Pneumatic toe pincher

About how much PSI is needed to lift a lid that is somewhere in the ball park of 10-25 lbs? I am looking at this small and cheap air compressor from Harbor Freight in order to power the prop. Link below to the compressor!

If there's not a lot of air draw and the time between cycles is fairly long, that little compressor might work fine and you can always add an external tank. Harbor Freight Expansion Tanks

Also, are you going to open the lid from fully-shut to full-open? Or, will it be more like the MIB with a jumping/banging lid of just an inch or so? If it's the latter, there are some good examples here of folks using motors with grapefruit-sized cogs that have random cuts in them to simulate random get-me-outta-here banging of the coffin lid.
