The Upol Barcote product recommended is intended for Industrial use mainly in car restoration. The spec sheet can be seen at http://www.u-pol.com/files/6689/up0720-SDS-EN. If you are intending to use this Full PPE equipment should be worn and only use in a well ventilated area. Personally I use paintstrippers, scapers and a hot air paint stripper to clean wooden hulls back to bare wood. This allows me to see any damage caused by fuels used with IC engines. I agree its messy, takes time and is best done outside, but you do end up with a solid hull with no hidden soft spots. I agree with Jarvo's use of Clear Cote either in gloss or semi matt finish. If the air temp is much below 20 deg most rattle cans will not give a good finish and runs will be difficult to avoid.
Perhaps you have answered the question your self, wet and dry and after a couple of coats you should find it smooth and without blemish. This is the time to ensure there is no dust around. A good idea is to try and make a shelter around the boat and wet it before giving it the final cost of a good quality gloss paint. It really is just a matter of perseverance and you should have a great finish. Good luck! Peter581
Laser cut kit from Barracuda RC Boats, N Carolina, USA. Baltic birch plywood false keel, ribs/frames, hull sheathing, deck and cabins. No formal plans; I was able to source a handful of B&W archival photos from the USCG website. Fortunately I was able to procure a motherload of archival photos and a few hard to read layout drawings from Mr. Timothy Dring, LCDR, USN (Ret.). He is co-author of "American Coastal Rescue Craft", which is the "bible" if you will, of such. I do sometimes thank the internet. I am certain that without his assistance, my efforts on this wouldn't have been as enjoyable. The kit was also void of fittings, which I was aware of prior to purchase, so I invested in a 3D printer. That I've used to a limited degree, due to searching for parts in the correct file format is mind-numbing! I have globally sourced fittings; USA, UK, ASIA. As a matter of fact, the searchlights I got from this Model Boat Shop were 3D printed, and I was able to fit 5mm LEDs into them. I'd like to get a couple more and put some superbright 12v LED drone lamps in them for use on my 35" towboat. Many deck fittings are handmade when possible, the cleats and fairleads are from Cornwall Boats, UK. (Very reasonable & diverse source, if you didn't already know.) I try to keep wood natural when detail allows it, as I never have enjoyed painting over natural grain. Her decks are covered with 1/16" scribed basswood sheathing from earthandtree.com, which is normally used for wainscoting dollhouse walls. All my boats that have wood decks are covered with scribed sheathing; I feel it makes 'em look "sexy". Believe it or not, the idea for wainscoting came from finding 3/16" at Hobby Lobby's dollhouse department. A couple of feet x 3.5" was about $16, so I found a less expensive source that also had more selections (earthandtree.com) The rail stanchions are 3/16" square dowels with 2 corners rounded over on the Dremel router table. Leaving their base square, I fit a square peg into a round hole with no glue to facilitate removal, and also for ease of replacing broken ones, which is inevitable. The rail is 1/16" brass rod that also is readily removable. The stern rail is stationary on the lower half, and the chain & wire stanchions are removable for towing ops. The deck coamings and knuckle are African mahogany strips, other mahogany accents came from leftovers of a prior build. I also try on all my boats, to incorporate vintage leftover scribed sheathing salvaged from my late Father's builds, so I know he's got a part in my builds. Note-the raised deck section between the aft ladder trunk and towing bit is actually a laminated deckhouse he made for the Frigate Essex. Unfortunately, he was unable to build that kit due to Alzheimer's disease in his latter years. (I blame that mostly on the hazardous fumes from the airplane "dope" & glue he used when building RC planes in the 60s & 70s.) I use polyurethane instead of resin due to COPD, 37 yrs of smoking, I quit 2.5 yrs ago. The driveline consists of: 775 Johnson DC main (3500 RPM@12V), Harbor Models 4mm x 14" shaft w/brass stuffing box, Raboesch 75mm 5-blade brass wheel (not OEM), 5mm U-joint couplers, Dimart 320A fan-cooled ESC. Handmade wooden teardrop rudder on a 3/8" sternpost, 1/4" tiller arm steered by a Halcion sail winch servo and cable system. Flysky 6 channel. The nav lights and other illumination are Lighthouse 9v LEDs, also a GoolRC Receiver controlled flashing blue Law Enforcement light. Obviously, I put the cart before the horse and completed the topsides and below deck before finishing the outer hull, but the Wx and season change dictated such. Can't wait for Spring!
Hi AllenA, LOL! I think you're referring to my post "Local Boatshow" in the Boat Harbour section. Doesn't matter. Happy to read that I'm perfectly fine! I'm just new here and have no idea how active this forum is. I happened to stumble over this forum while searching RC boat photo's on the web, and thought: Well why not drop a question here. (not knowing at that time that I would spend half the afternoon posting pics of my own fleet...and I haven't even finished yet...) Back on topic: I'm curious to see what advise I get over here regarding the Fairplay V. I might even keep up a build blog over here. I like the classic - almost yacht like - sheerline and superstructure. And this model is compared to the Banckert, Bugsier, Kalle or Torben tugs slightly wider and heavier; which will give this tug just a bit bigger wavepattern...
