No tape heat-seal mounting

[P3D Richard M. Koolish <koolish@xxxxxxx>]

I don't use any tape in my heat seal mounting process.  Here's what I do:

    1.  I use a lighted film cutter to get nice square cuts.  It also helps
        when the frame edges are dark and hard to see.  I've also been using
        a head mounted magnifier to see the process better, although I
        suppose reading glasses would also work.

    2.  I smooth down the outside set of positioning tabs in the mount because
        it seems like the film chip won't completely flatten out if I leave
        them up.

    3.  Using a fairly large pair of round point tweezers, I position the film
        chip against the inside stops.  The right and left chips usually are
        positioned against different vertical stops because both cameras I
        use seem to have a bit of vertical mis-alignment.

    4.  Holding the film chip in place with the tweezers, I close the mount
        over the film chip, holding it in place with the mount and withdrawing
        the tweezers as I do this.

    5.  I then use a small binder clip to hold the mount closed.

    6.  Do the other side.

    7.  I check the alignment under an old army map stereoscope and if anything
        needs fixing, I go through the process again.

    8.  If everything is in alignment, I seal the mount using a Seary 2x2 heat
        sealer that seals the three sides of the mount except the hinged side.
        It doesn't seem to hurt that the hinged side isn't heated.  I usually
        tack seal the end of the mount before carefully sliding the mount
        fully into the mounter to do the complete seal.

    9.  As a last step, I use a Red-Button viewer to double check the slide.

If the mount is always held closed by your fingers, a binder clip, or one
tacked edge, the slide shouldn't slip during this process.
