      Hi everyone
      Ive taken the plunge and decided to make my first model boat, ive been at it for a month or so. Thoroughly enjoyable and addictive, alot more goes into it than meets the eye.
      Iam making a FV Northwestern from Deadliest Catch, i love the elegant old girl and havent seen too many try and make her, so hopefully ill do her justice.

      Total Scratch build

      I am a complete novice so some methods may seem bizarre, started out by carving her hull out of high density foam, which was reasonably fast and productive. having already made myself full sized 1:32 plans. I struggled for a while to adequately seal the foam for future fibregalss layup, but i got there in the end with plain old pollyfilla yes i was surprised how well it worked, it was easily sandable and took to the foam well.
      So my journey onwards full of self discovery lol, alot of materials id never used before, the next was fibreglass, which was reasonably priced, my technique however for a first time was pretty good, the odd tear in the gel coat where i added the matting, however the resin and strength was all good.
      Hull is ready for deck and rib fit outs, wheelhouse is formed, sadly the cold weather has halted recent progress, however nothing is lost and i have whipped up 100 odd pot frames.

          So i did my first water test last night, watertight and is very well balanced. However im going to need an awful lot of weight/ballast.

          Iam planning to include a fair bit of hardware which shall hopefully bring the weight up. This will include 2 12v lead acid batteries in parrallel, feeding the motor and a large diesel sound generator…….6V lead acid in the bow for bow thruster, all the lights, bilge pump, radars and working crane mechanism.
          Hopefully and with some good planning ill be able to fit all this in. Its not just about hiding it under the deck as i want an area accessible to incorporate maybe ballast tanks as this might help my dilemma.

           

          I have a selection of motors, this is because ive been given some contradicting information i may have to trial and error it. There is a Johnsson 600 which some claim will be too fast..i think it might be the best option as the northwestern model will be very heavy and will need power, in real life she does 11-14 knots which is pretty decent. The other engines are a 540 6:1 which ive been advised as giving better scale speed, i have my concerns as scale speed is diffult to get right, at that size the water is like soup as opposed to water therfore more power is needed, which maybe makes it look a bit faster. The last one is a graupner 600 that is 8.5 volts so id need to run it off of a 6v battery. A friend has a lifeboat which is a bit shorter than my model but has twin triple 7s, this worries me as the speed isnt that fast. Anyway plenty of time later on to decide.

           

           

          I did a mock up of the wheel house just to see how it looks, the wheelhouse was only taped together and put on temporary supports, the wheelhouse and captains quarters need to be trimmed too, but im very satisfied with the look and realistic form. I may have to look at the bow as it appears a bit sharp, not a lot though.

           

           

           

           

           

           

           

           

           

           

           

           

           

           

           

           

           
           

          Another amateur mistake i made was to buy poundland epoxy, it was terrible stuff, didnt set properly and was very brittle when an area did eventually set. I already did my ribs and deck with the ‘rubbish’ epoxy so redid it with araldite which im sure will be far superior and trustworthy.

            Chris, looks very good so far. nice shape to the hull.
             
            I would use an MFA 800 motor personally, 50mm brass prop… 5A current draw and a slow revving 5000 rpm for that “unhurried” sound. Plus its a heavy motor as you need the weight..
             
            Have you thought what size prop you will likely be using? as this would determine to a degree what motor you need, or if, for instance (as you have bought some motors already) one of the 600`s would be good if geared down for a large prop (say 45mm and above).
             
            Scale speed….make it much too fast and so you will have power for adverse weather and emergency situations. You dont have to use full throttle all the time.
             
            Ashley choosing a motor…stand by for conflicting adcice !!

              Thanks ashley
               
              The prop is 50 or 55mm, yeh the motors ive bought were from 2 different sources the mfa 6:1 was suggested by Dave at action electronics, the 600’s were suggested by a friend in the boat club ive just joined.
              he thought johnsons 600 would be good speedy motor that could be adjusted with the speed controller. The graupner i mistakenly got didnt realise it was 8.4v and im running 12v so it wont do.

                Chris. The 6;1 geared motor would undoubtably drive a prop that size, do not attempt to use either of the 600`s direct though, will burn them or your ESc up.
                 
                I have a 2.5:1 MFA geared unit I tried on an ice breaker and that drove a big prop ok, was a bit noisy though. I think its a suck-it-and-aee situation, get some gear in and test drive first to see what delivers the result you are after, the use of an ammeter to check current draw is very useful here.

                  i did some further snooping and it appears teh johnsson motors i bought from Waddingtons models are 3 pole rated at 20.000 rpm.
                   
                  Ill worry about the motor later as i still have a ton of other work to do.

