IJN Mogami Light Cruiser 1/700 Tamiya + add-ons

I present to you today my build of the Mogami in its Light cruiser configuration.
The kit is made by Tamiya, which means it's nice and I don't expect any major assembly problems.
However, some details are missing and the flak parts are really too crude. You get the feeling that Japanese manufacturers have pooled their efforts on these clusters and that they're showing their age...
So we're going to add some trinkets:
the 2 Artist Hobby PE sets (the only ones for the ship in this configuration)
A PE board for the lino deck battens, as on my 1/350 Maya, but this time at 1/700... yes I know, I'm a nut
127mm turrets in 3D :
The 20mm triple :
Back to work!

The small plates are fitted...
Now we paint in Tamiya lino brown with my new gaahleri aero, very pleasant paint, the trigger is very soft and pleasant, and easy to clean.
We'll wait for it to dry completely and then start sanding shortly...
gentle scratching
with my electric sander, using the finest tip:
In this case, I didn't use the automatic option, in order to sand as softly as possible.
parafilm masking : Check
Next step : we attack the PE !!!!
For those who are still hesitating, it took me between 15 and 20 minutes to do the 3 bridges... how long will it take on the masking tape?

Very nice work. I've always been curious about the Artist Hobby sets for these kits. Looks good. OTOH, I would never have the patience for the tie-down strips. Good for you.
It won't affect your build at all, but I just discovered that the Tamiya kits are 3.5mm too short.

Thanks Dan, I have to admit that I didn't measure the hull...
Anyway, it's going to be complicated to modify it!
Tha ArtistHobby sets are quite complete and easy to use, the PE parts are strong enough to be bend properly.
The next stage of the assembly is a very small one, but still, gluing the deck.
Not so easy, as the hull is very tight and the deck has to be held firmly during the gluing process to prevent it from popping out of its space...
mini overhang with gluing of 2 small railings and chimney grilles

Nor should it have crossed your mind. We all assumed its correct. After all, it's a Tamiya kit. I found this out by accident while comparing it to a Fujimi version.
Continued good work.

Do you plan to add railings on the funnel itself? I never know, they always looks so overscale, but people still add them, may be it is ok...
Progress looks great, i didnt follow what is the trick with Parafilm? Why is it better than other solutions?

The ArtistHobby set has no railings on the funnel
Regarding the parafilm, I find it easyer and much faster than the masking tape.
Also, as it has no glue on it, it can remain on the kit for very long periods without ruining the paint.
I made a tutorial (in french) here :

Excellent work so far, Yuth!
Questions:
- are you spraying ordinary acrylic paint on the styrene/brass surfaces without any preliminary priming? if so, how's the sticking of the paint/resistance to scratch? The pictures seem to suggest an optimal result.
- this is the first time i come across Parafilm M. It looks like an easy-to-apply material and you say it's time saver if compared to ordinary masking tape. would you give some advice/tips/do's and don'ts on how to use it?
Cheers,
SG

Hi SG
All the PE sheets have received some primer :
Regarding the parafilm, I made a tutorial here :

Last night, assembly of the aft mast began
The mast is up, the crane has received a small piece of PE that required 5 Lilliputian bends
This ugly pellet has received a little putty to disappear:
Let's move on to the crane, which will be replaced by a PE version:
We're on a piece of hell...
Each horizontal section has three folds, as does each vertical section...
and, of course, despite taking every possible precaution, the sections did not stay together.
After several attempts and a great deal of swearing (some of it exquisitely original), I gave up and will resume work calmly this evening...
It takes a big dose of masochism, though!

Looking good! I especially admire you trying out those linoleum strips - one of the few PE parts that i still don't have the patience for.

You can continue to avoid them, they're out of scale and relatively hard to fit... the next models will have these painted bars
