I use a Kwiklift in my shop as shown in the pic.
It's great for my shop but it requires jacking it up with a floor jack. That's not always fun with my lousy back. I've looked at air/hydraulic floor jacks but they're pricey. I've wondered if I could use an air/hydraulic pump
like this: http://www.harborfreight.com/10000-p...ump-98318.html
to convert my floor jack to an air/hydraulic jack. I'm not sure what this would involve or what I should be aware of. I was wondering if anyone here has any advice or expertise.
