My wife is petite, 5'1", and I need some way for her to lift this
lid...

http://analog-innovations.com/SED/AquariumLid.pdf

to feed the fish in our sal****er aquarium.

Very heavy, with attached lighting. So heavy it stresses my own
rotator cuffs :-( Recessed, so, right now, I lift it first with my
thumbs.

Any ideas? Maybe a lead screw? No room inside the hood, so it needs
to be external.

Cut a hole in the lid.....



Also a good suggestion... use one of those desk "grommets" to get the
SWMBO Seal of Approval :-)

power driven hinge shaft on the back of the lid.
5 rpm 90 degree worm gear drive motor that couples with the
hinged shaft to open or close it under power.

P.S.
We've done this before only we used a ratchet gear with ratchet claw
so one could simply pick up the lid by hand instead of under power. This
was on a large glass enclosure for a snake. To lower it , it had to be
done via power and of course you could raise it that way if you wish..
the problem was people were dropping the lid when the snake scared them
and some times cracked the glass.

Just a thought.

P.S.
you most likely would need some one that is partially machinist
talented to help you.
