D805 Piet Hein, ex HMS Serapis, WW2 S class destroyer

[Marquinius]

So, I finally got back to D805 Piet Hein. I had losts of other fun things on my mind, but now that the temperature has gone down a bit, I can survive in my work shed.

Where I'm at, just to recap: most of the upper structure has been printed and primed, but not glued in place. This means that also some of the more detailed parts are also well underway, e.g. the torpedo tubes, and now the depth charge towers. I started with creating a depth charge to scale and used that as a measuring "stick" to create the racks. And I did a similar thing with the throwers. I still need to do the rear rack / roll off mechanism.

Most of the design work was done at 100% and then scaled to 72. This meant that I had to exaggerate some details, as they otherwise would simply disappear during the print phase. As an example; an air/hydraulic tube may be 3/4 inch in real life, but would be 0.02mm at scale ... so invisible. The racks are 18mm tall. The torpedo tubes are about 90mm long. From a flat not really understandable drawing to Fusion to print. Not too bad!

I am impressed Marco, those torpedo tubes are the best I have seen. Not sure about your maths though,3/4 inch @ 1/72 scale is about 0.265mm if my head is still working. Glad to see you back in the shipyard.

Cheers JJ..

The torps were based on an existing model, which I adapted. So I had a baseline to work with. The depth charges et al are scratch.

Maths: of course you’re right. Don’t even understand where I got the extra decimal from.

Hey,

what a piece of work ...Amazing. Beautiful. Many thanks for showing ...

Cheers

Nicely detailed parts, Marco.

Thanks for all the support. Most importantly, I’m back at the shipyard.

I have another serious hobby: astrophotography. I’m setting up to go remote, which means I’m basically using the same side of my brains as for design in Fusion. Lots of tinkering and staring at a monitor. I have a few more chores, so D805 will go a little hop scotch. But I’m close to having all I want to glue in place, after which it becomes more like regular model building.

 

[Marquinius]

This will need a little additional work to make it look the part, but for a first print I’m happy. I didn’t know there were so many variants of this rack, but after careful examination of images of D805 and drawings, I can say it’s close. For size: that handle is 0.2mm (@JJ, I checked my math ;-0)

 

[Jack Jäger]

Looks absolutely brilliant!!! This is coming together really well Marco and you maths is getting better too. Love it, JJ..

Having learned my lesson with the first D805, with all the carley floats bursting resin over the complete ship, I made sure that I had no enclosed spaces. Sideline: and I’m rather happy I could do the ship again, now in 72 scale. For fun I included the supported prints. Gives you an idea how much trouble it is to get these finicky things off the actual print.

Next: hoists, derricks, walkways between islands, companionways, etc. Lots of interesting stuff to design and print.

Congratulations with this new attempt, Marco. The parts looks very nice.

Developing your own plastic kit: the blessings of 3D-printing.
Marvelous job with all the details.

 

[Marquinius]

This was as far as I got with the first D805. That was a 96 scaled model. A week later disaster struck and she was scrapped. Funny thing though: I haven’t reused and upscaled parts. I had learned so much, thatbi wanted to do better.

And I’m sure that at short notice I’ll be able to show similar progress with the new model. Almost there!

 

[RDN1954]

Changing scale is a daring move, at least it allows you to add more detail and implement lessons learned from the 1:96 scale model.

 

[Marquinius]

I created the derricks in 3D, but found out I somehow miscalculated the width: back to the drawing board. With most of the structure available, I have to "fight" for space, just like the real thing. It is rather crowded on deck. Oh well. Here is a 3D render, albeit wrong width/depth.



I also spent some hours creating the "Hazemeyer", Bofors twin 40mm. I borrowed an existing gun set and created all the rig around and on top of it. You'd think it's a little coarse, but the whole thing is about an inch high. I'm sure it will be interesting to print.

 

[Jack Jäger]

Your hazemeyer looks very impressive, have you had any luck printing it ?
Look forward to see the results.

Cheers JJ..

 

[Marquinius]

Ooohh. Exciting. Derricks on the right, Hazemeyer on the left. And as a first print on a brand new printer …

 

[Marquinius]

Aaaand … not too bad. I’m going to make some small changes to the design and reprint in a different orientation to prevent some minor delamination issues. But that’s because I like to tinker.

 

[Jack Jäger]

Very impressive.

JJ,,

 

[dockattner]

Very impressive.

JJ,,

Indeed.

 

[Marquinius]

Back on the drawing board, created all the little details that are mostly invisible but matter. Reprinted and gave it a primer in grey and black.

Happy man, me.
