Thanks! Dunno about sub-second shutter speeds -- maybe it's my advancing age and decrepitude, but I think even a second would be hard to do repeatably. The pivot screw tensions the shutter lever against a paper friction washer, the shutter stays wherever it's put. The other roundhead screws limit the travel. I originally bought ISO 400 film, but after seeing the times down around the 1 second mark, I ordered some Delta 100 to get out in the five to ten seconds (or more on the inevitably cloudy WPPD) range.
