Thanks, You might try doing it in a medium size cardboard box, side cut out and draped with several layers of blankets. Your arms through the sleeves of an upside down overcoat draped over the box too. All this in a darkened room. It will be easier to switch tools scissors etc…
I modified the jig for 828 only to discover the mechanism in my Bantam that uses the sprocket holes is malfunctioning. But the film is easy to use with it without holes.
The issue I've recently discovered is the black crepe tape I'm using is not completely light tight. So I have to find another way to reseal the cassettes. A cassette i did a couple weeks ago that was sitting out in my workroom had bad light leaks through the tape.
