    Hi Shipmates,
    Mini update, torpedoes in the tubes they are made 25mm diameter wooden balls. Top of torpedo tubes in the picture, glued in with super glue (the thin stuff) after sanding the entrance to the tube to get the position correct.
    roof top of the helm added detailed trim and skylight window (non-functional as there is a beam under it).

    Hi Peter,
    I have tried to keep the weight down to a minimum, as my back is in a poor way, so had to come up with ways to reduce mass without compromising the build.

    examples
    a/ Aluminium prop shafts
    b/ 0.8 mm ply (skins and deck)
    c/ rudders resin blades

    I think if one of your torpedoes hit the target, there would be no teeth left to clean. They look good though. Mine are solid wood on my PTB which we think is an Elco 80ft PTB.

    Hi Shipmates,
    Mini update, started building up torpedo tubes they are made from two 'Sterident' tubes that are under scale by a 1mm in diameter will build up paint layers on them! The total length of each torpedo tube is 30.5mm.
    Used rubber bands as joint rings, two more to be added to each torpedo tube.

    Hi Shipmates,
    Mini update, added some details:-
    1, Two strengthening bars diagonal from spray shields and a petrol filler centre (pic 4)
    2, Drip bars over windows, apart from starboard forward window. Not sure why this is missing,(please enlighten if you know) I think it may be due to the hatch above this window being hinged inboard, pt 103-127. perhaps could be an obstacle to exit? see picture from pt103.com. (pic 5)
    3, Small step to rear turret, and petrol filler. (pic 3)
    4, Brace on top part of roof. (pic 1)

    Hi Doug,
    Any Drawing would be of help, I have collected a few!
    The Serident tubes are under scale by a 1mm in diameter will haver to put plenty of paint on them!
    A picture of an Italeri 1/35 Scale Elco PT 109 Kit by Stuart Hurley also from the 103 web site, its a detail build of the 109, modified from original.

    http://www.pt103.com/Italeri_PT109_Build_Stuart_Hurley_3.htm...

    AFTER SOME RESEARCH OF ORIGINAL PHOTOS I THINK THE PT103 WEB SITE IS CORRECT SEE PIC 3 FROM THE FACTORY AND PIC 7 OF PT105.

    "the torpedo tubes are made from two 'Sterident' tubes"
    Now there's an idea!๐Ÿ˜€
    I use the German equivalent, Kukident๐Ÿ˜‰, have a small carton of 'em saved for ...!? The 'Sure they'll come in handy for something' principle๐Ÿ˜ Bit over scale for my 1/35er though๐Ÿค”
    Looking forward to your next instalment Roy๐Ÿ‘
    Cheers, Doug ๐Ÿ˜Ž
    BTW: attached a pic extracted from the US Bureau Of Ships plans of the PTB 103 class.
    Clearly shows that the day cabin forward window starboard side did have a rain/spray deflector fitted.
    Shown dotted as it's behind the torpedo tube.
    Only the windows at the forward and aft ends of the cabins seem to be without.
    I have more of these extracts and photos of the cockpit and other details (PT109) if you need them just YELL๐Ÿ˜‰
    PS: I know that pic you posted of 'PT103'.
    It comes from Jeff Davidson's excellent set of CGI pics from a 3D printer build, NOT from an original boat!
    A small boo boo there๐Ÿ˜‰

    Hi Doug,
    Thanks for the glue tip, if I have problems I will buy some.
    I have tried to keep the weight down to a minimum, as my back is in a poor way, so it hopefully will be between 5 and 8kg
    Example the torpedo tubes are made from two 'Sterident' tubes (denture cleaning tablets) I have only just started making them.
    When I get time I try to weight it.

