      Good luck, I've done a bit of fibreglassing in the past but not on this scale, I found it quite daunting.

      Thanks Trevor,

      even with the trials and tribulations i still enjoy it more than some processes of hull building.

        SO!!, WHAT COMES NEXT?

        The moulds have been readied for taking mouldings by smoothing and getting ready for the job, lumps and bumps taken out, hollow spots filled and sanded all over.

        Given 5 layers of wax pollish, and now had the final PVA release agent painted on.

        Next tonight will be the gelcoat, and unlike the cabin mould which was bolted together, the two halves will be left detatched for the painting of the gelcoat

        AND the first layers in a certain fashion of the grp matting, and this part will be explained later and for good reason why.

          Everything going to plan!

          And I love it when a plan comes together.

          the hull is covered in white gelcoat now, except for the keel, but this will be done once the two halves are eventually bolted together.

            I`ve just spent the afternoon reading your posting on the latest lifeboat build.

            That is some effort you`ve put in there and the end result will look very satisfying I`m sure. I liked the idea of making the rivet heads, very useful.

            Best of luck with the onward progress.

            Jim.

              Thanks Jim…….the end is near, within 24 hours for the mouldings to pop out, i hope.

                Hopefully, SUCCESS!!!.

                I have laid up the two halves of the hull seperately. leaving the stem, stern and keel still without matting on them.

                Why???, you ask.

                Well, the hull is so deep with vertical sides for most of the length that had I sat the hull mould on its keel bolted together and then laid the matting and resin in, it would have peeled away from the mould at the bulwarks level, as it did when I first started moulding the Clyde lifeboat hulls 12 years ago.

                This was because of the weight of the sodden resin filled matting not being able to hang on to the gelcoat at the bulwarks.

                However, the Clyde didn't have belting around the sheer line as this one does, and thus adding extra weight to the lay up, which would definately come away at the sheer line, taking the belting with it.

                Laying the mould flat on its side, as two parts has elleviated this problem, and although it adds a little more time to the lay up process…….rather this, than a knackered moulding.

                Hopefully with a bit of a clean up of the jointing flange, I should be able to bolt both sides together this afternoon, and join both halves of the moulding together with strips of mattimg and resin.

                  White gelcoat was painted into the keel of the boat once the two halves had been bolted tightly together and the final process had begun.

                  However before cutting and stripping ready sized strips of grp matting I realised I was running short on disposable paint brushes, and so went out to Home Bargains and bought 4 packs of 5 assorted sized in a pack for £1.29 a pack…………a bargain.

                  Back home I started laying the strips into the trough forming the keel, and within 40 minutes….EUREKA!!!!!

                  The two part moulding is now ONE hull.

                  In all with cabin, the process has taken 5 days I think…….hope to cut this time with better organisation of time and motion……but on my side…….it's a big boat, a first time taking all precautions to make it a sturdy and useable set of moulds, which I think I have achieved………..AND it's 8 years since I made my last set of moulds.

                      Thanks Richard……I've enjoyed the task and challenge of bringing to life, a model of a lifeboat i have never seen anyone build before.

                      I like building the obscure craft.

                        Are you all ready for this, boys and girls, coz I am buzzing, myself.

                        Needed sometime alone this afternoon without any interuptions, and so after I had taken my daughter to work, I came back to split the moulds.

                        But before lunch I laid up the matting for the second of 3 cabins I need to proceed and to be able then to put moulds and plugs away for the time being, until I decide what to do…….bearing it takes almost five days of on and off work to get a set out, and in those 5 days I can do sod all else in my workshop as all the equipment and useables take up the whole workshop.

                        And this afternoon and evening, I'll wax and paint the PVA release on to the moulds before painting on the gelcoat before I go to bed tonight………will sleep well tonight.

                        ANYWAY!…….For you all a short video and some photos of the first moulding out of a new set of moulds.

                        Hope you like them, I give you the RNLB Princess Mary of Padstow !!!

                          Just thought I would unite cabin and hull……….

                          Enough to get the juices going lol.

                            You'll be able to sit in that and paddle it!

                            Lovely looking job. When you compare that hull to available manufactured items on the market you could sell that for a substantial amount.

                              I would need a new extension to my workshop, as at the mo, all surfaces are taken up with equipment and consumables, with no place too work………….plus, it take 2/3 days hard work just to produce one set of mouldings Richard….I'll sell it all and let someone else produce it, easier. 

                              there has been a Coracle for sale on ebay for a few weeks and not a single bid, he keeps relisting…………

                              I have been thinking and toying with the idea of buying it and using the model to tow me down Windermere in it but the guy just won't entertain me organising a courier to pick it up……..am I mad or what, lol.

                                  On the basis your thinking of buying a Coracle ! yes your completely bonkers

                                  Super job, just have to finish the top half now !!

                                  Regards Ray

                                    When you`ve gone to the lengths you have to produce that that hull, that`s true model making.

