  1. I had no idea that the entire book was available in digital form for free. That means that you can just print out the pages you need and enlarge them to the size you want. Now all you need to do is decide if you want a 3 island Farris style design or a single aft Dougherty style steamer. You now have all you need for either.

     

    Thanks for the links I will add them to my stuff as well.

    as a layman I have no idea what's really in there! I've been making no progress on it for over a week,

    I brought it up before in my last post but it seems I forgot to supply the title or link. I have this book and for all intents it is a step-by-step guide on building a tramp steamer of the turn of the century. 

    https://www.amazon.com/practical-fundamental-principles-described-especially/dp/9353863198

    It is available in a number of editions and prices.  There is no way you could use everything included in the book as it is intended as a reference for building the real ship. I would recommend  it to anyone building this kind of ship whether it be to house King Kong or not.

     

    Here is another source covering much of the material from the book but in less detail. You can click on the pictures and see details of much of what you are looking for.

    At the bottom of the article there is also some general arrangement detail on the Dougherty style steamer, also from WWI but more like what you are looking for. There are also a few other general arrangement plans available at the bottom as well.

     

    In addition since it appears that you have some 3D skills:

  3. All of the above methods are viable and have been used. I have used several of them including the moveable lid ballast tank I described above. When the "free floating" lid is is dropped to the level of the water and locked then the "tank" becomes a solid weight were the medium no longer moves thus becoming a solid weight. My method of locking the floating lid was to use two threaded rods that lay across the top of the lid and when it was resting on top of the correct amount of water, run the end out so that it locked the lid and prevented sloshing about and go ahead for the day. As the weight of water is a well known factor and the cubic inches of the ballast tanks can be deduced then it is easy to tell just how much weight would be needed for a given depth. I prefer to just stay with using water as it does not normally have to be transported to the running area and back. I have used this method in two barges that I used along with my RC tugs years ago. That way I could adjust the weight of the barge to suit the power of the tug I was using and not make it so light that it was too easy to be a challenge. No additional baffles were needed as the tank tops themselves were adjustable. I have also seen submarine style ballast tanks used and of course solid weights they all have their pros and cons as well as limitations depending on the size of the model.  

     

    Richard is not building a barge and may never have the desire or need for variable displacement in which case it is also relatively easy to figure out the needed weight with mathematical formulas and build to suit.  I was just offering one possible solution. YMMV

  4. You might consider just adding a flat "top" or internal lid to the tanks that travels up and down with the level of the water while resting on the surface. This would prevent the water from sloshing around and the constant shifting of ballast as the ship rolls and pitches. Once you know the level of water needed for proper ballast then you can lock the lids in place and vent any excess through vents over the side to show that they are full. These same vents can be used to allow air back into the tanks when pumping dry for transport.

    I've been waiting to start on the brittle

    Nice of you to think of me and wait Edward. I'm afraid that my special stock does not arrive until the week after next when my wife returns with it from her trip with a girlfriend. :(

     

    Nice work Craig I have never seen the interior of a Lee and am learning as you progress.

    Although the Canadians used other names

    It would take me a name-by-name check but I think that those corvettes that were transferred from the RN to the RCN maintained heir flower names as Eyebright did. Those ships built in Canadian yards and went directly into the RCN had names of Canadian cities or possibly rivers in addition to flowers. I also may be wrong! (If you are in doubt check with my wife, she will confirm that I am.:(

  7. I have done this in the past.

     

    I run the lights in parallel so I can run as many lights as needed. (LED) I run one wire externally making it look like conduit by gluing it directly to the bulkhead. The other wire with the resisters runs inside parallel to the string of lights. this is very easy to install and maintain and I have used wire as small as 80 microns for six running lights on a WWII warship, and have not generated any heat in years of off and on running. There is no need to use insulated wire when run like this. If you ran surface mount resisters they could possibly be run externally as well and hidden behind the light fixtures, but to be honest I see little value in that. Dollhouse ribbon self adhesive wiring strips also work quite well but of course have to be installed internally or painted over externally and still don't look quite right.
