Roof Skins by mturpin013 Captain   Posted: 10 hours ago
Oh dear, that looks really good and the overlap of the window frame on the surround should keep the water out (maybe) I suppose a light/thin 0.5mm piece of dense foam could be incorporated as a seal. should I do it or just get on with plans already made? at this rate It will never get on the water. decisions- decisions. Any chance of a few more pictures of this boat it looks really well constructed and may well have some other good tips.

Sanding down. by MouldBuilder Sub-Lieutenant   Posted: 11 hours ago
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.🤔

Cockpit detailing by Skydive130 Fleet Admiral!   Posted: 2 days ago
Not a great deal of action today, had to do some the as detailed by the “mrs”! Added the forward cockpit coming roofy thing, shaped, sanded, filled, sealed and sanded again. Last thing today was to build a pair of simulated engine intakes. My be a few days till more work now as back on shift

Cabin Windows by mturpin013 Captain   Posted: 3 days ago
Now the cabin roof mechanism is working I have to finish all the detail in the cabin before I effectively seal the cabin with window frames and roof skins. However I thought I would check the fitting of the windows and roof skins just as a change from detailing. Because the roof is now movable it means the roof skins will need additional support. Also the windows as given were short in terms of height and the roof skins only fitted where they touched and both would need some remodelling/remaking. I decided to remake the windows out of 1.5 mm ply instead of the 1mm supplied in the kit and resize the overall dimensions and then slightly reposition the window openings. The 1.5mm will also accept the plastic windows within the opening instead of being just stuck to the inside.

Bristol pilot cutter mascotte by kmbcsecretary Lieutenant   Posted: 3 days ago
Hello all this is my latest build of the Kingston mouldings Bristol pilot cutter 'mascotte' was purchased from a forum friend who no longer had time to build it. Sadly Kingston mouldings has now closed down. The first job was to glue the lead ballast into the bottom of the hull, this was done by using fibreglass resin then a couple of layers of fibreglass to seal the lead shot into the built in keel

The Lone Ranger Rides Again or Hull Finishing ;-)) by RNinMunich Fleet Admiral!   Posted: 4 days ago
Addendum! Attached a pic of the selection of artists brushes I have found useful. As well as 3 tubes of oil colour useful for weathering effects; detail highlighting, dirt, rust etc. 😉 Seal afterwards with a quick blast of clear satin or matt fixer / varnish. The 'fixer' is also useful for fixing inkjet printed colour photos and oil or water paintings 😁 Clean brushes with artists turpentine or white spirit. Ciao Doug 😎

The Lone Ranger Rides Again or Hull Finishing ;-)) by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Boatshed, Know what you mean about brushing and brushes! You CAN achieve the same effect with brushes, but it takes much longer, with much more flattening in between coats. So much more 'secret ingredient is needed! Brushes from DIY shops, and most model shops, you can forget 🤔 too synthetic, too coarse and too prone to shedding hairs. 😡 For tiny detailing work, esp on Plastic Magic projects, I went to an art supplies store! Prompted by the GF who is into oil and water colour painting! There you will find a great selection of very fine real hair brushes in sizes from 'Help I can't see it'! to about 1" flat, used for applying 'washes' 😉 Not cheap, but quality never is! For example; I'm using a 1/4" flat camel hair brush for renovating the wood decks of my Graf Spee and HMS Belfast with sealer and satin varnish from the Lord nelson range. Will also apply some Jotica Oak stain to dampen the bright colour a bit. For the pinstripe / Boot Topping on the Sea Scout I'm 'Going for Gold', to be applied with the finest airbrush nozzle I have and using Tamiya masking tape to get a good clean edge. hardest part will be getting the tape on right 😲 Hope I don't mess up what I have already achieved! Cheers Doug 😎

