1 Oct 04 - Finishing the Landing Lights
The only thing that is left to do on the lights is to get the plexiglas attached
to the wings - the lights are already mounted and the plexiglas has already been
cut to the correct shape.
this is the first time I've drilled holes in plexiglas, so a certain amount
of experimentation was necessary before I started working with the actual parts.
Drilling plexiglas wasn't as difficult as I thought it was going to be - just
go slowly, and don't drill a large hole in one go - drill a small one, and then
make it larger later.
The tape "handle" you make for drilling the holes in the plexiglas - used to hold
it in place when you match drill the holes.
Plexiglas with the metal strips/nutplates on. This is held to the plexi with
double sided tape.
Same thing - just a view from the other side.
There's the finished product. The fit is pretty darn good!
These are both good things to have. Why? Keep reading.
I'd like to take a minute and rant about how cool Boelube and Goo Gone are - I
ended up using them both during this phase of the project. Let's talk about
one at a time:
- Goo Gone - this is a good thing to have because if you make a tape
handle to hold the plexiglas in place while you are drilling it, eventually you are
going to have to get the tape back off of the plexiglas. The tape that we had
left sticky stuff all over the plexiglas, and Goo Gone is (not surprisingly, given
the name) designed to take sticky stuff off of other stuff. It doesn't do anything
nasty to plexiglas (I tried it with a piece of scrap first), and this is what I
used as I didn't have a plexiglas polish. This worked great.
- Boelube - this is also pretty amazing stuff. You'll want to use it for
putting screws into nutplates all over the airplane, but I think it's especially
important on these ones. A little back story first - the nutplates that are used
on the RV are made to be a not completely circular. The idea behind this is that
it keeps the screw from vibrating out once you've gotten it in there, but the
unfortunate part is that it's a real pain in the tush to get it in the first time
without stripping the screw or gumming up something. Boelube keeps you from stripping
the screw and generally makes your life lots easier.
You'll want to use it on nutplates all over the airplane, but on these it's
especially important because if you don't get the screw started when you want to,
you can end up pushing the nutplate away from the plexi, because it's just held
on there by tape. (Yeah. Ask me how I know this.) The end result is that
you'll push the little metal strip off of the plexi, it will fall off, and you'll
have to take apart the entire mechanism reattach the plexi to the metal strip.
Boelube will make this easier, I think, but it also helps if you have the screws
lined up (duh) and you can use clecos to hold in the ones that don't yet
have the screws in there.
