EarlyBird Posted March 5 Author Share Posted March 5 Thanks John. Second side of the elevator now complete. I have not decided on the joiner, just testing and thinking. While I am thinking I can move Peggy Sue II on. Steve 1 Quote Link to comment Share on other sites More sharing options...
stu knowles Posted March 5 Share Posted March 5 Think that I would put a servo on each half for a bit of redundancy. Nice woodwork! Thanks for posting, always interesting to see another persons build 1 Quote Link to comment Share on other sites More sharing options...

Thanks stu, I was always good at woodwork when I was at school, and it must be like riding a bike in that you never forget. A big thanks to the Forum and its members because without it and the interest shown I probably would not be building; I agree following others builds is interesting and often informative. I must get Hound Dog ready for its maiden and finish Peggy Sue II, The Ohmen is also in the Queue. I will keep posting. Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 20 Author Share Posted October 20 October weather arrived today in the form of a storm. The mighty barnstormer wings have been started Not much to show but lots of thinking. The bottom spar is not square and will need packing up by 0 5 mm on the back edge and 1 mm at the front Interesting,👍 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 21 Author Share Posted October 21 While thinking I have been preparing the ribs by making the spars fit and removing some of the burnt wood, more will be removed as the wing progresses. Quote Link to comment Share on other sites More sharing options...
John Rickett 102 Posted October 21 Share Posted October 21 Steve, the lowest part of the ribs do not have to touch the board while building. If you pack each lower spar using something like 1/4" balsa, it will be fine. Just make sure that the spars seat fully into each rib as you go along - a straight edge dropped into the top spar slots will help here. 1 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 21 Author Share Posted October 21 I've decided to follow the Peter Miller method as close as possible. I've taken two shavings off the front of the bottom spar. Here's a picture of the test setup. looks good to me.😊 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 22 Author Share Posted October 22 It's not obvious how to fit these. I am used to the dihedral braces being fixed to the spars or boxed in between the top and bottom spars. Quote Link to comment Share on other sites More sharing options...
Nigel Sharp Posted October 22 Share Posted October 22 Looking at the plan. The one for the main spar is bonded on the aft side to the vertical webs also on the aft side. The other is bonded to the front of the rear spar, the plan I'm looking at is on outerzone. The barnstormer has struts... which can be made to carry flight loads so those braces wouldn't need to be massive in my opinion. Since the side view doesn't show the bracds against either the upper or lower spar. I would probably bond to the lower... that way it is invisible from above when covered. But you could make your own to go between or to suit the height over the spars if you wish. Thats a positive for plan building modify to suit your preference.

EarlyBird Posted October 22 Author Share Posted October 22 Thanks Nigel, I was thinking of cutting the braces in half length ways to make two that would be bonded to both spars That is how I have learned to do it and has become my preferred method.

Nigel Sharp Posted October 22 Share Posted October 22 It's the depth of the brace that gives the bending strength... it acts like a beam. I'd be tempted to leave it as is. But you could make a second from scrap ply if necessary. 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 22 Author Share Posted October 22 (edited) Thanks again for the most helpful explanation I will do as you say. Braces at the bottom. The two ribs need slots cutting to take the braces, which is the reason I am thinking about it now. Edited October 22 by EarlyBird Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted October 22 Share Posted October 22 You do know there are multiple build threads for barnstormers in the 2014 mass build ? Might possibly be useful? Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 23 Author Share Posted October 23 Thanks Jeff, it's good advice to research past builds, they can be found here https://forums.modelflying.co.uk/index.php?/forum/24-the-2014-mass-build Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 23 Author Share Posted October 23 With the spars packed up by 1/16" and 1/32", for the rear and front spars respectively the tip rib is glued in place. Looks good to me 😊 Quote Link to comment Share on other sites More sharing options...

Nick Cripps Posted October 23 Share Posted October 23 Steve, there are vertical grain shear webs glued to the rear face of the spars. The dihedral braces are glued to the rear of these shear webs. Quote Link to comment Share on other sites More sharing options...
Nick Cripps Posted October 23 Share Posted October 23 I've just looked again at the plan on Outerzone and realised that my previous comment applies to the front spar position only. For the rear spar, there is a note on the centre section stating that 1/4" balsa is used to infill between the spars to bond the dihedral brace to. 1 Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 24 Author Share Posted October 24 Thanks Nick that makes sense. Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted October 24 Author Share Posted October 24 I've been preparing the shear webs and test fitting. Next will be to cut some holes in the ribs for the aileron wire then the ribs can be glued in place. 2 Quote Link to comment Share on other sites More sharing options...

EarlyBird Posted October 26 Author Share Posted October 26 (edited) That's the only way Ron. I have made the cabane plates, I've nearly run out of things to make, and it struck me that the rear cabane plate is glued to the centre sheet. Hmmm it would be a good idea to add the sheet now I thought, as I am not following the build sequence, what could go wrong? Now I am at the wing root I am having more thoughts about the dihedral brace locations, which is good brain gym. Thinking does help. Next 🤔 Edited October 26 by EarlyBird Quote Link to comment Share on other sites More sharing options...
