Excellent work on the rudders Karel.  that's exactly what the rudders and other cast parts look like on the steel-hulled boats around here.

When going into that detail, you might also want to add a sacrificial zinc anode to each rudder.

In real life, the anodes could be almost any shape, from teardrop to rectangular.  They were udually placed on the rudders between 1/3 and 1/5 of the way down from the top, and 1/3 - 1/5 from the leading edge.  Not sure if there was one on each side of the rudder or just on the outside, but I've seen them in several photos.

The reason for the anodes is to use a 'less noble' metal as a sacrifice so that galvanic electrolysis dissolves the anode instead of the more valuable rudder.

I've also seen these anodes on the propellor shaft supports and the dive plane supports.

Not sure why, but they only seem to be around the stern of the U-boats, not the bow.



Pat, do you have any reference pics for me from the anodes?





Thanks,


Karel

Wooow! Thats a detailed boat! Simply amazing!

If I remember correctly, the whole hull of U-995 has those little holes/rough structure...

Will do that Rokket  ;)



With the help of some pics i added Archer transfer welds and gave the rudders a coat of grey too see if the steel texture still would be visible after a layer of paint; i am glad that`s the case  :)

I am still not sure about a thing; the drip channels...
I think i found prove that there were drip channels on the type VII, so i am still considering to make these on my boat.








Can you guys shine your lights this subject and on these pics? The last pic is actually from the 995.

I found a clear pic to prove that indeed there were drip channels on wartime VIIC/41`s.
On the backside of the Revell instructions i saw this pic of U-1105.

Hi Karel

I am not 100% sure on the drip channels, I have not research this yet. But several things make my think about it. Why would you need a drip channel that sent 90% of it time under the water.

I think what looks like drip channels are attachment strips for the bow/stern casting cap for the saddle tank & hull casting. In some pictures you can clearly see holes that are for the rivets to fix the casting cap on to the saddle tank, and you can see a fixing strip on the pressure hull.

In this pictures you can see the fixing strip (with rivet holes) along the pressures hull to fix the hull casting to. You can also see the fixinging strip around the casting cap of the saddle tank.

Your explanation does make sense Simon, i don`t know exactly what the purpose was of these strips, fact is that they were there so i am gonna duplicate them.
Here`s a pic from the 995, maybe its of some help to you?

Based on these photos (I can't remember where I got them), U-995 didn't have those channels initially when put on display:

Hi goose814 and welcome aboard!

They are great pictures!! They must be sometime early 70's just after U-995 was put on display. In the second picture you can see the original bow!! I don
