Progress on the 1:128 mockup from my CAD drawings. I've finished cutting out the stations and added the quarterdeck, fo'csle and poop. It's been a helpful exercise in seeing the lines of the vessel, any conflicts in terms of masts / deck cutouts / etc... Now, it's helping me think through how the stern will be constructed. I'm pleased to say that none of the frames look particularly out, except for one (frame 5) where I suspect I probably cut over the line a little... But now I can go back and take a look at this before I move onto the 1:64 scale version!

Very impressive work. Would make for a nice project in itself. 
The shape doesn't look off at all. I'll follow along.

So those numbers above have been refined again by cross referencing back and forwards from the half breadth and station plans... I got to the stage where I wanted to see how things fitted together, and particularly the deck levels and openings on the decks, and where the masts land compared to the stations, etc... 
 
So here is a 1:192 styrene half hull in construction. It's only got half its stations in so far, but it's starting to give an idea of how the whole might look.
 

 

 

Thanks Dusan,
 
I've been working on the table of offsets. 
 
1. I traced the stations, giving the following table: (note negative values are because I've maintained the right of centre and left of centre frames so I can easily do a visual check of the output with a line graph.)
 
  TRACED FROM PLAN           Distance from centre (mm, 1:1) Station WL0 WL1 WL2 WL3 WL4 WL5 U       735 1476 2268 S   303 1120 2056 3019 3825 Q   921 2068 3202 4162 4820 O   1560 2929 4102 4976 5438 M   2153 3618 4747 5490 5805 K   2775 4218 5207 5784 5972 H   3247 4617 5485 5923 6025 F   3604 4856 5635 5999 6066 D   3787 4975 5688 6014 6066 B   3908 5019 5712 6015 6066 Ø   3990 5065 5737 6015 6066 Ø (bow)   -4001 -5064 -5740 -6031 -6069 1   -3940 -5016 -5724 -6032 -6069 3   -3848 -4949 -5675 -6022 -6059 5   -3631 -4811 -5602 -5992 -6049 7   -3428 -4640 -5486 -5934 -6029 9   -3088 -4394 -5324 -5850 -5976 11   -2541 -4027 -5078 -5692 -5912 13   -2029 -3581 -4754 -5507 -5795 15   -1505 -2997 -4272 -5192 -5591 17   -1062 -2348 -3706 -4805 -5364 19   -718 -1636 -2855 -4236 -5062 21   -434 -981 -1936 -3344 -4582 23   -229 -496 -1050 -2163 -3725 25   -111 -210 -416 -879 -2079 AP          
   
The second task was to cross-check these against the half-breadth plan, which gave the following offsets:
 
  Distance from centre (updated by half-breadth) (mm, 1:1) Station WL0 WL1 WL2 WL3 WL4 WL5 U       732 1490 2343 S   267 1052 2027 2925 3830 Q   910 2025 3120 4090 4803 O   1535 2878 4001 4922 5435 M   2131 3608 4679 5446 5788 K   2694 4186 5161 5763 5975 H 93 3181 4575 5454 5922 6055 F 960 3563 4826 5620 5983 6080 D 1453 3784 4968 5696 6005 6084 B 1717 3896 5046 5731 6022 6080 (B) 1824 3938 5075 5744 6030 6076 Ø 1845 3930 5062 5741 6024 6048 Ø (bow) -1844 -3923 -5054 -5739 -6020 -6048 1 -1794 -3868 -4997 -5724 -6003 -6045 3 -1619 -3770 -4904 -5687 -5992 -6038 5 -1342 -3639 -4803 -5630 -5978 -6033 7 -854 -3411 -4641 -5526 -5931 -6024 9 -111 -3055 -4389 -5360 -5845 -5996 11   -2571 -4028 -5118 -5720 -5920 13   -2031 -3562 -4782 -5528 -5795 15   -1492 -2972 -4308 -5220 -5630 17   -1062 -2334 -3704 -4831 -5421 19   -707 -1638 -2883 -4232 -5121 21   -434 -991 -1930 -3307 -4624 23   -235 -509 -1093 -2134 -3670 25   -106 -211 -429 -885 -2042 AP

The following changes were made:
U, WL5 = 2190
S, WL4 = 3018, WL5 = 3788
 
The following image shows the original lines traced off the plans in white, and the updated lines taken from the half-breadth in green. As can be seen, the differences are fairly negligible, except at the extreme breadth, where they become a little more significant. The difference amounts to a maximum of 7.7 centimetres at 1:1 scale, so nothing too dramatic.

