This is a really nifty design. It can be hydraulic or manual. I like
the feedback from a manual, but the hydraulic ones obviously have more
pressure. If I can get it to download right (doesn't come in all the way
before something goes wrong or it says its done). I'm still trying. I
wonder what the rating on that design is, because while my idea doesn't have
the versatility of that one, it is stronger (time to hit the sketchpad
again!)
When I start dreaming up these things, the cost doesn't really figure
into it at first, because often times I come up with something that I think
is better, then put it on my list of stuff to do later, given the resources
and time. Years ago when I lived in a tiny two bedroom house with no
garage, I made two funny looking sawhorses whose original purpose was to
hold an engine at the right level to get it on and off the stand, as I
rebuilt the engine in the other bedroom. They cost me a bit more, but the
versatility and space provided was just what I needed for awhile after.
