Sports cruiser "ALI" by Joe727 Fleet Admiral!   Posted: 26 days ago
Hello, Looks good! I use PVC for all my wood. CA is not very water resistant. If you can get the waterproof type PVC, use that. If not, if it is just a white glue, make sure all glued areas are covered with a waterproof coating. Such as varnish or paint. When I glue wood, I put glue on each joint, let it sit for a few minutes while it soaks into the wood grain. Apply a bit more glue and press together. Clamp or somehow hold the joint securely while it dries. Most PVCs take at least 30 minutes to set. Depending on the joint, I usually will come back a day later and fill any gap that may appear. PVC creats a joint stronger than wood. CA is brittle and the joint can snap. Give it a try and good luck to you. Joe

Cleaning sails, toy yachts, etc.... by Westquay Fleet Admiral!   Posted: 3 months ago
Useful to know about Vanish. It certainly worked on my Star yacht sails. Fortunately the sails on the Ailsa yacht are lovely anyway, just some new rigging cord required. I would say the sails were the same as bed sheets. I used some white spirit to clean the deck on the Ailsa. Most of the dirt being handling muck. Then I waxed it with 3M wax...twice. It's wonderful stuff which I bought for our historic narrowboat's new paintwork. It was a wooden boat and when I replaced the cabins and had painted them with Tra-mar Coatings hand made enamel paint, I waxed them with 3M's wax and they went another 3 winters before I sold the boat, with the rain still rolling off in beads. The Ailsa is now waiting for some spar varnish over the repair's creamish paint. I couldn't match it perfectly, but I didn't want to repaint the whole hull. All the repairs are under the waterline so it shouldn't show. The Star...I never heard of them using aluminium for masts. How would they have kept the rigging eyes in place? Martin

Now Coating and Matting by NPJ Fleet Admiral!   Posted: 5 months ago
Thanks for the encouragement Donnieboy. Hope to move it forward today to the tissue bit in the way you are suggesting. Fittings may end up in a selection bag on Ebay! TTFN. NPJ

Now Coating and Matting by Donnieboy Fleet Admiral!   Posted: 5 months ago
After the application of fibreglass or matting i usually put on a second coat of EZ-Cote.After drying lightly sand.Overlaps I find easy to level up with another coat of EZ-Cote.I have been using the same bottle for 3 years.That stuff really stretches.All the wrong size fittings can always be used on other projects or modify them to suit yours.

Now Coating and Matting by NPJ Fleet Admiral!   Posted: 5 months ago
On to Coating and Matting. (as well as sanding!) Now have at least finished all the stripping. Then did the ‘bright light in the hull bit’ to look for areas that needed patching. The major problem area was in the bow and that did not receive the light as it is a totally blanked off compartment. However, it was obvious from the outside anyway so, could I assume it was the only leak? Decided to put a fine matt over the whole hull, not deck, just to be sure of best chance of success. I can imagine what will be said here if it still leaks after all this! I had ordered some supplies ready for the next stage and drew up a plan view of the boat to help think through layout of electrics and other items. Made my usual mistakes about size. Some fittings purchased too small………However, never too large now that’s interesting. Some materials purchased too large. Now have a life’s worth of Resin……(when does it ‘go off’ by?) Also have a lounge floors worth of tissue matting! Also Sandpaper. Now there is a mine field. So now I know a bit more about that and which way the numbers work! When I forgot to put the mask on, I had some of the crispest 'bogies' in years.............. No images posted! On the plus side, although I never wanted to get into this stripping sanding, filling sanding, sealing sanding, matting sanding, painting sanding, painting, sanding bit……………. I now feel I started out with someone’s boat I had bought and now it has become “my boat” for real! I am at the stage now where I have put some filler in and applied the first coat of Eze-Kote from DeLuxe Materials To use Eze-kote read stuff from RNinMunich on this blog or the’ leaking boat’ thread. Washes out of the brushes very easily. There is such as this ..... Youtube link - watch?v=yP05qv3QtUk RNinMunich or Colin H. and the like have bits of extra comment and experience that is always very helpful. BTW, after that finer sanding before first coat, I did the dust down and vacuuming bit but it still felt a bit ‘chalky’ so I gave it a wipe with Methylated Spirits. Now I realise that has water in it, so if anything goes wrong it could be blamed on that................. Having left the first coat to dry I started to cut out the light matt to apply after the next sanding. The matting I have is called Glassfibre Surface Tissue EGlass from FibreGlass Direct. A part of Tricel Composites (NI) Limited. Available internationally in lengths from a metre upwards, it is quite fine in weave so we shall see what happens. I have left quite a wide margin at the moment but may reduce that when I have tried using it! This is another first for me so plenty of room for mistakes............... Will need to cover with the matt in stages as I cannot get around all the boat without changing its position. Going for the bottom of the vessel and stern board first as I figure they are going to be easier than some of the other bits. Then will leave that to cure before moving the boat. Really worried about the joins/overlaps and how well I will cope with those, not to mention the curved bit! Started to look at electrics and layout for a bit of a change. I will post again when I have had the first battles with the matting! TTFN. NPJ

