Francesco,

When I first started working with 11x14 and 8x20, I used a unicolor drum on a Bessler motor base. Now I use a Jobo and a print drum to process my negatives.

I have a Nu Arc plate maker with a vacuum frame still from when I was printing in Platinum but It has been in the basement for almost 5 years. I just use a piece of glass over my nagatives while contact printing. I have owned and used contact printing frames but find they are more trouble then they are worth unless you are using a POP paper which would need to be inspected to check exposure.

I have to warn you that ULF negatives are very addictive. They are a joy to work with, and seeing the negatives hanging to dry after processing makes any inconvenience the cameras may cause during shooting worth the effort.
