Tores mailbox VIIC and VIIC/41 operation and technical details

Seawater crossovervalves.
Below is Simons photo of U 534 showing the extensionrods of the valves. I believe the valves were of quite similar execution on the VIICs.

Tore, great found!!

Updated the valve this morning.

Hi Tore/Maciek

Do you think were was either words or symbols on the top surface of the 'T' handles hatches within the floor plating to show the way to open/closed the valve? Something like below.

Sorry I don`t remember so my advice is based on a marine engineers assumption. Signs telling which way to turn to open or shut an ordinary valve would be superfluous in an engineroom. I guess a sign would rather indicate which valve the rod belonged to.

Crossovervalves.
A small detail. I guess the valve spindles are a bit longer and it might be an universal joint between the spindle and the extension rod if you can figure out the details on the photo below.

I think you are correct, Tore. I rechecked my photo's and it look like a universal joint top & bottom of the spindle. I wonder if the Germans did this allow a little bit of movement when under depth charging

I just checked the length of my spindle and it was 535 mm I would not imagine then would be to long, but I do not know for sure.
 
I will update my drawing again in the morning

I was thinking today it would be great to see a current photo

Simon.
I believe the connection rods were supported only in the upper upper part to the floorplates which as not a very stable support and could create a bend, of course depthcharging could make it worse.

Valvespindle.
I guess we are talking about different spindle. What I mean is the spindle tap coming out of the valvehousing. May be it should be about 70-80 mm.

I guess a part of the confusion is that on the top of the valvehousing it is a small casing for the spindle stuffingbox having a yoke which is pressing the packing down in the housing by two nuts and the spindle is some 70mm above that stuffingbox before connecting to the universal coupling.

Tore, how does this look like now?

[NZSnowman]

Tore, do you know if the wooden deck on KNM Kaura was replace ? Or was it the original German decking.

Simon this will do ok!

Simon.
I guess some of the deck was partly renewed, particulary in the area of the wintergarden and the storage containers forward of the snortmast.

Hi Tore

Here a total realignment of the piping of the Fuel oil compensating system. Now to start on the piping inside the engine room
