I don’t now how you scale guys have the patients for such intricate builds. Looks like a lot of hard work to me. :!:

One thing I certainly admire, is a tidy and well kept workshop. “A place for everything, and everything in it’s place.”
Don’t you agree Andrew?

elevator now made i have a bit of sanding to do  rounding the leading edge

before i start the wings i have a good bit of work to do to the fuselage, i'm going to first fix the tail plane on and set the incidence, i've already done a bit of work round where the canopy will go and where the cockpit will start

(http://www.gliderireland.net/forum/images/uploads/andrew%20wallace/IMG_1494.JPG)

i'm always thinking ahead :!:  

i've never built a set of wings with washout before so i'm looking for advice here, you can see from the drawings at the root it's set at 0mm and at rib 14 it's set at 3mm and at rib 27 it's set at 9mm
is there an easy way to build the wing getting the trailing edge straight :?:

hi andrew, k13 looking very good. hope you are enjoying the build. when i built my one, i used lots of diagonal bracing between the formers to help support the sheeting. if you check any full size k13's, (or any schleicher gliders ) you will see these diagonals in place. hope this helps, gb.

hey a big thanks to william and kate for today the day off i got the wing spars made and got the ribs all sorted
(http://www.gliderireland.net/forum/images/uploads/andrew%20wallace/IMG_1596.JPG)
there's 27 ribs and the spar is made out of 1/8 spruce ,there is 3mm of wash out at the start of the aileron and 9mm at the tip

only thing that's bothering me at the moment is the dihedral
(http://www.gliderireland.net/forum/images/uploads/andrew%20wallace/IMG_1597.JPG)
is that 3 degree's or is it 3" at the tip  #-o
Title: ASK-13
Post by: Happy Days on April 29, 2011, 20:00:24 PM
Looking at the plan,….as I read it I’d say it was 3inches of dihedral at a distance of 30 inches presumably from the wing root. Although what significance 30 inches from the root would be I have no idea. :!:

Fred will tell you what it should be…………….FRED, oh FRED!!

Title: ASK-13
Post by: Fred on April 29, 2011, 22:54:54 PM
Hi Andrew / Keith,

I'd say 3.3 degrees /wing (total of 6.6degrees diedhral).
But 3 inches at the tip is also plausible.

That's less than the real one by the way (5 degrees/wing). They have higher diedhral than the "norm" because of the swept wings.

Anyway, the diedhral should be built up on the ribs, where the wing joiner slide on the ribs if you see what I mean.

Hope this helps  :D

ok guys the dihedral is measured in degree's and minutes so the measurement is 3 degree's 30 minutes which works out at 3 1/2 degrees  :lol:  :lol:

Post by: gerryb on May 04, 2011, 00:58:14 AM
hi andrew, you seem to have dih sorted out on k13. have you decided on wing joining system yet? in his 'bible' cliff shows how to build a full length box spar using balsa and ply. i followed this method for my k13 and built a brass box/ steel bar joiner into the box spar. this brass box can be fixed to the spar on its centre line, looking at it from the front.  i also used brass box across the full width of the fuse to carry the steel bar. this means the dih angle is carried right into and across the fuse.  it also means i had to stagger the brass boxes, one in front of the other. because the spar is raked forward and the  brass boxes are at right angles to the fuse centre line, i widened the top and bottom spars to ensure the brass boxes were securely attached to the formers within the spar.
using this method provides you with a very strong wing but you must make sure your measurements are accurate from the start. after almost 20 years and several less than perfect landings, my k13 is still going strong.
 by the way, have you thought of a colour scheme yet? i used the dublin gliding club's ei112 scheme. i think they also had the same scheme with another reg. might be nice to see them both up together, (just a thought).
regards, gb

Title: k 13
Post by: gerryb on September 05, 2011, 01:14:04 AM
hi andrew,
good to see you're back at the building board.

that root rib is a pain in the ass to deal with. the bottom of the rib is not flush with the rest of the ribs. it extends above and below the other ribs, so the height of the rib in your photo is not accurate.

lowering the rib will ease the stress on the spar and allow you to fit it to the root rib easier.

the other thing you can do is cut the spar slot deeper in the rib so it runs straight across all the ribs. you can then add balsa to the top of the spar to fair in the ribs to a streamlined finish.

