I did an MF projection for our local stereo club which worked out rather
well. I used GePe 6x6 and 6x4.5 mounts, with an alignment guage fashioned
after the ones Reel-3d sells for 41x101 mounts.

With careful mounting, I found we didn't have to adjust the projectors
at all after the first slide was aligned.

One drawback of the GePe mounts is that they are very close to full
frame, so on the 6x6 (and 6x4.5 when used in landscape mode) you have
--very-- little film adjustment for window setting. So there were
some images I just couldn't mount for projection, even though they
worked well in the Spicer mounts.
