The simplest and most effective focusing device that I have made 
was done by the following method:

Take a small 15X loupe with a plastic base and grind/sand down the 
base until the ground glass is in focus when the loupe is in contact 
with the back side of the glass.  That's it.  I don't think you want the
magnifier to be adjustable, unless you have an unusual situation.
