I think I see.  The previous msg was the magic spell though, and I now 
have that 20 lines of code doing as it is supposed to.  And I have 
relocated the x offset from the jig, to the left edge of the guage 
blocks on the jig, but haven't recalibrated the Y offset just yet.  
Thats tomorrows project, while I am mulling whether or not I make the 
jig, either air driven to bring it in or out, or, if I can figure out 
how to drive a cdroms tray motor to flip it down or up electrically.

So I'm going to go rooting around in the fleabay midden heap for a 
suitable 12 volt air valve and a mini air cylinder.  I have 80 or so psi 
in the garage, so a 1/4" double action cylinder, with a 12 volt driven 
spool valve seems like the simplest way to automate it.

Thank you Andy.

Cheers, Gene Heskett