Hi Norm, All the weapons, boats and other 'hangers-on decks' are Humbrol colour Matt Sea Grey # 27, Revel approximate Matt Mouse Grey (Mausgrau) # 47. Don't know what paint type you use but I have several conversion charts so let me know and I'll see if I can find an equivalent. Flight deck is Matt U.S. Light (!) Green # 117, which is actually not so light, more of a Sea Grey-green. Arrester wires: On the Ark there are 8 ! According to my plan- #1 33.5m from the edge of the roll down, #2 6.6m from #1 #3 6.6m from #2 #4 7.33m from #3 #5 7.33m from #4 #6 6.95m from #5 #7 5.64 from #6 #8 5.26 from #7 No guarantee for accuracy!! Or even if 'Lusty' was the same but it's an indication. 😉 Your build is looking good 👍 I'm wondering if you are taking all this trouble why don't you go the 'whole hog' and bring her to life😉 Finish the hull and give her some motors 😊 No, I'm not in UK, I'm in Munich where I've been for the last 32 years, Tempus fugit😲, hence my forum name 😉 Cheers Doug 😎
The gun deck isn't modeled. I was building a model intended to sail in open water and didn't want to deal with open gun ports, hatches, etc. After glassing the hull, she got beams for the spar deck installed. 3/4" x 3/4", they're probably a bit more than was needed. Tubes were installed for 5/16" stainless threaded rods that would hold her external ballast on. The forward one will be disguised as her galley stovepipe, the aft one is hidden under the cabin skylight. The ballast is a 2" i.d. PVC pipe about 4 feet long, filled with lead bird-shot, and weighing some 42 pounds. With that much done, I took her to the creek to see her float, but I forgot the rods. A few days later I took her out again, remembering the rods, and put her lower masts in her. Now baptized, I applied the moldings and trim on her stern, and built up her enclosed head. Her gunport were molded in resin in the closed position with the guns clamped in the openings and a tampion in the muzzles. These were epoxied into gunports cut from the outer layer of glass and wood battens, leaving the matting in place as a backer. Then she got some paint, mainly because I was getting tired of her looking like a barkless log. The bottom was painted with copper paint, but three rolls of 1/2" wide peel-n-stick tape had just arrived and I started into coppering her bottom right off. Copper plates are nailed on with copper nails with counter-sunk heads through pre-punched holes in the copper sheets. The are FLAT with with a little hollow where they're driven in just beyond flush with the surface. They are NOT round headed nor look like rivets as so many models insist are doing. I pressed an impression of the nails into the face of each plate. Installing them pushes this dent back out and leaves a little circle that looks as it should. It took about a week to do one side, and I took a break to make the tops for the lower masts, then continued onto coppering the other side. It was bright and beautiful when finished, but it wouldn't stay that way. Copper doesn't turn green when submerged, any copper coin will show you it turns brown. I wanted her bottom to brown somewhat, but not too much, and I figured to let that happen naturally. When it got where I wanted it, I'd clear-coat it to lock it in. Two yards of Dupont Supplex cloth was ordered to make her sails. This is the stuff SC&H used on their square-rigger kits and it's great for making sails. Being a nylon, you cut it with a hot-knife, and use a pointed tip in a soldering iron to make grommets. I drew on the panel seams with a .03 marker as even the finest stitching is over scale even at 1:36. Top-cloths, corner reinforces, reef bands, etc, are all cut from the same cloth and glued on with fabric adhesive. The only sewing was of the bolt-ropes. These are done by hand much the way real ones are - I've sewn a few miles of real bolt ropes in my time. There's really no substitute for this if you want a functional scale appearing sail. A machine can't sew it properly, in the right position, or securely.
