Anyone know of links to various hydraulic mechanisms or systems? I'm thinking of something that is manually operated, not driven by a pump. Thanks.

I just spent a bit of time searching out the same topic for making a bandsaw hydraulic cylinder but no luck. What you want may be available at Tractor Service Supply. I found a fairly informative brochure there some time ago.

Do you mean small non-powered hydraulic systems....? We might also call them hydro-static systems.
Yes there are a few around for various purposes, but if you are trying to move or control anything with any force or precision, there are difficulties.
I recall a local company that spent years & $$$ trying to develope a hydrostatic, manual marine steering gear....this was to replace the usual Teleflex type cable systems used on boats all over the place.
Leakage & the slight compressability of oil are two factors to consider for precision control, as is the input power vs. actuation force required.
Hope that gives you a start...
