      Please be gentle with me, this is my first boat build other than a Zwarte Zee which I'm looking for the accessory pack for and a continuation build of the Löschkreuzer Weser.

      Laid the 2? keels today

      img_20190322_200358.jpg

      And cut the pairs of frames etc, they just need sanding to size. I used double sided tape to hold the pairs together, worked well. smiley

      What didn't work quite so well was the use of spray mount, went a bit too heavy on the keel and was a sod to get the paper off. sad

      I plan to dry build the frames first and check all is ok before gluing and also to see if there is enough room for a steam plant, if not, sparks it is then.

          Hi Roger

          Great to see some more building going on. I use spray mount from time to time but the pukka 3M stuff is quite expensive. I have gone over to Pritt Stick or cheap equivalent which comes off quite easily especially if lightly dampened.

          It is always good to plan your motor installation at the earliest possible stage so a good plan to see how it all fits before gluing. I can see this is more important with a steam installation as it will be space hungry.

          If find that most framing could be slimmed down to a great extent to allow more room for machinery. It can be useful to have the strength and stiffness while the build is going on but when all planked up and the deck on, the hull will be very strong with minimal framing.

          Following with interest and I like the subject.

            I have found an issues with frame 7, it is too low on the deck line (sheerline?), by 5 or 6 mm.

            How do these issues get highlighted?

            Anyway, time for sticky bits frown

              Hi Roger,

              As the plan is produced on auto cad or similar, the drawings usually a scan of the builders draft plans so will not be very exact in some respects, you just need to ad-lib and add some extra material so it fits

              Regards Ray

                Hi. Ray and Roger, I am also building the James P. Woods, and as Ray says there are some discrepancies in the drawings, there is also a lot of differences between the drawings and the photo,s of the build, so I think we use the drawings as a guide and then just check and recheck that everything is fair before adding the deck and planking.

                Regards.

                Eddie.

                  Hi both, I realize that now, guess I'm too used to engineers drawings where errors are a normally a lot smaller.

                  Eddie, Are you going to do a build log of yours? Only so that I can pick your brains. laugh

                    Hi Roger,

                    As you will know LBSC & Martin Evans didn't always get the dims right every time 😀 just enjoy the process , keep us posted .Regards

                    Eddie,

                    Had a great morning boating with my 2 grandsons at Bluewater, makes it all worth while 😁 and they enjoyed it.

                    Regards Ray

                      Yes Ray, one of my locos is a LBSC Speedy, the other a Simplex.

                      Whereabouts is Bluewater? It sounds familiar!

                        Hi. Roger, I wasn't planning and doing a build log, I didn't want to steal your thunder.

                        I seem to be a bit ahead of you as I have started on the topworks I am quite happy to pass on any thing that I think may help,For instance start to varnish the inside of the hull as you put the planks on, it will be impossible to get a brush down to the keel with all the planks on in some places, I am fitting an MFA 800 motor with belt drive reduction.

                        I have also increased the the length of the deck opening from frame 7 to frame 6, a 9 cell NiMH battery just fits into this extra space, giving more room for everything else.

                        All the inside of the hull that will be accessible for ballast has been treated to a dose of resin and glass fibre, I reckon that at least 20lbs. will be needed to get it down to its water line. The motor mount is not going to be fixed in place until the ballast is in place, the electronics board will be fixed with screws onto cross bearers so that it can be removed if the need arises.

                        I hope some of the above may be of help.

                        Ray, I haven't been able to go sailing for a couple of weeks now due to other commitments, and before that the only sailing we did was in the coffee shop on site at Wicksteed Park,so I am looking forward  to getting Susie May on the water again.

                        Regards.

                        Eddie.

                          Hi Eddie,

                          You wouldn't be stealing my thunder, rather stopping me disappearing into a whirlpool never to be seen again. 😁

                          Thanks for the advice, it will be taken up but I would love to see pics of your build as they say they're worth a 1000 words. Where do I find the belt reduction gearbox please?

                          Also what size and type of propshaft are you using?

                          I think my idea of using a steam plant will have to wait until I get this build safely afloat so I will concentrate on expanding the electronics side for a bit of realism.

                          Regards

                          Roger

                            Bluewater shopping centre is the home of the Chantry model boat club in Kent, good weather yesterday a good turn out of members & boats. 9,000 spaces in the car park 😀

                            Regards Ray

                              Hi. Roger, some photos of my build.dscf3427.jpg

                              The hull so far.

                              dscf3424.jpg

                              looking into the engine and electronics bay. The extension to the bay is on the left, from frame 7 forward to frame 6.

