Naysayers,
Your replies are not well thought out. You apparently just want to be negative. You may have a basic understanding of hydraulics, but you pick parts of my statements to make a point, and ignore any qualifying language.
Only one example: My qualifications were that I needed to lift 700 lbs. in MORE than 1 second. I never set a top limit, but suggested 2 seconds was also reasonable. I KNOW there is enough fluid and enough mechanical advantage in a 2 ton bottle jack to lift 700 lbs 3 inches in two seconds. Anyone that can think will also know that.
4000/666 ~ 6. 666 is close enough to 700 and I want even numbers.
If I pivot a lever at one end and place my 2 ton bottle jack under the lever at the 1 inch point. (for the **** retentive I'll substitute a knife edge for the jack anvil.) Now I'll hang a 666 lb. weight at the 7 inch point.
Result if the bottle jack moves 1/8 per each "pump" of the handle with the 666 lb. the bottle jack will then move up 1/2 inch in 4 pumps of the handle. Since the lever has a 6-1 mechanical advantage the 666 lb. weight will move 3 inches. I can easily pump that jack 4 times in 1 second. My grandmother can probably pump it 4 times in 2 seconds.
If the jack ram will only move 1/16 of an inch in one pump then I can do the job in 2 seconds.
All that hoodoo voodoo math you've been throwing at me is wrong. Maybe grounded in truth, but mistakes were made. And don't be telling me that my example is not relevant. Work is work(scientifically). If the jack will do the job with the lever it can be configured to do it mostly hydraulically. I knew it would work when I asked the question. I didn't ask if it would work, I just wanted someone to look at what I was doing to see if I left something out. Not sure I explained the situation properly as few have indicated they understood what I wanted to do. That would be my fault.