Leaking Boat! by marky Fleet Admiral!   Posted: 6 months ago
Seal off the gettable area with polythene put the hull in the domestic test tank then using a cycle pump put air into the sealed area watch for bubbles appearing (like looking for leaks in an inner tube) No bubbles no leak, move to the sealed area drill a small hole enough to get a football valve adapter in and again apply pressure and look for bubbles if there are bubbles and this is where the leak is you could enlarge the hole that the adaptor was fitted through and pour in some sealer and swirl it around .or cover the whole of the exterior of the hull with a liberal coating of clear sealer . Cheers Marky

Range Safety Launch? by RNinMunich Fleet Admiral!   Posted: 7 months ago
Evenin' Neville, Re Leak- Where did the water collect? Anywhere near the end of the prop-shafts? Whatever; as soon as it's dried out give it a good internal coating of EzeKote from Deluxe Materials, no pong and no hardener resin. Brush it on generously and leave to dry/harden overnight. Put PLENTY down in the bilges around the keel boards. Brushes you can simply wash out in warm water. Very 'People friendly'👍 After that carefully inspect the outside of the hull for flaked paint, cracks and delamination of the skin or keel wood. Re scale for fittings- "Some of the 1/16th look better than the 1/12th and 1/24 is in with a change for some bits!" Don't quite get the last bit! Whatever 😉 The original was LoA 43' = 516". So your model with 44" is without doubt as near as dammit 1/12. (1 to 11.727😁) Owt else for the fittings would look a bit 'Gulliver's Travels' 😲 Re Build Blogs; the most comprehensive one I've seen here on Fireboats is Robbob's outstanding build and incredibly detailed and informative blog 👍👍👍 https://model-boats.com/builds/view/23951?goto=44797 Can't wait to see what electrics you've ordered, another big white delivery van full of surprises?😁 Bon chance mom ami, Cheers, Doug 😎

46Firefloat Mk2 paint by Westquay Fleet Admiral!   Posted: 7 months ago
I found that Chinese 5 spice powder worked fairly well, but getting an even coating is difficult, especially where it's always windy like here. I shall be making the davit and hook mechanisms in brass and getting them cast. There are none available as far as I know. Martin

46Firefloat Mk2 paint by Westquay Fleet Admiral!   Posted: 7 months ago
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

Crash Tender davit info... by Westquay Fleet Admiral!   Posted: 8 months ago
Doug, the trick to a good even sprinkle (oy, madam) is height. A more even coating results from a good high sifting. White pepper can be good too, though might cause a sneezing fit and then the jolts would result in molehills I might pop to Halfords and have a wee look tomorrow. They're just across from Wickes. Cheers, Martin

Crash Tender davit info... by robbob Fleet Admiral!   Posted: 8 months ago
Martin. The 'Deck Anti-Slip Finish' bit is on page 4 near the top. Re: Colours. As there seem to be no colour photographs or film of the boats the question of colours for the decks, cabins and roofs is open to speculation but you are quite correct to point out that the plans do not specify white for anything other than the hull markings. The cabin roofs I believe would indeed have a textured coating as the crew were required to stand on them to operate the monitors etc. but I decided not to replicate the texture as is would just look like a bad paint job! I did carefully consider the colour options when painting my boat and decided to texture the deck and paint it in the colour specified ‘BS631 RAF Light Grey’ but to leave the cabin roofs untextured and painted white as that seems to be the consensus, and to my eye it does look 'right'. It is also a great shame, as you say, that one of the most popular RAF boats were so few in numbers and not well documented or photographed during their service life. I have a suspicion that a book of drawings and specifications does exist somewhere as I have seen a few pages that appear to have 'Ministry of Supply' indexes and page references. The 'Plans & Docs' section of this site has some useful information and some 'photos and drawings but they are of very poor quality and resolution. Wouldn't it be nice if whoever has that resource were to make it generally available, I believe it's out there somewhere. We can only hope. Robbob.

