    πŸ“ Detailing continues RMS Olympic Bench seats
    8 years ago by Dave M ( Vice Admiral)
    Flag
    The poop deck, B deck and Boat deck contain bench seats. Of a typical Victorian design with scrolled Iron ends. I was fortunate to find a friend in Gordon Brooks who helped me prepare a CAD file which was submitted to an etching firm and gave me excellent results. I have added some benches but more need making. The Mahogany slats are made from some thin veneer cut into very thin strips then superglued to the etchings in a small jig. Another etching completes the bench by adding the central seat support.
    The end result looks OK but I would like to perfect a method of making the slats more to scale.
    As well as the bench ends the etching also includes many 5 bar stanchions as the scale link I originally used were only 3 rail.

    πŸ“ Detailing continues on RMS Olympic - Windows and Rigging
    8 years ago by Dave M ( Vice Admiral)

    View All
    The outside window detail was copied from the plans and transferred to overhead projector film and printed using a laser jet. Each window was cut just around the printed detail and fixed to the correct window using clear canopy glue. The water jet cut windows are consistent size so everything matched up perfectly. Took three days to print/ cut and fit all the windows.
    The catlines up the fore and aft masts were drafted onto a sheet of paper which was pasted to a piece of wood. Nails were used to secure the verticals and the horizontals were made by cutting slots in the wood and wrapping cotton into and round the wood. White canopy glue was used to paste all over having waxed the template to protect the jig. When dry I used a sharp knife to cut off the surplus leaving some nice relatively self supporting ratlines.
    As I sail the model rigging needs to be easily removable. For fore and aft running lines I attach small springs which clip to hoops at deck level. All other mast rigging is fixed to each mast and I have used small berylium (ex brushless motors) magnets superglued to the bulwarks. A small metal tab attached to each line can then be place over the appropriate magnet and adjusted to tension.
    The aerials run from fore to aft and I used shirring elastic as this keeps everything nice and tight and is self adjusting as the temperature and humidity changes.

    πŸ“ Detailing continues on RMS Olympic - Winches, Telegraphs etc

    View All
    I have continued to add more fixtures and fittings on an ad-hoc basis mainly due to other commitments but mainly due to a lack of space indoors to work on the assembled model. The recent spell of fine weather has allowed for several days of outside work so progress has been good.
    There are a number of winches and davits that needed to be made and fitted. I made some masters and cast with fastcast. The drums were turned from brass.
    The docking deck and wheelhouse contain telegraphs etc and these were made from turned brass rod. As before I made sufficient to supply the Olympic and Titanic.

    HI Bob
    OK. I don't have a detailed list of what we bought and we were making two models so I might be best advising the type of wood we used and leave the quantity required to yourself. you will need a good building board and we used 3/4" contiboard. As we built the hulls in two halves we used an 8'x4' sheet cut into 2' x 8'. The frames were from 3/8" exterior ply (Malaysan) and I believe we used 4 off 8' x 4' sheets so you will need two. We had the plans photocopied and used the cut up photocopies stuck to the wood as templates. This will result in lots of offcuts 9 from the centre of the formers) and you may prefer to use less wood by cutting the frames in half. We were working to a tight timescale and had other uses for the offcuts. Bill has extensive wood working machinery and wood so the stringers were cut from old pine floorboards and run through a thicknesser / planer to achieve a uniform 1/4" square (approx). From the build blog you will see that we made the hulls upside down on the boards so you need to provide support for each side of each former. The plans need extending to allow for the fore and aft rake on the hull and we added about an inch peg at the side of each former to allow access whilst building. The planking was cyanoed with balsa 1/8" x 4' cut into smaller strips to accomodate the curvature. Once planked the hulls were fibreglassed inside. We used brass square section to support the rudder which was brass sheet with a stainless steel shaft. The prop tubes and shafts were made with stuffing boxes and the props from turned brass and soldered blades.
    The decks and superstructure is again ply and we had the deck houses waterjet cut from thin ply by Steve Tranter. He hopefully still has the file so could cut you some. Delivery to Canada may be a bit costly though.
    Motors were from Model Motors Direct in the UK. We have used 3 off 555 with Mtroniks ESC's 15amp. I have found that weeds in our lake can cause the motors to get quite hot on a long sailing session and I may need to either put geared drives 2:1 or water cool the motors. We use removeable lead for ballast 50kg plus a large 12v 18Ahr SLA (20kg) so the hulls are in the water before we add the ballast.
    You can print out our build blog and lots more detail will be found. We cast many of the fittings from our own originals using silicon moulds and fast cast resin.
    I suggest you get the plans and after studying them work out how you wish to proceed regarding wood and quantity etc.
    Hope this helps
    Perhaps a pm may be more helpful as you may have particular questions that require quite lengthy answers.
    Good luck
    Dave πŸ˜€

