And hi to all once again.
When enlisted in the Spanish Navy Jorge Juan was fitted with a Mk.15 torpedo tubes set, the regular equipment in the US Navy at the time, but in the mid 60�s she her armament was upgraded with a double set of Mk.32 torpedo tubes, on both sides of the aft structure, that for a time coexisted with the Mk.15 tubes, what means that this ship mounted the surprising number of 11 tubes !!!! :
As the pic is not too clear, I compared it with her sister ship
Alcal� Galiano, to find the very same arrangement of tubes :
Even the ECM�s seem to be the same on both ships, as the Spanish Navy policy usually is, so we can definitely assume that both
Jorge Juan and
Alcal� Galiano had the same torpedo armament, before the Mk.15 tubes were removed in a later refit, probably at the beginning of the 1970�s.
Once this has been set, and for once, I found a very clear pic of these Mk.32 onboard
Jorge Juan herself, a rarity, as the tubes used to be wrapped in a dark grey canvas for protection :
This pic allows the tubes to be identified as this specific version, as Mk.32 tubes were modified and upgraded as time went by :
The width of the tubes was a kind of a problem, as the relationship length/width is very clear, but the width measures I found referred only to the caliber of the torpedo itself. This useful pic allows to find the correct width of the tube, comparing the outer circle and the inner caliber, and after a few quick calculation it allows to use a 3.2 mm. Evergreen tube without further problem. Great !!!.
The breech chamber of this torpedo tubes is semispherical, and can be done very easily carving and filing a piece of 2.0 mm. Evergreen rod, that has to be rolled back and forth afterwards under the X-acto until it detaches itself :
Once the breech chambers and the reinforcement rings were set in place, making the tampions was a pure game. I had to widen the caliber of the tubes with a 2.0 mm. drill, and then cut pieces of 2.0 Evergreen rod; I glued small pieces of 0.25x0.5 Evergreen strip on them, and cut the excess :
Then I simply pressed the tampions into position, and done. The cuts are so exact that the pieces do not move at all, and no further glue is needed. The effect, even at this scale, is superb :
To be continued, but as for now I hope you like it.
Best regards from Spain,
