 Posted: Fri Jun 23, 2006 7:35 pm Post subject: Glareshield Installation |
 |
|
In the past year I have had occasion to have my glareshield out
several times for avionics and electrical work. Every time we put it
back in we have a problem getting the screws into the tinnermans that
tend to move out of line with the holes. Is there any problem with
replacing the tinnermans with rivnuts and using machine screws to
attach the glareshield?

Hi Scott:
Tinnerman's with floating 'C' clips. I feel it would be 10 times harder if
you converter the floating 'C' clips to fixed Rivnuts.
My suggestion would be to ADD a tool to your toolbox ... A scribe / awl. You
can use it to align the holes and provide a path for the screws. ALSO! Do
not tighten down the screws until you get ALL the screws in place. It also
maybe probable that the holes in the glare shield are not in the best of
locations. You may have to enlarge the holes to help in alignment, that is one of the
advantages of using Tinnerman's they can self-align if the holes allow. One
last suggestion, Start from the CENTER and work out in both directions. While
you are at it ... Make sure the center 'L' bracket from the firewall to the
panel is secure, they have a tendency to brake at the firewall connection.

Barry's suggestions work well. Another one is to attach the eyebrow
separately with maybe 3 flush screws (drill new holes and use Tinnermans,
etc.) and install the glareshield over the top of them using the original
holes and screws down through both glarehield and eyebrow. This helps
prevent the Tinnermans from moving out of position and makes it a lot easier
to reinstall the glareshield.

The tinnerrman clips I use are for the sheet metal, PK screws. They are a lot easier to install. It isn't structural so you don't need a locking nut.

Good suggestions. I use a hex head wrench.. They are tough and short enough to get into the corner.

I never have any trouble aligning the holes with the eyebrow attached with the screws from the glareshield. Plus, it makes it easier to pull the eyebrow and get it out of the way when I don't want to remove the glareshield completely to look inside. Also, if you have a plastic eyebrow (shame on you) it adds to the total time to R&R a light bulb.
