510-Pyro & Jobo

[Alan9940]

Has anyone used 510-Pyro and the Jobo Expert Drums for rotary processing? Results?

In the past, I've successfully used Pyrocat-HD and PMK if, with the latter, I dump & fill with the developer halfway through the time. I'm just wondering about oxidation with 510...

Thanks!

For clarification if I may. Do you mean that you use two lots of developer but change it half way through? If I have this correct, why do you do this? Does PMK oxidise that quickly with rotary processing?.

I appreciate these questions get you no nearer an answer but I am curious about why PMK oxidises that quickly

Thanks

Yes, I have two 1L bottles of fresh PMK that I change halfway through the development time. And, yes, I do this because of oxidation. Though I've never directly tested whether oxidation is an issue, a fellow photographer whom I have great respect for does exactly this when using PMK on his Jobo. Could be he's just following along based on what he heard...dunno. But, bottom line is: can't hurt.
