Here is a photo of the doors for the main superstructure, made out of a thin piece of Oak with a surround made from plasticard, brass portholes and dolls house knobs. The watertight doors made from plasticard and the hinges also made from plasticrd with the aid of a magnifying glass 😁 I bought the two sets of portholes from MMModels as it wasn't worth the trouble of making them all, lazy I know 😜
Dumas kit Carol Moran, renamed Michael for my first grandson.My first build, learning how to make those brass railings each post being soldered following a paper pattern. Some customizing at the request of my grandson with added port holes, and deck features. He helped to paint it.
[Score: 10/10] 40" Enterprise Capable of 8mph and a runtime of 120mins Direct Drive to a Mother nature Controlled Through Acoms ESC - Comments: I love this 8 meter yacht,sail number K91 It has a great keel shape allowing weed to be ignored most of the time. Built by the southwater dabblers a while back and has been through a few owners before I brought her. Moves in the lightest of winds and copes with large gusts too. Am improvement on the basic model is the larger rudder allowing superb control (unless I get distracted!) Deck is lined in wood with a cabin top allowing access to the inner workings. I am running it on a acoms 27Mhz set as it has never let me down I can see little point in changing it to 2.4 Ghz The only thing I have done is added some portholes and a wheel to make it more realistic. As can be seen in last photo not all weed can be ignored!!!
I said on post until the plating finished. Well finished one side, just three more on the other. Drilling the portholes with a cone drill. Holding with grips don't want to cut my fingers. Sized to fit brass tube, (chromed will skim off) That will be the surrounds, fitted after finished painting the hull.
Finished the major parts of the hull and am satisfied with the results. Now turned to the superstructure, which has turned into a challenge in its own right. Decided to break the structure down into decks and concentrate on each deck individually; before “rolling them up” into the complete structure. Also decided to make the central “core” first and complete, before adding the curved frontispiece containing the forward bulwarks. This would allow all the detail between the two such as windows, doors and portholes to be accurately made and positioned. The structure from the first deck upwards was made removable to gain access to the internal systems of this working model. The lovely flowing curves, which attracted me to the vessel initially, proved a pain to reproduce. The bends around the front corners required making each deck front separately and then gently bending heated styrene around a former to reproduce. There is much opportunity for hurling! Added a L shaped strip around the front of each deck, so there is something firm to glue the front bulwarks to. Was concerned that without something like that the individual deck shields would never line up properly. Similarly added styrene U channel along the deck edges to give a surface to which the shield side rails could be fitted. This also replicates the vertical deck edge panels that are evident in pictures. Felt this would also make the structure more robust, enabling it to be removed and refitted without damage.
Started to add the finishing touches to the hull; portholes, a bulwark capping strip and bilge keels. The portholes were drilled to the outside diameter on the drawing and small sections of styrene tube epoxied in. These were then drilled out and smoothed to the hull contour. Once the hull is painted lenses will be added usimg clear epoxy. The bulwark capping strip is a small styrene “U” section CA glued along the top of the bulwarks. This tidies up the edge and gives a smooth, consistent appearance. Have never been satisfied with previous attempts at bilge keels. Tried making them from both styrene and wood, pinned and epoxied into place. Not very robust, although they looked fine. Plenty of scope for repairs! Decided to try another approach on this model. Purchased strips of 1/4” L shaped styrene and CA glued them into position on the underside of the hull, with the leg facing in towards the keel. Filled the gaps on both sides of the styrene with fibre-glass resin and then rubbed them down, feathering the edges of the bilge keel into the hull. These bilge keels are nice and strong and, from the outside, the bodge is not visible. It can been just seen from the underside if the model ever gets inverted. Hope that is unlikely though! From here on the construction will follow well established principles, so will only write bog updates as significant milestones are achieved.
As the under deck access was now as good as it would ever be, it seem be an opportune time to add the major pieces of operating equipment. One item overlooked in my previous blog was the stern bulwarks. The attached picture reminded me that I had recessed the bulwarks to epoxy a piece of alloy strip onto them. This was another attempt to make sure the bulwark joints were strong enough so they would never pull apart. The alloy strip had been bent to follow the correct profile, which was thus imparted to the bulwarks. The rudder post had been fitted earlier and the rudder horn now installed. The servo location was chosen to fit it close to the rudder. Appreciate the rudder/servo sense is reversed, but this reflects all my models and retains Tx control consistency. Linking them was easy through the generous holes previously cut in the bulkheads. An auxiliary bulkhead was cut and installed to hold the motor. Once the correct spacing and location was achieved, this bulkhead was also epoxied into place. Readers might question my choice of “O” ring and pulley drive. Have used this arrangement on several models and have never had a problem. The “O” rings easily last a couple of seasons, but usually replaced as part of the winter PM program. The arrangement has advantages in that the motor orientation can be reversed to minimize space and alignment requirements are reduced. It is also quiet, easy to work on and a modicum of speed adjustment can be made with the pulley sizes. The black tube in the foreground, looped out of the way, is the shaft oiler feed. Seems to have become is increasingly difficult to buy new shafts with this feature. Not sure just how well they work as always pack the shafts with oil and grease annually, but they do appeal to my Engineering sensibilities. The ESC and will be added Rx later, they will easily fit easily into the remaining space.
