I use a Paterson Orbital for processing 5x7 and 8x10 film and if I only need to process one or two sheets of 4x5. I have two processors, one with the fins still in place and one where I’ve removed them and all I can say is film processed in either are identical, very evenly developed. However some...

Of great use Trevor. I received an orbital in the post this week and was surprised to find that it was new/unused, so I want to get this right first time. I tried local art shops but as yet have found nothing although there's plenty of time to get it right.
I'll take a look at those door stops Dave but I was imagining something harder, probably because I had it in my mind that they were glass at first sight. |

The smaller the better, Gavin, as they're hemispherical. Hardware shops should have them. Just ask for wee plastic domes that protect doors from hitting cupboards . And they're self-adhesive.
I have become a disciple of Trevor's since starting to use an Orbital for 7x5 processing. |

I don't think that their shape should matter as they are there simply as spacers to prevent suction making removal of the medium difficult. Because they are on the non-emulsion side they have no effect on the developing process but do allow washing water to circulate under sheet film.

I use a Patterson Orbital - I found I have to remove the fins as some negatives suffered from bromide drag in sky areas (Foma and Rollie IR). I used little drops of fish tank silicon sealant to keep the film from the base. I also use the motorised base as I feel this give a more uniform (although continuous) agitation. At the moment I am using 200ml of solution(s) although I did start by using 100ml. Any one using more or less? Mostly I develop 4 sheets of 5 x 4 film, only occasionally 10 x 8.

I haven't removed the fins on mine but I think I will. And I scored the base with a Stanley blade on mine to prevent the film from sticking.
