Mounting slides for projection

[P3D Groose, Gary <GGroose@xxxxxxxxxxxxxxxx>]

I am now the proud owner of a new (used) Compco 500 projector (thanks
Peter!).  After testing many of my slides, all mounted in cardboard, it
is clear
that I need to more precisely mount those that I want to project.

What should I use for mounting?  Should I get RBTs for projection, and
if so, should they be the ones with glass?  Or should I get some
aluminum masks and go that route?  I think my primary consideration
should be a system that is reasonably easy to achieve precision
mounting.  But I am also open to suggestion on what my primary
considerations should be.

Thanks,
Gary Groose