    Thanks for that info Roy ๐Ÿ‘
    A lucky fit with the fish food lid๐Ÿ˜€
    I'll have to look for mini portions for my 35 scale gun tubs! Given me an idea though, shopping tomorrow๐Ÿ˜‰
    "The gun turret ring was a cut out of a fish food container, I have stuck it down with non expanding Gorilla glue, just hope it holds as the plastic is a bit flexible."
    I use Deluxe Materials R/C Modellers Canopy Glue for plastic to wood joints Roy.
    That's what it's designed for, probably originally for aircraft canopies.
    I bought it to fix the acrylic 'glass' windows in my Sea Scout. Worked great, dries crystal clear and don't shrink or expand๐Ÿ˜Š
    Like I told Marky; I don't let wild animals in the house, except maybe Gisela when I've exceeded my miniscule authority๐Ÿ˜ Joking aside; she's worth her weight in Lithium bless her!๐Ÿ˜

    Thanks for adding the tape measure๐Ÿ‘
    So that chunk is just over 1/4 of the whole beast๐Ÿ˜ฎ
    She's gonna be a behemoth, what do you estimate the final weight will be?
    Following with extreme interest.
    Cheers, Doug ๐Ÿ˜Ž

    Hi Martin,
    The Fish are Silver dollars (common name) 2x male 5-6in 2x female 3-4in, they are related to Piranha, but prefer vegetation (hence plastic plants) they are non aggressive, but are skittish and panicky.

    Hi Doug,
    The gun turret ring was a cut out of a fish food container, I have stuck it down with non expanding Gorilla glue, just hope it holds as the plastic is a bit flexible.
    Added a measuring tape, so you can judge scale.
    The turrets were a plumbers joint for 60mm pipe, I think?

    Nice neat job Roy๐Ÿ‘
    Excellent work,
    Very shipshape and 'Bayonne' fashion!
    What did you make the gun tub ring from? Some kind of jar top?
    That is something I still have to do on my 1:35 version.
    She is developing into one nice 'beast'๐Ÿ˜‰
    At 1:20 she must be a Four Footer๐Ÿ˜ฎ
    Would be nice to see a 'stick of inches' in the photos.
    Keep it up,
    Cheers, Doug ๐Ÿ˜Ž

    Hi Shipmates,
    Sorry have done little to the boat in the last 2 months have been concentrating on me Batboat https://model-boats.com/blogs/79067#85538

    Added a 2mm wide strip of wood (mahogany) around the cabin between roof and sides.
    Built up 4 vents from fittings and styrene tube, added a washer to the base and some shrink down around the join, then added a 5th fitting to the cabin top.

    Started work on the Helm.
    Finding this part difficult, as using various sources of information.
    Have made some major mistakes with the build but building from scratch has its pitfalls. I will not list them, as I find it depressing.
    I have had an idea of putting servos in the turrets so the guns can move around but that will be done a lot later.

    As you say CB90 part of the fun of scratch building, I have even been known to make the same part five times until i got it looking how i wanted it.

    So keep at it, you are doing a great job.

    Hi There Shipmates,
    Have added the large Engine hatch to the back of the Dayroom cabin, so that the two act as the main access to the boats hardware.
    Also started on the Dayroom's Turret made from a 60mm pipe joint,
    after marking position, I cut away the corner of the Dayroom and glued in position.

    Still cannot get the hang of uploading pictures in the right order.

    Hi GC Ladd,
    I'm glad you are now inspired to finish your model, the things we do in life are often limited by 3 things, Time, Money and Motivation.
    It sounds like you have done a lot of work on the craft, you just got to bring it all together for the final push.

    Good Luck

    Nice build progress. I have a 1/24 scale Elco 80 footer (40" long) that I started many years ago from a modified fibreglass PT boat hull I bought from Dynamic Models, back in the late 80's . Every winter I tell myself "this is the winter that I will get this sucker painted", and after 10 years it has yet to happen. I have spent to many hours drawing and scratch building scale PT boat components with AutoCAD to just have them sit in a box waiting to be painted and mounted to the hull. You have inspired me to get my butt in gear and get this one finished.

    Spent some time on the day cabin sides, they are only 0.8mm ply so needed reinforcing, added start of roof camber.