The next step is to begin working out framing distances, and lofting the frames using the curves these stations produce...

 
Anyway - that's enough from me for now. Happy building, all.

I couldn't resist seeing the model so far jump off the drawing board into real life, so I've started to make a basic paper half-hull mockup at 1:96 scale to get a sense of the lines. At the moment there's no lateral support for the frames, so they're all over the place, but an interesting exercise nonetheless, and adding the poop / quarterdeck / upper gun deck will help matters no end. The deck locations are marked with solid lines and waterlines are marked with dashed lines. This half-hull should help me work out how to go about realising the internal structure.
 
Progress so far... 
 

Thank you Druxey. I'm using QCAD Pro (https://qcad.org) - I used a mac and linux for a good while, and this program is robust and works beautifully on each, but also on Windows which I used now. It has a free version which did the vast majority of what I wanted, but I was so pleased with it, I thought it worth supporting the developers. It can generate dxf files which import into blender, so there's no great problem if you want to take the work and use it for 3D work, too.

So those numbers above have been refined again by cross referencing back and forwards from the half breadth and station plans... I got to the stage where I wanted to see how things fitted together, and particularly the deck levels and openings on the decks, and where the masts land compared to the stations, etc... 
 
So here is a 1:192 styrene half hull in construction. It's only got half its stations in so far, but it's starting to give an idea of how the whole might look.

First I would like to thank everyone for all the likes.
 
The gun ports were cut and lined as per an option in the instructions.  The porthole locations were laid out using the templates provided and the brass rings were attached to the hull using some ac glue.

 
The same brass ring used for the portholes was supposed to be used for the hawse holes just flattened out into an oval shape.  After doing this I just didn’t think the ring was the appropriate size.  I used some brass wire to form an oval for the outer hawse hole and went a little farther and cut and filed a piece of brass tubing to line the hole through the hull.

 
The brass tube was eventually filed down flush with the inner bulwark.

 
Since the hull will be painted I just used some wood filler to fill the gaps around the wire and tubing.

Gun Port Patterns – Installation
Following on from my last post where I detailed the preparation work with regards to the upper and lower gun port longitudinal frame patterns I have now glued patterns in place.
 
I brushed glue in both the pattern and bulkhead slots. After each pattern had been glued in place a wetted paint brush was used to remove the excess glue, with some of the excess diluted glue being brushed into the joints.
 
The pencil lines do match up so I know the patterns are fully engaged in the bulkhead slots.

 
The patterns, when glued, stayed in place without the need to use clamps for the most part. There were a couple of bulkheads where it was necessary to hold them in place.

 
Before removing the vertical gun port patterns from the MDF sheet, I did add a part reference in pencil.

 
I then dry fitted all these vertical gun port patterns all to make sure there was no installation issues. Next each vertical gun port pattern was removed in turn and the pencil marks were removed with an eraser. Glue was added to both the pattern and bulkhead slots and the pattern was then refitted. The excess glue brushed away with a wetted paint brush, with some of the excess diluted glue being brushed into the joints. It did not take too long to glue all the patterns in place.

 
Next task should be the fitting of the gun deck sections and stern counter frame patterns. I will have limited time in the shipyard over the next few days due to grandparent duties so not sure when this will be done.

So those numbers above have been refined again by cross referencing back and forwards from the half breadth and station plans... I got to the stage where I wanted to see how things fitted together, and particularly the deck levels and openings on the decks, and where the masts land compared to the stations, etc...

The following image shows the original lines traced off the plans in white, and the updated lines taken from the half-breadth in green.

The difference amounts to a maximum of 7.7 centimetres at 1:1 scale, so nothing too dramatic.