HMS HOOD by Trumpeter by RNinMunich Fleet Admiral!   Posted: 6 days ago
Hi Steve, Great! Worth all the searching, waiting and effort 👍 A word to the wise! Don't rely completely on the self-sticky back! I made the experience with my Graf Spee that it tends to lift at the edges, and always in the most awkward places to get to 😤 - Thanks 'Murphy'! Recommend gluing round the edges with a medium thick gluper-sue!! Or sealing with a thin type if already fixed on! For my Flower Class, PoW and Bismarck & Co I shall stain the wood decks with Jotica Oak and then seal with Lord Nelson Sanding Sealer, as I also used on my Sea Scout. Followed by Lord Nelson spray satin varnish. BEFORE I fit it to the ship!! I am also going to refurb the decks of my Belfast cruiser and Graf Spee the same way. Keep on blogging, cheers Doug 😎 BTW: loved the antipodean 'deck' care instruction!! 😲😉 Would have loved to have been a 'fly on the wall' when your Missus found it! Can almost imagine the giggles 😁

The Lone Ranger Rides Again or Hull Finishing ;-)) by RNinMunich Fleet Admiral!   Posted: 7 days ago
Sooo ... Happy with the cabin and main deck so onward and upward with the hull. At a previous stage the hull was already sealed, primed and two coats of gloss Royal Blue, or at least what passes for Royal Blue in Germany - seems a little light to me but I like it anyway. Over-spray from other operations was sanded off with a 600 grit sponge. This revealed a few imperfections around the bow that needed sealing (EzeKote) and re-flattening. No one's perfect!😉 These areas were re-primed using a primer-filler from the pro auto branch, flattened off with 1000 and 1500 W&D and the whole hull given a quick blast of Royal Blue again and flattened with 2000 grit wet. Pic 1. The finishing coats were then applied: 3 coats blue and 3 coats protective lacquer (contains a UV filter😎). Flattening with wet 3000 plus liquid soap between each coat. Finally cutting polish and finishing polish, as for cabin roof and main deck. Polishing might give her an extra knot or so, scale of course😊 Results of all this can be seen in pics 2-6. After removing all the masking tape full effect is shown in pics 8-10. Minor Arrrgh!: the masking tape on the main deck had been on too long and the white on the cabin walls had hardened, so when I removed the tape some paint came with it 😡 No sweat! I'll trim the cabin with a mahogany moulding 😁 BTW: the W&D used here are all Tamiya sanding sponges. Not the cheapest sort of W%D but I'm so impressed with how they work and their longevity that I've acquired a modest stock of grits from 240 to 3000😉 Only slight disadvantage; it's virtually impossible to get old colour out of them, unlike W&D paper, so you need new sponges for a new colour! E.g. I didn't want to use sponges I'd used on the blue hull for the white cabin walls!! Big advantage: you can use them wet on raw wood without staining the wood black! So, that's how I've spent the last two weeks, what have U lot been up to??? 😉 Happy painting people, cheers Doug 😎

