As the stern needed the most reshaping, decided to tackle it first. Made up a wooden insert to reflect the correct deck stern contour and glued it in between the deck supports. This would give the stern be the correct shape and length. Once that was positioned pulled the hull up tight to the supports. As the stern is approached the sharper profile of the Teakwood requires the hull sides to be pulled firmly inwards and the transom be vertical. Decided this was not going to epoxy and stay in place satisfactorily once the strain was released, so cut a series of vertical slots in the rear hull to allow it relax and squeeze it together. One slot has to be quite deep, otherwise the lower hull will crack as it will not relax sufficiently. Used the Dremel cutting disc for this. The slots need to be quite generous as the the hull has to be pulled in some distance. Once this was all epoxied in place, wrapped “cling film” around the rear of the hull and poured liquid fibreglass resin around the slots and under the insert to bond everything together. Worked this onto all the vertical and horizontal surfaces as it set. The stern is now good and rigid. The attached pictures show the new stern profile and slots. The first pictures are “as is” to illustrate the process. Further work was also needed to true up the bulwarks and disguise the slots. This mutilation may seem a brutal way of getting the hull shape correct, but had tried all kinds of pulling and squeezing of the hull, none of which held in place after the clamps were released. Once the cosmetic aspects of the stern rework were complete, established the correct location for the rudder post and fitted it. The major stern work is now finished.
[Score: 9/10] 60"/7600g Schooner - Comments: Scratch built with mahogany planks on the club's mould. Glass cloth and fibreglass inside and protected with G4 polyurethane resin all over. Uses a sail winch (Hitec) and travelling dolly for the two main sails and a separate arm servo for the foresails. Standard servo for the rudder. Power is from a 6.6v 1000mA LiFe battery. Taranis Tx using two sticks with the sail servos connected via an internal mixer to one stick. Ballast is fixed to the keel with two studs which extend into the hull where a steel bar is attached between both and acts as a carrying handle.
Had this Fortune 612 delivered through the post while in Hospital and when unpacked found that the keel had broken at the base. Any advice please as to a suitable method of repair as I can't seem to find a replacement on 'tinternet'. Fibreglass comes to mind???
Try polishing the varnish once it is good and hard. Use a good polishing compound as used on cars and plenty of water don't use an angle grinder they're too fast and will burn the varnish.You might be able to sort out something using a Dremel type tool, but again not too fast, to get into the smaller spaces on deck etc. It is possible to do it by hand but takes longer.Done properly you get a finish like glass. A lot of car painters rub down wet first with very fine paper then do the polishing. Go to a car painters and watch them and ask them to show you what they use.Really educational. You could learn lots. Cheers John .
Hi Bellman My Club sail several similar boats as well as an Ibex. They are all fitted with detachable keels which are fitted prior to sailing but can be removed for transportation and display. Our sailing waters are large and exposed and without the keels the models would not be able to be sailed. On the water the keels can not be seen. I tried a long keel on my Cariad and it was not a success as the keel tended to keep the model in a straight line. I now use a detachable bulb keel. The amount of lead will depend on your model and its overall weight. The bulb keels are a fibreglass moulding that we fill with lead to bring the model to waterline after inserting fore and aft threaded rod into the bulb. You will need to have holes in the keel to let the rods thro and long enough to be above the waterline. I fit a plastic tube and wood support inside. A washer and nut hold the keel in place. Before filling with Resin weigh the resin in the tin and remove that amount of lead from the bulb. Once set I use silicon to make a good seal between the bulb and hull and which remains attached to the bulb. Attached are pics of my Cariad.
Hi Welcome to the site If it's plasticard using fibreglass or paint stripper may cause it to melt. What is your intention for the hull? Can you post a pic? If the hull paint is sound you may be able to rub it down with fine wire wool and overpaint.
a job lot i have acquired contains a boat that has been constructed out of plasticard and painted red, whats the best way to recover the plasticard hull, d o I strip it or just rub the paint down cover it with fibre glass😡? (never come across the card build before) *** Thanks will try the paint job***
Both Fairmile D boats 1/24 scale and are scratch built. They have both been about 6 years in operation. MGB623 is an MGB, flying the Norwegian flag and belongs to a good friend. Mine is MTB741. It is powered by 2 Graupner Speed 700 12V motors with NiMH batteries. The 6 pdrs and 20mm guns can rotate. It has a balsa planked hull and fibreglass skin. Decks and superstructure are also balsa. Guns are from tinplate and brass.
If I start a model using a fibreglass hull the first thing I do is bolt it down to a building board, just as RHBaker has done. Access to the bottom is not needed until painting, so the model can be worked on 'keel down'. I have two end boards that can be screwed on to the building board, and these allow me to lay the hull on its side, or upside down, and be stable, if I need to work on it that way. When the hull is ready for painting the holes in the hull are filled and sanded.
Hi Novagsio The only place that my help you out is Westbourne model.co.uk, but, they sell to full kit. May sell the fittings kit. The original handrails from my Precedent fibreglass hull are total rubbish, but, I only got with my second hand unfinished boat the air scoops. So I plan on making the hand bow rail and windscreen. My boat is in the BUILD BLOGS on the site. Canabus
Good weekend of progress has seen the hull glass clothing completed and has now had 2 coats of resin. Will get a 3rd and final coat after last stabilzer is fitted before final sanding, priming and painting (once motors and propshafts have been fitted). Have also made good progress on the cabin superstructure which has now started to get this "Solent" closer to the eventual finish line! Not much more can be done this week as starting Nights tonight, sometime good to have a break though!
After a week away in Lanzarote, have had a couple of days to get some work done. Left side of hull is now fully sheeted, gaps filled and awaiting final sanding and glass clothing. Decided to get ahead of myself and have fitted all the deck pieces and the cabin deck formers. The inside of the hull has had a second coat of epoxy resin and will get a couple of coats of yaht varnish once the final pieces of internal wood parts have been fitted to include battery tray, motor mounts, prop shafts, servo rail, ESC tray, receiver tray, speaker/engine sound module tray. Up at the bow have fitted the wood for the on/off switch, sanded, sealed and primed the bow deck before adding a couple of the detail parts.
Hi Dave, I'm sure that Bondaglass is excellent. Unfortunately they don't have a distributor in Australia🤔 Shipping cost quoted to Germany is 11.95 which doubles the price of a can. To Austria, just down the road from me, they quote 33 pounds!! For Australia the info is 'Contact us'! I checked that Deluxe materials have outlets in Australia and found two 😉 Cheers Doug 😎 PS lovely woodwork, would be shame to hide it 😆
