Devcon1 Posted January 1, 2016 Share Posted January 1, 2016 I'll be doing a smaller version to give a cute little OS10 FSR a home. But I need to finish this first, it's an Airfix 1/48 scale Merlin with a removable side to show the interior. Back on topic. A thoughtful colleague at work gave me a box of balsa that his Dad was throwing out so I won't need to buy any. Powered with this little baby I'm aiming for a span of 36 to 40" I've searched around and a span of 40" seems OK for the OS but any advice on what people think is the optimum span would be appreciated, Regards John Quote Link to comment Share on other sites More sharing options...

Devcon1 Posted January 1, 2016 Author Share Posted January 1, 2016 Thanks PV, I'll aim for 42" then, the model will only ever potter around so as long as it's got sufficient pull to get off the ground I'll be happy. Regards John Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted January 1, 2016 Share Posted January 1, 2016 So we'll have some bigger, and at least one smaller! Sweet! BEB Quote Link to comment Share on other sites More sharing options...

Devcon1 Posted January 19, 2016 Author Share Posted January 19, 2016 Well, I've now cleared the decks ready for having a go at the Ballerina. Although technically off topic here's my excuse for not starting earlier. It's an Airfix 1/48th Merlin with some mods to show the interior with folded rotors and working folding tail.

john stones 1 - Moderator Posted January 19, 2016 Share Posted January 19, 2016 Much too small for my clumsy ability Airfix kits, lump hammer and chainsaw for me. John Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 19, 2016 Share Posted January 19, 2016 That is impressive. This is the sort of thing that takes plasic models into the real realm of modelling Quote Link to comment Share on other sites More sharing options...
Whatgoesup.... Posted January 19, 2016 Share Posted January 19, 2016 That is very nice John, reminiscent of the standard on display at the IPMS Telford last year ! Quote Link to comment Share on other sites More sharing options...
gliggsy Posted January 21, 2016 Share Posted January 21, 2016 Got to admire the dedication and attention to detail of some fellow modellers, stunning work john. Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 25, 2016 Author Share Posted January 25, 2016 Now, temporarily, cured of my plastic addiction I've started. Somewhere down the process I've made an error whilst reducing the plans so I now have a 38" rendition instead of the planned 36" but no worries. I'm also rethinking the power source as I want to add a dummy boxer engine for a bit of extra character so will probably go electric. Here's where I am now.

Peter Miller Posted January 25, 2016 Share Posted January 25, 2016 You should have bought yourself a G-Mark 12 ftat twin. That would have been perfect. I saw one on EBay and I was very tempted at £117 Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 26, 2016 Author Share Posted January 26, 2016 Thanks for your comments on the Airfix project guys Peter, I'd love a working twin but my bank balance tells me otherwise. The dummy engine idea was inspired by your article on the radial one you built so I'll be copying some of your ideas. Regards John Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 26, 2016 Share Posted January 26, 2016 Ah, But only two cylinders! Well, you might preserve your sanity with that. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 26, 2016 Share Posted January 26, 2016 Or perhaps 4 cyinders. I think I would rather buy a G-Mark twin Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 28, 2016 Author Share Posted January 28, 2016 This ones evolving as I go along. I'm trying to use stuff I've got in stock so have decided to make it with a full depth cockpit and two piece wing. Formers all cut and a rough sketch of the fuselage mounted undercarriage. Wing joiners are carbon tubes from an old long since dead shockie. It will also have flaps that continue under the fuselage.

Devcon1 Posted January 30, 2016 Author Share Posted January 30, 2016 Making progress. Trying to keep the structure on the lighter side as I'm conscious Its only got little wings. As I'm building it only with materials in stock I've had to splice the fuselage sides. You can also see the cutout for the flaps that will recess into the fuselage bottom. I think Ive made a mistake with some of the formers by having the grain running verically but I'll leave as is. Method I use for cleaning up the lightning holes, some fairly stiff abrasive paper coiled up and rotated in the hole. I'll leave the wing joiner holes till after fuselage completion in order to get good alignment.

john stones 1 - Moderator Posted January 30, 2016 Share Posted January 30, 2016 Looking like weight will be o.k John, mines not heavy and I'm not a light builder, stick thin vertical strips on the cross grain ones if they concern you maybe ? John Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 30, 2016 Author Share Posted January 30, 2016 Good idea, I'll put some strips on later. I think weight should be OK but I'm trying to keep some in reserve to have a go at a tissue/nylon finish. John Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 30, 2016 Share Posted January 30, 2016 Grain is meant to be vertical on the formers. The draughtsman is obvioulsy not a builder Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 30, 2016 Author Share Posted January 30, 2016 It's funny, every time I tried to decide which was the correct orientation for the former grain I could convince myself both ways were correct. So I've come to the conclusion that next time I'll cut with a 45 degree grain alternating left to right on successive corners, seems logical to me 😁 Fuz taking shape. I left off the fuselage doubler as I've no thin ply in stock so I'll go easy on the lomcevacs !!! John Quote Link to comment Share on other sites More sharing options...

Chris Barlow Posted January 30, 2016 Share Posted January 30, 2016 Do I see a cutter for a square block on there? I too could understand the grain running in both directions and although never done it before decided to try sideways to see if there are any benefits. I may try it again on a slope soarer as the fuselage sometimes gets crushed when gripping it against the wind! Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 30, 2016 Author Share Posted January 30, 2016 Hi Chris. Possibly but I'm not sure what a square block cutter is, could it be a type of spindle moulder tool ? I'll definitely try the alternating 45 degree grain formers next time as it seems logical to me as it introduces the triangle aspect. I'd be curious to see what Peter's thoughts are on this. Hope you don't mind me dragging you into this Peter John Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 31, 2016 Author Share Posted January 31, 2016 I lost my balsa stripping tool so had to resort to this to get the wing spars and strip wood. As mentioned before I was gifted some nice assorted balsa blocks so promising myself only to use materials in stock I used this for my sheeting.
