AA guns on upper deck
« Reply #32 on: 22 Jan , 2016, 18:39 »
d) Yes, both the 2cm guns were twin-barreled

Hmmm...
Are there pics showing the boat had 2x TWIN-barrel guns?

There are archive photos on www.uboatarchive.net that show the upper tower guns as SINGLE barrel Flak C/38 on L 30/37 mounts:

(near bottom)

Not knowing a lot about these things.. are there good photos or illustrations to show me how to modify the kit guns properly?

Glenn, pictures 2,3,7 from http://www.uboatarchive.net/U-190A/U-190Photos.htm show:
a) the shield of the starboard AA gun which was meant for a twin gun mount (pictures 2 and 7)
b) the mount for the port MGs, an M-43 U zwilling (twin) mount for the coupled AA guns (picture 3 + this picture: http://webberswarships.ca/styled-24/files/u-889-along-side-u-190.png).
In the other pictures from the same web page you can notice that, for reasons that I ignore, the boat only sports one of the two C30 (or most likely C38s) on the gun mounts: we can speculate that half of the guns were dismounted after the armistice (they were later removed completely), but of course on the basis of the available pictures we can't have the certainty the U-boat had been originally fitted with only one of the two guns per mount. I am pretty sure that if the boat was in her standard configuration before surrendering, both mounts would sport 2 MG C /38s each. 
By the way, are you going to represent the boat on her service days before the armistice or after the VE-day?

Hi SG,

Likely I will show the boat as it was surrendered... I like the pic of the RCN crew putting both flags on the periscope and may try to mimic that.
But ultimately I think I will go with your reasoning... that both barrels were on each gun at that time.    In thinking about it more, there was no reason both wouldn't be there in operation.
Ahhhhh yes, the problem faced is one of timing... there are no specific dates on these photos.
Thanks for the clear thinking.  :)

Hi Glenn,


Yes even pictures with dates marked on them can be misleading, I have a collection of photos with dates on them, on further inspection the dates are of that particular boats sinking not when the photo was taken.
I see no reason as to the U190 not having 2 2cm guns on each mount, event if one had failed during the patrol it would have been left there. I have yet to find an in service picture of a boat with different shields on each mount, but that doesn't mean that such a beast doesn't exist.


Regards
Jon

This really calls into question the things that I want to do with my build.  :P
Like... pics show the protective "rollcage" above the twin 3,7cm cannon... is not there.   Only a small bar near the flagstaff is shown.
So what did it look like on the day of surrender... was it there?

Schnorkel well... accuracy vs. simplicity
« Reply #37 on: 25 Jan , 2016, 10:02 »
Just when I thought I had a handle on the whole "schnorkel well" thing... a new twist turns up!

The schnorkel well included in the Revell kit is quite simple... it's a big 5-sided box with an open top, some big ribs, and an area for the pivot.
The RC Subs detail set includes some fine details for the well.

I reviewed the kit instructions & PE set instructions.
From reviewing the instructions and a picture of the schnorkel well, I determined the following:
  • Right-hand outboard well wall (kit part #204) will NOT be put in place, rather some PE ribs will be put in place on the right-hand side.
  • The lower 'ledge' on which the RH ribs (S1, S2) sit is right above the hull main flood holes... but the bottom of the well is below the hull main flooding holes.
  • There is no picture of the left side of the well (inboard), so I do not know what it looks like, or if it is even there.  The PE set instructions seem to indicate there is no wall there.
  • The pivot areas MUST remain in place
This raises several questions on how to construct the schnorkel well.  I have a feeling it will end up being a skeletal structure since water had to flow through there.

There is a method to my madness:

Progress on schnorkel well
« Reply #40 on: 01 Feb , 2016, 07:58 »
I made some good progress on the U-190 schnorkel well in the past few days.   
There is a lot of cutting & scratchbuilding, and PE details. 
Hopefully the results will be worth the achy shoulders & achy brain.


Updated my U-190 build site:  http://gc-scalemodels.ca/U190/

Progress on schnorkel well - 02 Feb 2016
« Reply #41 on: 02 Feb , 2016, 07:24 »
More progress on schnorkel well.

  • added lengthwise stiffener to LH well assembly to prevent warpage (0.040 x 0.156" strip styrene)
  • opened main flooding channels near schnorkel well (since I would not be able to do that after I started adding PE details, etc.)
    Instead of thinning the plastic from behind (which would have destroyed the bottom edge of the channel), instead I used a high-speed cutting wheel from the outside, then sanded the channel to shape.  The result:  clean-looking open flooding channel, preserved inner bottom edge.
  • Shaped & modified the RH (outboard) schnorkel pivot.  I opened many of the holes, and then added styrene pieces (bottom floor of channel to bridge gap between hull & pivot, and 2 thin vertical ribs in line with rivet rows)

Schnorkel Well progress - 10Feb2016
« Reply #42 on: 10 Feb , 2016, 10:19 »
Added RH ribs to schnorkel well... all 15 of them (two PE parts apiece).

Remaining:
  • add small baffle plates in flooding channels (0.010" styrene)
  • complete the pivot area
  • add piping components inboard of schnorkel well well... since that inboard wall is open & everything behind it is viewable

Schnorkel Well... COMPLETED
« Reply #43 on: 16 Feb , 2016, 10:49 »
I have completed the construction of the schnorkel well... <WHEW!>


Completed the pivot area, shimmed it so the deck mates with it properly.
http://gc-scalemodels.ca/U190/images/Well_pivot.png

Added L-channel support bracket along outer ribs, aligned to support retracted schnorkel.
http://gc-scalemodels.ca/U190/images/Well_L_channel.png

Added large piping inside of inner ribs, to mimic likely structures (also to block the empty spaces between inner ribs).
http://gc-scalemodels.ca/U190/images/Well_piping.png

Added 0.010" baffle plates within main flooding channels (2 baffles apiece).

Started to add PE flood hole templates to the hull.