Hi When you started the build I saw that you had a good strong flat board and had supported the keel in several places. It looked as though it was all going well until you started to skin the hull with very heavy balsa(?). When applying skins the hull does need to be supported at all times and skins applied equally to both sides at the same time. Wood has a nasty habit of shrinking as it dries, and doing equal planking on both sides helps compensate. When we built the Titanic and Olympic the hulls were built upside down and remained on the build board until all planking was complete. We used 4mm balsa sheets. and covered inside and out with fibreglass matting and cloth. To use this method you need to extend each former so that the hull is level to the board with a gap at the bottom when you have finished. Couple of pics attached may help explain. Good luck with the rebuild Dave
There is a white metal ‘ring’ supplied in the kit for the Kent Clearview screen but it is too large and doesn’t look particularly ‘scale’. So after some research on the web and some help from other forum members I found enough information to make one from scratch. The outer ring was made from a narrow section of pvc pipe that I had to hand and this was cut to length in a mitre block and then sanded down to the right thickness on some abrasive paper and then sprayed matt black. I didn’t use the perspex screen supplied in the kit as the hole was too large but the small circular cut-out piece was the right diameter to fit into the ring that I made, the new screen was cut from a new piece of perspex sheet and a hole drilled through the centre to locate the rotating part of the screen. The parts were assembled onto the new screen using canopy glue applied very sparingly with a dressmaking pin. The motor drive assembly on the inside of the screen and the black triangular part that sits on the outside of the screen were made from some black plasticard and these parts were also fixed in place with canopy glue. I used a brass panel pin with the head filed down and painted black for the central bearing of the screen but when I applied a very small amount of canopy glue to fix it capillary action unexpectedly drew the glue between the two ‘panes’ of perspex 😡 Not what I wanted to happen but I decided to leave it to dry to it’s clear state and then assess the situation. Fortunately the glue is not too conspicuous to be much of a concern but it is nevertheless an unwanted blemish that I will have to accept 😭 The finished piece was then glued into the wheelhouse with a few dots of canopy glue and looks quite good as long as you don’t look too closely 😎
If you put a question out there, you'll get an answer. At least you will from me if I know about it and I know about paint. Why on earth do you say acrylic can be put over anything UNLIKE cellulose or enamel. Cellulose maybe, but enamel? You can put enamel over anything. I can even get cellulose over almost anything with my spray gun, but I know how to mist it on. I suggested enamel because it is so completely harmless. Cellulose, apart from mixed Halfords and Zero Paints is no longer available. Acrylic as you know can react even with itself. It doesn't have good pigments and doesn't cover well. Enamel does. I was well aware that the original post was from a new member, so I figured he deserved a straight answer. Not everyone wants a matt or even a satin finish on a model boat if it isn't a Warship or a service vessel. Would you put satin varnish on a Greavette or a Chris Craft, matt paint on a model of a luxury yacht of any age? Of course not. This nonsense about scale effect is just that....nonsense. A shine's a shine whether smaller or larger, otherwise where do you stop? Martin
Hi, very surprised you haven't had a reply on this topic. I'm only just going through topics and you've probably finished it by now! I would use lime (basswood) and as deck panks are usually about 3 ins. I would get some 1/4" wide in 1/12th scale lime and use black card or ebonised wood veneer (black stuff) for the caulking. About a milimetre thick is enough for the deck planks. Then I would give it a matt finish with (as Colin has just advised me) a coat or two of Ronseal matt polyurethane varnish, the oil based one. Most model shops will have basswood, especially those dealing with model ships. I also find my local "serious" doll house shop a good supplier of modelling timbers. Cheers, Martin
Hi all, I need to use a matt finish on my model of "Vanity" as she would have had scrubbed teak decks, in fact she still did when I lived on her! Used to leak like a basket, playing a gamalan orchestra in the many pots I had under the drips. So....can anyone recommend a nice reliably matt waterproof finish for the decks on the model. Cheers, Martin
Hi chugalone 100 Welcome to the site. You can fibreglass with different types of resin and cloth. If you are making and casting a fibreglass hull use fibreglass matting but to cover a hull lightweight fibreglass cloth is best. This is the type shown in the suggested video. Resin can be epoxy or polyester based but the latter is generally cheaper and in my opinion is easier to use and doesn't require thinning with alcohol. It is sold as layup resin and is supplied with hardener. Do follow the instructions re quantity of each part and mix thoroughly. If you are using epoxy Iso Propyl Alcohol is the type to use and is clear. The video shows using a brush to apply the resin and whilst this is OK it will give a very thick and heavy coating. I use the brush to apply and then a credit card sized piece of plasticard to spread the resin over and into the surface of the cloth resulting in an almost opaque finish with the weave showing through. You do need to have a good surface to work with as any imperfections will show when the resin hardens. Once dry give a light sanding all over to remove any imperfections and fill any holes with car body filler and sand smooth. I then apply a very thin top coat of the resin using a brush. When dry use wet and dry to sand and if necessary apply further thin coats until you have the finish you require. I have a local supplier and if you visit the site http://www.resin-supplies.co.uk/product.htm all the resins/cloths etc are listed. Using Google should bring up a local supplier. you do need to follow the safety instructions to protect yourself and wear appropriate protection for your hands, eyes and breathing, it is also best to apply in a well ventilated area and not on a cold day. The end result will be well worth the effort to keep your tug waterproof. You could also paint the resin over thye inside of the hull to protect the wood from any water that doeos find its way inside. Dave
Hi Mark Unless you are looking exactly at the side of the model with your eyes aligned to the level of the line it will look wrong because the spray rail is raised from the hull. If you remember the old type of analogue volt meter, the better ones used to have a mirror on the scale to ensure you were viewing from the correct angle. I suspect now that we have aired the matter many will notice this on model boats. I suppose we are all wishing to achieve the correct finish to our models and yes we are sometimes too exacting. Dave
