Lower hull is painted in RAL7016. Turned out good and the rivets look nice....

O.K., I have a few weeks of filling, grinding, applying details and rivets and cleaning behind me, and yesterday we finally could paint the upper hull in RAL7001. Here are the first impressions. I'm rather pleased.

O.K., spent two weeks with filters and washings to weather the upper hull. I did a subtle job and on the photos it looks even more subtle. I'm not a big fan of weatherings that look like the bot got sunk five times. I hope the washings and filters will go well together with the acrylic clear coat I'm going to apply next. Well, we'll see. Next is the weathering of the lower hull. As it is les detailed, it should be a quicker job than the upper hull.

And on we go.....the machine frame is ready.Here some pictures. Just the receiver, gaskets and bellows, and then I can check if everything is watertight.

Also additional work on the upper hull. Finished the mechanics to extend the snorkels and the chain drive of the upper rudder. The snorkels are actuated via a Firgelli linear servo which is located in an watertight compartment below the conning tower.

Wow, I love it, DrSchmidt. Amazing presentation of an amazing build! That's the first time I've seen the Archer rivets on a model. They really look good.
Warm regards,

Tha Archer rivets work great. But one must not forget to seal them with microsol before painting. Otherwise the transparent carrier film will start to dissolve and that doesn't look nice.

Well, the submarine test pool has been installed :D

Image

And the first tests of the WTC have been performed. So far everything works fine. Tomorrow I'll conduct a harder test program.....

Tnanks :D

I'm going to start to balance the boat today. That's going to be interesting......

O.K.: The boat is almost ready. Only some ropes are missing, but for handling reasons those will be added later. Next is the balancing of the boat. So here some photos:

Image

Image

The upper rudder is driven by the main rudder and thereby also drives the push rods and chain drives that used to actuate the rudder in the original:

Image

The snorkels can be extended and retracted by a linear servo:

Adding buoyancy via pu foam did the Job. First time the boat floats on even keel and at the right water line.
