im looking for something to use to push up one end of a 7" LCD display and i
thought id use a linear actuator. Only problem is that all the linear
actuators I look at are huge, push 1000 pounds, and go way too far. Is
there anything else i could use that is small and inexpensive to get the job

How about using a small gearmotor to drive an allthread leadscrew with
limit switches at the extremes of movement?

more data please. a 7" lcd is pretty small. there ought to be a bunch
of possible solutions to your need.
does it need to be decorative?
how much travel do you require?
how must it be activated?
what are you building?
mebbe a spring loaded hinge, blum self closer type?
Years ago there was a line of small automation type cylinders that would
work if they are still made.
They were 1" bore, some used a spring to extend the rod, then you would
pressurize the rod end to retract the rod.
There were lots of other options but I have been away this kind of stuff
for a long time.

"Small" + "inexpensive" should never be used with "linear", Matt. ;)
Forget Leon's solenoid idea. It has a <1" range and is instantaneous,
far too quick for raising that much mass even if it could.
Try www.surpluscenter.com , search for "linear". For $35, the
#5-1437 looks like it'd work for you with a rail/lever system.
Try again next week and there may be more to choose from.
It takes Burden -days- to ship, so plan on 7-10 days overall, UPS.

The actuator I got from Graingers is shown on my web page
http://www.members.tripod.com/mikehide2/ . Look under desks and check the
large desk with the leather paneled top . there is a shot of the elevator
mechanism I built , the electric actuator is clearly shown in the center.
The linear actuator has an electric motor which drives a screw jack with
about 12 + inches of travel if I recall....mjh
