I have a film rack for tanks that I had to fashion a handle too, b/c the orginal one fell of. It was actually easy, as I bought a screen door handle and used two small bolts and nuts through the cage. Viola...or so I thought. I ran two batches of film this evening and noticed on the first batch the reels were really dirty. I thought it was strange, but didn't panic, so I wiped them down. Then on the second run of film, I noticed the reels were worse and that there was gold color flakes running all over the film. Lame. I got most of it off, though it was really everywhere. It quickly occurred to me the bolts were black and corroding, and it appears the handle is too. So, a few questions. First out of curiosity: What is it, and what is eating it? Then the more practical questions: is there hardware that will work for this? If it was flaking in the developer, any guesses if these metal flakes pose any adverse effects to my tank of developer (replenished). And/or any effects to the film I've processed (opposed to the obvious fact that there are flakes of metal on it.) Unless I'm missing something else getting eaten...I'm surprised at how much of this grit there appears to be so quickly. Advice and wisdom greatly appreciated!
