Projecting bare metal mounts in TDC

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

Mike K. FYI, I use cardboard mounts and do not get any jamming in my
TDC.  In Detroit they project about 80 slides from some 35 different
entrants every month in their slide competitions with a TDC.  I rarely
see any slides jam and they don't mess up with horizontal/vertical
alignment, only focus.  This is the way it should be done, IMO.

But the following is of great interest to me because I first mount
all my slides in Albion aluminum mounts and do all my projection
previwing while they are still in this mount so I can decide which
ones to mount in carboard, RBT or aluminum/glass.

Here is what I do:  I have two sets of projection glass mounts (each 
consisting of two pieces of glass tapped together in one end only)
I slide the aluminum mount in the glass sandwich and feed it in the
projector.  This pushes the previous one out and I remove the previous
slide and put the next one in.  Works like a charm and I am sure I can
feed the slides as fast as you can feed them in a Triad carrier :-)
