      hello all for a while i have been looking into all aspects of the modeling world , I am looking for a new hobby to get into . as a nipper used to build models plastic and balsa . Im always the type to be hands on making something as an mechanical engineer by trade .

      Already have a associated 1/10 scale rc car built that in a few days , now waiting for dry weather to use it . After building that i thought i fancy something more of a project to build from scratch where i can adapt to my own specs thought about a RC plane yes i would enjoy that , only 1 thing is that i prefer the building side mainly with alot of time weather dependant with alot of time learning to fly with local clubs or not so local may the case be ….

      this brought me into the thought of boating , seems that its ideal , can build from scratch / plans and adapt as i wish , consuming alot of time to keep myself busy while being at home and can go out now and then in decent weather to sail .

      Im looking into building from plans , bigish compared to the average plastic kit something around 1 meter long . where have people found best place to obtain plans from ?

      looking to build a speed type boat or a cabin cruiser style of boat .

      thanks

          Hi Matt,

          Welcome to the Forum. You should get all the help you need here.

          If you want to ease into the hobby on a scratchbuilding basis then have a look at the plans by Glynn Guest:

          **LINK**

          They are all easy to build and result in good looking model on the pond. For most of them it is possible to get hold of the accompanying build instruction article one way or another.

          If you find you like it then you can tackle something a bit more ambitious, there are hundreds of model boat plans on the MyHobbyStore site.

            thanks colin thats useful to know .

            i do have 1 query …. the sinking feeling with holes in the hull for the prop and the rudder . how do you glue a tube / sleeve into the hull to take a shaft through without gaining water up through the sleeve ?

            Is this done with a type of gland type with packing or a tube with an internal o ring grove machined in for a o ring to fit with the prop shaft or rudder shaft through the o ring ?

            Or is that me over thinking things or there is a simpler way ?

              Most people don't bother making their own and buy a commercial shaft and tube such as these:

              **LINK**

              Basically you have a tube fitted with bearings each end in which a close fitting shaft runs.

              If you place a washer between the tube end and the propeller locknut then when going ahead the washer will pretty much seal the end of the tube and prevent water ingress. You may get a few drops into the boat if the inboard end is below the waterline but this is normal and no cause for concern.

              Rudders are rarely a problem as the top of the tube is usually above the waterline, just use brass tubes and solder the rudder to the inner one or again buy a commercial item:

                ahhh i see now if the waterline is below the top of the tube water should not flow that high , i was just thinking along lines of actual boats but then that would be some fine machinining to make a gland nut on the end of a 5 – 10 mm tube !

                I prefer making my own but for a 1st model i will buy a commercial item . Looking at a few kits what would this be like ?

                  Matt, that is a plan, not a kit. It is a very simple model but also quite small at 18 inches long. It is also quite an old design from 1989, republished in 2012, using polyester resin and ladies tights as a covering for the balsa underneath. These days there are better ways to seal the balsa!

                  If you want a wood kit then look at the Vintage Model Boat Co site.

                  http://www.vintagemodelboats.com/

                  Some of the Glynn Guest designs also have wood packs available with most of the main components laser cut.

                  There are also a lot of conventional kit manufacturers with a wide range of offerings. Most feature readymade moulded hulls.

                    Colin , i thought i said about looking at plans and build from scratch in my 1st post ?

                    Yes i would prefer a wooden kit as i like the idea of building the hull myself . I have spotten some of the woodpacks you can get . In someways i think it takes some of the prep skill from marking and cutting and finishing the wooden sections that make the hull up .

                    Or best even though im quite handly with my carpentry skills to get plans with a wood pack

                      You mentioned a kit in your earlier post! To be clear, scratchbuilding means buying the materials yourself and using the plan to make them into the model. A kit contains prefabricated parts to construct the model. Some kits contain readymade hulls whilst others, such as those from the Vintage Model Boat Co, supply wooden components already cut out for you to assemble and glue together to make the hull.

                      My first reply suggested a Glynn Guest plan because they are straightforward and you make everything yourself from materials (mostly balsa sheet) that you buy yourself. That seems to be what you are looking for.

                      It is best to start with something straightforward as this will give you the techniques needed to tackle something more ambitious in due course. Too many people bite off more than they can chew and become discouraged when things don't turn out the way they had hoped.

                          Matt, the Temerity model is 35 inches long and weighs 5lb. If you buy the magazine as advertised you will get the plan in it which is quite a bargain!

                          I think it would be a good choice for you.

                            Thanks Colin , most helpful.

                            That is a bargain indeed ! Have been looking at some of the kits you listed do like the look of most of the kits on there something like this be nice to build from scratch when more experienced .

                              Hi MattB5m

                              Welcome to the forum.

                              For speed boat a Sea Hornet at 25 inches.

                              Cabin cruiser 29 inches a Sea Rover.

                              For cabin cruiser around 36 inches a Sea Commander, Swordsman.

                              Some of these are available in kit form.

                              The large models are easy to work on I have found after building the Sea Hornet 2015(check out my build on this forum).

                              I have the Sea Rover plans which I rescanned and resized from 29 to 35 inches.

                              Mainly because we run in a salt water canal or I run in open water.

                                Hello Harry and thank you for the welcome , I have quite a few possible sailing locations a big open lake and lots of smaller ones around Swindon where I'm from . There is also the river Thames within 20 minute drive from me . So quite lucky .

                                  re; propshafts ,

                                  Check out Raboesch propshafts, available in the UK. Well engineered, with a seal and bronze bearing at the inboard end.

                                    We made our own with brass tube(hobby shop) custom Teflon bearing and Teflon thrust washer for the water end.

                                    An end roller bearing for the motor end with a oil tube capped with 4mm IC fuel tube and end stop.

                                    Motor revs up to about 2900rpm and 1600watt brushless motors.

                                            Terry would you have any pictures of the propshaft you made ?

                                            Easiest way to make a propshaft:

                                            1 – Buy a brass tube – say 6-8mm. Cut to length.

                                            2 – Buy a length of nylon rod the same width. Cut off 2 8mm lengths.

                                            3 – Drill a 4mm hole in the centre of each of these lengths.

                                            4 – Put a 4mm bolt through the hole. Put the bolt end in a drill. Use a file to cut a rebate in the disk so that it fits snugly into the prop-tube

                                            5 – Cut a slightly longer length of 4mm piano wire, and tap one end 4M

                                            That will be fine for most sports boats. If you want a smaller, simpler prop fitting, see – **LINK**
