Stereographoscope - Roswell Style
I originally was going to make a Holmes style handhold viewer,
but the project kind of got out of hand. The large piece of glass
on the top is supposed to "enhance" the enjoyment of post cards, which
were all the rage at the turn of the century. It is actually a 4"
dia. magnifier with the handle cut off. (can't really say that I
enjoy postcards any more with it) The stereo lenses are f=150mm,
39mm dia., spaced 65mm apart.

Mounting Jig/Goggles for stereo slides
To help speed the mounting of film chips in the stereo slides,
I built this jig/goggle. The goggles allow you to see how the
slide looks, as you are adjusting the film chips in the mount.
