Hi Haverlock. That's not a bad idea, and they're only in Wapping so a visit isn't out of the question either (I'm in North West London). I've just sprayed the hull with grey primer, so it's time to make a decision 🤔 Good suggestion👍 Thanks. Rob.
As long as the coil toutches the motor you will be ok if it is NOT touching then simply start agaain as it will b a waste of time.............................................With regards to your painting question simplest way is to go to halfords and buy grey primer with is acrylic....if it is a wooden hull then you WILL NEED to use a coat of Halfords or Equivellent car laquer to seal the primer underneath ...rub down with 800 DRY then put your grey on top of it....reason for this is simple the primer is porous so you will need to stop water getting at the wood,if it is GRP then no need for this Dave
The white metal fittings supplied with the kit are somewhat lacking in detail and some are overweight to say the least. I decided to produce some life rings to my specification I had tried to find suitable replacements on the web without success. So how to produce the ring part. I first tried with plywood but the finish achievable was not acceptable (can be seen in the pictures) so I then decided to use Bamboo (Ikea phone stand) for those who have followed from the start the same material as the grating on the foam tanks. First I cut some rough circles out of 10mm bamboo sheet and drilled a 10mm hole so it can be mounted on a 10mm screw mandrel. This allows the piece to machined on one side and then reversed and machined on the other side. The tool I used was ground with a 22 mm radius to produce the shape on one side of the ring and then when reversed and machined again the tool actually “parts off” the ring on the inner diameter leaving the ring free on the now remaining peg, the finish on the bamboo was good enough without any further sanding. The next step was to put a slot in the OD at 90degree intervals to hold the “rope” in position while the rope is bound in four places. The easiest way was to make a jig to hold the ring and to keep the rope in place while it’s glued into ring, it can then be removed and bound in four places each turn being super glued to keep it in place. Next job is to give a coat of sanding sealer that stiffens the rope and seals the wood. The rings are theoretically held to the cabin roof with clamp type brackets so again to ensure consistency I machined a piece with a suitable profile. I then cut radial slices to create individual brackets. The rings will actually be fastened to the cabin roof with 2 x 8BA bolts this is to enable them to be removed for painting of both the ring and the roof. At a later painting stage, I will be giving them two coats of grey primer and three coats of white, then hand painting the rope loops with red paint. The finished rings are much lighter and hopefully look more realistic.
Evenin Neville, So far so good👍 If you are down to the primer you can start sanding. I started with 150 grit (80 on the cutter where there was 'inches' of filler!) and worked up (down?) to 600 grit Tamiya Sponges before priming. The primer doesn't react much to the heat as it's mostly fine chalk dust or similar. Glad the chisel 'trick' worked for you as well. Cheers, Doug 😎 Forgot to mention: before priming I applied two coats of EzeKote resin. Sanded that flat with 400 / 600 grit Tamiya sponges used wet. Then primed with grey primer filler. Pics show Sea Scout, Fish Cutter and PTB. The latter after EzeKoteing and the last with primer.
