British T-class

[Kazzer]

Hello:)
This is my first post, so here goes.
My late father was one of the crew of HMS/M Truculent, She went down on the 12/01/1950, a total of 64 was lost along with 5 R.A.F crew, so you see I have an interest in "T" class boats.

Was your dad on the boat when it went down? Where was she operating out of? I think my dad was on her for a short while, or at least working on her from the depot ship.

Hi
Yes he was one of those that was lost, we have a service on the day every year in Chaterham,

She had just had a refit in Chaterham, and had been out on sea trails, the rest is history as they say.

I'm not sure which version of the 4" gun the Tally-ho had, mid war, but I think the Mark-XXIII would a good one to model. I also found some pictures of one that is in an outdoor museum somewhere, but some details I can't see, since it appears that some of it's parts are missing.

So Mike, if you can include copy of that drawing in my Order, at a reduced price of course ;), that would be great. I just don't want to pay a lot for it since I have much of the Info I need already.
Thanks,

Here's some pics of 4" gun I found. I think it's a mark-XXIII?
Sure are a Lot of Levers and Knobs on it. :(
Does this gun look like the drawings that you guys have?
If so, is anything missing from this one?

Mike,
* Is the 4" gun pictured above the same as drawings you have?

* What's the latest on getting the T-class drawing scaled?

Not trying to Rush you but........Well, I guess I Am. :D LOL :D
I'm very eager to get started on it! :)
Thanks,

Here is some more information on the guns

http://en.wikipedia.org/wiki/QF_4_inch_naval_gun_Mk_IV,_XII,_XXII

Mk XII gun on HMS Thorough, 1954


The Mk XII variant was developed for arming submarines from 1918, Mk XXII was developed to arm submarines during World War II. These submarine guns fired a heavier 35-pound projectile from late 1944[1]. Mk XII and XXII equipped :

• L class
• Odin ("O") class
• Parthian ("P") class
• River (or Thames) class
• Grampus (or Porpoise) class
• Triton ("T") class
• S class
• Some of the Amphion ("A" or Acheron) class

And more 4" guns - HMS Thrasher

I've looked at Lambert's Plan of the XXII gun and it is so detailed that I don't think it will be much use. I'm not sure what the front shield looked like on Totem, and that, and the barrel will probably be the main consideration when making a gun.

Yes, I'm not sure what the large tank is for (above barrel) on the mark-XXIII, but it's certainly Not on most T-class guns? The Tally-ho didn't have a shield over gun, most of them did not.
I think I have enough Info to build it now. :)
Thanks for pictures and links,

Anyone else notice how Mike keeps avoiding my questions about when my order will be ready? Should I start worrying again??? :confused: :D LOL :D

More pics of 4" mark-XXII Gun:
I think this is the 1939 design, without bell shaped muzzle (on end of barrel).
Note, last one has vision-blocking shield.

That's because I seldom go in to the office. I'll see what's what tomorrow.

I received the book 'The Hunting Submarine' by Ian Trenowden, that I ordered from a military book store in Australia.
It has a few pictures of the HMS Tally-Ho that I've not seen before, one of which is a very good shot of the deck, that will be helpfull for painting info. She was painted in an interesting 2-tone pattern (very dark and very light), different than most T-class subs.
Of course those colors could have been Pink and Dark-Red, for all I Know! :D
There is a great deal of Info about her missions and crew, which will be fun to read. :)
It shows a different Badge-crest than one shown on the submarine website. Of a Sea-horse not a Fox. It seems that a Fox would have been better, but now I'm not sure which is correct?

I designed a 'Completely Different' Bow-plane Retract system using only ball-joint pivots, bell-crank levers and push-pull rods.
I won't know for sure that it will work untill I try it, since hole clearances in levers are going to be critical to let them retract as well as pivot up/down.
I think I'll need to try something simple, since I probably won't have enough room for a geared retract along with the torpedo launchers in the bow.
But that is a large model, I may find that there is enough space, when I get the hull.
I was told that it was on the Truck, heading my way. :)

I'm thinking about adding another small WTC to the bow end of the 3.5" SD, (since it doesn't have one there already), Not for battery but for bow dive-plane-retract and activate servos, and the torpedo-release servos. Then run the linkage-rods thru the forward bulkhead, instead of trying to route rods all the way from aft end.
Probably 4 servos total in forward WTC.
I'll put a separate 5.volt regulator in it also, so those servos will not be powered from the speed-control circuit, since I'll be using high-torque servos there to pull the triggers. :)
It's going to be crowded enough without those at aft end also.:D
Getting the servo wires from aft WTC to forward WTC, the best way, is what I have Not desided yet? There are several ways but none of them are real easy and perfect. :rolleyes:
There will only be one signal-wire per servo which will only require a small hole in bottom of each WTC, so maybe it would be best to run them external with RTV at holes?

This is the Heavy-duty type coupler that I like for 3/16" and larger prop shafts. It has the quiet and smooth operation of a rubber coupler and splined connections for no slip at high torque. It will handle high-torque high speed reversals that some couplers won't. Robbe #1446, but I found a batch of an industrial version of the same thing at a much lower price.
This is what I'll be using in the T-class and Nautilus projects.