Fibreglass the hull- continued by mturpin013 Fleet Admiral!   Posted: 8 months ago
Now the Chine rubbing strakes are fitted, dry and filled and I have attended to the minor lumps and bumps the next job is to give another coat of resin, taking the issues of the first application into account I intend to apply a thin coat, this has the effect of filling in the pattern of the glass cloth. Another two days have passed and it’s time to do some rubbing down. I have found that the surface is very hard, more so than I recall some of the other fibre glass projects I have done but these have been using Polyester resin. It’s a first for epoxy, so is epoxy a better choice than Polyester? According to my mini research –  Epoxy is more versatile  Epoxy has fewer fumes  Epoxy is stronger  Epoxy shrinks less Conclusion Epoxy is the better choice for repairing/covering either wooden hulls or repairing fiberglass boats. It has excellent adhesive qualities, wets out fiberglass fabrics and it is tough. It has great thin film cure characteristics, cures in cool temperatures. After the first coat I wasn’t 100 % happy with the finish but I just thought that some dust had landed on the surface before the resin had dried, (this was proved not to be dust but because of the matting pattern still been visible it disguised the real problem) however this was easily sanded out with wet & dry. Now the hull and deck were looking really smooth with very little sign of the matting pattern it was time to give a final coat. I had decided to coat both the deck and the hull in one go so I mixed enough resin to do the lot. Starting with the deck I started to apply the resin but to may horror it started to pin prick all over the deck surface, panic, panic what was causing this? So was it the brush which I had previously washed out with cellulose thinners after applying the last batch of resin. I decided to remove the resin and use a new brush (I had 90 mins cure time to do this) so cleaning of with paper towel and finally with a wipe with thinners I started to apply resin again – but it happened again as I sat in despair I looked into the pot of resin wondering where to go next when I saw a film on the top of the remaining resin It was then I noticed a ridge in the cups side. It was the wax coating that had melted into the resin and subsequently appeared as pin pricks in the newly applied surface. At this realisation I removed all the resin again and took a breather hoping I had found the problem. Another day and a light rub down of the deck to make sure the surface is ready to receive its final coat. Resin weighed (in a glass container this time) and well mixed I started to apply again and fortunately it was OK and all surfaces were coated.

Back to the main hull Have finally got the hull sprayed today with this heat it has been drying faster than I can spray it on 😄 Firstly the hull was sanded with a 200grit paper to sand of the shiny coating to give the paint something to key too. It has had three coats of undercoat sanded with 2500grít wet and dry paper between each coat.the undercoat used was Halfords rattle can plastic primer. Then the lower hull colour was sprayed on again three coats sanded with 2500grit paper between each coat.colour used was Halfords rattle can ford arctic blue. the top half of the hull was sprayed with two coats only with it being black plus I didn't have enough paint to give it a third coat😋 colour used was Halfords rattle can satin black. Finally the hull was sprayed with Halfords rattle can clear lacquer three coats sanded with 2500grit paper between each coat.

The Saga of the Cabin Roof or - Arrrgh! by mturpin013 Fleet Admiral!   Posted: 11 months ago
Hi there, Patience is a virtue, of which you appear to have a lot. AS for your slight "blooming /blushing my only answer is (raining or exceptionally cold or humid weather which often occurs when rapid evaporation of solvent cools the air over the coating below the dew point.) (internet is brilliant) however you've set me thinking now as as you will have seen in my blog having got the roof mechanism working I have yet to apply the skins. I appreciate any thoughts on - 1 Using existing skins? 2 Using existing skins and then f/glass and cloth both sides? 3 I have a quantity of mahogany veneer 0.5mm from memory, three sheets cross grain and glue whilst the held in the compound curve? 4 use thicker ply?

K45 8 rater yacht revamp by Bryan-the-pirate Captain   Posted: 12 months ago
The first item is the deck, I was going to remove the white round hatch but the deck is so weak and flimsy without it I had to keep it 😡 Still, a wood strip deck is being laid direct to the old deck with the intention of a clear varnish coating once completed.