    HI Dave,

    Yes, I would prefer plank on frame at 1:100 scale. I know the larger the scale, the more detailed it can get. Also, can you recommend motors, props, speed controls and suppliers of these items? Any help would be greatly appreciated.

    Thanks Again,

    Bob

    Thank you for your comments. Both the Titanic and Olympic models were scratch built by Bill Lucy and myself from Robert Hahn Titanic CAD Plans http://titanic-model.com/hahn_plans.htm. Come on 6 sheets about 12' x 4'. They are CAD drawn plans and take a while to print so delivery is about 2 weeks . Not cheap but detail is mostly present. We also relied heavily on RMS Titanic a Modemakers Manual by Davies-Garner ISBN 978 1 84832 084 0. We also collected a library of Titanic related books many with photos to try and replicate the original. Many pics are of the Olympic but as the first of the class there were many similarities externally with one or two notable exceptions. if you do decide to build a model please feel free to send me a pm and I will share any info you require. πŸ˜€

    πŸ“ Railings commenced

    View All
    Work continues with fitting out the details. There is an abundance of railings all round the fore and aft decks together with rails round most of the structures on the boat deck. Bill favours making his own stanchions from litho cut and punched but I chose to use scale link etchings. We used fine musical wire for the railings superglued in place. Positions marked in pencil from the plan directly onto the deck edge. I used a 0.6mm drill in a small battery operated (Aldi) drill to make the holes for the stanchions, which were fixed with a dab of thick superglue. When all in place the thin wire was threaded through the holes and finally fixed with another dab of thin superglue to each wire/stanchion junction. Slow but satisfying work. Finally when all dry I applied an almost dry coat of white acrylic to the railings. This is work in progress and final finishing is required to straighten and Irregular runs and apply a final coat of paint before protecting with clear varnish. For consistency I will need to paint all the railings at the same time.

    πŸ“ Led light control
    9 years ago by Dave M ( Vice Admiral)
    Flag
    View All
    To control the LED's in the hull sides I have installed four LM317 voltage controllers, two for each side. This is necessary as I am using 5mm and 3mm ultra bright LED's and they have different current requirements. As we display often against a wall or background it is useful to be able to control which side is Illuminated and at the same time allow for both sides. This is achieved by using two two way switches, one to select a side and the other to select both sides. I set the LEDs up by adjusting a trim pot on each controller to give a good bright light of identical brightness on each side. I have restricted the controllers to give a variable voltage up to the max allowed for the LEDs.
    The supply to both controllers is fed from the main battery via a remote LED dimmer duly fused. This works brilliantly as the lights can be controlled remotely and dimmed to suit the ambient light level.
    The current per side varies from about 70Ma to 100Ma so full lights on both sides use 200 Ma at 12v Ie less than 3w.
    My main problem is shorts occuring in the hull wiring usually where the fore and aft decks are fitted. I have yet to find the best solution but have fitted 500Ma fuses in the feed to each set of lights so that I can resolve problems before fitting the superstructure. A LED across each fuse will light if the fuse is blown.
    The pictures show the rear control panel mounted above the motors.The LED dimmer is mounted underneath this panel. The three ESC's can be seen with the two LED control switches above the receiver. The 317IC circuit board can be seen below the croos deck former. The lights are connected between the hulls with some ribbon cable and a plug and socket.

