Hi Aop,
The hull is coming along very nicely, and it looks like staggering the cladding is working out much better. :thumbs_up_1:
Good luck with the concert!
Regards,
Phil

Thanks a lot for the kind words! All worked out well, thanks to the great advice on this great forum.

We'll do our best at the concert, too :big_grin:

Thanks Steve!

My 3D printed items arrived three days ago, but I didn't have time to post anything at the time. Here are some photos of the parts after cleaning in warm soapy water:

No.2 platform:

Image

Signal Deck & conning tower platform:

Image

Admiral's bridge:

Image

Upper bridge & compass platform + director platform:

Image

Edit: forgot the directors and mounts!

HACS directors:

Image

Y turret director:

Image

And finally, the mounts for the aft pair of HACS:

Image

Note: the HACS and Y turret director are the only parts printed in frosted extreme detail plastic; the rest is printed in frosted ultra detail plastics

I must say the new parts look really good. I designed all the splinter shields to be 0.3mm thick (Shapeways minimum thickness) and even thinner at the outer edges of these and also the ventilators on the bulkheads of the no.2 platform. I thought it wouldn't be printed well, but they came out very nice!

I have primered the parts already. Here are some pics:

All parts (except the directors) need further refinements. I will sand and grind most of the rough surfaces. Then I can add details.

Cheers! :wave_1:

Hi Aop,

Must be good to finally get the 3D printed parts! Cool :cool_2:
Looking good!

Phil, indeed they are really good. Even more impressive than the last time we ordered...Shapeways might have done something new...
Here are some shots of the dryfitted 3D upper superstructure.

Before the 3D printed parts arrived, I spent some time assembling the Pontos crane. It proved to be extremely difficult as I did it a year before and damaged a few things. Bad side of being a kid! The crane disintegrated several times during the construction and redoing never seemed to end, just when I put my hands on it!!! The small rails on the crane shaft (?) got a lot of damages way back as well. I left the piece out of its fret and the heavy things were dumped on it in the cupboard for months! I'm glad the rails just broke off and nothing too serious happened! Oh well, I'm complaining too much now... :heh:

I also added doors details

Here is the Pom Poms director platform underway. Details added and portholes drilled. This structure really costs me a lot to buy more PE doors! 8 doors for such a small structure!:

Cheers all and thanks for looking in :-D ,

As per DavidP's advice, I ripped the splinter shields off and sanded the glue spots smooth. Then replace the circular platforms. This time, the shields are wrapped around. Here is the result :smallsmile: :

Hi Aop,
Yes the 3D parts look very well made, they are so smooth and it looks like they have done an excellent job. And of course assembled, the superstructure looks so good!
I don't know much about 3D modelling but if I've understood you correctly, you actually "drew" the superstructure parts on your computer? Is that correct? Well that's pretty clever, I can barely draw a straight line in 'Paint' and that has a straight line tool! LOL :big_grin:
And then you send the file to Shapeways who 3D print it for you.
So how do you draw them on your computer and is it difficult? I suppose I should Google that one because it is very interesting.
Keep up the good work, looking forward to seeing more. :thumbs_up_1:
Regards,
Phil

Hello Phil!
Yes I am very happy with the 3D parts. They are really fine as we see, thanks to Shapeways!

Regarding the designing stage, it is not difficult at all! Of course it might be a bit unhandy at first. I use a software (program if you like) called 123D Design by Autodesk, which is the same software used by Steve aka ModelMonkey (and he was the one that recommended this), but he is far better! Actually what is involved is not just 'draw', but extrude, loft, fillet, shell, merge, subtract, etcetera, to shape up objects. Drawing a straight line is very easy in this software (and any software actually.) At least doing so is easier than MS Paint where you have to check the alignment very carefully and not moving the mouse! There are many tutorials out there on Youtube on using this software. Also note that it has some limitations too. It is easier to use comparing to other more complex (and expensive) CAD programs, but is unable to design things too complex, for instance an accurate hull. Nevertheless if you are using it for the basic parts, this works really well. Not to mention that it can be downloaded free of cost and is capable on both Windows and Macs.

Yes I 'upload' the 3D files to Shapeways. They accept STL, OBJ, X3D, DAE, Collada or VRML97/2 (WRL) Then after uploading, you could scale them, fill in titles, descriptions, render poses, selling, price, etc. Then you got a model uploaded on your shop! :thumbs_up_1:

Best wishes!
Aop

Phil,

The forum has a "Virtual Ship Modeling" section where folks post information about 3D CAD modeling and creating 3D printed parts. You can ask questions about 3D CAD modeling/printing if you want to know more.

Hi Phil,
Thanks for that. I just checked it out, very interesting.
I must confess I know nothing about it so I tend to ask questions before thinking of looking for myself, lol!
I also find it quite remarkable that Aop could "draw" them himself in 3D on the computer. For someone who knows nothing about it, it seems quite amazing as well as interesting. So now I'm letting my ignorance show, haha.
Cheers,
Phil

Don't worry Phil! These new technologies are quite difficult to understand for newbies (including me!) I must say DrPR is a very skilled CAD designer. His USS Oklahoma City is amazing! You could see his works here in this thread: viewtopic.php?t=70810
I think you could learn tons of stuffs from him (and also others) if you are interested! :thumbs_up_1:

That is an overrated comment! Anyway thanks!

I am trying to find the right putty for the hull, as I figured out proper modelling putties wouldn't do for such large areas. But then my dad bought me a wall putty! I will need to return this and buy another type from the shop. Maybe an auto putty?

Hi Aop, Well done on your 3D designing and having it all come together so well! I don't know how you guys do such a fantastic job working in these scales! I take my hat off too you all. Scott :woo_hoo:

Another great master commenting on our build!! Thanks very much for looking in. :big_grin:
Actually, we're the last on the list of small scale ship builders. No complete ship under the belts, and we're just 15...still have time to fool around, though!

My brother and I also had a dream of building huge RC ships that could sail in the sea! As large as 3 - 4 m long. But as it proved - no material...and zero skill... Plus, our mom wouldn't allow something like that...Mother naval treaty!! :heh:

We haven't made any progress on the Lion for nearly a month...as modelling time just got filled up with 3D design projects...

As you might see in some photos, the current hull planking looks somehow wavy. We figured out that the Garzke and Dulin book hull plans are obscure at places. The specified spacing of ordinates were incorrect and will result in a completely wrong hull shape. The ordinates laid for this hull were estimated by matching with the deck edges, and even though this seemed to solve the problem to an extent, it still turned out bad. We are now looking into the NMM plans. They have hull lines, breadth lines, and body plans, which would be perfect. So this means we need to build the 5th hull!!!.....
:mad_2: :mad_2:

Before doing anything, we looked into laser cutting for the hull frames, profile and deck plates. This will save a lot of effort and time cutting them by hand (we've done quite a lot for the previous hulls!). The shop charges 20 Baht (or $0.572) a minute, so not an expensive stuff at all. Also, the alignment will obviously be better.
Hope we could get this build going and post more updates soon!

HI aop aur.

i was wondering if you can share the HMS lion class progress.

it's been a year since u posted last page and i was curious how did it go.

thank you
