    HMS Unicorn. A display model.
    This is a display model. Bought on ebay as a partial build (hull). Finish the hull, eg stern lights, cannons, etc. Fitted the rigging, blocks and ropes. The standing rigging have over 1000 clove hitches. The rigging took weeks, and i now understand the saying "getting to know the ropes" I did not make a build blog as it would be very boring due to the build pace.

    Hi
    Wow, you have a lot of battery options.
    What I would do is decide on your battery option.
    Then fit a motor and esc to suit this.
    Then arrange the leds to suit that.
    Can you detail what you have with regards to the boat. Are you building it or is it already built?

    Hi, I am a bit confused. On your original inquiry you mentioned a 12volt battery.
    Now six volts then 7.2volts.
    You will need a different dropping resistor for each voltage.
    A 12volt led may work on 7.2volt but would be dim.
    You mention flickering when the motor is running. I have not found this to be an issue are the leds power should be directly to the battery via a fuse so any voltage changes on the battery should be minimal.
    All I can suggest is that you have to experiment a bit.
    Another solution it to use wheat grain bulbs to the correct voltage. This removes the need for resistors.
    Regards

    ๐Ÿ“ Wiring led
    17 days ago by Hillro ( Sub-Lieutenant)
    Flag
    Hi,
    The first thing to understand is that different colours require different voltages eg white =3 volts red = 1.5 volts.
    So using a 12 volts dc battery you will need to included a resistor to drop the voltage to suit the led being used.
    There is a lot of info on the Internet on how to calculate resistance value.
    With reference in how to wire them, just wire them in parallel in groups that you want to switch. Supplied from the battery via a fuse.

    With reference to general lighting on the boat you could wire 4 white leds in series , this would remove the need for resistors. This works by dropping 3 volts across each leds.
    Note leds are polarity sensitive so make sure they are connected correctly.

    There is lots of info on the Internet,
    Some model boat shops sites have the info you require.
    Get back to me if you need more assistance
    Robert.

    Thanks for your post very interesting.
    I was surprised that you have not fitted a plywood sub deck. This helps to keep the boat watertight and allows for inaccuracies in the planking.
    As you said in your post there are loads of ways to plank a boat.

    Decided to make the boiler room access so I could see how to make an removal access into the Hull.
    This was made from scrap bits of birch ply.
    The larger one was made first, but having a look at pics of the ship, online I could see it was the wrong scale.
    So I made another at a smaller scale.
    Happy with it now have to have a look for suitable pipe to make a funnel.

    ๐Ÿ“ Steering, etc
    2 months ago by Hillro ( Sub-Lieutenant)
    Flag
    View All
    After a few different ideas for how to fit the steering servo, settled on the method in the photo. Also coated the inside of the Hull with fibre glass resin.
    This helps with waterproofing and also strengths the Hull.
    I am now going to glue in the lower Hull some lead ballast using sheet lead.
    I intend to use sails to drive the boat but I am fitting a motor as a backup. I am using a belt drive, but may upgrade to a toothed belt drive.
    I am doing this to keep the motor well into the stern thus keeping the main Hull clear for the sail control.
    I have found info in the model boats mag how to do this using servos fitted with sail arms. Need to do a bit more research and head scratching how and where to fit the servos.

    I fitted a board in the bottom , inside of the bulwarks, inside which will be mounted the deck. The bulwark inside was painted white and on it glued prepainted black uprights. I then sanded the bulwark sides down to the top of the uprights. Mahogany hand rail is pinned and glued to the top of the bulwark. A shaped handrail for the stern.
    Now need to tidy up with a bit of sanding, etc.

    3 months ago by Hillro ( Sub-Lieutenant)

    Hi, if you are confident that true alignment has been achieved, a solid connection would be OK.

    However I would suggest some type of coupling to compensate for any misalignment.
    Vibration and heat generation from friction are usually clues on misalignment.
    Best of luck.

    ๐Ÿ“ Hull progress
    3 months ago by Hillro ( Sub-Lieutenant)

    View All
    Having looked at photos of the ship , I realised that the bulwarks need to be higher. So I raised this by one plank.
    This was just glued to the top of the bulwark using clamps to hold in place.
    Made and fitted the bowsprit, again looking at photos.
    The bow on the ship is reinforced using steel plates , thinking of using brass sheet and round head pins to simulate this.
    The prop and rudder has been fitted. This required me purchasing a long 6mm twist drill.
    I greased the shaft before fitting it as access is not possible after fitting the rudder assembly.
    Now looking into the motor. I found a couple of meccano pulleys to make a belt drive. Using these I can mount it closer to the stern allowing more room in the Hull for the sail control servos.
    I now intend to paint the inside using epoxy resin and secure some ballast lead sheet.

    ๐Ÿ“ Modified Stern, etc
    3 months ago by Hillro ( Sub-Lieutenant)
    Flag
    View All
    I cut off the stern at the last frame then carved another one out of lime wood, this time allowing room for the rudder arms ,etc.
    Filled in between the last few stern frames with car filler. This is to beef up the stern to allow the prop shaft hole without weakening the stern.
    To address the fitting of the deck I cut out the frames above the deck and fitting support for the deck edges.
    Fitted supports for the forward deck.
    I have researched what I need to fit under the deck.
    Motor with associated esc.
    Steering servo.
    Two sail control servos fitted with arms.
    Maybe a drum servo.
    And a battery.

