Thanks for the added information fellas.
So what's the sugar developer formula?
Kerik...ouch on the AgNO3!
Joe, I like your design of the helper tray. It seems to utilized the tilt tray method without using too much developer.
In Coffer's manual, he has helper trays for small plates that just have low sides and a hole. For larger plates he has three higher walls and one wall low. The low wall allows him to put his beaker close to the plate and flow it on. He also mentions that he puts a piece a thin glass or plexi to keep the plate off the bottom instead of hole.
Do you lose much developer on the larger helper with a hole?
