You can still get greases that are applied in liquid form but they now tend to be in spray form. I personally do not use silicon oil or grease, it is fine until you need to repaint your boat, it forms a film that is almost impossible to remove, even cellulose thinners has no effect and any paint applied fish eyes and separates, there are dedicated removers but we tried one on a contaminated bike frame which had been blasted, with poor results we had to treat it several times and had to reblast it, we discovered silicone grease had been used in the bottom bracket. Keep silicone away from any surface you may need to paint.
The boat is nearly complete now, the final part is to fill the deck with fill nets! I have found that the Heinz snap pots for baked beans are the perfect size! Top removed, sprayed and weathered and then a body buff has been cut up and stuck inside along with some twine. I’ve then painted the net to make it look dirty and some varnish to give it a wet look.. 2 down 1 more full one required and then a stack of 3 empties... but first dinner, and yes, it’s beans on toast for me!!!
Well it is nearly Christmas again and time to go to my testing river in Hungary. This boat will not be ready but I hope to complete the Police Launch this trip. I have started the painting process on the Pilot Boat. Very early on I had a dilemma. When is the correct time to paint. As I generally use rattle cans and an airbrush, I think it best to paint prior to major assembly. I am still not sure if this is the correct approach but I am concerned with masking an assembled unit. I hope that the glue does not ruin the paint finish when I put it together. It is a bit difficult spray painting this time of the year due to the fumes. I spray in the garage with the door open but I am always concerned about air temperature. The finish looks good so perhaps this is not of great concern yet.🤓 I will now leave the hull to dry prior to applying the lacquer. I have completed the insides of the bridge and rear room and will start to assemble this part next prior to masking and painting the outside walls. I have bought a roll of special low tack clear film to protect the windows and frames. I hope this works. I have used the same film to cover the instrument panel which so far seems to be staying on well. I think that these models by AeroNaut are really well designed. It still amazes me that the model looks so natural even though it is made generally from flat thin sheets.😉 I will attach the deck next and then start on the main structures. Happy Christmas to all.
If they are enamels like Plastikote used to be, yes, but as far as I know, Plastikote changed formulae to acrylic, which, if their brush pots were anything to go by are complete crap. I had one that reacted with itself! I complained bitterly to them and they sent me every pot of enamel they had left in the office! Martin
Hello from Australia, First start off with a scrap piece of plywood the same as you intend to use for the deck. Work out the width of the planks and score lightly with a scriber (not to deep). Using a ruler or suitable guide ,mark the lines with a no 3 fine tipped marker pen. wait till dry(usually 24hours to stop bleeding) then either spray or paint on satin laquer. (3coats). Always works for me. Good luck. Sid
Hi Neville, Check out my Sea Scout 'Jessica' renovation blog for how to achieve good paint finish! 'Wet n dry' is the ONLY way to go. Right from the priming stage. It stops the 'riding' you describe and the generation of flying dust which is anathema to any paint or varnish finish, but you do have to clean and re-wet the paper and the object you are sanding from time to time!!! Any mistakes at that stage will carry through to the top coats and still be visible 😡 Don't quite understand how you created 'mouths'. I'm wondering if you sprayed too close and/or too heavy!? Your apparently exorbitant paint consumption seems to hint at this🤔 For the record; I started with 240 on the primer/filler for my Sea Scout and worked up through 400, 600, 1000, and 2000 and 3000 for the final top coats and deck varnish. All 'Wet', with a few drops of liquid soap added at the top coat stages, i.e. from the 1000 stage. At the end I polish with a mild cutting polish 'Anti hologram' they call it here, from the auto industry. Tedious I agree and a generous dollop of patience is required (the 'Secret Ingredient' I have often mentioned here 😉 But when you see the result it warms the cockles and makes it all worthwhile.😊 Happy spraying, cheers, Doug 😎 BTW; for the blue on my Sea Scout hull I used a 400ml rattle can for several coats (more than three in the end) and there's still some left ! BTW2; For masking I use Tamiya tape for nice crisp edges. Fill in behind that with 'normal' fine masking tape and newspaper.
