Re: [Leica] Roller processing

[Ken Wilcox <wilcox@umcc.umich.edu>]

I use a Unicolor film drum and motor base. I bought them used for less than
$50. A good starting adjustment factor for developing is -15% of the time
used with regular tanks.

A stainless drum will not work on my motor base because the diameter of the
drum is too small to engage the rollers.

Cheers!