    Hopefully being a sail driven model I will provide fixings for a removable drop keel.
    The major issue for me to sort out is access to the Hull when the deck is on and to remain watertight.
    Any ideas welcome.

    Hi, good advise has already been given however you have to fix your frames to a baseboard. This is to keep them in line and correctly spaced.
    There is a lot of examples on this site.
    I have included some pics of my current project.
    Do you have any info on what you are intending to build?

    I have noticed that the stern is not quite right. To get the rudder mounted in the correct location this needs to be modified. A bit of measuring and head scratching required.

    After a quick sand of the Hull to remove the obvious high point coated it with car filler. Once set, rubbed down to a smooth finish. Had to go over various low points with additional filler.
    When reasonable happy give the Hull a coat of undercoat to highlight the small imperfections that can be rectified.
    This sanding process is very dusty and some covid face masks came in very handy.๐Ÿคฃ

    You have not said what manufacturer is the esc. It sound to me that you need to tune either the esc or the zero point on your transmitter. The noise indicate that the esc is not quite at zero speed.

    I am going to fit a drive motor, can't afford a steam plant.
    It's interesting that the ship had a method of lifting the prop on board to reduce drag while under sail or in the ice.
    I still have to find out how this is possible. Not that I intend to do this on the model.
    I believe the rudder could be lifted on board as well.
    Sails were used because Discovery could not carry enough coal, and there was not any refuelling provisions.

    I am a great believer of using salvaged wood where possible.
    I started using mahogany planks but found it too stiff without steaming or soaking. So I changed to parana pine (an staircase handrail) this bent more easily.
    I was not too worried about the finish as I intend to fill with car body filler and maybe a glass top coat.
    I found some errors with a couple of frames which needed packing strips.
    The bow and stern were blocked out with lime wood blocks.
    The Hull needs tidied up in a few areas.
    Work in progress.

    Started a new project, a scratch build of RRS Discovery.
    The actual ship is in Dundee which is not far from me, so getting details from the ship is a bonus.
    I located drawings for a steam whaler which the ship was derived from.
    I decided to build it upside down. The frame profiles were cut out of 4mm birch ply using enlarged prints of the profiles, stuck to the ply and cut out using a scroll saw. They were then screwed to the base board.
    Next step is start the Hull planking.

    Is there any build blogs that show how to control a square rigged boat using radio control.
    I have plans of a whaling ship which is very similar rig to the RRS discovery.
    Luckily I can visit the ship in Dundee to get details of the rigging, etc.
    I have a book on controlling this type of rigging but it seems very complicated.
    Any help and advice welcome.

    First, what is your supply voltage.
    Leds the colour of the led determines it's driving voltage.
    White led requires 3 volts to light it.
    If you have a 6volt dc supply , you can connect two in series which gives three volts across
    There is quite a lot info on the Web about this and the use of resistors to drop the voltage required by the led.
    It's using ohms law to calculate the resistor size but you need the find the spec for the led.
    Led are polarity sensitive as well.

    Nice to hear from you. I am glad you are OK.
    The UK has only insisted that care workers have to be vaccinated, it a bit of a problem due to the shortage of staff (100,000) .
    There are shortage of staff in loads of areas.
    I think the lockdown has made a lot of people rethink their futures.
    Eg Why sit in a lorry 12hours a day. Commute to work 2 to 3 hrs every day.
    Being retired and looking back to working life, I tended to stick to jobs I was happy in, but when situations force a change, you find a different working world you would never thought of.
    It's very interesting that NZ has introduce compulsory vaccination for teachers, etc.
    Here they think the vaccination protection is weakening and boosters are required.
    Here they keep referring to Israel who are ahead of us. Their infections and hospital admissions are rising.
    I had a moderna as a booster. Felt a bit rough for a few days but OK now.
    Here, Autumn has started, trees are dropping leaves, and weather cold and wet. Darker in the morning but clocks change at end of the month.

    How is it going in NZ.
    I see on the news your lockdown has been extended.
    Just had my flu jab and a covid booster.
    Infections have be dropping here but for the last week have stabilised.
    Hospital figures are still dropping but they are delayed by a few weeks following the infection rate.
    Unfortunately my son's family have just caught it, He is fine but his wife and two children have tested positive.
    They have been isolating but are on the mend.
    In England, Infections are still rising, over 45,000/day.
    Cannot explain why Scotland Infections profile is different from England.
    We do still have mitigation in place like mask wearing, hand washing, and vacine passport to attend nightclubs, football matches, etc.
    Take care

    Hi, we over 50, are getting the flu vaccine.
    The programme has already started but we have to go to vaccination centres this time. Gp practices used to do it.
    We are also going to get covis booster shots 3 months after the last one.
    Children over 12 are now getting one jab of the vaccine.
    I believe with the flu vaccine contents is its a bit of a guess as the flu here has almost disappeared.
    The issues here now is lack of labour to fill the vacancies. This country has been running for years on the back of cheap labour from abroad ie Eu.
    We are short, in all areas, this could eventually be a positive thing as wages are rising. The business community is starting to realise that they have not been training locals and the UK government is not allowing recruitment from abroad.
    Believe or not they have allowed visas for 5500 poultry worker, ie butchers.
    Farmers now offering ยฃ35/hour to pick broccoli, etc.
    Short of 100 000 heavy goods drivers as well.
    All predicted, but seems to be a big surprise to the UK government.
    Latest is panic buying of fuel.
    It just goes on and on.