Well had a break of a few weeks, now back on the job. So now have a Red Oxide boat rather than Yellow one……………… Although these next stages are a bit ‘ samey’, I have learnt a few things as it happens. For example, I had put three coats of the Halfords filler/primer on a couple of days before I had a break. Now when I left it all looked dry, well covered and ‘solid’. When I came back to it some weeks later the longer drying period had shown up some gaps. Well not gaps actually but ‘mouths’ where tissue I had overlapped had pulled apart slightly. Interesting, easily fixed with some 240 grit sanding, showing that the drying period is longer than it would appear. At least for filler/primer which is a much thicker substance than just spray paint. With the sanding, I had not appreciated the difference between the grades say from 240 upwards (or is it downwards) as my experience was with doorframes and floorboards. For the stage I am at, 240 and 400 seem very effective and leave a good surface. What I did find was how important dust becomes……………… The sandpaper rides on it (the powdery dust) and so becomes much less effective and I found brushing with a thin 2 inch brush worked well, using the vacuum cleaner to clear up later. I did try blowing it off with the heat gun but that put the dust up in the air too much. It is my intention to try ‘wet and dry’ approach for later coats and looking for a better answer when it comes to finishing coats. Another interesting discovery was coverage per rattle can. It may be my ‘beginner’ technique, but it seems to take a lot of paint. On this size of boat hull, 44inches (112cm) by 14 inches (36 cm), it took a 500ml rattle can of yellow filler/primer for three coats. For two coats of the red primer it took the whole of a 300ml can. Also discovered, using these ‘rattle cans’ for the first time, that the primer on its own comes out differently to the filler primer. This unsettled me for a minute or so but appreciate may be due to the different density so will be aware next time. Another issue that became obvious was…………..I must improve my ‘masking off’ ! So that is it so far. Next stage is - going to buy a couple more cans for the finishing coats, do a bath test, mark the white line point, more sanding down and then start applying the finishing coats. Any helpful comments will be much appreciated. NPJ
Ah! I thought Fairey might prove the exception to the planking rule. Well, it'll look nice, that's for sure. Paint. I always use enamel and my local auto paint shop will make me 1/4 litre tins up, of HMG, which lasts a long time from a small spray gun. Failing that, Rustoleum do some lovely rattle cans in a range of colours that spray very well and are only just over a fiver a tin. One tin would do you if you're careful. I've just given my Darby One Design its second coat of blue after a rub down and I'm happy with that. Dries very quickly, but is a nice gloss. It is a bit thin, so be very careful how you spray. Better to do two coats than one thick one. But really, if you can get it, HMG is the best bar none. Worth hunting for. Paint, alas, just ain't cheap anymore. Would that we could get tins of Valspar or Japlac, eh? The proper original stuff. Plastikote was a good paint when it was an enamel, now it's acrylic water based muck. No coverage and reacts with itself, let alone owt else. I would be inclined, btw, to do that curved deck in veneer, so all your mistakes will be made before it goes on the boat. In which case, once the planks are made and fit bang on, go up the edges with a black marker pen. It will look like caulking when all is done. Good luck, Martin
This build is proving to be much more difficult than I had expected. 😤 I think I started this project thinking that all of the parts were ready to fit and glue. As I went on, it became clear that this is not the case. Due to this, and as detailed in the earlier post, I have had to break down the glue joints of the hull frame, and reposition after deepening some of the assembly slots. I have re-assembled the bulkheads, stringers etc. and then started to fit the side skins. This has proven to be the most difficult task so far. You need six arms. After several failures, removal of all of the fixing tape and then starting again, they finally started to look reasonable. I watched a time lapse video on you tube and he seems to do it fairly easily. Oh well. 🤔 Now that I was happy with the fit of the sides, it was time to start on the bottom skins. I started by trying to form chamfers along the keel centre joints so that they look reasonable. Then I once again applied tape to hold them in position whilst glueing with my other three hands, I wish. This only took two attempts. I must be getting better. I still have most of my hair also. Next, I tried to mount the motors onto the angled bulkhead. The front location was very loose so I made a couple of thin silver steel rings to improve the fit. They work very well. 