Great design. I need one for 4x5 film.
What is keeping the plexy sheets apart? The water is entering from the top tube ans leaving also from the top at the other end? Would it not be better to have the dirty water leave from the bottom? thereby causing the fresh water to washover and down the film adn
out the base tube.
Looks like it is from the bottom using the siphon principle.
