I tried a lump of blutac on 0.5mm wire and it didn’t bend too much. It might be further support by the other wires, all depends how high the balloon will be flying.

Knowing your previous assembly, it should be a nice model.👍 Rob, you should have asked me about the balloon, it is very quick to draw and print. It would have been much finer than Shapeways. All it had to do was cross the Channel to get to you in a letter Pacal - That was very kind and generous. You'll have to be careful or you'll have a stream of begging letters. I would have asumed it would be difficult to 3D model. The sculp is very good - the printing not so much. On 2/2/2022 at 11:25 PM, Courageous said: ...a raft!

HTH. Thanks Rob - That was one of my research references and very inspiring On 2/3/2022 at 6:17 AM, beefy66 said: Rob have you considered a back drop so you could attach the balloon from the rear you could make it ala Longshanks method of display as a picture frame and still have the thin wire as support from below just my thoughts Stay Safe beefy I have Beefy and it remains an option though not a preferred one.

Bobs_Buckles Posted February 6, 2022 Share Posted February 6, 2022 Ernie Ball 14 gauge steel guitar string may do the trick. Depends (obviously) on the weight of the gasbag. Whatever way you go, GOOD LUCK! Cheers, Bob 😀 1 Link to comment Share on other sites More sharing options...

Depends (obviously) on the weight of the gasbag. Whatever way you go, GOOD LUCK! Cheers, Bob 😀 Thanks Bob Following the instructions of my Zen Master ( @longshanks) I penned the ribs for them to show through at the sanding stage and then opened th car filler ...... The first time I've ever used - smells great but not so easy to apply though I agree about it drying fast I thought I'd work little by little And then ignoring the advice of you all and my Zen master I couldn't resist uasing Sylmasta "A&B" modelling putty to fill the stern. Possibly harder to sand BUT you are able to smooth it and contour it unlike the S-38 car filler The A&B putty was old so I'm waiting for some replacement "Magic Sculp" to arrive. The next stage I feel is the hardest and that's to model the Bulwarks, particularly the transom and bow. The plan is to stick som 0.16mm plastic sheet into a groove at the level of the deck and once it's fixed, fill and sand to get a flush join - that at least is the plan. I'm aiming to do one side at a time. Fillets were added, the lower Bulwark contour cut and the process of "welding" it with Tamiya Extra Thin styrene cement, bit by bit Looks a flippin mess at the moment We'll see Thanks for looking Rob 18 Link to comment Share on other sites More sharing options...
ArnoldAmbrose Posted February 7, 2022 Share Posted February 7, 2022 Gidday Rob, yeah it looks a mess at the moment but it's the final photo in the WIP thread, and those in the RFI section that matter. 🙂 Actually, so do all the other photos, including these ones, that matter. In a sort of "how to" or "how not to" sort of way. I'm still following your method with keen interest. Regards, Jeff. 1 1 Link to comment Share on other sites More sharing options...
Steve D Posted February 7, 2022 Share Posted February 7, 2022 Rob, It's a bit late for this build, but what I do in these circumstances is infill the frames with balsa wood (marked to the largest frame each time) and then sand that back to the frames. This is quick and easy, the filler can then be added as a thin layer to finish the job. May be a little easier for next time Cheers Steve 5 1 Link to comment Share on other sites More sharing options...

foeth Posted February 8, 2022 Share Posted February 8, 2022 For both the balloon and the hull: did you consider vacuum forming? Really easy to do and you get a very light balloon and a nice hollow hull? 1 Link to comment Share on other sites More sharing options...

Really easy to do and you get a very light balloon and a nice hollow hull? Thanks EJ - No - well outside of my comfort zone and despite the print/surface qaulity the ballon is really very detailed. I'm still absorbing basic hull building steps So once again with Thanks to my Zen Master - Obi Wan Longshanks and acknowledging his patience taking me through steps that a Drunken Donkey would have picked up 5 x faster, it's on with the show...... the Bulwark topping is 0.3 x0.5mm strip I elected to sand and fill the port side completely before progressing to the starboard bulwark Getting the transom rail to "curve" with a single sheet of plastic was a trial It was neater () than I anticipated but the overhanging upward angle was not present I was really happy for a couple of hours until the demons came. So I cut the rear bulwark away and attempted to "salvage" the build and try to get that overhang more realistic which in many respects is the visual signature for these vessels The problem really arose by trying to use just one piece of palstic each side - even the thin stuff just isn't pliable enough I cut pieces of plastic by trial and error to get the right angle - it took 6 You can see the sort of thing in the next pic at the top Hugely more realistic stern, which still needs sanding down Hull and Deck now complete to my satisfaction ......unless the demons come again Zen Master is happy and has welcomed me to his world - jes suis arriviste!

If I may correct your point, the ships boats hulls which I produce in tissue paper on a mould go down to 5 cm (and could be smaller) using balsa between frames quite successfully. The other point on taking a tissue shell off a mould is that you can produce many very quickly once you have the mould so a fleet of trawlers is within reach. 6-8 layers of tissue soaked in weak pva make a very strong shell that can include the bulwarks and is easy to sand. As ever I unapologetically lead the charge re using more traditional materials Cheers Steve 2 1 Link to comment Share on other sites More sharing options...

Regards, Jeff. Hi Jeff - it's a resin dinghy from a Black Cat models LCI. I was just test fitting it to the stern to check on clearance. With hull nearly cleanly sanded, it's superstucture and fittings next. Rob 3 1 Link to comment Share on other sites More sharing options...
robgizlu Posted February 15, 2022 Author Share Posted February 15, 2022 Well - a couple fo sanding sticks later tkes to this... I ran a light spray of Alclad primer over just to check for "dings" - it was remarkably clear And then sanded it off to get to thepastic surface as it 's easier to weld thin strips of gunwhale rail and rubbing strips The rubbing strips themeslves are sanded back to reduce their height resulting in several "fractures" - especially where I used CA glue over the resin Scupper holes were also drilled and carefully filed And while all this has been going on I've given 2 separate coats of Mig Ammo One Shot to the ballon and sanded it back The surface is just Horrible! The plan is another coat of acrylic primer then some Alcald primer. More soon I'm enjoying this Rob 20 Link to comment Share on other sites More sharing options...
