I'd confirm what Ron says above. A slight warp, like yours, is paradoxically harder to shift than a biggy. I had a terrible warp in an old hull, but after making diagonal strutting and regluing the skins to a point a bit MORE than the warp in reverse, it sprung back to a perfect shape, but that roof is slight and so steam is the way. You can also use hat water or even just water, but, as Ron says, you'll need to twist it in the opposite direction and keep it there. A cheap and cheerful wooden frame is the answer, then either steam or dunk the whole lot in your garden (or somebody else's ) water butt. That's how I put the sheer AND deck camber on the 1.6mm decks of my yacht model. Worked a treat. left them to soak for half an hour and then dry on a hot sunny day, naturally. I now have a flat ply deck which has the curve of the sheer AND the athwartships camber all at once. I also notice that the framework under the roof sheet isn't complete. If you were to complete that while holding the roof in an unwarped position, glue up and let it set hard you could also find it will straighten up. Failing all this, making a brand new one from a bit of 1.5mm ply and some 3mm for a frame will be just as quick. Ah, it's our pirate friend. Hello Bryan. Hadn't twigged it was your Seaplane Tender! It deserves repair rather than replacement, I reckon. Cheers, Martin
Scratch built at 12th scale from pictures and profiles of the internet. The boat was originally built in Sweden a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet Speed: 40 knots (74 km/h) Draught: 0.8 m (2 ft 7 in) Length: 15.9 m (52 ft) Overall; 14.9 (48') Complement: 3 (two officers and one engineer); Up to 21 amphibious troops with full equipment Armament: 3 × Browning M2HB machine guns; 1 × Mk 19 grenade launcher; 4 naval mines or 6 depth charges . The Model I was attracted to this boat due to its great performance and maneuverability, this was mainly due to the use of twin water jets as the main propulsion, this is a trade off with efficiency. So my start point was to collect as much information as possible about the boat this involved collecting pictures and profiles of the craft from various sources. http://www.dockstavarvet.se/products/combat-and-patrol-boats... Eventually I found some plans of sort :- http://laurell.today/boats/combat/plans.html My Dad was a boat builder in the days of wooden yachts, and had showed me how to make plans and frames from a line drawing. I went about this first by creating a prototype about 24 in long out of light ply. I then created full size plans of the model to be made. Pictures of small prototype finally painted plain green. The Main model Used my computer to print out the frames onto paper, cut them out and used them as templates for the ply ribs. The construction was simple chine style, with 1.5 mm ply. I tried to build jet drives but failed to produce a effective unit. So reverted to propshafts which worked out well with better control and the boat can spin on it own axis by putting one engine in reverse the other in forward and adjusting the twin rudders. That it for now, hope it was of some interest
PT 109 was one of the hundreds of motor torpedo boats (PT) of the PT 103 class completed between 1942 and 1945 by Elco Naval Division of Electric Boat Company at Bayonne, New Jersey. The Elco boats were the largest in size of the three types of PT boats built for U.S. use during World War II. Wooden-hulled, 80 feet long with a 20-foot, 8-inch beam, the Elco PT boats had three 12-cylinder Packard gasoline engines generating a total of 4,500 horsepower for a designed speed of 41 knots. With accommodations for 3 officers and 14 men, the crew varied from 12 to 14. Its full-load displacement was 56 tons. Early Elco boats had two 20mm guns, four .50-caliber machine guns, and two or four 21-inch torpedo tubes. Some of them carried depth charges or mine racks. Later boats mounted one 40mm gun and four torpedo launching racks. Many boats received ad-hoc refits at advanced bases, mounting such light guns as Army Air Forces 37mm aircraft guns and even Japanese 23mm guns. Some PTs later received rocket launchers. This Proboat PT 109 model was brought in 2013 for £100 these boats are rare now, This one had a few faults with the propshafts they were bent and noisy both were replaced, with quality 4mm shafts, motors twin 600s were also replaced by Graupner versions along with mounts and couplings, basically all the running gear, also two ESCs by Aquapower were added and a 2.4G RC system.
Hi all I have just spoken to Brian at Mobile Marine and he advised the term was based on a very old English name for belaying pins. Basically its a wooden plank with holes for the belaying pins and fastened in a raised position to the deck. The shrouds are wrapped in a figure of eight round the belaying pins which in an emergency can be knocked out to release. They are used on the davit fixings, not the mast. I have small hooks on the shrouds to the bulwarks and on the fore mast fitting. My model requires the top cabin to be removable so I have made a fixing out of wire that can be quickly released from the white metal fitting on both sides.
Have moved on to the deck furniture and equipment, including the funnel. Most of it can be made from the usual assortment of scrap materials and odd and ends. Decided to start on the funnel. Planned to make up a wooden replica and wrap a thin styrene sheet around it, finally inserting styrene formers into the shell, gluing them into place. Made the replica up from scrap wood blocks and shaped it into the correct shape. The outcome looked so good was tempted to use as final as making funnels seems quite a challenge. Anyway proceeded to plan and shape thin styrene sheet around the replica, using a heat gun to overcome the memory. Once this was done, fitted shaped styrene internal formers to hold the styrene to the correct shape and glued with adhesive. After the styrene glue had dried and the excess material trimmed, now had two usable funnels - wood and styrene. The wood version is nominally smaller and fits slightly better, so decided to use it. The Teakwood was originally operated by the J I Jacobs Company, which had a buff funnel with a black cap as markings. Stumbled across a picture of the vessel when she was chartered to the British India Steam Navigation Co. Evidently BI usually painted chartered vessels in their livery. Although the picture does not show the traditional and attractive BISNCo white hull cheat line, it does show the funnel markings. These are black with two narrowly separated white bands. Rather preferred this scheme so adopted it. The picture was taken in the mid 1960s and it also shows a pristine looking ship, my worries about the model looking unsoiled seem groundless. One of the pictures shows a strip that extends back from the wheelhouse almost to the funnel - this is a support for the awnings that fit over the bridge wings.