NPJ, Dust isn't a problem until you come to refinishing. Do it all outside. I always spray outside and still do it up wind. Sprayed cellulose grey primer on my Crash Tender on Saturday and primer and off white enamel on my Chris Craft yesterday in a breeze, so stood upwind of it and all was well. Also rubbed down cellulose sanding sealer, dry. Dust just blew away. There's always a way round stuff. Cheers, Martin
Unless described as flat, paint was more often a brighter satin than matt and rarely actual gloss. White will always have been an off white as the components of paints were such that it was not possible to get a really bright white. I know that for a fact as my grandad always made his own and until PEP in the mid 60s (Plastic Emulsion Paint) there was no such thing as brilliant or appliance white. Unfortunately getting an decent off white is not easy these days since Plastikote went acrylic and their previously excellent paints started eating themselves on recoating. I now use enamels exclusively. They are densely pigmented, flexible and modern enamels dry pretty quickly. I am using a black enamel primer on my Crash Tender, which I will then spray with black "gloss" from the same range, which, once thinned with white spirit, will dry a little less than glossy. I still don't have a matt brick red for the undersides, but it can be made matt-ish with a careful rub down with 1000 grit wet and dry used wet and soapy, but be careful not to sand through, so very lightly does it, even 1000 grit can cut well when new. Decks were said to be Cerrux Light Deck Grey, anti-slip, which means a textured surface. That would be darker looking due to the surface texture's way with the light. The cabin sides were described as "smooth", i.e. same as the decks but not anti-slip. The roofs? Well, on Vosper's drawing "white" is crossed through and "Grey" written in. But, some pics do look white, the best pics look darker by a whisker than the sides and the roofs are clearly textured as they show evidence, as do the decks, of filth which will sit in the texture. You choose. NOBODY has yet given us chapter and verse. The fact is, an already very handsome boat looks so very pretty with white roofs. But they too should be off white if you can get it! Good luck. Fittings, btw can be had from SLEC in Watton in white metal. Basically the old Yeoman fittings, masters now owned by IP Engineering who bought them to cast when they owned Vintage Model Boat Company. Now they've sold that to SLEC, but I don't think SLEC have white metal casting facilities, so probably cast by Ivor still. I have just had a set for my birthday and they're excellent. They do need careful cleaning up as in mould lines need to be filed/scraped/sanded to a decent finish and then given good primered surface. No hook though, but it does include nav and riding lights. This site also has masts for sale in plastic, but I made my own in brass as I will the hook and davit. I have also just had a set of crew figures cast from my patterns and they will be available soon...a driver(Helm), a boss with binoculars and a lazy slob laying around in the after cockpit. Needs a roll-up to finish his look. No idea of price yet as don't know how much rubber to mould or resin to cast for a set. Yes, 1/16th scale. All this to finish a model I had 55 years ago! But I reckon it deserves it. Martin
As promised (or threatened?😁) stage two of the hull work and thoughts on motorisation. The hull was sprayed with two coats of grey primer/filler. Pic1. As usual this showed up the remaining imperfections (pics 2 & 3), but I'm not going to worry about them until I've got prop shaft tube and rudder stock sorted out and permanently fitted 😉 After my attempts to make and thread a 3mm prop shaft went awry Martin (Westway the Mechanicals Master👍) stepped in and made me a decent one complete with a bushed stuffing tube 👍 Vielen Dank Meister😊 I did however manage to make a 4mm to 3mm reducer so that I could fit a Rabeosch 35mm prop as seen in pics 2 & 3. The tube and shaft from Martin, arrived Saturday an' he only made it on Monday😊, have been dry fitted so that I can start setting up the gears, necessary to bring the drive down to the prop shaft fitted very low down in the hull, and motor mount. Pic 4. Motorisation: (Remember folks - this kit was designed and built as a static model!) I want to use the old 1950s Taycol Target motor which my Dad originally fitted in the Sea Scout which I have renovated and upgraded to brushless. See Build blog 'Sea Scout - Jessica' Many of you will know that the Taycol motors were field coil motors, meaning that they have no permanent magnet around the rotor coil, and thus reversing the battery connections to the brushes had no effect on the direction of rotation, as