@TJM I see there are two versions of QCAD available. Are you using the regular QCAD Professional or is the QCAD/CAM version?

The regular pro version. I think I paid $40 or something like that.

Ørnen, Royal Yacht of Christian VII

 

I have been away from home and with no workshop, and have therefore been adapting some more historical plans. 

 

This time I am looking at a small Royal Yacht called 'Ørnen' (the Eagle). 

 

It is a curious little vessel entirely geared towards ensuring the comfort of the monarch. It is basically a large suite with two bedrooms (labelled king's and queen's, respectively) and a living room. Midships there is a finely decorated dining hall and at the bow a kitchen with two stoves. 

 

Armament consists og 26 4 pound 'houbitzers' that seems to be essentially small swivel mounted carronades. Good for defence! 

 

Here are a few of the many original drawings:

 

 

 

 

 

 

The dining hall is an interesting feature to model, and in general it would be fun to model the interior of the ship to a reasonably high level. 

 

Here are the lase cut sheets I made:

 

Mostly 3 mm MDF and then a little 2 mm and 1 mm ply. Most of these thinner pieces I would do in pear if I was to continue with this model (I would like to, but that will be in the distant future, if ever...), but the ply is fine for checking if it works.

 

And here are a some photos of the puzzle fitted together (very little glue for now, just at the stern and bow):

 

 

 

 

 

 

 

 

And a few with the test cardboard bulwark patterns:

 

 

It is a small ship, 45 cm at 1:64. 

 

Here it is on top of Bornholm from the last post:

 

 

I am a bit torn on whether I like the ship due to it's curiosities or if I think it is a little ugly with that dining room protruding in the middle. But it has nice enough hull lines, and is a bit of an unicum.

 

But now that I am back home, having spent an evening cutting this, I will get back to planking of Christiania 😁.

That is a lovely and unusual subject! I vote you continue.

Thank you Druxey, I will definitely consider it. But I am not allowing myself more than one truly active build at any one time, or I would never finish any! So It will be a long while no matter what before I continue, with this, Bornholm, Fehmern or another of these practice projects.

Thank you very much for showing us this lovely yacht! As I have mused through the plans there are some interesting details on it, for instance the deck which curves down to the stem to allow for the cables of the anchor to come up smoothly. A little yacht worth of being considered for a nice model, which at 1:64 would be of just the right size. I also completely agree with you that dividing modeller's attention to several subjects at the same time is a good way to never finish anything. However, I know modellers which work just like that, taking small steps to several models in the same time. Also unlike the girlfriend, a ship model is never jealous of being left some time on the shelf for another ship model! 😉 

Also you did a very nice job in cutting these pieces and putting them together. It seems it takes much less time to project the cut on a computer and then laser it all in a single pass than it would have to cut them by handsaw and then smooth them one by one! Nice one!

 Thank you for the very nice comment! Indeed, many fun features, I had also noticed the dropping deck. 

 

Indeed, it does not take too long to do this, at least not the small ships like this one and only the base structure. I think this one took around 10 hours to do in CAD, another couple to lay it out for cutting and one to cut it on the laser. I am sure it would have taken ne forever by hand and scroll saw!

I'd say by all means open a log in the scratch area when you're ready.
