OK so it is time for the 4 hours of bench time (not consecutive) update.
Lower hull and decks assembled.
There were a couple of small spots where the deck just simply would not meet flush with the hull. Keep in mind that these small gaps are about the width of a hair not the trench it looks like here. Paint would likely fill them but I gave them a swipe with some clear parts cement just to make sure.
Now, let's discuss the elephant in the room!
This kit was designed and built in 2006 (Thanks Scalemates) NOT 1966. They have completely beautiful, crisp, scale details. Just look at that deck above.
So why? Just why, did they feel the need to festoon the hull with massive (in scale) rivets and raised panel lines? In scale those rivets are about 4 inches around and protrude about 3. The panel lines are more like 6 wide and 3 high. Not only is this sub going to lose about 10 knots on the surface and be almost immobile submerged it is going to make so much noise while underway that the invention of asdic would never be needed.
If this was not going to be a quick build I would have spent a couple of days sanding all that carefully molded detail off. You just would not see any of this in 1/144
Tower detail is nice. This is where some photoetch may dress it up a bit but not a lot since the molded parts are actually pretty nice overall. That tiny grating and wood bulkhead paneling will pop with a wash.
The rails are of course a tad overscale and need some serious cleanup but thing they will look good once done. Luckily the styrene is easy to work with being neither too hard nor soft. It would be Goldilocks approved