Main deck and cabin walls by RNinMunich Fleet Admiral!   Posted: 7 days ago
Sorry the advertised Flash Gordon reel has gone 'walkies' so you'll have to make do with this boring description of how to occupy a day or three and stink out the house!😁 After the eventual success with the cabin roof I continued with the main deck using essentially the same process. First I had to extend the planking (engraving) from cabin leading edge back to the transom. Dad had only done the foredeck. Pic 1 shows starting point. AKA Square One! Pic 2 after initial staining, pseudo planking and sealing. Plank engraving was done with a fine hardened steel scriber / centre punch and a steel rule clamped at 7mm centres. Rule was aligned so that the wood grain pushed the scriber against it. Don't ask how I realised that that was the way to do it (minor Arrrgh!)😡 Anyway, worked out in the end. I had started with cherry wood stain but it came out too bright red so from Krick I obtained some Jotica mahogany stain (also some Oak stain for the decks of my Prince of Wales and Bismarck - but that's another pair of Sagas to be.) Using basically the same process as for the cabin roof: two sealing coats, two matt varnish primer coats, two gloss varnish coats, two protective lacquer coats, polishing with cutting polish and top gloss polish, and lots of patience and elbow grease (this time an Italian Lugana😉) pics 3 to 5 show the result. I'm 'appy with that 😊 Note: to remove build up of sanding residue from the 'planking caulking' I had to resort to an old toothbrush or nail-brush from time to time. The sponge couldn't hack it. The aft deck 'hatch' is still the temporary bodge-up I made 25 years ago to quickly get the boat going for my daughter. Think the ply (ca 4mm) came from the back of an old bureaux! Haven't decided yet whether to make the new one from the same mahogany as the roof or thin ply and stain like the main deck. Suggestions welcome please. After the deck time to turn my attention to the cabin walls, looking pretty shabby and full of over-spray - pic 6 😲 Step 0: masking off, pics 7 & 8 'All Dressed Up and Nowhere To Go'🤔 Step 1: mucho sanding starting with 180 grit and working through to 600 ensuring removal of all traces of blue as I wanted the final finish to be Arctic White (not Ice Blue!) Step 2: two sealing coats, flattening with 600 grit. Step 3: spraying with Revell white primer, not impressed, gave a rough dusty finish🤔 Step 4: sand off Revell muck, flat back with 1000 and 1500 grit sponges, respray with two coats of pro white primer, flattening with 1500 and 2000+ soap respectively. Much better 😊 like the proverbial baby's ...! Step 5: two coats of gloss white, same make as the primer!!!, flattening with 3000 grit sponge, wet + a drop of liquid soap. Step 6: two coats of protective lacquer as with the varnish. Flattening with 3000 and soap between coats only. Interesting effect with this lacquer and the paint (as opposed to the varnish); it seemed to 'melt and fuse' with the paint surface and smooth it out.😊 Just had to be careful not to apply too much at once in case it all ran down and took the paint with it! Step 7: finishing with cutting polish and anti-hologram polish. Results: pics 9 - 11. Final effect makes it look and feel like plastic or fibreglass, almost forgot that there is wood underneath😁 Next in this theatre "Hi Ho Silver Awaaaayyyy!" (Sponsored by KiOra!) or 'I'm gonna finish this hull if it kills me!' (sorry Flash reels got lost in the post😡) Cheers Doug 😎

The Saga of the Cabin Roof or - Arrrgh! by RNinMunich Fleet Admiral!   Posted: 7 days ago
Evenin' MT, Thanks👍 Yep I know blooming from my car restoration days. Causes a dull satin effect with some whitish fogging 😡 That's not what happened here, suddenly a patch of yellowish spots appeared under the gloss!😭 Only thing I can think of is that with the last flattening with 3000 grit I used a drop of liquid soap to lubricate the sanding sponge, gives that almost glass finish. Maybe some soap residue was still there and the next lacquer coat reacted with it? The soap is a trick I learned during car repairs. Of course then I could wash it all off with a big sponge and chuck a bucket of water over it! Not such a good idea with a model wooden boat🤔 Re 'Your skins' 😲 I used mahogany 'because it was there' and I suddenly had a picture in my mind what it could look like (Riva style😉) if I could do the job right! I'm pretty happy with how it eventually worked out 😊 Not sure that a mahog roof fits the image of an RAF boat? and painting it would be a shame 🤔 But if you do decide to use it you may have more luck with 0.5mm, mine was 1mm+. What are the 'existing skins'? Re clothing: I didn't do that, didn't want to risk obscuring the wood grain on the outside and the inside I had sealed with two coats of EzeKote anyway. Cloth would have been superfluous. But if you're going to paint the roof anyway then - why not? Would give strength and rigidity. Thicker ply? More than 0.5 / 0.6mm and you may have the problem I had with the compound curve!!! Cheers Doug 😎

Skirtless hovercraft by reilly4 Commander   Posted: 8 days ago
Mr. Grumpy - The reason for a hovercraft skirt is to provide a flexible seal between the craft and the ground/water surface. If everything was flat and smooth, then a shirtless hovercraft would probably work, as a uniform cushion of air could be maintained. Unfortunately this is not reality. I used to like the concept of a hovercraft and once keen to model one, but having seen real ones and models lack of directional control have gone away from the idea. Another reason for the skirt - bouncing off nearby objects in the vicinity of the hovercraft.

