Hello to all of you,

This ship will be part of a diorama including 10, 12 different ships. The theme of this diorama will be the preparation of a landing operation (I have not yet made the choice of the theater of operations).

The ships of the diorama will be :

- A liberty ship in military version (trumpeter kit + Arsenal detail kit and a lot of home-made cut-out pictures)
- Two LST (AFV kit + Infini model detail kit)
- Two destroyers
- An AM type hunter (scratch 3D printing and home-made PE)
- Three LCI (L) in different versions (scratch 3D printing and home-made PE)
- Two Canon class escorts (Kit Back cast model)
- L'USS GAGE APA-168 (Haskell-class attack transport) (scratch 3D printing and in-house PE)
- One Ashland Class Dock Landing Ship (LSD) (scratch 3D printing and homemade PE)
- Two LCTs (5) (Black Cast Model kit)
- and if I make the choice of an operation in the Pacific an LSM.

I already have all the plans and several hundred photos to document this diorama.

I will make one post per ship. Then a final post for the realization of the final diorama. The dimensions of the diorama will be about 120 cm by 50 cm.

Now let's come back to the title of this post (APA).

Here, I make the step towards modelism 2.0.

With the latest technological advances and capabilities of the new 3D printers, I decided to make a scratch ship with printer 3 and photo cutting.

I already master the creation of photo cutting and I have already made the diorama cranes on Russian ships in 3D printing.

The first challenge is the hull design with FUSION 360. It took me 2 weeks to get a first acceptable result. But I still have to solve two, three small problems.

On the bow and stern of the hull. The smoothing function of FUSION is very capricious and I still have some subtleties to discover. But I think I'm on the right track.

First the drawing of the contours and rails used to smooth the surface:

I redid the drawings multiple times. But with each version there was progress. So I persevered.

Then the smoothing function and the function to split surfaces:

Puis dans FUSION, il y a une fonction pour vérifier que la surface de présente pas de déformation :

more in the next episode.

Friendly.
Alain.

Hello,

No, I don't have the complete plans for this vessel. I am still looking for them but they are hard to find. If you have any leads I'll take them.

However, I do have the plans for the LSD 22, LSD 25 and LSD 26 of the Casa Grande class.

Friendly.
Alain.

Very interesting, my 1:120 APA US Randall 224 is made with mostly traditional methods (No commercial pats) but I am backfilling with some small 3D bits. Not using Fusion 360 yet, but would like to make some new LCVP's. My hand built ones are decent but a little "fat".

Have fun, a very involved ship! Mine is over in scratch built projects! Cheers: Tom

The Navy's Booklet of General Plans for the Haskell class APA is at https://www.hnsa.org/wp-content/uploads ... apa170.pdf. This is not perfect for model building but can be helpful, anyway.
Best wishes,
Rick

More detailed drawings are available on the USS Lowndnes website. Navsource photos are also useful, though not generally the distant whole ship photos, but the ones taken onboard showing some particular activity.

Good Luck!
