  1. Hi Terry,

    If you are going to install LED’s you have to do some homework before.  If you are going to install just a few LED’ say three lights is one thing but if you are going to install a substantial amount of LED’s, like I am doing about 75 LED’s is another story.  If you use a 9V battery you are limited to just  4 LED’s connected in series.  Another problem if you connect them in series is that if one LED fails all the others in the circuit will fail, and don’t forget that most probably the LED’s will be installed somewhere where you cannot reach to replace.

     

    With a parallel connection you can install as many LED’s as you like but you can never run them from a 9 volt battery as it only produces 400-500 milliampere-hour.  Normally an LED has a forward voltage of 2.2volts with a rated current of 20 mA,  75 LED's x 20 = 1,500 milliamps (1.5 amps).  So the supply has to be able to at least produce 1.5amps.

     

    In my case I am using a 12 volt, 4.2amp transformer which I already had.  This is more than enough.  A 12 volt, 2 amp transformer would have done the job as well. With a parallel circuit you are going to have twelve volts on each LED which will burn it out immediately as too much current will flow in it. So with every LED you have to connect in series a resistor to lower the voltage supply to the LED to 2.2volts and the current flowing through it to more or less 20 milliamps.  Another advantage in connecting in parallel is that if one LED fails it will not affect the others at all, the rest will remain lit.

     

    I am not much of a teacher, there is a very good explanation in this forum itself and also explains how to calculate the value of the resistors required.

    Steve,

    Thank you for your comment.

  2. Hello there, my apologies for the long absence from this great forum.  Unfortunately I had to shelve the project for some time due to my work.  Last summer I was extremely busy and I was working very late in the evenings as well.  Now I basically settled down and I started on the Victory build again.  I have a lot of catching up to do, visiting your builds.  Hopefully coming summer will be more relaxing and have time for the build which I enjoy doing.

     

    Going forward I decided on the following hull finish

    ·         Upper part of the hull to be paint finished as per the instructions manual.

    ·         Lower part of the hull not to be covered with copper plates but leave with the second planking timber finish. 

    ·         Use the same walnut strips supplied with the kit cut into 85mm lengths to represent 20ft planks and use the four butt shift system.  I will take Heinz’s idea of leaving a very small gap between the planks and use black filler.  This will enhance the outline of each plank.

     

    So here goes my update for my last slow progress:

     

    Lined the side doors.

    Marked the positions of the lower and middle wales and planned the positions of the planks.   From the lower edge of the lower wale to the keel I divided into bands.  I made this with string by measuring the widest part of the hull and divided in 25mm bands (5 planks x 5mm), making sure nowhere else is wider then 25mm or narrower than 12.5mm (half the total of 5 planks).  If everything goes according to plan there should be no stealers.   Took me quite some time to plan the bands.

    Marked the individual runs of the planks from the upper edge of the middle wale down to the lower edge of the lower wale.

    First rows of second planking.  You can see that some of the planks are not cut into 85mm lengths.  That is because they are going to be covered again with the wales.

  3. Not much to show.  Unfortunately I am not finding enough time as much as I would have liked to.  I finished planking the middle deck.  I used the four butt shift system.  There is a very good article in this forum's 'Ship Modelling Resources'.  The title is Simple Butt-Shift Deck Planking by Ulises Victoria.  For the plank edges I used a 6B pencil. I gave it two coats of matt varnish but was thinking of finishing it with a coat of satin matt varnish.

  4. Fitted part of the quarter galleries and their lights.

    Lights well hidden in the space between the  galleries.

    I try every light I fit to make sure the connections are ok.  After I fit the skins there is no way I could get to them again.

    Lights for the stern galleries.  Wiring still underway. I have also prepared the resistances for the three stern lanterns.  Very thin wires will be soldered to the small circuit boards and passed through very thin copper pipes to supply the power to the lights in the lanterns, HOPEFULLY!!!!

  5. Heinz,

    Thank you for your reply, very much appreciated.   I haven't started the second planking yet. Presently I am working on the quarter galleries and they are taking me more time than I thought as I am am fitting the lights in them and had to do quite a bit of thinking to avoid any wiring or lamps showing through the windows.  Will post some pictures when I have made some more progress.

     

    Robert

  6. Thank you all for your comments.  Sorry for not replying before but I have been very busy, in fact I don't really have anything new to post.  Before I start the second planking I have to assemble the quarter galleries, including the lights for them, so I have to do a bit of thinking how to wire them.

     

    Ray,

    Don't be discouraged and you don't really need that much tools.  There are some tools that although it is a help to have, but you can do without.  I found the Bluenose II very helpful to learn on and gain some experience,  mind you I still have a long way to go.  Some builds I see on this forum are really a piece of art.

     

    Heinz,

    I am impressed with YOUR work. As I am thinking of not coppering the hull I have been having a close look at your great hull planking.  Did you slightly bevel the edges of each individual plank to make them stand out more?

  7. First planking ready.  It wasn't easy, but I'm quite happy with the result.  I think I learned a few things as I went along, what I should and what I shouldn't do next time. Now I have to decide if I am to copper or not.  If not I have to be much more careful with the second planking.

     

    A few images of the first planking not yet sanded and finished.

  8. Ian, thank you for your reply. The wood supplied with the kit does not have that kind of problem. It seems to be all at an even smooth thickness. The only thing I can see is the different shades. I think I will have a go with it. Your finished hull looks fabulous. It did not take me much to convince myself how great the hull looks finished in wood after I saw your work.

    For now I am still trying to finish the first planking. I will post some images when ready.