😊 Next job was to fit and align the prop shafts. I decided to make these solid joints and avoid the use of universal joints. The first motor went straight on with perfect shaft alignment. The second was not so good. After two hours of fiddling with a packer, I finally achieved perfect alignment. Next job was to give good joint strength and make the hull water tight. Rightly or wrongly I use a lot of glue to give that perfect seal. I used epoxy for all of the skin inner joints and Stabilit for the outer seams and joints. I used the Stabilit around the shafts as well which looks a little messy at the moment, but I will tidy all of this up next. I will paint the inner Stabilit with white paint to hide a little. This weekend I will do a water test to ensure it is water tight.😱 I think after that I will fit all of the electrics, servo and speed controller. Then I will spray the hull and the main deck prior to fixing together. I would be interested to know what others think about when to paint, before or after assembly, especialy regarding the hull. Enough for now.🤐 I will try to speed up the build a bit now as I am expecting the new 46" Crash Tender to arrive soon. Wood!!! Love it.😊
.... and make sure the working area is well ventilated, an extractor fan helps enormously, as also with spray painting or soldering (esp with the old lead based solders). It's the solvents drying your skin out, removes all the skin oils. Can make your eyes sting as well. 😭 Cheers, Doug
Just got white metal castings back of the Chris Craft fittings and very nice they are too. They have started to burnish up a treat and will polish well as Paul uses a good quality metal. Nice and hard. Now I have to make the light lenses. Also put the blue bottom on her at the weekend using my one and only pot of Plastikote enamel paint, not the acrylic muck they've turned over to and it went on through my spray gun as smooth as could be. Even my masking worked. Just waiting for a gold pin stripe tape for the boot topping now. The final bit will be masking the deck to paint the covering boards and king plank with the same blue. For those not lucky enough to have a wee pot of proper Plastikote in the paint cupboard, I also got a couple of tins of Rustoleum spray, only 5-25 a pot, enamel (of course) in a nice French blue and a rich cream. These colours will look good on my Darby One Design single stepper "WHO'S DARBY?". Very post War. I think the Oulton Broad One Design single stepper will be Burgundy and the Whippet One Design will be varnished mahogany. I know of no other classes of British stepped hydroplanes. These will all be 1/6th scale as they're all around 12-13 ft. long. I'll probably put the same motors in them eventually. The Darby is well advanced and has a Speed 400, but I may go brushless. Any suggestions for a cheap Brushless/ESC combo will be welcome for, say, 3S Li-Pos. It would be good to see these period boats all racing together. I also plan to make reverse clinker Singer cadet and a Percy See Bugatti engined boat for which I have plans. I'm hoping to get a response from the current keepers of Berylla II about measuring that, too, since it also uses a Lea Francis engine, like the Whippet.
Hi all, got my Crash Tender bottom sprayed red today, so I'm nearing when I'll need the hull decals for FIRE, roundels and numbers. Anyone know where they can be had from? Also what does that stuff on the bow say/look like. I can hand paint that if necessary. Cheers, Martin
Hi Neville, I recognise the 'I want it all and I want it now syndrome' cropping up again😉 Wev'e been down this road before haven't we!? You don't have any "structural' problems. The original builder simply cheated and covered over the 'back bay' instead of fitting it out. And - Why do you want to mess with the cabin tops? To get the boat going for some fun just leave the superstructure like that for now and think about it and fiddle with it in the winter. The deck looks fine from the photos. Just flat off with some 1000/1500 grit wet & dry and give it a spray of medium sea grey and finish with satin or matt varnish. After you've fixed and repainted the hull. If you do all we've said to fix the hull, and apply the fix up to the joint of hull and deck there will be as good as no chance that the deck will leak. When all is said and done YOU saw the boat before you bought it and YOU had a specific purpose in mind apparently. Namely; some quick fun. Soooo - fix the hull, have some fun learning to drive it, and leave the fiddly bits and embellishments until the 'closed season'. Then you can deliberate and decide if you want to restore it as an RSL or convert it into something more exotic. Looking forward to your cogitations on the electrical layout😉 What Action bits are you thinking of using? BTW: if you had a fire at all with the heat gun either you have it too hot, turn it down to about 300 -350°C, or you're hanging about too long in one place. The gun should only be just hot enough to start the paint surface bubbling up. ATB Doug
Added a 60A ESC of Chinese origin, improved waterproofing, and modified the rudder water pickup. Repainted trim tab extension as while it sat in the test tank (AKA the bath) the water got into the wood and split the paint work car spray paint not as water proof as I had hoped. On the test I found it was pulling over 40Amps which is not what I want as this is a race boat with limited battery capacity so cut down propeller by filling of the lagging edge of the prop via a drimmel and a file, so now pulls under 30A at full throttle. At the pond I will check current and prop-sizes.
