I'm considering ripping the curved tube out of an aircraft bank

There's a bicycle bubble level on the market but I don't think it's a

good design.

My question is, on aircraft bank indicators, why do they look like
they
are about 6" deep? What is in this rear of the instrument? I'm sure

there's a light bulb in there but this does not explain it. Perhaps
there's more to it than a steel ball in a tube?

Thanks for your help.

Bruce;
Go to your local Wal-Mart RV Dept. (IE; trailer / motorhome ) and
find several levels of the type you want. They are used on trailers to
level the trailer for camping. They will be better for your purpose
and much cheaper,probably.
The aircraft T & B has a gyrpscopic mechanism in the rear part-
expensive .
