    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?

    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 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?

    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.

    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,

    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.

    Here is some more information on the guns





    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 :

    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'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?

    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,

    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.

    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.

    Thanks,



    That would be Great! :)
    Do you have a Paypal account? I'd be glad to send any S&H required. If not, we can make other arrangments? Can you send it by email attachment?
    I found a drawing of 4" gun, on internet, but it only has left side view. :(

    Maybe I should find out what Mike Caswell has for me first tho. ;)

    Lets not forget that John Lambert makes a living from these plans, I do have a copy of his guns drawings, but I am trying to work out a small royalty deal if I run a copy. To date, I've not found any interest in the plans and it hasn't been something I needed to do so I've not pressed John.

    The plans I have --

    4"gun QF Mark XXIII on 4" S2 Mounting
    4.7" gun QFSA 40 calibre gun on CP Mark XV mounting 1930
    The latter was fitted to HMS Thames & Porpoise & Some Parthian and Rainbow class boats.

    Lambert has a few other plans see www.lambert-plans.com

    1 sheet subject = £10.50 and he takes Paypal.
