Gliders > Slope Soaring
I'm drowning, in bits of an Mu28

Ar-ha!…..........after a meeting with a fiend, and an email from another friend. :D (Actually I shouldn’t call them ‘friends’, but clients. You see, clients are tax deductible, friends aren’t! :wink: ) The Keithy has found the answer. :P
Actually it’s so obvious I don’t know why I didn’t think of it myself. :roll:
Shall I tell you what the answer is? Do you really want to know?? 8)
Oh, all right then. The answer is “Shims” :shock:
To explain:-
When I place the bottom parts of each section onto the bench, the sections that are lower, than the adjacent section, simply have some pieces of thin ply, or similar material placed underneath them to bring them up to the same height. If one side of a section is lower than the other, the same solution applies.
THERE,…..pure & simple. (Just like me! :lol: )

Ok, was minding my own business on the Interweb, when I found this! :
Though of you. Look how this glider looks cool! :mrgreen:
Nice change from the Fox, Swift etc etc !
Need more motivation? \:D/
Happy Days:
Hey, I’ve only just come across this picture Fred. :D
Hhhhmmmmm, does look kinda neat, 8) ….but what does it fly like??? :!:
Guess there’s only one way to find out. Get someone to build my kit for me and then go fly it! 8) 8)
Offers anyone? :wink:

Happy Days:
So the build begins. After much deliberating and procrastinating I’ve started assembling the wings.(Please don’t all faint, or worse, start laughing!)
But! I’ve hit a problem…………. :?:
Looking at Fred’s structure for a composite spar, http://www.gliderireland.net/index.php/techniques/composite-spars my thought is this:
It’s a little difficult to explain so, dear readers, imagine the wing profile. Thinking about the top of the thickest part of the profile.
Fred suggests sanding a ’groove’ equal to the thickness of the carbon tape that is to be laid into it. All good so far. :)
The problem comes in that the bottom of the groove will be ‘flat.’ Therefore after the tape has been epoxyed into place the top of the tape will also be flat. This will make the top of the thickest section of the profile flat and not ‘rounded’ as it would be if I hadn’t sanded a groove and fitted the tape into the top of the wing. :!:
The tape is 37mm wide, and the wing tip chord is 180mm,….that means 20% of the top of the profile at the tip will be flat instead of the correct profile. (Basically a convex arc)
Of course my big question is,….Will it adversely effect the flying capability???
What do you think gentlemen?

billscottni:
37mm seems very wide for a spar Keith. Half of that would be plenty and double the thickness if you're concerned. Instead of sanding of out, you could cut your groove with a hot wire and then trim it to fit back once the spar is in?
Fred may have a better suggestion
