and that expert drum for 4x5 does 6 sheets at a time buts costs $250! Wow!

The problem with the Expert Drum from Jobo it is very hard to get the chemicals in to the drum. There is a hole for each film and the whole thing looks like a cylinder for a revolver (6 shots). The drum needs to be moving the whole time the liquid is being poured in or it will not fill correctly. Plus the diameter of the thing is huge and it will not make a full rotation on a Unicolor motor base. Maybe people in the engineering trade could modify it so that it will make a full rotation but it is out of my league to try and create something like that.

Myownself, I tray develop. With PMK I use Nitrial gloves and don't worry about it.
