Reply to "Elevated test track Rollers for any roller design"

cool beans!  another lab jack use.  I have one very similar that I use for raising and lowering my router in my router table -- about as good as one of the expensive dedicated devices and a heck of a lot cheaper.  Your seems to raise the jack when turning the handle clockwise - mine is the opposite (which seems counterintuitive).  Hmmm, I wonder if its simply a matter of putting the handle on the other end of the screw...!
