Important subassembliesI glued the tower halves together and stepped out of the suggested construction order. My reason for this deviation was that as a couple of (very much) protruding pieces were to be glued into the sides, they would only be badly on the way while I would be twisting, rolling and turning this chunk around. They would also be in a grave danger of being knocked off or even broken, so I thought it'd be much better if I just glued them on a few iterations later.
As the last thing you can see in this set of photos I glued on the rungs of the ladders as well as the handle and the hinges of the hatch in the front. While they were curing I grabbed a good hold of the rest of the hull and filed/sanded the putty mess and the ugliest seams away.
My next step shall be to glue the tower onto the hull and whenever that has been set I guess I'll finish up with the antennae and last details of the conning tower. After that I'll resign myself to fighting the photoetch pieces, hoping I don't end up swearing like a drunken pirate.
