Sometimes the ship is commissioned into the cruising fleet 'as is' after repair if needed - HMS surprise (ex L'Unite corvette) was still armed with her French 8 Livre and 4 Livre guns when she sailed to Jamaica in 1796. On arrival at Plymouth in 1798 she was remasted, her spardeck bulwarks were built up, French guns removed and the plan was for British equivalents to replace them (9 pdr, 4 pdr guns 12 pdr carronades... but the Admiralty was persuaded to replace them with a carronade heavy armament of 32pdr and 18pdr carronades (and either a 4pdr or 6pdr chase gun pair). Things could be similar for the French too.. 2 of the French fleet at Trafalgar were previously British ships and still carried their British guns. For rigging, even if the sticks are the original foreign materials, the rigging might be adapted towards normal national practice, during repairs or while otherwise idle.

The Manger is usually described as right forward under the fo'c'sle. Which seems to fit with the location shown.
-
Is that not the manger? On the upper deck, rather than the RN frigate's 'gundeck' which is the unarmed one below.
-
Are you sure they aren't removable, rather than hinged lids? This type could be rigged when the guns were stowed alongside the bulkhead (or have muzzle cutouts and a split cover design if the guns were stowed run-out) and usefully increase freeboard, but were stored below when cleared for action. This is also a common variant for 'open' waist ports on frigates or ships of the line where they aren't fitted with hinged ports.

I think it is an excellent idea. That was the reason I assumed for a 'throw-away' build... make sure that both options are buildable and correct/refine any problems as you make one quick'n'clean build.
-
Am I seeing a Hermaphrodite build? Carronades to larboard and guns to starboard?

Scout was a 1915 predecessor to the 1916 Pup. They aren't the same airframes, and the most closely related was the 1 1/2 Strutter (of which the Pup was the diminutive offspring - to the annoyance of the Admiralty) Pup is 8.3m span, Scout was 7.49m, length Pup 5.89m, Scout 6.3m. Scout uses the 80 Hp Gnome monosoupape, while the Pup often uses the Le Rhone 9C 80Hp as one of it's engine options.

The contemporary definition for these things is instructive. Thickstuff comes from the full depth of the tree, and is sawn to thicknesses of 4.5-12" Width is cut to suit when used. Plank is over 11" wide, and over 1.5" thick (but less than 4") Deal is around 9" wide and 1.5-4" thick Batten is 6-7" wide, 2.5" or under. Board is under 1.5" Deal lengths are typically 12ft, but these dimensions can all vary with the source of the material. (Ends are short lengths under 8', rather than the full length of a standard load.) A load is 50cu ft of finished timber, 40cu ft of rough timber. When worked the finished weight of a hull is about half of the timber used in her construction. Roughly. Finished loaded displacements hover near the rough weight of the timber expended in their construction (depending on hull form being comparable to a full bodied frigate or ship of the line.) - a mix of masting, rigging, anchors, guns and ordnance stores, crew and stores, and whatever cargo/passengers are substituted for some of that.

3D Naval Guns 1850s ~ 1870s
Lieste replied to JerryTodd's topic in CAD and 3D Modelling/Drafting Plans with Software
The 'taller' block trail carriage is dimensioned as 989mm to the top of cheeks (526+323+140), while the 'longer, sleeker' one is a little over 940mm (890 +50 for the rise of the lower edge ahead of the truck - it is 450mm above the breast). Both are for 22cm no1 guns of 1842, 1841 and for different vessels. I believe the taller carriage may be the standard 'tween decks' (lower battery) carriage, while the (very slightly) longer and lower one is intended for the spar deck of paddle steamers. As the model is a paddle steamer, this is likely to be the proper design, if not on a double pivot. -

In particular - the anspect (levers) for this carriage type have a little roller allowing them to form a 'rear wheel' for when running the guns in or out. Those for truck carriages for earlier patterns of guns just bear the rounded end on the deck to shift the carriage about. -

The PDF is a lower res than the online 'zoom-view' where you can easily read dimensioning etc. I have offline copies, but will go onto BNF to get a better view of plates (and some tables). They have a variety of other texts as well, but Lafay is one of the more and better illustrated. The online browsing can sometimes be a bit glitchy though. Being able to zoom at higher resolution is useful for an inset part of a larger plate, which can otherwise be obscure. There is a plethora of French pattern instruments and gunner's materials in the plates too. Not sure how early these patterns would extend, as Lafay is c. 1848 with some last minute additions. Most should go back to the 1837 regulations (unless specifically dated after that) -

That one is in Lafay too - a few plates after the 'taller' 1840 no1 carriage. Plt 17 lower -

Douglas 1855 has some drawings of a pivot and a (very flat) block trail carriage for the 1842 no1. In line at art 221 Also, try Lafay at BNF https://gallica.bnf.fr/ark:/12148/bpt6k9737980n/f789.item.r=lafay artillerie Several different block trail carriages and also pivots for the obusiers. (Also the later mod of the truck carriages, braque fixee for the caronade, embarkations etc) In the end plates. -

They are parallel to the sheer of the deck to allow the gun to train without restricting depression or elevation at the extremes. The sides are parallel to the frames, which may not be perpendicular to the waterline. This results in each port having a different (non-rectangular) shape in practice, this is fairly minor except right forward and aft, but there is a reason each gun, carriage and port-cover was specific to a particular port.

The double thimble sounds like a modification to the seized breeching at the breeching rings paased through the side. Each end of the breeching, seized to a 'thimble and hook' in the bight, can then be detached at will, rather than being reeved through the breeching loop after the seizing is unpicked. The gun and carriage can then be shifted without removing the breeching from it. (looking at the definition of a 'Gripe' and extending it to a 'double thimble', rather than dead-eye and thimble) The earlier Contsplice could of course be pulled from the gun when needed, allowit it to be shifted, but the breeching, seized to the side would need to be shifted also, or substituted in the new place. A slightly later modification to the breeching loop allows it to be interrupted with a shackle to close the gap to restrain the breeching. If this is correct, then the contsplice is still needed for non-looped ordnance, with the double thimble being a convenience for looped guns which don't have a shackle opening, and more generally for ease of shifting or striking/removal of guns.
