orenoque, I went back to complete the taller carriage based on LaFay's plate #7 Attachment:

Canon Oobusier 22cm No1 |

Someone building a 1:100 model of the French steam-frigate L'Orenoque was looking for guns to replace the kit's white-metal "things." Technically, this gun was produced in 1842 and falls out of the range of this thread, but it was in-use through the 1850's, so I'm posting it here.
The tube was easy enough as I found scale drawings of it that all agreed, and I used what was in the book Arming the Fleet since I have it to scan. The carriage I originally started making was based on a portion of the model's plans I was sent.

I didn't care for the carriage, it was too tall, so I scaled it down to match my 32# and 8 inch shell-guns carriages, and it still felt wrong.

I was happy with the carriage, but LaFay didn't show how elevation was handled. The model plan had a coin on a block, also not shown in the LaFay drawing of that carriage (plate 7). LaFay did have a drawing of a coin, separate from any gun plate, so I put that on a block as in the model drawing.

I loaded the gun into the slicer and scaled it from 1:36 to 1:100 and printed 7 of them. It took three tries, but using fatter supports on the last try did the trick.

I did something like this in 2D for my laser-cutter and then build the sculpting with white glue and acrylic paint.
You could do it also in 2D as thinnish element for the printer and then build up the volume in the 'traditional' way - that is, if you want to duck the challenge with Blender.

If you're doing a ship with some 28ish IX inch Dahlgrens on Marsilly carriages; that would be a project all by itself. I just wish I could wrap my brain around Blender so I could model the filigree carvings on the ship's bow. I have an eye for that stuff, good enough to see how awful my hand is at it. Attachment:

Having built something like that from scratch using traditional methods (if photoetching and laser-cutting can be already considered 'traditional'), this 3D-printed example seems to provide a considerable gain in time (and perhaps quality), particularly when one needs more than one specimen.

Nope. They added a caster sort of thing to train the gun, and a different style of elevation mechanism. I think there may have been a wooden bolster, or bumper, forward for when the gun was run up, but the only evidence I have for that is a rotting bit of wood on the front of one of these sitting in a park. These are definitely NOT "display carriages." BTW: If you look closely at photos of extant carriages, those skids appear to be bronze. as do the trunnion fittings. Attachment:

Shouldn't there be a wooden (sacrificial) bolster under the rear end? All French carriages from that time I have seen seem to have it and it looks logical, as you don't want to have the angle-irons scraping along the deck.
Somehow, however, this looks to me more like a modern display carriage. Just two sheets of iron don't seem to be stiff enough to take the force of recoil. Normally there would have been an iron frame that is covered on both sides with sheet-iron for cross-stiffening. At least that was the way French and German gun-carriages of the time were constructed.

It's looking like I'll need to do the rest of Warrior's armament, I guess ...but I'm not building a model of the ship, no sir.

Thanks for the video. I didn't know that one. And, I didn't realise that the ball-lever is not connected to the breech-screw, but can rotate separately to tighten it with its inertia.

Armstrong 110# 7in BLR of 82 cwt |
 |
|
A discussion on 3D modeling guns on another forum ;ed to a data exchange with a fellow in Italy named Carlo, that likes to model cannon in CAD. He passed me some data not only on the 110# Armstrong, but several other Armstrong guns. I passed him some data he lacked, like how the parts of the breech-screw went together.
This got me interested in revisiting my 110# BLR and making the breech functional. Initially I was just going to make the breech-screw (BS) shallow threaded and the breech smoth, so the BS would friction-fit, and printing in smaller scales wouldn't be an issue. But Carlo sent me an STL of the breech with it's threaded insides, and the breech-screw with matching threads. I just had to see if this would work, so I scaled this to 1:36 and printed just this bit to test it. The scale threads were much too fine to work without some hand-work with a file, and if scaled wouldn't work at all. Instead of giving up, I made coarser threads. I couldn't use Carlos' breech, so I made a new breech from scratch with my coarser threads in it.

A YouTube video of a 110# Armstrong being loaded and fired at Fort Nelson in Britain shows how the "lever" spins on the breech-screw to work as a hammer to tighten or loosen the breech-scew.
I recommend right-clicking and opening the video in a "new tab" https://youtu.be/LqUkDQ3BQ1A?si=-ATPpYwuslyXLWXe
I separated the "lever" from the BS, and modeled a groove in the back-end of the BS to accept the "keeper-pins that would hold the lever on the BS. It's all a bit awkward to describe, but hopefully pictures will help:

The holes for the keeper-pins needed to be drilled out after printing, and I need to fine some wire for the pins, but it should be functional, allowing the lever to spin as in the video. The coarser threds on the breech work great without any hand-work, and should scale down to 1:96 and still work. The lever's function, on the other hand, I don't think will scale small at all, so I made a BS with the lever attached and not spin that will scale just fine.
Then I printed the carriage and slide for the first time

It didn't print great, a gremlin got into the print and started chewing on a corner of the slide as it was finishing.
I'm pretty much finished with this gun. My brain and wrist need a rest from all the mouse-work in my modeling software. All the STLs have been posted to Thingiverse for anyone to take a shot at
