In the 51 years we've been married, Naomi and I have hardly been apart
more than few days at a time.

However my planned trips to SE Asia and elsewhere present some
logistics problems...

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.

Larkin should butt out of the conversation and tend to his carpal
tunnel from emulating Anthony Little Weiner ;-)

Interesting lift system http://samsreef.com/content/view/19/2/

Drawer slide mounted on Top, that slides out (horizontal) for some
leverage?

Block and tackle to ceiling?

Gas charged lift support? (automobile stuff, you need to mount inside
hood. This could work well.)

Cheers

Indeed! I hadn't thought of lifting the whole hood, but maybe that's
a scheme to consider... my tank is 250gal.


Drawer slide mounted on Top, that slides out (horizontal) for some
leverage?

Block and tackle to ceiling?

Thought of that as a temporary fix. There is an A/C duct about 12'
off the floor from which I could attach. (This is in the Great Room,
16' ceiling.)

No room there. Next time around ;-)

I don't know how you'd make this look good, but the idea is:

=============Lever================
----------------------- ^
Hinge| |lid |
----------------------- lift here

A lever affixed to the lid.

Another possibility is two large screw eyes in the lid, into which
you can slide a dowel for the lever when you need to lift the lid.
That way, the lever does not have to remain affixed to the lid.

Next, not easy, and not usually applicable, but maybe possible:
If it is possible to drill a deep hole into the thickness of the
lid - depth say 4" - you can insert a dowel when it is time to lift
the lid and get a nice force multiplier. That of course depends on
the thickness and strength of the lid, but if it is do-able it doesn't
change the look of the aquarium.
You need a *really* strong lid - drilling into the thickness weakens
it, and the dowel exerts force that will split it, unless it is real
strong, or reinforced. One of the hopeful things here is that you
have attached lighting (presumably below the lid, shining into the
tank). The fixture itself could possibly hide an under lid reinforcing
plate. However, you would still need reinforcement on the outside
of the lid to prevent splitting - or a very strong lid that won't
split when lifting with a dowel inserted into its thickness.

How tall is the lid?

- A loop in the center, permanently affixed, to shove a stick into.
The longer the stick, the less lifting effort, but the larger the
travel.

- A smaller hole or trap in the lid to drop pinches of food through.

Not easily. It'd require pulling the hood, and all its light wiring.

If there's low friction, and room behind, a counterweight that puts the
lid center of gravity slightly above and on the lid side of the hinges
should work out well -- it'll take slight force to open, it'll tend to
stay closed, and once it's opened enough it'll _stay_ opened. As long
as it's not bonking into a wall, it should be perfect.

Put some gas shocks on the lid! you only need to a fish scale
to measure the needed LBS to pick up the lid..

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.

I'm going to cut a hole in the lid and fit something like a "desk

Somewhat late, but a wire torsion spring has a low profile, and seems
well suited. you'd need one with the correct torue to support most of
the lids weight when deflected 90 degrees.
you could possibly put the spring through the higes instead of the pins
bending one end along the edge of the hood and the other (after running along
the hinged seem the apropriate distance) across the lid will reduce
the stress on the woodwork.