Hi Bellman My Club sail several similar boats as well as an Ibex. They are all fitted with detachable keels which are fitted prior to sailing but can be removed for transportation and display. Our sailing waters are large and exposed and without the keels the models would not be able to be sailed. On the water the keels can not be seen. I tried a long keel on my Cariad and it was not a success as the keel tended to keep the model in a straight line. I now use a detachable bulb keel. The amount of lead will depend on your model and its overall weight. The bulb keels are a fibreglass moulding that we fill with lead to bring the model to waterline after inserting fore and aft threaded rod into the bulb. You will need to have holes in the keel to let the rods thro and long enough to be above the waterline. I fit a plastic tube and wood support inside. A washer and nut hold the keel in place. Before filling with Resin weigh the resin in the tin and remove that amount of lead from the bulb. Once set I use silicon to make a good seal between the bulb and hull and which remains attached to the bulb. Attached are pics of my Cariad.
Recently visited the U.K and collected the hull from a relative. It is now back in Canada so a detailed examination can be carried out. First impressions are: 1) The Deans Velarde hull bulwarks have fortunately not been trimmed to the final dimensions, these are marked in pencil. The excess material will really help as the Teakwood forecastle extends further sternwards and this extra material avoids having to build the forward bulwarks up. 2) The hull has many details added to facilitate positioning; portholes, rubbing strakes etc. These will all have to be sanded off as they do not fit the Teakwood. 3) The Velarde has a pronounced “dodger” on top of the bulwarks around the bow. This will also have to be removed. 4) The bow leading edge is quite bluff, possibly to suite the GF manufacturing process. This will probably work in my favour as it can be extended forward and slimmed into the Teakwood style entry, which is sharper and more vertical. 5) The hull is slightly oversize (about .300”) , not enough to be concerned about, but it does make the revised LBP correct! 6) The hull is nicely made and a credit to Deans Marine. The initial plan was to modify the hull shape first to adapt it into the Teakwood. Decided, as it is quite flexible, it would be better to add a keel strip, bulkheads and deck supports first. It would then become rigid enough to work. This revision to my original thoughts proved the best approach. The hull needs several modifications, but until it is rigid it is premature to implement them. The modifications will only prove more difficult and then inaccurate. Made up a number of plywood bulkheads, based upon the MM Velarde plan, but reduced in height to suite the Teakwood. As these are trial fitted into place in the GF hull further adjustments can be made. Once satisfied with the bulkhead fit, they and the keel were epoxied into place. Horizontal stringers were also added to ensure the bulkheads were accurately positioned, vertical and not twisted until the epoxy set. Can probably remove them once the hull structure is compete, although they could also be left in place to support the deck. Will probably largely leave in place. Deck support stringers were also epoxied into place and the hull sides glued to them. The hull is now good and stiff and can be worked safely. As the stern portion will require further adjustment, the sides were left free from the stern bulkhead rearwards. This will allow the rework without cutting through recently fitted items.
Hi neil Good to see your are progressing. It's good to see that Paul has joined in the discussion and offered help.👍 He has a superb model at the larger scale and has been an avid supporter of Fireboats and the site since its inception. With this small model it is important to keep the weight to a minimum and whilst sealing holes with glue and filler is OK, I would go easy with soaking the wood in epoxy, it's heavy. Far better to cover with a sheet of tissue/glass cloth and apply a thin coat spread with a plastic (credit Card size) spatula to work well into the covering. It would be good to see a few pics of your whole model. Say two side views, a top view and a stern view. If you can weigh that would also be useful. Might help when you need further advice on the build Cheers Dave
Doug no nut and bolt honest 😜😜 What is this fillet you and Dave talk about and how is it achieved as I presume its easier than fitting the support and drilling more holes in the keel? Also now I've extended the hole I obviously exposed new wood do I need to apply sanding sealer before applying glue or just slap it one. Do the photos look OK to start gluing??
[Score: 5/10] 28"/4500g Graemsay Twin Propellors (3 Blade 40mm) Direct Drive to a Mtroniks 600 (3 Blade) Powered by Lead Acid (6v) 7Amp/h Batteries - Comments: I am about to start building this model of an existing Orkney Island ferry - due to be in service until 2025. Construction started, all port holes and windows cut out, deck access doors and rear ramp cut out. Running gear loosely fitted prior to alignment and epoxying in place. Photo is of the real vessel in its short form, it has now been lengthened by 4.5m.