                                    Looking at the last side view picture and imagining it finished and painted, what a site that will be.

                                    Terrific work,

                                    Jim.

                                      I have 3 sets to pull out Richard, and then I can clear the decks of all the grp gear, and start building, and am on the 3rd set which I'll have finished by wednesday lunch time……………………….looking forward to that moment.

                                      It'll be nice just to be able to get to my lathe to turn the bearings for my prop tubes…..havent seen it for weeks, lol……and its big enough.

                                        must admit, think i'm going round in circles thinking of a coracle, lol.

                                          Taking it to blackpool at the weekend for the model show, and putting it on the Lifeboat Enthusiast stand…..

                                            My workshop is begining to look more like S.E.Saunders by the day!

                                            One hull out of the moulds, the 2nd of 3 hulls ready and splitting the moulds ready to emerge as soon as I can get it on the workmate, and the 3rd of 3 cabins in the mould and going off as I speal on, lol.

                                            The 3rd hull will go in the mould tonight when I gelcoat it, and do the moulding tomorrow.

                                            Well well, I split the mould this morning, and trimmed all the wast off the new hull.

                                            They are now becoming easier to split and remove, the more they are waxed….
                                            3rd and final hull going through the process of being readied for the gelcote tonight, if not before.

                                              And the cupboard, or at least flat space is now bare!!

                                              No chopped strand mattimg left and very little resin to complete the other side of the final hull for this session of moulding.

                                              Hopefully more supplies will arrive today so that I can complete the moulding within the optimum 24 hour period of bonding gelcoat to resin and matting.

                                              Whilst waiting for these supplies to arive, I have started on laying up a big rubber mould in a Lego box of an important part of the boat.

                                              Can anyone guess what it might be…….it took a ton of rubber I might say too. So that will be next on the list for replenishing……….model boat building……..the expense of it never ends!

                                                Made a mould today to replicate the rudder that I had made for the boat in wood, and it cast well in polyurethane resin.

                                                  i'm having a few days off before i clean up the two sets of mouldings that i am going to work on……….one set still in the moulds.

                                                  Have had 3 says helping Dave Stavros Jones, and others set up the tables, then the LBES Stand and today…buying materials and chatting with old and new friends at the first day of the show, plus other dramas that i can't be bothered talking about although very stressfull

                                                  So tomorrow, going to have a relaxing day at the show, and then start again on monday or tursday on the tidying of the workshop from the rigours of grp moulding and the mess it leaves, before getting on thith the build of my two model lifeboats.

                                                  but the show is a good one and going from strength to strength with new attractions every year.

                                                  i'll take some photos tomorrow.

                                                    Blackpool Show was a great weekend, due much to the organisation on the thursday and friday of Dave Stav|ros Jones who managed to get all the table possitions for traders and clubs to set out their stalls, and make the setting up on the friday easier for those coming in and out.

                                                    Sadly Dave officially retired after the prize giving on Sunday, due to his health and well being, so one hopes that other persons will come forward next year to hopefully do what dave has done for a good number of years to make sure everything runs smoothly over the weekend.

                                                    However the show went well and many great models of all kinds, [not just ships] for everyone to feast their eyes on, and some good traders offering show prices.

                                                    I myself showed the hull and cabin for the RNLB Princess Mary which gained some interest and encouraging comments.

                                                    And then i set off to by some supplies to bui;ld mine and one for a friend. SLEC for ply wood and epoxy, Tony Green Steam for supplies of plasticsard. Mike McGough for a box of EMA Plastiweld, Mike Alsop to order a George reign RNLI Flag for the lifeboat, and lastly to Propshop to buy shafts'tubes and 55mm bronze propellers…the only company that i will entertain for my boats props……..they are just beautiful works of art.

                                                    And today i started using my plasicard and glue for making some benches and graitings plus companionway covers for the two boats…building has begun again after a weekend of meeting old, new and good friends, models of all kinds mixed with great cake supplied by Martin Kinghoward, all mixed with a great deal of merryment merth and happiness, but also tinged with some amount of personal sadness.

                                                      On saturday at Blackpool show I bought my 55mm props for the Barnett and proptubes/shafts for the boat.

                                                      However I bought just two 12" tubes, as the proprietor didn't have any 6" or 7" tubes. The shafts, he had 3 of the longest, and I had one at home.

                                                      So this afternoon, I cut both 12" tubes in two making 4 x 6" tubes for the four shafts needed.

                                                      However, this left me 4 barings missing for the cut ends, and so found a length of brass rod to the same diameter as the tubes, and using a centre point used the laithe to drill a starter for the drill bit.

                                                      Set the drill bit into the chuck and reamed out the hole to take the prop shaft.

                                                      It was then just a matter of cutting the shaft on the marked brass rod to form the smaller diameter shaft to be placed into the tube at the bare end.

                                                      Having made all four bearings it was just a matter of using a wooden mallet to drive home the new bearings.

                                                      Job's a guddun!
