Hey all,



The little alu fairings that go under the empanage that are screwed to

the fuse upper angle.



The plans imply that you countersink through the fairing into the skin

and angle. As the fairing is only 25thou thick, the C/S will open up the

hole quite a bit. My tempatation is to dimple the holes for the #6

screws and then C/S the fuse underneath.



The probem is that the C/S would then have to be deeper and I'm a little

nervous of cutting a c/s too far into the angles as these are structural

elements.



What did others do?



Thanks



Frank

I used a #40 drill and dimpled the fairing and countersunk the skin/angle and riveted it on.

My bad!  I thought you meant the empennage fairing, the fiberglass one.



Pretty sure I dimpled the gap cover and c-sunk the fuselage.  I'd be very 

tempted to rivet it on, but then you can't change the rubber seal easily.

Acually I did rivet it on and kinda forgot the rubber seal.



Thanks all the same...

And then made a classic mistake...



In the QB kit you have to drill out the rivets for the gap fairings...No

biggie but one went a little oversize...No problem I thought, that's

what "Oops' rivets are for....Could have gotten away with a standard

rivet but I have the oops so why not...drilled one hole to #30 and then

realised of course that I need a -6 rivet to get through the fuse side

and angle...Did I have one?...of course I stinking didn't, only -3.5's

and -4's...AAAARGH!

..

Do not archive or laugh at my idiocy!