                    So ive basically spent the last few days cutting and glueing the hull ribs, this isnt a particularly glamerous job however very neccessary.
                    The fibre glass although strong has a certain amount of flex, so the ribs and infills are to act as wall supports to keep a certain amount of rigidity. It is the best that can be done as i need a certain amount of open plan space.

                    The wife has been harping on about putting some paint on ive resisted the temptation making sure i have all the structural work finnished first, id say im nearly there. Only deck supports left to do down below, then ill be ready to commence work on the decks.

                    Ive also been doing some outer hull work only in the form of gentle filling and sanding. the wheel house has also had gentle filling and sanding, so ill maybe prime it tonight, make the wife happy lol.

                      Here is some pictures of the rib and infill work for strength purposes.
                       

                      So i primed and added one top coat of paint, i still have to sand the wheelhouse was primed and one top coat added also. The white visualy makes a difference to the overal look and feel, the wife was maybe right, as i actualy feel as if all my efforts are getting somewhere…hehe

                        So ive spent the last few days, remaking my mould, as i had made good adjustments to the hull and felt it worthwhile to re do for future. At this stage im thinking ahead of maybe making an Early Dawn and North American also. This would involve reducing the length which can be done by adding a temporary stern plate to my mould, as the Early Dawn and North American are the same hull just havent been lengthened.

                        Ive worked out and penciled all the hull markings and openings, ive primed the lower hull ready for first coat of red anti foul.

                        no photos at the moment as interent is at a trickle at the moment

                          Ive been working on the hull details, these are all pencilled on and are ready to be cut/drilled added to etc. Ive added the first coat of red anti foul, lightly sanded. This is all the paint work ill do on the bottom until all the running gear/keel/and bow thrusters etc.

                            Ive been working on running gear, the holes have been drilled. I had to wait and get a longer prop shaft, at the outset i was going for a short as shaft possible, the 90mm was 30mm too short, so i now have a 160mm just to make sure.
                            The reason was to keep all the weight in the middle. Ive drilled through for the bow thrusters and also added the keel to the hull. The hardest part so far has been the bilge keel’s tricky little things, thankfully they are on now and solid.
                            Ive also drilled through all deck openings for water escape, also the under deck tank flows. Ive made my own 7mm rubber strakes just need to prime them and stick them on.
                            Ive got 12 hawsers to drill and anchor area to sort, so not alot left to do asthetically externally.
                            I have stern deck section cut and ready and bow section is also ready. This isnt going to be as straight forward as it appears, im looking to have some fixed sections of deck and moveable areas on moveable areas lol.

                            Coming up to crunch time, ELECTRONICS i have a mixture of excitment and trepidation, as i have very little clue about it

                              The weather here in scotland has been on the cold side, so struggled to get much done with glues and epoxies etc. Ive set up a form of heating in the garage and have managed to do the framework for the deck ive already cut. Much like the hull supports many little pieces to be cut and glued together.
                              I have taken pictures, but there isnt a great deal to see, i have still been plodding away on it most days, just seems im floating about in different sections doing little bits. The hull below water just needs to be finnished with paint, bow thruster grills and to glue on the fake anodes and sonars. Ive done a fair bit on the hull above water, all holes have been drilled and cut including hawsers, the only hole to do is anchor.Much like the bilge keel, ive found the trim that was formerly the deck height a bit more difficult than anticipated, it is so thin in all directions but they are done, just the bow one to do.
                              It would be very easy to just paint the former deck line, also easy to paint the detailing for water escapes and tank in/outflows, but ive done it the hard way, in my mind im hoping it will give greater depth and realism to the model.

                              The deck water escapes and tank flows, i drilled out and cut to there shape, the tank flows are in line with the deck supports i put on earlier and i managed to drill and cut to a decent depth. Because these naturally lie close to the waterline, i prethought about how to tackle this as i dont want water coming in. The holes are sealed from the inside with resin, resin is also applied from the outside. ( havent tested yet)
                              The deck run offs, i will be sealing with clear plastic. Id love to have it all real, just cant afford water in about the electrics i just dont have the space for sealed tanks and water collectors.
                              Ill post pictures again at some point, just not a great deal to show that is different.

                                  More deck work, shame all the individual cuts and work will be hidden from the eye laughing it is strong and light exactly what i want for above waterline. I also placed on about 90 pots just to see what they looked like on.
                                  the look is pretty good, they all fit well per real life, they will sit better once deck finnishing has been completed, the temporary deck had bows in etc, but ill post it up.
                                  So i will be continuing with the bow deck next.

                                      cheers for your feedback, all timber frame is fixed to the sides and the decks are braced off of these, there is a temporary middle support there, that was to hold the moveable deck for the photo. There is plenty of room down below for 2 12v batteries and a motor side by side……unless your worried about vibration? ill be mounting the motor on squishy foam or silicone, obviously not too thick just a few mm
