Posted for "F. Barry Knotts" <bknotts@buckeye-express.com>:
Working on my nose gear doors and I've discovered I have less that
complete information about this assembly. For those who have been
there, a couple of questions:
1. I'm joining dissimilar metals (hinge and rail,
hinge and door) and similar metals (door and hat stiffener). Should
they be treated (Scotch brite, aluminum cleaner, alodine, self etching
primer) BEFORE assembly? For that matter, should they be treated after
assembly at all?
2. The opening in the fuselage that is covered by the
gear doors at the nose gear tunnel is not rectangular. The aft portion
was gracefully curved at the factory to just admit the wheel and tire.
(Attached image-Note that the fuselage is upside down and the nose gear
is in the fully retracted position with one gear door in roughly the
correct position.) The manual describes rectangular doors, but doesn't
mention the hole in the fuselage. Should the doors be fitted to the
rounded back end of the fuselage cutout or should the cutout be extended
into a rectangle leaving the doors squared off. A third possibility is
to allow the doors to close over the remaining aft portion of the
fuselage, building up the area behind the doors with micro bodywork to
form a pocket, thus eliminating the need to make the aft closure stop.
3. Bob Pastusek also mentioned the alignment of the
gear with the centerline when retracted. My gear is 3/32" off of
midline when fully retracted at the level of the top of the fork for the
wheel. Is that too much? The fix is quite an undertaking (overboring
the mounting holes) so I'd like to be sure that this amount of
misalignment is not going to be a problem later. Any thoughts, Bob?
Thanks for your help.