this simply reversed the magnetic fields of both stator and rotor coils🤔 To counteract this so that the motor could be used in both forward and reverse with a conventional brushed ESC I modified the motor slightly (separated the two coils) and built a simple converter board to connect it to the ESC. Again see the Sea Scout blog for the details of the conversion. Basically; once the field coil and brush-gear (rotor coil) have been separated a simple diode bridge can be used to apply the output of the ESC to the motor. This enables the reversal of EITHER field OR rotor coil polarity, depending on how you connect the converter to the motor. Thus reversing the direction of rotation of the motor. Beneficial side effect is that the diodes also suppress the commutator sparking😊 In my case, with the Taycol Target, I also cleaned, flattened and polished the commutator. Thus significantly reducing the potential for spark generation in the first place! A peculiarity of the Taycol motors is that they all use metal brushes, pressed phosphor bronze strip, so they need oiling! DO NOT oil conventional brushed motors with carbon brushes unless the brushes are exchangeable or you want to have to buy a new motor!!!!! Pics 5 & 6 show the proposed position of the Taycol in Gina 2 and pic 7 the prototype converter board I knocked up to test the motor, together with a Graupner Navy V30R Marine Brushed ESC. Details and results in the Sea Scout blog, including video of the sparks and oscilloscope pics of the drive waveforms before and after conversion! The latter showing the spark suppression effect of the converter😊 Some samples attached - last 3 pics. Pic 8 pic shows a more compact version of the converter, one of a few types I'm doing for Martin's various Taycols as a trade for the prop shaft he made for me and some useful material he sent. Thanks mate👍 Next steps will be 1) mounting the gears correctly on the shafts, requiring the manufacture of a 3/32" to 4mm adaptor and a 1/8" to 4mm adaptor, and keying them to the shafts - Hooray for mini milling machines 😉 2) manufacturing bushed end plates to hold the gears in place, 3) fitting the motor mounting platform. I'll probably borrow from my experiences of real shipbuilding and do this as a suspended 'false floor', i.e. mounted on stiff springs to enable adjustments to optimise the gearing mesh! On real naval ships this is done to improve shock resistance and to minimise engine noise / vibration conduction to the hull, thus significantly reducing the acoustic signature of the ship. Not that I'm tooo worried about being torpedoed 😁 Worth a try😉 Pic 9 shows the cleaned up and renovated Taycol Target motor. Pic 10 shows the drive waveform complete with sparks before modification.🤔 Pic 11 the cleaned 'forward' waveform with the converter board. Pic 12 the cleaned 'reverse' waveform, no suppression capacitors needed 😉 More soon folks, Cheers, Doug 😎 PS Along the way a new keel was fitted as can be seen in pics 1 to 3. The original builder had 'buried' the keel in the hull planking! 😲
Here's last night's first spray primer. I like this grey and will use it as the matt finish. Maybe then mask up and use the Baufix Grey for the cabin sides, with, OK, the Baufix white for the tops. I have black enamel primer for the hull and black enamel gloss. When you rub it down it's like soot! Martin
Well I'm blowed, Doug, your Dad must have known the same "bloke in the docks". But yellow? That was a luxury! Here's some more done on the Crash Tender. Excellent grey primer from the car paint shop. This weather has hardened it off to the point where it'll not only sand down but scrape too, which is a favourite method of mine. Must be the old clay modeller in me, eh? Cheers, Martin
Boaty, it's amazing how many people HAD Taycol motors, but don't anymore, apart from our chum Doug in Munich. And I'll pick his brains later maybe for info on controlling the Taycol Supermarine in the Crash Tender. Then again, I might just set it off on one pack for slowish and switch in another for faster. I ain't into reverse. Boats don't go backuds. I've had enough real ones to know that! Two of those didn't have any gears. One had a clutch and the other didn't even have that. It starts, it goes, quickish! Always had a paddle handy in the Albatross! I'm not really into the boat club festivals of steering round stuff or backing into docks, so why trouble myself with ESCs which seem to fail often still and weren't around when I had the boat originally. I have gel cells, but the damned things have all gone dead on me, so I might see about Nimh packs when the time comes. I went to get some one shot cellulose putty to fill the cracks and grain bits and the old nail head dips. But my favourite auto paint shop said they hadn't sold