Well done!!  Your work is so crisp and precise.  An inspiration to us all.

 

Regarding the last photo...I'm sure it was nice to not have to go to the "head" of the ship!  Especially in heavy seas.

I haven't posted here for quite some time, but nor have I progressed much. 

A friend of mine created the guns in 3d and I got them printed in resin, however I wasn't at all happy with the result so I got them printed in plastic instead. These turned out a lot better, but I'm not sure I'll use them. I'm considering turning them in bronze instead, though I've never tried turning metal. 


I'm now proceeding with the quarterdeck, I need this done before I can finish the rudder tiller and its rigging. 
Strangely there's a missing beam where the mizzen mast sits, I would have thought that area needed more reinforcement, although at least those beams will be supported by horizontal knees.

I have an issue regarding the beams around the mizzen mast on the quarterdeck. According to the plans there's a beam missing here, with horizontal knees to add strength around the nearby beams. However the way the supports for the mizzen are shown on the plans frankly makes no sense to me. They are shown as resting on only one beam and the other side is basically floating free. 
Here I've colored the beams in green, the red planks are the support for the mast, which as can be seen do not reach all the way to the next beam after the wheel. The 3 azure parts are the ledges, and the yellow the middle carlings on which the ledges rest. The above quick sketch is my interpretation of the plans and the next sketch is how I believe it should be, by extending the mizzen supports all the way to the next beam, which if course would add weight on the real ship. 
I just don't understand why there's a beam missing here; maybe to allow for the rake of the mizzen to be adjusted? As it is now, there's definitely room for another beam though of course I'd have to remove the horizontal knees (I haven't added them yet).  I wonder if anyone can enlighten me, if you know of any other ship constructed like this. I've looked through contemporary plans of other Spanish frigates but they don't show the beam layout for the quarterdeck. 

Edit: I forgot to add - the missing beam is right above the gun port, which would make it very difficult for it to have knees underneath it. Maybe that's why it's missing?

I've been looking at contemporary plans of Spanish (and other nations') frigates and ships of the line, and either they don't show the quarterdeck beams or there are none missing. I also can't see any reason whatsoever for the missing beam behind the mizzen, so I went ahead and prepared one. It's not glued in yet so I can still change my mind, but I think it's the most logical way to construct the ship. I can only imagine the mizzen would require some support since it's stepped so high above the keel, and a beam is the only way I can see to provide that. 

There's also still enough room to change the angle of the mast if that's something they did back then. 

Of course due to the gun port there's no room for a vertical knee, but I'll install a horizontal one instead which again would make sense to distribute the forces from the mast to the frames. 

Also, I'm probably overthinking this way too much! 😂

Makes perfect sense!  Looks correct too.

 

Nice work, thanks for sharing!

Although I wanted to reply to your original post regarding the beams I didn't due to my lack of expertise.  However I did think exactly the same as you for the solution as it makes perfect sense as BradNSW has already mentioned - lovely work!

A hanging knee over a gun port (at least in English practice) would be 'cast' or angled around the port. Her there is insufficient space for this solution, so omitting it entirely is reasonable.

That's a good point, thanks! Some of the other beams amidships have angled knees, but this beam sits right on the top of the gun port so I don't think that's a solution, as you point out. 

Wouldn't a horizontal knee help support the forces from the mizzen mast though?

[druxey]

Horizontal lodging knees would be vital, I would think! The other, less likely, possibility would be beam arms.
