Rebel Building Question . . .
Posted: Fri Feb 17, 2012 9:59 pm
Hello All:
I have a couple of Rebel building questions for you.
1. I am preparing to rivet on the top tailcone (corner) wraps as
mentioned in the manual. I have drilled out the ALL of the holes in the
top corner wraps to 1/8 (including the ends of the wraps at bulkhead "B"
and "E"). I know that there will be some further drilling of skins that
overlap at those locations, but at the time, my thought was that since
the corner wraps were riveted, and I were to have left them #40 I would
have not been able to get at the holes at "A" and "E" to debur them
once the overlapping (top/final) skins were drilled to #30. I am a
little nervous that when I go to back drill through the existing 1/8
holes (through the flanges, corner wrap skin and new skin), I might
enlarge the existing #30 holes more than necessary. Is this the correct
way to do this procedure? Now that the holes are drilled, is it best to
use a strap duplicator in a situation like this ? OR did I screw up and
will just have to be very careful drilling of the #30 holes? Sounds like
a Catch 22 to me. (I hope this is a clear explanation on this one).
2. In Figure 12.27.5 Number 17 Rebel Manual. Do I drill out the existing
9 rivets at the side overlaps at Bulkhead "A" and lay in the "new"
bulkhead doubler (the one that butts against "A" that faces aft) and
back drill through those 1/8 holes then rivet through both? That would
make the gap between the 2 bulkheads go from 1/4 inch at the bottom to
zero at the top (sides)? OR make a 1/4 inch spacer and rivet at the top
(sides) so the bulkheads are parallel all the way.
3. What does it mean at Figure 12.27.5 "bend the new bulkhead over to
accomplish this"?
Thanks in advance for the comments and suggestions.
