[Leica] Re: Eight reel tanks

Hi Arche,  When I worked for Unicolor as a sales rep. we didn't worry  
about fill time on the 6 reel film Unidrum. You could get a seventh  
reel in if you let the adjustable piston hang out the bottom a  
little. Just start timing from the time you finished filling.   
Obviously Unicolor recommended running some test rolls before  
committing high value images to the process.  Unicolor's first  
consideration was processing color film so they calibrated their  
times for their chemistry. But I don't think there was any difference  
if you ran Kodak color chemistry.  They felt B&W was not a critical  
with more latitude to play with and no exposure vs density curves to  
cross. Development time was reduced due to continuous agitation on  
the roller of course. What drum are you thinking of using?  Richard
