Knightswood model boat club

    After building a 1/12 scale semi exact Watson 47ft lifeboat and two other boats I decided to build an exact

  1/12 scale  Liverpool twin screw lifeboat, again my friend MrJ.White  was able to provide me with a full set of drawings, lines and offsets, scantlings,and general views, plan, side elevations, plus all electrics, water fuel lines etc.

    The line drawings were very smudged due to the age, so I set about producing my own set of drawings working from the offsets table, I also drew onto these the water line and deck positions, as well as the position of the inner stringers.

   Now I could start, the wood I used was sorted out, this was to be pine for the keel,stem, sternpost (this was from an old church pew book shelf ). The frames were to be made from cedar wood (ex ceiling boards) and due to size of the frames 1/32 ply for strengthening, below deck level.

  The cuddy was to be from mahogany frames,stringers, deck plate, planking inner layer tanganika outer layer from mahogany.Decks from 1/16 ply overlaid with pine strips.

  All metal fittings was to be from brass strip, rod, plate.

Now I was ready to start, a building board was made from white contiboard and a mahogany strip as I was to build right way up.

  All this was some 5years ago and still not built two many other things have been made since this one.

  All pictures will enlarge if you roll your mouse over the picture, hope this is suitable.

  The base board was made from white contiboard as it could be drawn on with ease for setting out the frames, the base strip was screwed to another piece (not seen) the two end pcs, are set back so that the stem and stern can be screwed on and the keel screwed to the base strip (see photo of keel in place).
      KEEL       This is made from an old pew shelf,
tracings where made of all the parts on my drawings, these were
then used to mark out the the 55 parts,then to cutout,all parts
Were checked for square and then glued up and held with clamps.
Once dry the  keel was sanded and then screwed to the base
Strip, and marked out for the frames.

    FRAMES     The frames  are made in 1/8 thick cedar wood,a 1/32 backing piece below the deck level, 1st. Step was to draw out the frames from the table of offsets, this included the deck level and position of all deck stringers,then the position of the lower cutouts.the next stage was to make each frame from pieces of 1/8 x 5/8 wood, these were laid over each frame drawing(clear film was laid over drawing to prevent glue sticking to drawing) so that all the frame was covered, the pieces were then edge glued together,and left to dry,a piece of 1/32 ply was then cut to cover the frame from above deck level and outside frame.The photo
Shows the frame cut out to deck level,outside cut then all internal cutouts made,all the                                                  cutting was done on a scrollsaw with a fine blade

   SETTING UP THE FRAMES       Once all the frames were cut and checked against the drawings and cleaned up ,the frame positions were marked on the building board and the keel,then the required slots cut in the keel and each frame tried in place for a good fit, once happy with all this the frames were glued into place using a set square on both side to ensure that each frame was square to the keel,the deck stringers were next put in and glued .

  Once all the frames and deck beams were in ,the sub deck was fitted 1/16 ply,this was in four pieces due to having to fit the side around the frames, once in place the frames in the centre were removed, and the gunwhales put in . The cabin base plate was then cut out and fitted(the shape was taken off the drawings for this )  




                                                                                   Sub deck in, and cabin base in place, just about ready                                                                                     for planking just the frames to sand to shape







      CUDDY/ENGINE ROOM COVER      This was started by making the base plate to match that on the deck,this was followed by open end frame,a foam plug was then made to fit, and the frame work built up over this ,all to the drawings and scantlings, the idea being that once planked  the foam can be removed, the planking is two layers as the hull , but in mahogany,

    Once all ribs were in place planking can be started.

        In between this work I started to make some of the fittings these are all in brass and are turned all filed up  and soldered where required, the binacle is in two pieces and will have a compass in gimbles , the two large portholes do actually open ,it is intended to operate the rudder by a servo with pulley to a twin pulley on the streeing shaft with a crown and pinion at the rudder end please see gallery for photos of the fittings.

      Hope this makes sense  as this was made up about 5years ago but only written up now from memory
