Thank you so much Maurice! We are in complete agreement.

Just this week, I have been in a discussion with a customer who ordered a set of costly 1/32 scale torpedo tube breech doors of my design for his Lindberg PT-109 kit. He was very surprised to find that the breech doors were significantly smaller in diameter than the Lindberg torpedo tubes, by a whopping and very noticeable 12%. He wrote to me and asked if perhaps there was a mistake in labeling, and that the product was actually intended for the 1/35 scale Italeri kit because the 3D-printed breech doors fit his Italeri kit perfectly. I was concerned!

Fortunately, the 3D-printed breech doors I designed were scaled from scans of actual 1942 BuOrd drawings made by Electric Boat, the designer of the real breech doors (see reduced image below of one of the drawings), and are fully dimensioned. Unless one can measure the real object, references don't get any better than that!

After checking my design against Electric Boat's drawings to see if I had made a big error, what we discovered was that the 3D-printed parts were in fact designed perfectly to 1/32 scale. And since neither the Lindberg nor the Italeri kits' torpedo tubes match the Electric Boat drawings in diameter, it is my opinion that both the Lindberg and the Italeri kits' torpedo tubes are over-scale in diameter.

We can only know that both the Lindberg and the Italeri kits are over-scale because we have the fully dimensioned original 1942 Electric Boat drawings to compare them to.

To help any Lindberg modeler who would like to have the very detailed 3D-printed breech doors but not have to buy the whole 3D-printed torpedo tubes, a different set of breech doors that are intentionally 12% larger than scale are now available and appropriately labeled as specifically over-scale just for the Lindberg kit. The modeler can choose which of the two is best for his or her 1/32 model.

Good news, if by "final fit" you mean how the island looked during the Yamato sinking, the 3D-printed 1944-1945 island is accurate for that event. Link: http://shpws.me/Pmpv

If you mean by "final fit" the enlarged bridge, enlarged flag plot and changed radar platform, please be advised that the change was likely completed during a refit that occurred from July-September, 1945 to repair hurricane damage. The change was completed too late for further wartime service. It is essentially a post-war configuration. Is that the configuration you would like? If so, I can probably have that ready for you today.

We know that Hornet was deployed for 16 continuous months until she was seriously damaged by a typhoon effectively knocking her out of the war. During the 16 months of operations, photographs indicate no major changes to the island were made during that time. She traveled back to San Francisco for repairs arriving there on July 7th and that's when the island was modified.

Here's what I think probably occurred to the island during that July-September repair/refit (based on the photo dated January, 1946 shown below):
1. forward Bofors tub removed
2. flag plot enlarged
3. original navigating bridge retained but her deck and splinter shield was modified to match the enlarged flag plot below. The deck and splinter shield shape looks much like Yorktown's 1945 fit, not the "wedge" we see on other ships.
4. radar platform was changed
5. island Oerlikon platforms were changed to reduce the number of 20mm guns and provide for positions for Mk.51 directors controlling three new Bofors on new starboard side hull sponsons (looks much like Lexington's shortened platforms)

Please let me know if you prefer the September, 1945 appearance as seen in the photo below dated January, 1946.

Hi Steve, sorry I should have been a bit more specific. The island I am after is the configuration as the Apollo 11 recovery ship, basically as she sits now in Alameda.

Mistake is mine. I've been working on WWII islands this month and have that on my brain. Sorry about that.

Which scale would you like it done in?

Steve, have you thought of doing any more recent U.S. Navy upgrades? I am particularly interested in Ticonderoga class cruisers as the Dragon models need a lot of help.

I am making some progress, too, on the island! Although Essex islands are technically challenging and every island is different thus very time-intensive to design, it is coming along nicely thanks to the availability of good references. Thanks for your patience! Once Hornet is complete, I will have to move on to other subjects.

Hi, Walt and thanks for your interest and patronage!

Regarding upgrades for modern subjects, I generally stay away from those subjects for the following risk management business reasons (sorry about the long answer):

1. Modern original equipment manufacturers may demand licensing fees. For example, Boeing, General Dynamics, Raytheon, etc. all insist on receiving costly licensing fees (which is also why I do not design model aircraft, modern model tanks or model missiles). A single fee demand from Boeing's corporate lawyers could be more than the annual gross income for my entire business.