Fran Oakey designed the Griffon 600 as a wooden model. Originally called the MM600 it used 2mm liteply without any lightning holes. It is heavier than the Depron version but will operate in rougher water and higher wind speeds. Takes the knocks better too.
Hi Kipper. Thanks for the link, I had already looked at the site and unfortunately could not visit on the 27th May for their regular lakeside meeting to make contact with club members. However I had previously paid a visit to the lake on Sunday 21st May expecting to see a few boats on the lake on a what was a gloriously sunny afternoon and found not a single boat but plenty of wildfowl and the lake clogged with weed and leaves. It's a nice big stretch of water with plenty of landing stages around the shoreline and on the wooden bridge that separates the pleasure boating lake from the model boating lake but the amount of weed and detritus would make me wary of making a maiden voyage there. By contrast, I visited the lake at Verulam Park St Albans a week earlier and, although not as big, had little or no weed, but a few alarmingly large branches were being thrown into the water by dog walkers who were encouraging their pets to retrieve them, but were ultimately abandoned. Sadly no boats were being sailed there at the time so I could not make any inquiries with their owners. The first 3 pictures are Stanborough and the last 3 are St Albans. I think I know which I prefer but I would still like to have the view of others who use these lakes regularly. All responses welcome....please ! Thanks. Rob.
I have been puzzled by conflicting statements on the web, some stating that adding resin and fibreglass will strengthen wooden construction, and others stating that it will not. For my own understanding I did some tests, which others may find interesting. These are not by any means scientific, and meant only as a guide for me in model construction. The results show that coating balsa with resin and fibreglass cloth does strengthen it. For those who want to see more detail, these are the results. Three separate strips of balsa, each 18" long by 1.5" wide were cut from a single sheet 36" long by 3" wide, 3/32" (2.4mm) thick. Each strip was placed on top of two supports 10" apart. A load was applied in increments to the centre of the span. After testing each strip in its uncoated condition, each one was coated with Deluxe Materials Eze-Kote resin, according to the maker's instructions, and a layer of fibreglass cloth applied on each side. The cloth was a piece I had spare so I don't know what weight it was, but I estimate between 1 and 1.5 oz per sq yd. After coating each strip was tested again. The results are shown in the chart. The lower the deflection when loaded, the stronger the strip. Although all strips were cut from one sheet, strip 3 was clearly stiffer and stronger than the other two in its uncoated state. It benefited least from the addition of the fibreglass. Strips 1 and 2 showed a significant increase in strength.
Hello, I recommend grinding the whole body with fine sanding paper, then take the "LORD NELSON" pore filler and then re-grind it again. Subsequently, the final lacquer of the best brand. I have been treated like a wooden boat DIVA and already for 6 years on the water without any problems. What happened to you is that you used a bad lacquer that does not resist water. Two-component epoxy lacquers are also good for large yachts. I'm sending a link to the Czech site where the varnishes are designed for ship modellers. Just use the Gogle translator and the same merchandise you can get at the shop. Or on EBay. https://www.modelylodi.cz/Laky-a-plnice-c11_86_2.htm😉
I had previously adapted the mast with lighting and fixing studs and so it’s ready to be fitted to the wheelhouse roof, but I decided to add some rigging detail in the process. Along with some other items, I had previously bought some threaded brass ’eyes’ and wooden rigging blocks by mail order from RB models in Poland. Very good prices and remarkably quick delivery from overseas. http://www.rbmodel.com I drilled the horizontal bar of the mast to take a couple of small brass eyes, and bent the lower part of the exposed thread back at an angle, onto these I fitted some wooden rigging blocks with brass sheaves which I had previously stained mahogany and lacquered. Another slightly larger eye was fitted to the centre of the mast and another to the wheelhouse roof for the forward stay rope, I used some thin white elasticated thread that I found in my local Hobbycraft store for all the rigging. The stay rope end were finished with small brass hooks formed from some thin brass wire and secured with some small diameter heat shrink tubing, I think this makes for a much neater look than just tied knots. The top rigging ropes were made in the same way. The completed mast was then bolted down through the wheelhouse roof on the threaded studs and the two lighting wires passed through separate holes in the roof. This should allow me to detach the mast and fold it down for transport if necessary. The lower end of the ropes from the rigging blocks were formed into a loop with a spot of superglue to fix them and then some small white heat shrink tube used to cover the joints. The loops fit neatly over the cleats on the cabin roof so that they can easily be released. I’m hoping that being elasticated all the rigging will stay taut and remain presentable 😁 I must remember to order some ensigns flags from 'Mike Alsop Scale Flags' for a finishing feature as recommended by pmdevlin in an earlier blog post 👍