it in ages and offered me some acrylic crap in a tube. Not a bloody chance!!! "Gimme the thickest brushing primer you got and it better be cellulose". Yeah, got that, he said. "So why ain't you got stopper?" No answer. Anyway I get this stuff home and it's thick, cellulose (skin forming after 3 minutes) and bang on the right shade of light grey for a Crash Tender. I shall experiment with my Chinchila dust next for the non-slip areas and mix a pot of the primer with a bit of white to do the cabin sides, when I finish spray. For the moment, I very quickly slapped it on with a brush and will leave it for today to harden then start a very big, dusty, rub down session tomorrow. OK a litre of primer ain't cheap, but it's cheaper from a car paint suppliers and it's bang on colour. It'll also do a LOT of boats! I have a black primer in enamel for Vanity, which will also go on the sides of the Crash tender, followed by black gloss enamel, but's a way down the road yet. Talking of old stuff boaty, the white enamel my dad insisted on painting the boat back in the early 60s is hard as rock! He used to get it by the 20 gallon can from a "mate on the docks". We had docks in those days. Dad called it ship enamel. We all knew what he meant. Our entire house was shades of pastel tinted ship enamel! Tints courtesy of another mate on the docks. He had a lot of mates on the docks. It was difficult to be a Cockney family and not have mates on the docks! Pics later of the slapped on grey primer, which, I should say, argued a bit with the sanding sealer. Nuffin' a good rub down won't sort out. Martin
Evenin' George, any mid to dark green would do nicely. Suggest a satin / semi matt paint. Something like the Humbrol 131 or 195 in the attached chart. Of course it doesn't have to be the little Humbrol tins (unless you have an airbrush😉) but a similar colour in aerosol, maybe from Tamiya. Type depends on what was on it before!! To be on the safe side give it a couple of thin coats of grey primer first. Flat off with 600 wet & dry then apply the colour coats. E.g. acrylic. Where on earth, and when, can you sail up there in the frozen North!? 😲 Good luck, and have fun, cheers Doug 😎
Hi Peter, wow 24 ltr tank 😲 mine's only about 10max I think. Yep regulator and oil / water strippers are indispensable for best results 👍 Sounds like you have a nice setup there. Mine is the Revell Master Class with all the trimmings so sort of semi-pro 😉 I also have two 'guns' (one single action and one double action) for large and small quantities and a variety of needles and jets from fine line (without the guts to test it yet😁) to large areas like hulls. If you go to a DIY place that the pros also go to (Building Supplies?) you should find acrylics in half and 1ltr cans. For my 'grey ladies' (up to 1.5m long) I use the 1/2 ltr cans of RAL standard colours, e.g. RAL 1001 is medium navy grey, RAL 7035 is a lighter grey more like the RN hull colour. 1/2 litre thinned to the consistency of milk (low fat😉) does a lot of hulls and you don't want it to harden in the can do you! 😡 A good shop should be able to mix any colour you want. Take the paint chart with you and the mixer should be able to look up the mix code on a computer. If he hasn't got one - go somewhere else!! You should also find the primer filler there (usually only grey I'm afraid), if not go to a pro car supplies shop - you'll find the Protection Lacquer there as well. Cheers Doug 😎
Started the long job of sanding down today. I think this is going to take a while. During last week I spent the time removing all of the deck parts still attached. The motor, rc gear, rudder, batteries and prop shaft have also been removed leaving the basic hull and decking superstructures. I have visited my local model shop today to see if I can sort out the paint. I have decided on acrylic but the cans are so small that I would need loads. I also cannot find a suitable red for the hull bottom. I am looking for matt. I was also considering making the main colour Pacific Green or similar. I have found Navy Grey which might have to do. If anybody can help with where to source suitable paint in reasonable quantity I would be grateful. I have purchased the sanding sealer and primer. I was considering air brushing the whole project but not so sure now. Any thoughts?😁 I have taken pictures of the progress so far. A lot of sanding still awaits me.😡 I purchased two Mk 17 gun carriages for the tubs. I cannot believe it but they fit perfectly. A picture of these is also below. One last question for now. Should I brush paint, air brush or spray can. The boat is 40" long. Another long day of sanding tomorrow but with greater care as I am tackling the skins. I remember how thin these were when I originally constructed the model.🤔
