EarlyBird Posted December 21, 2023 Author Share Posted December 21, 2023 A ruler helps to position the sheet. Damp the top of the sheet to help it bend and while it soaks in apply the glue, no rush, then lay the sheet in place and hold down with weights. I used a 600 mm Permagrit for the leading edge, with the rough side down it stayed in place even close to the edge. After a few minutes I moved the ruler and used 1/16" scrap to balance the wood block and batteries close to the back edge and the Permagrit as far forward as possible, adding a bit of hand pressure just to make sure. Here it is with the weights removed. Looks and feels good to me. Top cap strips next. Steve 2 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted December 23, 2023 Author Share Posted December 23, 2023 Sanded LE and tip rib then set up a 1/4" jig. Using a piece of 1/4" spruce for the width of the cut. The length of the cap strips was a consistent 119.5 mm so I cut a piece of scrap 1/16" exactly to this length then used the jig to cut eight strips and glued in place. and after some sanding here we have it. I must be learning. Next, I cut the bottom strips and at that gave up for the day. Steve 1 Quote Link to comment Share on other sites More sharing options...

EarlyBird Posted December 25, 2023 Author Share Posted December 25, 2023 A lazy day yesterday as I only managed my minimum target of adding at least one piece every day. One cap strip. Today I am working on the servo mount as a start, hopefully. 🙂 Steve 1 Quote Link to comment Share on other sites More sharing options...

EarlyBird Posted December 28, 2023 Author Share Posted December 28, 2023 Bottom finished, at last.🙂 and second wing started. I am wondering what to do as I am ahead of John (@bodgerupep). Steve Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted December 28, 2023 Author Share Posted December 28, 2023 @bodgerep another mistake from me.😭 The first was assuming the ribs were flat between the two spars. Steve Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted December 29, 2023 Author Share Posted December 29, 2023 Bottom spars I should have said. Ribs and top spar done. Steve 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted December 30, 2023 Author Share Posted December 30, 2023 Bottom pulled up and LE fitted. Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 1 Author Share Posted January 1 Alot of shaping and fitting over the last few days. Starting with the LE and top spar then the TE, I use the David Plane to start, just catching the ribs. Then use the Perma grit block to finish, again just catching the ribs and removing the burnt wood. We now come to the tricky bit of joining the wings. With the wing propped up 1 1/2" then the join is test fitted. TLAR, after lots of careful sanding and test fitting. Next is to glue it together then finish the top LE and the rest, including the cap strips. Steve 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 4 Author Share Posted January 4 First finish the shear web. Then set up for the LE sheeting. and all done. Steve Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 9 Author Share Posted January 9 TE is next so add the scrap balsa first, Then using the LE offcut which will fit perfectly. or maybe not, I must have cut the wrong side of the line. 😞 Only thing to do is cut another one. and use a ruler for a straight edge so that the rib cap strips are 119.5 mm to match the first wing.

EarlyBird Posted January 10 Author Share Posted January 10 (edited) Which brings us to the top centre sheeting. I make this from two pieces of balsa fitting tp the LE and TE respectively. Then using a sharp pencil mark the cut line. Cut on or to the correct side of the line. Edited January 10 by EarlyBird Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 11 Author Share Posted January 11 I check the fit and when happy (TLAR) tape the top. Turn over and tape the full length which will form a hinge. Turn over and remove the temporary tape which will enable the hinge to be opened for glue. When glued it will look like this and fit, we hope. On the back draw the lines for the desired shape. and cut. I also score along the centre line. When happy glue it. Steve 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 12 Author Share Posted January 12 All joins will be invisible. 🤐 Steve Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 12 Author Share Posted January 12 Next is the bottom sheeting but first the paper tube, Then repeat the process used on the top sheeting. The hinge opened up and glue applied. Close the hinge and wipe off the excess glue then place on a flat surface and weight down with anything heavy and to hand. Soup for lunch now I have taken it out of the cupboard above, which was to hand. While the glue dries I can have a cup of Tea. Steve Quote Link to comment Share on other sites More sharing options...

EarlyBird Posted January 14 Author Share Posted January 14 When dried sand the outside face so that it 'will' be invisible when covered.🤣 Then as previously mark and cut, when glued here it is. Steve 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 17 Author Share Posted January 17 The bottom is now finished. Just wing tips, LE and TE to do.😊 Steve Quote Link to comment Share on other sites More sharing options...

Ron Gray Posted January 22 Share Posted January 22 Very neat Steve 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted January 22 Author Share Posted January 22 Thanks Ron, I try to be neat. As no one has asked why I build the wing first I will say anyway.🤣 I use the fuselage ply doubler as a template. a bit more work required obviously.😊 Steve Quote Link to comment Share on other sites More sharing options...
Nick Cripps Posted January 22 Share Posted January 22 My building order is usually tail surfaces first (to ease myself back into building) followed by the wing and then the fuselage. I love building wings but hate fuselages so they always get left 'til last! 1 Quote Link to comment Share on other sites More sharing options...
