I have this tool that I like to sell, but I can't figure out how the darn
square blocks move. It has that turn dial with handle for it, but I can turn
and turn and turn, nothing happens. This instrument looks great, and nothing
is broken or anything visible. The only thing it has missing is the top
screw that holds down the dial cap or whatever they call it. I found a screw
with the same thread, and tightened it just a little, but still nothing
moves when I turn it. Any help is appreciated. I can't find any help on line
anywhere......BTW I'm selling or trading it for 175.- just in case someone
is interested. I'm in the Sacramento area
