P3D Re: Cardboard mount issues

[Paul Ivester <pi@xxxxxxxxxxxx>]

I use cardboard stereo mounts routinely.  I prefer them 
mainly for reason of cost.  The large variety of openings 
available with the Spicer mounts is also an advantage.  
I have built a mounting jig that allows me to mount in 
cardboard with great precision.  I shoot mostly 7 perf  
now, but sometimes still shoot 5 perf.

For 5 perf slides, use the heat seal mounts.  I greatly 
prefer the convenience of heat sealing as opposed to 
taping or gluing.  The alignment tabs can be convenient, 
but they get in the way when adjustment is necessary.  
They would be better if there were multiple tabs in the 
horizontal direction rather than vertical.  I find the 
edges are tolerable, but the Spicers look better, though 
still not as good as  Albion or RBT.

For 7 perf slides I use the Spicer mounts.  They are 
accurate and have clean edges.  I like the variety of 
openings.  I usually glue them shut because it looks 
neater and makes them stiffer.  I would much prefer heat 
seal adhesive.  A dark adhesive would help opacity.  
Alignment tabs might be convenient, but they would need 
to allow for easy adjustment.