because the rib extends above & below, i would suggest you leave the root rib off the wing until you have more of the wing constructed. you can then push the root of the wing over the building board for fitting the root rib.

in the previous photo you show the trailing edge fully pinned to the board. i would advise you raise the wing tip about 6mm to allow for a few degrees of washout. this washout starts at the aileron root. in slow flying a/c like the k13, washout is very important, especially when setting up for landing.

hope this helps, keep up the good work, gb
Title: ASK-13
Post by: andrew wallace on September 05, 2011, 16:41:57 PM
ha gerry i knew you would sort it  :clap:
i'm going to take your advice on lowering the main spar think that would be the easier option  :clap:
the trailing edge isn't glued down yet i was thinking about the wash out  :?:  but i have it all sorted in my head now so hopefully things will move along fast now  :D

don't know why but i find it hard to build during the summer months and once it comes to september can't wait to get in the shed  :D
Title: k13
Post by: gerryb on September 05, 2011, 20:39:26 PM
hi andrew,

glad to help but please, please, slow down. the idea is to have the rib fairings on the top of the top spar and on the bottom of the bottom spar. this will give you a much better finish to the wing root. much more scale-like and well worth the effort in the end.

thinking further ahead, if you fit a large curved fairing on top only, it could be difficult to fit the top sheeting because the sheeting goes from a concave shape at the fairing to a convex shape towards the leading edge. in other words, a compound curve. not easy to work with over a fairly small area. just something else to ponder over.

need to kick my arse into gear or the K13 won't be ready this year  :!:
glued the 1/64 ply wood sheet on the top side of the wing hoping to get the bottom done over the weekend  :D
if the models not ready for covering by the end of the month i would say it'll be the end of this year before it's ready or early next year  :(

due to the weather i'm back in the shed working on the model
i've nearly the second wing finished  :clap: i'm gluing the 1/64 ply capping strips on  
once i get the wings sorted on the fuselage that's the model more or less built  :D so fingers crossed

nice going andy, coming together very well.  how did you attatch the wings to the fuse???

he sure did Bill he's still talkin about it today :-)
Owen said that he sang the whole flight  :lol: when he's singing he's happy
they were up for about 30minutes yesterday the wind was from the east which is the worst direction for the gliding club but Owen managed to get a bit of lift off a ploughed field over Limavady direction others were up and down before Stuart :-)

Hi Andrew. I used a 10m roll of white solartex on my K8 and there was plenty left over. Although your K13 is a bit bigger than my K8  :?:  .

after a fortnight of really warm weather i finally can get back into the shed  :lol: temperatures were nearly reaching 40 degree's was worried for a few of my fuselages in case they warped in the heat and a lot of covering has wrinkled biggest fear was the lipo batteries put them in boxes and left them outside.

Well not long back after travelling to the mountain to maiden the K13
Conditions today were maybe a little to blustery 20 + mph  but I went on ahead and gave it a go
Thanks to Richard and Diane who travelled from Craigavon to help with the first flight  :clap:  :clap:  :clap:  :clap:
And what can I say the big model just flew out of Richards hands had a lot of down trim to put in and a few clicks of left aileron and it was sorted  :D
Really pleased with the result

Getting ready now to start building the wing of a 1/4 scale Slingsby Skylark  :D

and excellent stability in a training aircraft.  why aren't all trainers built like this?  i don't know for sure but  maybe it's the construction. to give you an idea of what's involved in building a wing like this, stand with your arms outstretched with your palms turned down, now raise your arms for dihedral, bring them forward for the sweep and now twist your palms so that your little fingers are above your thumbs.  great fun, and the cause of many sleepless nights trying to figure it all out.  well worth it in the end though when you see it flying

I was really worried about hand launching it on my own after a couple of scary moments with the Flair K8 stalling with me my heart was thumping. Once I had it above my head and the wind got under the wings I knew it would go. At one point the wind died away and I took a deep breath thinking I'm going to have to walk but no the 13 was happy floating about 
Gerry believe it or not I was thinking about you when it was flying, seems like a life time ago we were all sitting round the table in the Moss House good times  :)
Keith I haven't a clue about the wings but I love the look of them when it's in the air  :)
I just pray now for more Westerly winds so I can get it back in the air
Now to get the skylark finished  :D
