This is 4x5 single sheet daylight developing tank. it requires 150ml of developer. You can easily load sheet in the dark bag and develop it at the daylight. For fixing and washing i recommend to use a small tray, its amazing to watch the fixing process on the light ! :D And you can be sure by observing it that it's fixed properly.

Extra waterproofing

For a longer lifespan of the tank i recommend to vapour-proof the whole tank and lid in Acetone vapours. During that also pour bit of the acetone into the tank to extra-seal the bottom. For the inlet part of the lid i used small brush and acetone to smoothen the first layer after the supports.
