P.o Prune Posted January 9, 2018 Author Share Posted January 9, 2018 @Fozzy: I have thought about buying some balsa and make a brand new frame. But I'm worried that the cut-outs for the longerons won't match the other frames. I've tried doing something else.. Will post a new update soon. @Army_Air_Force: I did use a round sanding drum to shape the inside of the frame (former) As for the cut-out I used a scalpel, maybe I should have used the mini drill.

P.o Prune Posted January 9, 2018 Author Share Posted January 9, 2018 Just to make matters worse the top of the frame broke too... This hasn't been my lukiest of days Using araldite (is that what you call it too?) I glued the two parts together and clamped them. Then I installed the frame in the support and clamped them down too while the frame dried. All well and dry, and it looks, and more importently, feels quite solid. And then I got struck by a flash of genious... I was going to strengthen the frame to make sure no further disaster was going to surprise me. At work we have stirring pins (too cheap to buy teaspoons) so I "organized" a few of them. Efter careful studying I selected on and soaked it for a day or so. I then gently bent it into shape and "tied" it up before letting it dry: Yes, I know... it doesn't quite fit, but don't worry. Hoping that I wouldn't damage the balsa I soaked the stirring pin again and then very, very gently formed it into the fram and clamped it down leaving it to dry. Looks pretty good to me. Next step is to glue it into place which should eliminate the space between the frame and the top of the stirring pin. All glued and set to dry. I'll leave it like that for at least 24 hours. (I did correct the stirirng pin a little, managing to make it more in alignment with the frame.) Link to comment Share on other sites More sharing options...

P.o Prune Posted January 11, 2018 Author Share Posted January 11, 2018 Trust me, I was very tempted to do just that. But in the end I figured that I would get a more precise frame by repairing the broken one. That being said, I intend to go buy some balsa just in case...

Army_Air_Force Posted January 11, 2018 Share Posted January 11, 2018 (edited) If you're buying balsa, get 1/16 or thinner sheet, and laminate two or more pieces cross gain to make a light ply. Even better, get 1/32 or 1/16 birch ply and laminate them. Edited January 11, 2018 by Army_Air_Force Link to comment Share on other sites More sharing options...
