Model Maker: Volume 3, Issue 26 – January 1953

yi | f ical IJ year our own Model Yacht Trophy will be offered for the 36in. Restricted Class. Moreover, with kitting in prospect, Arthur Mullett, already had in stock enough material and fittings to equip nearly a hundred boats. The schedule of materials shows what can _ be obtained and offers an opportunity to get sailing at the minimum of expense. Construction of Hull Like all hard chine boats the main hull parts comprise a skin of four pieces of sheet, two for the bottom and two for the sides. A backbone the whole length of the hull joins stem and transom and these are erected upside down on moulds as fully detailed on the second sheet of drawings, which provides step-by-step illus- trated building instructions. The backbone itsélf is skilfully designed so that it is in effect three thicknesses of wood— the two outside sandwiching a third which includes the keel and skeg. Brass pins and screws should be used throughout construction. Durofix or other waterproof adhesive can be employed, or better still one of the gap filling resin glues, embodying glue and hardener in two separate bottles. The deck comprises two halves and a central kingplank. Before fixing this be sure that all The original “Lancet” in its Festival of Britain paint with @ real gold leaf line decorating the hull—clearer in other pictures. Her trim lines should make a wide appeal ap ie boat was designed by Tommy Lance when the yachting section of Arthur Mullett was still Lance & Mullett, with a view to producing a simple class racing yacht that could be kitted, and that would—in spite of its simplicity—be good enough to show a fairly places where-screw eyes, horses and so on come are suitably reinforced underneath by gluing in squares of scrap wood. Also see that deck beam is reinforced, where mast is to be stepped. Only other item to remember is rudder tube which must also be located before decking. Ballast for keel is in the form of two halfround bulbs of lead. These can be cast by Arthur Mullett if desired, or patterns are included for builders’ own casting. Weight frequent transom to the best of company. The prototype, finished in white enamel with a gold line, was accepted for display at the Festival of Britain as typical of the best of British workmanship in its class. Such acceptances really meant something as the number of items submitted was many times greater than could be shown. This prototype is the subject of most of our illustrations. The untimely descent of purchase tax upon the model world caused the kitting project to be shelved, though a number of plans and wood packs were sold, and enough models built and raced to more than justify the designer’s belief in the soundness of the model. We were delighted, therefore, when Arthur Mullett suggested we might like to take over the design for MopEL MAKER, particularly as this . should be approximately 7 lbs. (or 34]bs. each half). They may be screwed on to keel as illustrated. Rudder is attached to brass tube suitably filed away as shown and is balanced on small bracket. It is important that there should be no binding here, but perfect freedom of movement. Do NOT oil this as water will cause oil to become sticky and defeat its object! Any good enamel applied over its appropriate undercoat can be used to finish the hull. Hard chine boats look best if finished in one— 12 36IN. RESTRICTED CLASS BY SHARPIE TOMMY LANCE preferably light—colour above the water and decorated by a thin line as in our prototype. The conventional “Boot top” of round hull boats does not look so well on the straight lines of our boat, though the lower part of the hull can be painted in some dark and serviceable shade, nor is a varnished finish recommended, ‘ particularly to novice builders who may be only too anxious to cover up imperfections of building which will not ultimately affect performance. . ; , ; Mast and Boom These should be made from spruce. If extreme portability is desired it may be considered a good idea to make mast in two halves, joining by a brass ferrule as in a fishing rod. It adds little to the weight and reduces whip of mast very little but adds a lot of convenience. These can be finished to square and rectangular sections respectively. If fractionally improved performance is desired the mast may be finished to a pear shape for streamlining— having the foot, of course, round to fit mast step on deck. This, however, makes a two-piece mast more tricky and means that it will probably have to be kept in one piece. Finished mast and boom should be varnished with a good marine varnish.. Shroud lines and other fittings are very simple and within the skill of a complete novice. Deck Fittings Simple screw eyes and jib horses should be fitted where indicated. The Braine quadrant can be cut out of sheet brass, or bought ready made, and soldered to the top of the rudder protruding from the deck. Those who like their brass glittering without effort should paint all brass with a transparent lacquer after first polishing it. One application will last months. Transparent nail varnish will do the trick if necessary. Sails Novices are recommended to buy a set of sails as Offered by Arthur Mullett. These are very cheap as they are not of Union Silk, as used on These detail pictures will prove of value to the builder in showing how a “ship-shape” appearance can be obtained without vast expenditure on fittings. Note that booms are rectangular—this is a great convenience when calibrating them, as some yachtsmen do, to obtain identical re-trims when required Sam ne SMEET 1-OF 2 f { ‘LANCET. 36’ REST.
