Cardboard mounts

[P3D Ivester, Paul <ivestep@xxxxxxxxxxx>]

I have been using cardboard heat seal mounts for most of my stereo
slides for several years, and have had no problems in projection in
either the Nord or the TDC 716 projectors.  The key is that whatever
type of mount you use, the mounting must be accurate.  I use a
fixture that I built which holds the film chips in position on the
mount, which is above the Reel 3D mounting gauge.  The fixture
allows moving the slide from side to side over the mounting gauge
in order to line up the near and far points.  Magnifier lenses above
the slide allow viewing the slide in stereo while adjusting the
window.  I then tack the film chips in place and then heat seal
the mount.  It takes me the better part of an evening to mount a
roll, but the results have been quite satisfactory, and my mounting
costs are low.   I use the aluminum masks (EMDE and Albion) only for
7 perf, and would probably use heat seal for 7 perf if the mounts
were available.  I will admit that the sharp edges of the aluminum
masks do look nicer, but my audiences are used to heat seal mounts
on 2-D slides, and don't notice a bit.
