If you have the ambition to build scale models of historic ships you will probably find that the classic “Pirate/Pirates of the caribean” guns is not quite flexible enough in terms of representing the difference in size of guns in use of navies and ships in general in the pre-steam era.
In this posting I will focus on the 4, 9 and 18 pdr guns. My design of these guns has some defining differences from each other. Even though there is a lot of similarities, they are all in scale 1:38 , they are all suited for ships with a mostly SNOT deck-floor and they all have the difference from the classic guns that they don’t have any working bits, but has the emphasis on looking the part. As usual I don’t claim to have come up with all the design solutions in this posting, I just think they work well and wish to share, so enjoy.
4 pdr gun
Guns of this size sometimes made up the main armament on some Galleons, like the Golden Hind. As calibers of navy armament increased up through the 17th and 18th century, the 4 pdr was used almost entirely as a chase gun. However some merchant and coastal vessels, like ships on the great lakes, still relied on this small gun.
The design is built up around the core of the gun carriage
The sides of the carriage is fairly simple, the right side is obviously mirrored on the left side.
The gun is also smooth sailing.
And with the final assembly Sir Drake is ready to blast away.
9 pdr gun
One of the largest long-guns used as chasers. This caliber of gun was also favored by some armies as a field gun. 8 or 9 pdr long-guns would sometimes be used as the main armament of smaller frigates like 6th raters or corvettes.
Once again I start with the core of the gun carriage, in this case a very simple one.
The sides of the carriage, again fairly simple, and the right side is of course mirrored on the left side.
This gun represents a greater challenge in terms of the slight bell shape of guns from this period, so the gun itself is clearly the intricate part of this design.
Now any post captain should be able to take some prizes.
18 pdr gun
This gun was used on some large frigates (5th raters) as main armament. A somewhat heavy gun while not representing emphasis on firepower in terms of weight like the immense 24 and 32 pdr guns found on the main decks of large Ships of the line.
I start with the core of the gun carriage.
The sides are slightly more complicated than on the smaller guns. However I think you can figure it out by looking at both this picture and maybe the assembly picture.
The gun itself is pretty much a more elaborate version of the 9 pdr.
And with this you are ready to dominate the high seas.
Note: The presentation shot for this posting shows long guns in the following order: 32, 24, 18, 12, 9, 6, 4 and 2 pdr caliber.
Except for the 32 pdr long gun they can all be found in my ship designs/builds.

I was curious about the measurements you used though. You say they are all 1:38th. Where did you get all the measurements for the real cannons to base the scaling off of?
Especially the length of guns vary both between nations and also between navy and field artillery, so there is not really a final answer to that question. These guns are scaled to fit in ships models in the scale 1:38 you can see the examples here http://www.mocpages.com/moc.php/298034
The scaling is mainly based on drawings, models of these ships,-the research made for the design of the LDD models.
The guns are not to be seen as stand alone MOCs but as a part for Lego ship designing that can be a real pain...
I find your designs interesting. I think it's great you've come up with something that can express the full range of available caliber options and yet retain a "style" that is recognizable for them all.

This is exactly what every avid castle / galleon building is looking for.....decent gun models !>....excellent examples, I`m sure they will be copied everywhere !>....well done
Nice work on these, I'm really glad you had the Outline Feature Turned on, it adds clarity when looking at the assembled structures. While it wasn't an issue with this set of Builds, for more complicated techniques, I suggest adding Guidelines when showing how larger portions come together to form the final product. It's simple and yet adds a lot of clarity, which reduces confusion and headaches down the linte. Again, it wasn't an issue with this series, just an idea for future consideration. Also... I posted a MOC for a contest, thought you would like to know. Also, I think you are going to be 'Jelly' when you see my images.
I have tried a lot of different approaches, including the head and wedged plates. I settled for a design targeted towards meeting the slightness of the bellshape, any kind of wedge made it way too steep for me.
I have experimented with technic, pieces, headpieces, barrels and then some. Maybe the thing that puts you off is the 1x1 bricks, I do admit that this is a compromise, as I see it guns has a pretty smooth surface, at least that is what I went for. The use of ball shaped bricks like heads makes it look too much like a line of bubbles in my view. In my own opinion the 4, 12, 18 and 24 pdr is the ones that turned out best as they have the largest percentage of round bricks in the gun barrel. However this posting is aimed at making comparable navy guns in a range of calibers that makes most vessels possible, so I included my solutions for all the guns in the most popular calibers. Btw these instructional postings are intended to be inspirational, a sort of stepping stone to my fellow moccers, so it would be ok by me if you made a posting of my gun designs with your suggested improvements.
To be honest I don't like your average gun design except for the 4 and 18 pounders. It looks too rectilineal. A common piece used in cannon designed that you have forgotten is a plain head because it gives you the possibility of a slightly superior diameter to the 1x1 round piece. Also I prefer wedge plates instead of the approach you used. Sorry if I am being offensive, you are a very skilled builder but I thought I could help you improving your gun's design. Anyway you have a couple of interesting ideas there.

Excellent guns! I dont like the samllest one too much (because of the cross-axle). Maybe flexible hose could be used¿?
Thanks, the difficulties are always in the extremes, I am also doubtful about the 32 pdr, this is why I am focusing on some of the guns in the middle range. Regarding the use of the hose, Isn’t it necessary to cut it. :(
