john stones 1 - Moderator Posted October 27, 2014 Author Share Posted October 27, 2014 Full of cold again and a splitting headache, so no work n i'm bored hung about long enough ...so build a wing. Apologies for off plan but it's dimensions and outline I want, how I get there is not important. R1 will be 1/8 with a doubler and centre section will be 1/8 ribs. Bit of re-cutting to do so started wing so it's drying. Spruce mainspars and balsa rear ones. Yes it will be a little heavier, but it will still be a light wing. John p.s feel free to disagree or comment Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 27, 2014 Share Posted October 27, 2014 Great John good to see you make a start on the wing, sorry you aren't feeling too bright As I typed the explanantion to Nigel last night I thought you could make a couple of R1 copies to build the centre section So either great minds think alike, or is it fools never differ? Anyway it will be interesting to see how you get on. Seeing as you have fitted leading edges are you going to sheet perpendicular to it?

john stones 1 - Moderator Posted October 27, 2014 Author Share Posted October 27, 2014 I fitted leading edge to stiffen it Danny, I made a good job of cutting my ribs (for me) but may have to tickle the upper spar slots, so thought it best to add it. Yes I normally butt sheeting up to it. Time I bought myself a long Permagrit My wings glued up, new R1's made and doublers drying, so I now need to make a dihedral template up. I am beginning to wonder if my 52 FS might be better in this...very light A few minor issues aside I reckon the plan was a good choice John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 27, 2014 Author Share Posted October 27, 2014 Well that never took long, will be dry enough to add t/edge spars before bedtime, best get them cut out. David put some great photos on and now i'm a bit worried about going over 7kg when I add the rivets The fairings around wing and fin are the sort of stuff i'm looking forward to + access/ inspection panels. Sliding canopy/ cockpit detail, would be nice but looks beyond me John Quote Link to comment Share on other sites More sharing options...
Nev Posted October 27, 2014 Share Posted October 27, 2014 Good wing so far John. This looks like the kind of wing building I can recognise / cope with, especially if it can be done in 2 halves and joined later. Watching closely, hope the 2 halves go together without any problem.

john stones 1 - Moderator Posted October 27, 2014 Author Share Posted October 27, 2014 That's my thinking Nev I think we all are used to this method, if we build 3 straight bits what can go wrong John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 27, 2014 Author Share Posted October 27, 2014 Wings dry so I looked at top spar, not too bad a bit of tickling with these tools n jobs a good un. Manicure file is a tip I picked up on here great for delicate work rear spar is a good fit but I don't fancy pinning it, so will cyano tomorrow. If you cut your own ribs don't forget to add the tabs makes it much easier. John Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted October 28, 2014 Author Share Posted October 28, 2014 Not be a lot done tonight bought some cyano from screwfix £3...bargain However...if saving weight means breathing this stuff in, i'll stick with pva Gonna have one of these whilst glue dries John Quote Link to comment Share on other sites More sharing options...
Terry Walters Posted October 28, 2014 Share Posted October 28, 2014 I agree with you John about CA - I do use it now and again but do not like it and it doesn't much like me. Aliphatic for me. I also listen to Elton John sometimes - I take it that is a CD case for The Lion King? Terry Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted October 29, 2014 Author Share Posted October 29, 2014 Something like this is how I will do mine...drawing is not correct shape U/c I will do this way, just another quirk of mine. John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 29, 2014 Author Share Posted October 29, 2014 On the leading and trailing edge we have angles, I am getting rid of these with wedges...then my brace will be straight ( not much different to the plan really ) I will slot the section ribs to join with braces, again not much different to the plan, but in a different order. Any snags i'll deal with as I come to them What's my advice to others ? well if you have accurate cut parts once you've joined the spar to B2, build as Danny/Martin John Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 29, 2014 Share Posted October 29, 2014 Hi John good to see you are grasping the Bull by the horns So you have cut the leading edge and the wedge B1 short of the centreline? how are you going to put the strength back? That line in front of R1 on B1 is not a cut, its a change in surface angle. B1 is supposed to be contigous as is the trailing edge joiner B3 Cheers Danny Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 29, 2014 Author Share Posted October 29, 2014 Yes Danny I know it's a change in angle, There will be a ply brace there similar to B3. Both my new R1's are 1/8 now. I reckon B2's provide most of the strength anyway. Still got some thinking to do on centre bit, so will build my 2 panels for now. Bull by the horns ? here's hoping I don't get gored. John Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted October 29, 2014 Share Posted October 29, 2014 I'm increasingly thinking I will do the fuselage before the wing. I always used to anyway. Quote Link to comment Share on other sites More sharing options...

Colin Leighfield Posted October 29, 2014 Share Posted October 29, 2014 Probably John! I want to make sure that there are no issues in ensuring that the wing fits properly, also I might make a couple of changes which I'm still thinking about. we'll see.

Danny Fenton Posted October 29, 2014 Share Posted October 29, 2014 You think it matters which bit you have first to ensure the other fits, too many sangrias You can't do the fairing without the wing Colin, so may as well get it out of the way Cheers Danny Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted October 29, 2014 Share Posted October 29, 2014 Probably so Danny, reality will hit me on November 06! Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 29, 2014 Author Share Posted October 29, 2014 Made a dihedral template and stuck my rib in, next is a few shear webs to hold it true, when dry I can lift it and get moving again I've had the long rule on it and all seems straight, it all looks strong enough to me Washout ? at the weight this will be i'm not worried about it John Edited By john stones 1 on 29/10/2014 20:37:14 Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted October 30, 2014 Share Posted October 30, 2014 You're probably right John and it perhaps won't be a big issue. Can't see what difference the weight makes though, except the difference in the speed at which the wing-tip drops if it is going to do that?

john stones 1 - Moderator Posted October 30, 2014 Author Share Posted October 30, 2014 You know far more about aircraft than me Colin, I've always thought the heavier the wing loading, the more speed needed on landing to avoid a tip stall, or is the speed the same but more violent when it happens ? John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 30, 2014 Author Share Posted October 30, 2014 Fitted shear webs in alternate bays 1/16 balsa...bit more weight added the wing is lifted from my board now, feels nice and solid. Like Danny I can't see nothing built in, looks perfectly true to me. Waiting in for a delivery today...so shall tape the plan to a window and trace left panel...how daft is that ?
