I've completed modeling of the 12-Pounder gun, based on Longridge, Bugler & McKay, as well as Blomefield for barrel dimensions. All sources in this case agree very well. Here are some 3D pics. I'll attach a 1:24 scale 3-View as well, and some other scales, in PDF format. Let me know if you want anything additional. 12-Pounder Views 1-24 Final.pdf 12-Pounder Views 1-48.pdf 12-Pounder Views 1-98.pdf 12-Pounder Views 1-24.pdf

I do agree, Morgan, and that is a concern. However, a search of the Net will find dozens of carriage plans, most of which referring to the recommended plans by Robertson, and later elaborated on and copied by Hahn. Not one I have found has been specific to HMS Victory. Whereas Bugler has fairly well detailed drawings, with dimensions, and elaborate text specifying thickness of material, bolts, cheeks and more, even including what wood was used. Was he measuring the "right" or "correct" gun at the time? One would hope so, given he checked dates on cannon barrels, and seemed to know which were f

I wouldn't call this a "mocked up carriage". It is modeled after drawings made from actual HMS Victory guns and carriages on the Victory during the time of the 20s refit by people interested in preserving history and taking their work quite seriously. This study and publication by Arthur Bugler, who apprenticed on the Victory in 1918, is considered the bible as far as HMS Victory information, selling for over $500 today, and he had the full support, assistance and record of the HMS Victory Society during his work and book publication. As to the trunnion diameter, they do note 6" di

While I can't produce DXF or DWG files, I can produce PDFs. This is the project for the 32-pounder to date. I believe the barrel to be pretty accurate and the carriage as well, although I haven't yet put detail to the carriage, such as bolts, chamfers, capsquares, etc. The outline and such is about the best I can do at this point, and think it is quite accurate. I'll attach scale PDFs in a number of scales.

The free-for-hobby use version that I have does not export export dwg or dxf, or I think any 2D files. I'm not doing "blueprints" with dimensions. But I'm happy to make scale PDFs or bitmaps, and can send screen captures of my sketches showing dimensions. BTW, the statement I made that you quoted is when I was working on the Hahn/Robertson style carriage, probably most used by hobbiests, but not apparently on the Victory. I'm working on the Victory carriages now, using Bugler's drawings which mostly agree with McKay.

That sounds like a good idea. But I don't see a place for email in the profile. Unless you just type it in as a comment or something.

The carriages on the Victory are described in Arthur Bugler's HMS Victory: Building, restoration and repair, Chapter 5, Restoration details: as identical for the 32- and 24-pounders, but quite different for the 12-pounder. Both 32- and 24- are noted as having 6" trunnions, and a complete description mentions the cheeks as being 5.5" thick. Yes, I know those dimensions are different than the "standard" proposed by John Robertson in 1775 and most often used in modeling, but all dimensions and arrangement are based on actual measurement of guns from the Victory in 1922. Apparently the

For those interested in the exact profile, we have come up with the following sketch showing the side view profile of the 32- and 24-pounder brackets for HMS Victory's main guns. As mentioned above, this is based mostly on Bugler's dimensioned drawings made during refit of the Victory, confirmed with McKay's drawings, which appear almost identical, and should represent actual gun measurements of Victory weapons "at some time". I can't be specific as to era or manufacture, only that people working on Victory felt this the best representation of this gun, so that's what we're going with. Correct

Yes, I get that. Turns out (and many may already know this) but Harold M. Hahn was/is a highly skilled modeler during the sixties to near 2000. His drawing on carriage dimensions was, I am certain, based on John Robertson's 1775, London book The Description of Ship-Guns and Sea Mortars. In it is a larger table with identical dimensions to Hahn's for a carriage whose proportions were based on the caliber size of the gun. The intent was to establish standards for manufacture, although they were obviously not universally (or even often?) adopted. Some of the nicest models I've seen seem to follo

I've completed a basic 3D model of the assembly. Lots of detail to add, but this is what I've got for the basic shape and size. I'll show a couple 3D views and attach a PDF drawing which when printed full size will give views at 1/24 scale for detail. Please let me know what you think, good or bad, as to the accuracy of the drawings. New Design 1-24.pdf

Good to know. Makes sense. So, are there any other sources for accurate dimensioned or scale drawings for the main Victory guns?

This drawing shows the new bracket outline compared to the Hahn 32-pounder outline which I completed early on in this topic. The Victory design is much more compact, being lower, and sitting lower as well. The Hahn design outlined in red, the Victory in Blue:

I have completed the 2D drawing of the carriage for the Victory's 32- and 24-pounder guns. This view and dimensions will be used to extrude/produce the side brackets and the appropriate angle, with all cuts being perpendicular to the barrel, or parallel to the trunnion. The 2 sources I am using do not include the small 1/2" step down from the top before the radius to the topmost step, so I have not included it here (even though Hahn and many Victory photos show it). Here is the sketch dimensioned full size: I will be constructing the model with the side brackets being 2 piece

By the way, I have completed the carriage model posted further above, which I believe to be a quite accurate model of the Hahn carriage, including most hardware. I can post 3-views of it in any scale, or post a 3D model in the file formats shown below: While the STL file can be used to make a 3D model, I can tell you from experiences that it is too detailed with loops and such for a small scale printout, even for a quality resin 3D printer, which my son has. 1/48 scale /may/ work. 1/98 does not. 1/72, doubtful. Although it could be simplified by taking off the problem areas, like th

While I was really pleased with the carriage I posted above, based on the drawing by Harold M. Hahn, I have found no confirmation that this exact design was used on the Victory. Several designs are currently on the Victory and on land offboard, with specific information on dimensions and such. In fact, other than photographs, I only have two sources for what the 32-pounder carriages actually looked like: HMS Victory: Her Construction, Career and Restoration by Alan McGowan: Dimensioned drawings with construction details for the 24 & 32-pounder and also the 12-pounder are shown.
