The VS instructions specify that only the top portion of the 410 bracket
(bottom rudder hinge bracket) have all six of its holes drilled. The bottom
portion has the two lower corner holes undrilled/punched stipulating that
these holes will be drilled for bolts in assmy with fuse and refers you to
dwg 27a (RV7A). In examining 27a I see that the bolt holes do not coincide
with the rivet holes but are inboard. There is also a note referring to
rivet size for the corner holes and an instruction to dimple/csk the
spar/doubler.
Is 27a incorrect? There is no way to dimple/csk the spar/doubler assmy after
it is riveted so either these holes are drilled now with the dimple/csk
process or not at all. The instructions that the corner holes are drilled
for bolts make sense but this isn't what 27a shows.
Anybody else seen this problem?

Joe,
After taking a look at this, the way I read the drawings is that the
lower corner rivets are actually used just for the nose-dragger
version (7A). If you're building a straight -7, then you install the
bolts in the lower corners (slightly offset inboard using the
tailwheel mount as a match). Basically, do one of two options. So if
you're building the 7A, drill for, and install the rivets. I can't
see why you wouldn't go ahead and drill and rivet these two lower
holes at this time as there doesnt' appear to be anything the depends
on these with a -7A. Just my opinion and is worth exactly what you
paid for it....<g>

I'm building the 7A. I believe I used the top bracket as a guide to
drill the holes for the lower bracket. I then went ahead and
installed the rivets in the lower bracket.
I don't know about the taildragger but I belive the bolt holes are
spaced differnntly than the rivets would be.

The holes on the forward side of the VS spar are dimpled so the spar
can lay flat against it's mount on the fuse.
If your building the 7A you'll dimple and countersink before you
rivet the lower bracket in place.
If building the 7 the lower bolts for the tailwheel go thru the lower
rudder bracket and are drilled in assembly with the fuse. So those
holes would not have to be countersunk.

Thanks to all who replied. After reading the opinions offered and looking at
the plans again, it seems clear now that for the 7a you put in the corner
holes/rivets.
Thanks,
