I've got say I have picked up a lot great ideas for my shop from you,steevo, and jack olsen. :bowdown: and there is only one way to go (completely overboard)

you could do 2 hydraulic lift cylinders connected to a small hand or foot operated hydraulic pump. the pump I had in mind was something like off of a B-4 maintenance stand used by aircraft maintainers in the USAF. or 2 bottle jacks that are pumped up by air instead of by hand
