Hi all
Hope all is well with you.
The weather here in TX is finally cooling off so I've been working away on my
lancair 360 slow build . I've got the main and aft spar in and have a few
questions about the belly pan install.
My questions are. Does the belly pan get bonded flat against the main spar
. It has a bit of an arc in it but could easily be clamped flat to the spar,
also does the pan run parallel to the main spar ? meaning at the ends of
the main spar your lap over the spar with the pan is about half the width of
the spar. Mine if i make the pan parallel to the spar my rear fillets don't
match real well 1/4 gap on one side.see fig 5. Does the aft spar rest on the
foam core in the belly pan and does it run parallel to the aft spar exterior
of the fuselage area .?
Is there any foam rib on the spar where the pan meets the main spar at bl 50
,or is that to be removed prior to bonding on the pan. The instructions are
very vague about the whole pan process but do say that the pan and main spar
are not for alignment purposes.
I guess what I'm asking is, is my main spar to far fwd, is it angled to far
in one direction, my measurements confirm that it is perpendicular to the fuse
IE tip measure to outboard spar ends.
Is it better to have the pan run more parallel to the spar for good bonding
and just fill in at the gaps between fuse and belly pan? at the rear end see
fig 6 this gap is present when the pan is more parallel to the main spar.
Or is it better to have the rear joggle be perfect and the joints out board
of the joggle be perfect and not worry about the alignment of the pan to main
spar knowing that the top skin will bond to the main spar and the belly pan
making a good connection to the spar?
I am not opposed to cutting out the main and aft spar to achieve a better fit
but my measurements imply that its where it belongs. I feel like after the
pan is installed the spar is where its going to stay. Sooo No further
progress is being made cause I'm not going to screw up this part without
someone elses input.
Thanks for all responses I feel like I'm at a point of no return if i bond in
the pan and its wrong. I want the confidence to proceed with this so any help
will be greatly appreciated.
Hope to hear from you
