Steve,
In addition to the mounting
brackets you bond to the side of the fuselage, Lancair recommends one support
bar attached between the plane and the top center of the backside of the
panel made from aluminum tubing with the ends flattened so you can put a bolt or
screw through them. I don't recall the chapter,
but it's in the manual.
When I did this I found that the upper
sides of my panel could move (flex) quite a bit. To fix that I added two
additional support bars that attach to the panel on either side of
center just before it begins curving down. All three of the supports
are anchored on the shelf behind the panel and I have countersunk #10 phillips
screws attaching them to the top edge of the panel. Countersinking was
necessary so the screws didn't stick up and interfere with the
glareshield. I believe I put nutserts in the panel ends of the supports
and used AN-3 bolts on the shelf ends. My panel is rock solid with this
configuration. Sorry, but I couldn't find any photos of the back of my
panel to illustrate this for you.
