Greetings,



I'm building the jig to bend the trailing edges of the elevators on my RV-7A.  

Does anyone know the correct bend radius for these trailing edges?



Thanks,



Mike

I used an 1/8 inch wood dowel. I did tape the dowel in so it wood remain in 

position. and I also taped the bottom edge of the elevator to the bending 

break. I also couldn't believe how much  force)it took to get the edge to be 

straight/true/and the correct radius.

 No pun intended?  Got wood?  Do not archive.

Mike, if you want a nice flying airplane in pitch feel use a 1/4" dowel.  The tighter the radius, the heavier the airplane will be in pitch.

 Mike,

  

 On Drawing 4pp it shows 3/32 as the minimum bend radius.  This was for  .020 skins when I built mine about 5 years ago.  Actually, I didn't put  anything in to maintain that radius.  But I did have a little trouble with  the stiffeners limiting the travel.  As a result the skins are not as  smooth as they could be.  I made my "brake" out of some old door jambs and  hinges.  It seems like it would be hard to keep a dowel in position.   Let us know how it works out, please.
