bexrbetter Posted January 10, 2017 Author Share Posted January 10, 2017 Nothing overly special today, just fitting up the turtle deck and tail to the new sides and some internal bracing in the tail ... 8 Link to comment Share on other sites More sharing options...
bexrbetter Posted January 17, 2017 Author Share Posted January 17, 2017 Soooo.... Over the weekend I redesigned the wing box for some good reasons, as well as ever, simplicity, speed and cost. Yesterday and today busy building it. The theory is simple, tapered wing ends into a tapered, self locating and aligning. I just got enough of one partial wing finished tonight and it works a treat, fits so damn good that I actually am concerned about taper stiction, I had to wiggle it quite a bit to get it back out! 3 Link to comment Share on other sites More sharing options...
bexrbetter Posted January 17, 2017 Author Share Posted January 17, 2017 .. and also putting the front half back onto the rear half, note the carry through tubes that someone was concerned about. Also note there is a substantial outer joining plate not shown yet. 4 Link to comment Share on other sites More sharing options...
Marty_d Posted January 17, 2017 Share Posted January 17, 2017 A question re the wing box - given that the box itself is full spar height over its length, wouldn't the spars be stronger being full height all the way to their end? Or is there no strength difference because the sum of the spar and box heights anywhere along the taper is the same as the spar being full height? 1 Link to comment Share on other sites More sharing options...

There is no loss of strength tapering. Besides ease of locating, you gain secure, zero clearance fit that strengthens the sum as a whole, you can not have zero clearance fit with parallel spars (without mechanical devices). 1 Link to comment Share on other sites More sharing options...

bexrbetter Posted January 19, 2017 Author Share Posted January 19, 2017 Pretty much the same as Hugh Lorimer's Sgian Dubh Similar, not same. I had actually designed a few different taper methods earlier before seeing that in the Sgian Dubh thread, and I did refer to it again last week for some thought inspirations. No, it's upside down... No, mine's the right way around. ... and that's when the fight started ... 2 Link to comment Share on other sites More sharing options...

bexrbetter Posted January 19, 2017 Author Share Posted January 19, 2017 So this is what the wing is looking like (in progress), note I use a folded C channel shear web, besides a little added strength, it's main function is as a jigging entity that keeps the assembly dead straight ... Annoyingly the rear turtle deck front skin was a little too short (25mm/1") and I had to make a new one. So I decided to make it just one piece and rivet to the spine as you can see here. Good thing is the entire rear turtle decks and tail can be assembled on a flat bench or floor in one piece as you see here then simply added to the frame as the one piece, of course I've set it up so that's all also self jigging. It's darn easy. 6 Link to comment Share on other sites More sharing options...