2. Despite reason #1, there are other designers who accept that risk and do specialize in modern subjects. Sales data and unhappy experience prove that the market is too small to directly compete with other 3D designers. If other 3D designers already have something available (good or bad), the already small model ship market will be split spoiling the possibility of generating enough sales to pay for the research and design time for both vendors. (That in fact happened with my HMS Hood turrets. Without knowing, both Micro Master and I independently designed and released Hood turrets the same week. He and I now very closely coordinate with each other before releasing new designs. I defer new requests for Royal Navy subjects to him.) Furthermore, to cover the cost of research and design, the object would have to be made available and sell well in more than one popular scale, say 1/96 and 1/350 scale and 1/700 scale, too, in order to appeal to enough modelers to generate enough sales. Sales for a product in one scale can be spoiled by competition in another scale. Say a 1/96 customer wants a product not produced by any other 3D or resin vendor. But the object is produced by a vendor in 1/350. I will probably have to decline the request. The 1/96 market alone is either too small or buys too infrequently (or both). Modern 1/350 upgrades are dominated by resin aftermarket vendors and other 3D designers. Therefore, with 1/350 sales dead for that subject, the subject is not likely to generate enough sales across multiple scales to pay for the time necessary to research and design it for 1/96. For example, Veteran Models already offers highly detailed resin and photo-etch upgrades such as SPG-51 radars and missile launchers in 1/350 scale ruining the possibility of any 3D-printed sales for those objects in 1/350. Without 1/350, 1/96 alone isn't enough.

3. Finding authoritative, dimensioned 2D drawings from which to make designs of modern subjects, particularly electronic gear like radars, is very difficult at best since often the manufacturer's 2D drawings are still classified and therefore unavailable, which leads directly to:

4. Lack of authoritative references requires an exhaustive, intensely iterative (trial and error) design approach that becomes too costly to produce a "sell-able" design. In other words, without fully dimensioned, authoritative 2D drawings, the design would have to be made from photos alone. This would likely require a considerable and costly research effort to find suitable views from which to determine dimensions (costly because time = money). Since overall dimensions cannot be determined with any certainty from photos, dimensions and feature size would have to be guessed at or assumed in order to complete the design. Guesses and assumptions are often wrong, only improved through a complicated and lengthy design process of trial and error. Despite that effort, too many guesses and assumptions would certainly result in a noticeably inaccurate design the market would reject. Modelers who know the object well, particularly Navy vets with experience with the actual object such as a radar or missile launcher, would recognize the errors and refuse to buy it. In their frustration, they may choose to point out the design's inaccuracy publicly rather than offer assistance to improve it. Willing subject matter experts may be unable to provide assistance for reason # 3 above. Unfavorable public reviews on modeling websites and social media unnecessarily cast doubt on other products that are very accurate, spoiling sales for those products, too.

5. World War Two subjects sell best. Modelers buy 30 Yorktown CV-5 class islands for every one Cold War-era Essex or Forrestal island that sells. Yep, that's 30 to 1. I thought that as I completed and offered more Cold War-era subjects that together they would increase in popularity, especially with so many Cold War vets who enjoy modeling. But that hasn't yet happened.

For these reasons generally, modern subjects are problematic at best. They are too costly to research and design, would result in noticeably inaccurate products modelers would reject, and expose the business to costly licensing requirements risking attack from corporate lawyers. Modern designs, IMHO, pose too much risk to the business as a whole.

I wish it weren't so.

Many thanks Steve, I look forward to getting my hands on it!
Also would it be possible to have a name plate made at the same time? As I am using the Intrepid kit as the base, that one kinda won't do haha.

Do you think you might do the aft AA (1.1) gun tubs on the Pearl Harbor BB's in 1/700 the Dragon kit has them wrong and molded to the deck and so do the resin kits of Nevada/Oklahoma also I believe the Big 5 kits from Trumpeter are wrong.

The gun tubs look like a great addition.

Eager to see what you do with the DKM cranes! Hoping that the DKM Admiral Scheer superstructure is not too far down the pike.

Hi Steve,

Have you, or intended to do a bridge of LPH-6 Thetis bay in 1/700


Best regards
Bjorn

Hei, Bjørn,

Jeg har ikke laget noen øyer for eskorte flybærere eller lette flybærere, men jeg vil gjerne. Jeg legger dem til køen. Kanskje modellere som liker å bygge dioramas med modellfly, vil ha en på 1/144 skala.

Det vil vare en stund før jeg kan komme til designene. Køen er fortsatt ganske lang. Se: viewtopic.php?f=16&t=164638

Forresten ble farens besteforeldre født i Oslo. Hilsener fra North Carolina!

Takk for din interesse! Vennligst unnskyld min dårlige norske.

------------------

Hi Bjorn,

I have not designed any islands for escort or light carriers but would like to. I'll add them to the queue. Modelers in 1/144 scale could use one in a diorama with aircraft.

It will be a while before I can get to the designs. The queue is still pretty long. See: viewtopic.php?f=16&t=164638

Thanks for the interest!

Hi Steve,

tusen takk for svar, ingen problem med køen. Jeg kan vente.
Kult at du har norske aner fra Norge, hadde en liten mistanke om det siden du heter Larsen til etternavn. samme etternavn som meg Bjørn Larsen :thumbs_up_1: :thumbs_up_1:

Takk for din tålmodighet, kusine Bjørn!

David, it would not surprise me to discover we had common Viking ancestry.

Watch out, Bjorn and I might plunder a monastery. :cool_2:
