FW: [Wing] flap attach

[Barry Tunzelmann]

Pat, the more modern instructions that I had for building my 6 (circa 1998 
- wings) had us install the flap hinge pin in one piece from through the 
inboard aileron bracket. The hole that you drill through the bracket is 
slightly offset from the hole line looking through the flap hinge. This 
prevents the pin from working out back to the ailerons. So big deal, you 
have to undo the aileron to get the flap off and that takes an extra 5 
minutes. Don't know why Van suggested this way, may be better to have one 
pin instead of two. I live in Salmon Arm but work during the week in 
Calgary so if you want call me and I will come over and show you what I 
did. My number here in Calgary is 234-9003

Pat;

As others have said, this is the usual RV-6 builder's solution and, in 
fact,
is what I did. Works just fine once the hinge pin is in place.

One caution is to make sure the hinge pin comes out and goes in fairly
easily. By this I mean keep the hinge line straight and spaced to allow the 
flap to rotate to at least 60-70 degrees from streamlined. Apply a suitable 
lubricant, make sure the hinge eyelets stay clear of paint and do not get
damaged when riveting the hinge segments to the wing and flap.

Situation is that due to the way the forward curved upper surface of the
flap contacts the top wing skin, you will not have much access to the flap
hinge to insert a long, flexible, pin. It helps to be able to lower the 
flap
to as close to 90 degrees as you can get it but this will show up any
misalignment in the hinge. "Retracting" the flap allows the pin to move 
more
easily but then you have no access!

In extreme situations, some sort of arrangement with wooden guide sticks 
and
such will be needed to get the pin to slide into place but once you have 
the
wings on the fuselage this won't work. A couple of helpers when bent nose
longnose pliers and many #$%& words can be needed to persuade the pin into
place. As in a lot of places on an RV, a friend with skinny fingers about 8 
inches long would be really nice to have. (Have you done the wing bolts yet 
? Are you building a -6A for the extra fun involved here?)

This is not to discourage anyone from using this method, just to forewarn 
of
some of the potential problems involved.

Good luck and happy building!
