And just a few of hours later......

Incredible detail and it's quite amazing that you can materialise your ideas so quickly and with such apparent ease.

Yes Richard, it's magic! 😍

 

Painting the LCVP again, I was not satisfied, I applied a very light veil of Ocean Grey to attenuate the patina, it's much better and it makes it more homogeneous, a solution to remember. Long live the airbrush!

I painted the platforms and the forecastle to see what it looked like, I'll have some details to review and do including the front flagpole and its platform. I still have two fairleads to glue in the making.

I placed a temporary anchor chain to align stopper and windlass. We'll see if the chain ordered fits the stoppers.

I started to draw the 40mm Bofors gun, thanks to a friend for documentations, in part.

The design of the 40 mm Bofors canon is almost finished, I limited the details to optimize the printing for 1/200. It took me a little time because there are a lot of elements.

 

I still have some details to adjust before printing. The railing will be in PE.

I tested a first animation fonction with my 3D software Fusion 360, I'm groping :

I was able to start a series of impressions of the cannon, I made several tries to try to master it as well as possible, but it's small and not easy. The limits of the impression are there. It doesn't matter. 

 

I had to raise the base as well. 

 

The cannon tube didn't come out correctly, while many other smaller and finer details came out well, like the footrests, the seats... So I cut and put a brass barrel tube I had in stock.

Lovely. So, to put things into a little perspective, how long would you say that that Bofor took to do from start to finish; drawing, printing, correcting, reprinting...

The 40mm Bofors is exquisite! Like Stuart, I'm also interested in the timeline for doing this piece.

 

Thanks

Charmant. Donc, pour mettre les choses un peu en perspective, combien de temps diriez-vous que Bofor a mis à faire du début à la fin; dessin, impression, correction, réimpression ...

 

Stuart 

Hello Stuart, Terry, I don't know exactly, a retiree doesn't count his hours... 😂 I would say about more ten hours for the drawing, printing 2 hours. 
The advantage is to clone after the cannon as many times as you want and at the scale you want.

 

In fact I just found my mistake about my firt print, the barrel tube was hollow and therefore very thin, hence the collapse during printing, yet I had checked ... it is by increasing the scale to 1/48 directly with Chitubox, the program that generates the file for the printer that I realized the thing, I will reprint to be compliant.

I'm dragging my heels a bit at the moment, I spend a lot of time on the guns, because there's not much 1/200 on the internet for me, even at Shapeway, it's not very good in terms of definition, so I'm sticking to it.

 

I start the design of the 3 inches / 50 ( 76 mm) guns, they are placed (2) on the front platform and 2 at the back of the ship. A new big job, but I have what I need in docs. 

 

Here is the latest version of the 40 mm Bofors. I have already printed a 1/48, the printing is superb, but then I took the drawing again to add some details it was missing a little bit.


The 1/48 test.

In the history of the United States Navy, several 3-inch, 50-caliber guns existed and equipped U.S. ships from the late 1890s to the late 1990s.

Declined in several models ("Mark"), we can count 3 historical evolutions, which were mounted as anti-torpedo or anti-aircraft guns in secondary artillery of battleships and cruisers, in main artillery of destroyers, or as submarine guns.

 

Mark 10 - 22

Most of the guns of this series were used as anti-aircraft guns, the first being built during the First World War. 

Widely used until the 1930s, they were gradually replaced by 5 inch/25 caliber guns and then by 40 mm Bofors. 

During the Second World War, they were the main armament of small ships, such as escort destroyers, submarines, merchant ships and oil tankers. Thus, 14,000 units were built between 1940 and 1945.

 

 

The documentation I retrieved to draw it, it is more complex than the 40 mm Bofors.

In the USA everything is allowed! 😮

 

 


 

Printing of 2 1/48 Bofors barrels for fun. 

 

There are sailors in 1/48 that could make a nice scene on a double platform. I will keep this in stock.

This 3-inch cannon is taking shape, but there is still work to be done. I have work to do on my 1:1 scale cars, it's holding me up...

There will only be one 5 inch (127 mm) left on the rear platform to design unless I buy one from Distephan to see the quality:

Printing: The result is quite good, the tractor saddles are printed, it's really fine, especially the vertical feet at 2/10 of a mm. Can't wait to have the Phrozen 4K at 37 microns for small parts.

I just received my Tamiya de-grappling pliers from Japan directly and quickly, because they are a bit cheaper than in France, shipping included, you'll have to explain me... Nothing to do with my Faller.

I had received my first decal board ordered from the excellent Oups pour le LCVP, it looks good, good quality, I'm waiting for the matt varnish to homogenise it all. 

I broke a few parts when I was removing the jamming from the barrels, no problem, this is a test series of two to see what needs to be modified. I'm reprinting 12 of them with 20 micron passes instead of 50.

I received the anchor chains, I had to redrill the stopper holes, not easy without breaking anything, but it's good, it looks good. There are still the anchor grips to make.

 

The front gun platform is finished, I'm waiting for the NorthStar firing director, it's not easy to get it from them!

I started to install the piping that is supplied and of different sections, Ervergreen tube, piano strings, everything goes through it, that's what will give finesse to the details for the bridge.

My father too, Kev. (Merchant navy tanker)..

 

My father in the engine room on the french tanker "Kirkouk", he was second engineer , main steam machinery was replaced by 2 strokes diesel engine Stork.

This is the only picture I have of this ship... T2 clone.

I am now struggling with painting, a dazzle is always complicated and long to paint. I also made progress on the front pipes, but I still have some to install.

 

I started painting to find the right method. Black is Tamiya, easier to apply than LifeColors. There will be an antifouling, there was USN red or black.

 

On the Dazzle measure, there was no antifouling, but I think they didn't bother to represent it. On the photos we can see that it does not mount very high along the hull so that the camouflage remains effective, probably, on light ballast. 

 

USS Tamalpais (AO-96), veterans of the tankers pose in front of this very beautiful model, we can see a paravane on her launching mast, it will be reproduced also but at the sea station, although..:

Black here on the Pamanset, or just a black stripe and red underneath??? This is also a possibility.

I have kept the hull defects, I could have erased them as elsewhere, they will be useful for the application of the patina, the bow plates are often deformed by the pressure of the waves... This can be seen on the photos above.

Today drawing of the foremast, 3° backwards inclination, with its crow's nest and the hydrocarbon vapour discharges from the cargo tanks, the ladder to climb it will be in PE and also the winches for manoeuvring the cargo derricks. I have simplified it. Not too many pictures of the machine.

 

That's all I have:

 

This one looks a little bit like it, I could be inspired by it.