                              The prop shaft is a Raboesch waterproof 290mm M4 thread, it could be shorter. Cornwall model boats sell it.

                              dscf3422.jpg

                              The MFA torpedo 800 in place, the mount for the motor is in two halves as the output shaft is below the motor.

                              Cornwall model boats sell it but are out of stock at the moment, but Component Shop have it in stock.

                              dscf3421.jpg

                              Everything roughly in place, the battery sits in the extra space made by extending the hatch area, the blue box at the lower right is a motor sound generator, set up for a single cylinder steam engine.

                              I have also added a second cable for the rudder just in case a single one cannot push the rudder against the prop wash.

                              Regards.

                              Eddie

                                Wow Eddie, do they call you Rocketman?wink I'm still getting my head round the best way to plank at the moment.

                                I have some lipo battery packs, any reason not to use them?

                                What size propeller would be suitable?

                                Regards

                                  Hi. Roger, perhaps I have too much time on my hands, I'm fairly sure you can use a lipo but you will need a lipo safe ESC, perhaps someone more knowledgeable than me will comment?

                                  As the RPM at the output shaft at 12 volts is around 2500rpm I will be going for a 4 bladed prop of 55-60mm. diameter, again anyone with experience of this type of setup please feel free to let us know.

                                  Regards.

                                    I would plank from the deck down to give you fair top sides, have a look at my builds in my album Cullamix and Spanish fishing boat, there are build threads for both but that are a while ago.

                                    Regards Ray

                                      Eddie, now I'm retired I thought yippee now I can spend my time in the workshop, then reality kicked in, rather the missus did, so now I'm working on the 10 year plan I started 30 years ago. crying Oh how I hate decorating!!!

                                      I will get more info before I make any decisions re lipo batteries.

                                      Ray, I had a look in your album but went boat blind laugh It is the way I'm working it's just me being a bit nervous about messing up, it's a whole new world to me.

                                      Cheers

                                        Yes I'm rather manic building most things but as I play/work on a computer all day, so like to get building in the evening it's a tangible end product, you can't hit the delete key my mistake 😊 I will get back to the engineering some day and finish my Boxhill.

                                          Is that the 0-6-0 T?

                                          My last 15 years of work was data preparation for various companies and meant I was working away from home for 5-6 days a week, didn't do a lot for recreation or for home life, if I had my time again would never do it whatever the salary was. for what I earned my pensions got stuffed up anyway so I make ends meet and have enough left to dabble in my hobbies.

                                          I built my workshop up by buying tatty machines and restoring them, my last was a 1938 Denham Junior MkII lathe with little wear but looked like it had been repainted by a colour blind person with a whitewash brush. Just picked up a sensitive drill press at a local auction tonight for £28. It comes to those who wait. smiley

                                                Hi. Roger, just had a thought, are we talking about the same scale of tug? I am building the larger version, so all my comments refer to that larger one and the sizes I gave on the other thread are for the bigger boat.

                                                The reduced size in the mag. is about 1/3 smaller.

                                                  I am have nervous thought about upscaling a second version big enough for steam.

                                                  I will post some pprogress soon, been busy outside with this summer we're having. Trouble is my hands and knees are knackered after so can't get into the dockyard but do intend to be complete and sailing by July.

                                                  Also have a 'BEE' to complete, it's a close to half scale hot air engine from the early 1900's

                                                    Hi. Roger, good to know we are on the same pagesmiley. Yes I am working on the first level of the superstructure, still have 50 of the 200 vertical strips to fit.

                                                    My next main job is covering the hull with glass fibre and epoxy resin, am also waiting for the next issue of MB to find out what the designer has done, paint, or stain and varnish.

                                                    Like you I am used to engineering drawings that give you all the information and dimensions to make a part or machine a casting, boat drawings leave a lot for you to fill in, one set of drawings that I am building a Thames barge from are to scale but with the full size dimensions! but its all good fun.

                                                    Regards.

                                                    Eddie.

                                                      Hi Eddie, Are you following the designers method for building the superstructure? I'm thinking of using ply with planking on top but with a more hollow inside but I'm open to advice.

                                                      Like you I plan to cover the hull the same as you but will need to order the glass and epoxy, I'm thinking on 24gsm cloth and Zap Z-Poxy 12oz Epoxy Finishing Resin PT40, again open to advice from anyone smiley

                                                      I assume the Thames barge will be to the same scale as the tug?

                                                      I notice you said that the propshaft could have been shorter, would you have gone for the 261mm then?

                                                      Regards

                                                      Roger
