Tores mailbox VIIC and VIIC/41 operation and technical details

[tore]

Hi Simon.
It seams to be very good. Seeing the hatch I just came to remember an intricate system of rods connecting the steelhatches to the wooden deck hatches so they could be opened in one operation. Anyhow this system was used for the galley hatch and fwd torpedo loadinghatch which were crewaccesses while alongside. Pictures below, on one of the photos you can see a guy operating one of the external valves from the deck by the T bar.

If you mean the enginedriven fueloil boosterpump which is fed from the overhead daytank remember the fueloil system sketch is showing the MAN execution and the GW layout has the fuel boosterpump forward as previously discussed. The suction line from the daytank is the dominant black pipe going along the side of the engine and is not shown on the sketch. The pipe you refer to (violet arrow) is the enginetop drain pipe and is almost hidden going along the engine at the level where the cylindercovers meets the cylinderblock.See pictures below.

I`m not sure if everything is quite clear so here is an additional sketch which I hope might make it a bit more understandable.

I just noticed somehow in the reference to the photo the U number is missing. The photo is from the engine room of U 178 just for the record as appropriate for all scientific papers .

The other day when updating the Camshaft covers I had to used the side view to make sure I had the correct alignment. So I update a little more of my side view

Simon.
It might be two drainpipes to the draintank, fwd and aft. I don`t have a proper photo to ascertain the lay out.

Beautiful Xmas decoration.   Have you noticed that only the centercover has 3 nuts whereas the 2 others have 4 ? I guess you had the correct configuration on the old drawing.