The Saga of the Cabin Roof or - Arrrgh! by RNinMunich Fleet Admiral!   Posted: 9 days ago
Typical of Aeorokits the cabin roof skin was made of two thin pieces of ply < 1mm. Over the 50 years or so the overhang corners had started to curl up and crack 😲 Pics 1 & 2 show the 'off the shelf' condition after 25 years of neglect 🤔. First I tried to correct this by soaking in hot water and flattening under a car battery (flattens most things😉). So far so good. Then some super glue in the cracks and back under the battery. After a day or two it just curled up again. Ho hum! Pour a glass of wine and back to the thinking board. Seconds Out - Round Two! Thought, OK make new pieces from the 0.6mm ply I still have and paint it - then my eye fell on some 1mm mahogany sheet (Ouch 😭). Tried to make the whole roof skin in one piece of this but the compound curve defeated me. The skin was steamed and soaked in hot water and clamped across the roof frame. Next morning - Arrrgh! Had started to crack along the centre line 😭 More thinks!! Carefully cut down the middle and glued and clamped the separate pieces; pics 3&4. Getting the two pieces to match in the middle was a tedious ***!!! Pic 5. Then mucho sanding. followed by 2 coats of Lord Nelson sealer, sand back with 600 grit sanding sponge. Then two coats of Lord Nelson matt varnish, sanding with 1000 grit in between. then two coats of Lord Nelson gloss varnish, sanding with 2000 grit in between. Pic 6. So far so good, pic 6. 3rd coat of varnish and - Arrrgh 2! 😡 Pic 7. No idea why! Sand off and start again, pic 8 😭 Treated each side separately, pics 9 & 10 and flatted off with 2000 grit. Then applied three coats of clear protective lacquer, sanding with 3000 grit between coats. Finally cutting back with auto paint restorer / cutting polish and finally polishing with anti-hologram finishing polish. Pic 11. Now I'm happy 😊 Pic 12. Only took a week 😉 Next week in this theatre - "I love you too Flash but we've only got 15 minutes to save the world"! or 'Will I ever get this hull finished?" 😎

Rear Cabin construction by Skydive130 Fleet Admiral!   Posted: 10 days ago
today has seen the rear deck and cabin constructed. I lined the deck piece with some mahogany strip for a neater finish on the edge of the crapy liteply. Construction of the cabin was straight forward, this was followed by shaping, sanding, filling any gaps and a couple of coats of sanding sealer ready for paint. I have also added the railings and stanchions to the roof of the cabin as a start to the detailing to come. I have ordered a book from Amazon which is a reference book of the Waveney Class lifeboats, so hopefully there will be ample photos for the detailing I hope to add as we go on!

more progress. by Skydive130 Fleet Admiral!   Posted: 10 days ago
First job today was to reduce the rudders by 1cmx1cm which I think not only looks better but should reduce the affects that have been mentioned in comments below. Ive fitted the cockpit which I assembled yesterday. Its not the best fit into the deck, however, I shall blend it all in with some balsa strip, sand, filler, sanding sealer hopefully for a seamless finish. I have pictured the 2 x Hobbyking waterproof boat 30 amp esc. These are supposed to be water cooled, however I am not going to fit the tubing and start drilling water pickup and exit holes in the hull x 4 until I think that water cooling is going to be necessary. Once I have watt meter readings for 2S and 3S lipo, it will give me an idea what the ESC are going to be like. Of course if you guys think I need to go water cooling, please let me know! I have an Mtroniks W-tail mixer that will allow the motors to be synched to the rudders allowing the inboard motor to slow or stop when turning. Never used one before, so may need to some programming once hooked up, we shall see. Last job today was to shoot a could of coats of red oxide primer on the lower hull to see what the resin finish was like. on the whole not a bad finish at all, just a could of tiny areas that need a little sanding for a faily blemish free finish.
