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.
The plastic dividers sit in a groove that is routed into the ends.
The "exhaust" goes out the top, but it is siphoned from the bottom.
