Wow, at $51 per for that little sprocket I can see why you're wanting to
make your own.

Guess they're not producing them now at the same volume as they were in
say the 60s, huh?

I don't think they were cheap then either. I ran
the projectors at the local movie house while I
was in high school (about 68 or 69). The one
cardinal rule was "don't drop the sprockets or
the Cinemascope lenses"