    πŸ“ Ballast Carrying and superstructure box
    9 years ago by Dave M ( Vice Admiral)
    Flag
    View All
    Each model needs 50Kg of lead as well as the 20Kg battery. Not surprisingly this is not an easy task as the model need to be in the water before any ballast is loaded. My ballast is carried in two ply boxes with a dowel handle. I can carry one in each hand or put both on a wheeled trolley. The battery can also be carried or taken on the trolley. All the ballast is numbered to ensure it is fitted in the correct location.
    The superstructure is carried in a large ply box with lid. The main centre section fits along the base and the fore and aft decks are held attached to the sides of the box. A lid then closes the box and is held with two catches.
    I obtained some 1" flat luggage straps and adjustable fittings and these allow me to carry the box.

    No such luck with the carrying. Do have a two wheel pallet truck (Aldi's best) so not too bad. 😊 Plenty want to help assemble but unless they get it right I have to readjust everything. 😰 Quicker to just accept its heavy and take your time. Also lots of small bits so handling in correct manner is very Important.

    πŸ“ Olympic sails on the eve of the Titanic Centenary

    View All
    Replaced all motors with 555 Mk2 supplied by Alastair at Model Motors Direct. Control is now realistic and scale speed is easily achieved πŸ˜‰ .
    Titanic was due to sail today also but due to a technical fault ( Battery & Transmitter left at home 😰 ) this did not happen. it was on display though πŸ˜€ .
    Olympic still has much work to be undertaken but the lights are now fully functional on the hull and Titanic will be fully wired this week.Four independent 317 IC controllers are used to supply the 3mm and 5mm LEDS on each side. I can adjust the brightness to balance the 3mm with 5mm and bought a remote LED dimmer from Component Shop which feeds the four ICs allowing for fine control to suit the ambient light. This also has an on/off switch so no need to remove the top deck to make adjustments, For display purposes a 3 way switch allows port or starboard light to be selected and a further switch allows for all lights to be on. 😎

    πŸ“ Olympic Launched

    The arrival of BST also gave us a beautiful warm and calm day πŸ˜“ . Olympic, still in its unfinished state, was launched at about 1pm having taken on the 70kg of battery and lead ballast πŸ˜€ . The motors all worked and sailing for a short circuit took place. The transmitter was then fine tuned πŸ˜‰ to the model and I sailed around the lake until about 4.30pm. it is clear that the 777 motors and the small Buhler whilst having plenty of power, are not really suitable. 😟 The large coarse pitch props really need a nice low rev high tork motor. At one time this would have been the 555 πŸ˜€ sold by Model Motors direct but that supply has dried up. I'll be speaking the Alistair Graham tomorrow to see whats on offer.There was a very small amount of water in the rear hull. 😟 This has entered via the small portholes just above the waterline at the rear. I will have to fill these with some clear epoxy resin to seal. We did identify that this may happen plus the shaft stuffing boxes need packing as some weeping was evident. For a first run this was really good. πŸ˜€ The model looked superb on the water and the unfinished state is not obvious. Bill attended to help with the launch and being a nice day there were plenty of spectators. Fireboat attended with his dad Peter and sailed his superb Fireboat πŸ‘

    The ship looks great and is a great credit to you both in all your hard work, I hope I will be able to make it north one day to see them when they are finished.
    I am afraid that I have not done much with the Coromandel as I have been somewhat diverted by other things.
    However as I do not know what its original funnel colours were I shall do it like the White Star Line in memory of the Titanic. 😊

    HI Gregg
    Thanks for the info. Space is not really a problem.We need very low revving high tork motors and unfortunately most small brushed motors are not good at low revs. I have looked at the Westbourne offering but the revs are too high. if all else fails we may go for a Smiths motor used in the Morris Minor heater fan. πŸ˜€

    Westbourne model centre sell a 555 motor Dave, if thats what you really want, but suppose its all dependent on how much room you have. the 900 "style" motors I bought off ebay were a bargain priice and exactly same spec as the graupner ones, but for only AΒ£12 each, they give geat low rev/high torque output, as I fitted a pair in the mersey and its running 50mm 4 blade props, with only a 5000 mahr battery as gives me a running time of 40 mins, so on lead acids should still give hours of use.
