Expert Drum on a Unicolor base - good idea or not?

[andrew_herrick1]

Hi all,

 

Firstly thanks a lot to all the people who have helped me out in the

past. This is a great forum and I appreciate people's time and

insights.

 

I am wanting to trade up to the Jobo Expert drum system but don't

want to shell out for a Jobo CPP-2 with lift. I wondered if it is

practical to use a Jobo expert drum on a Unicolor base?

 

If anyone has experience with this and can provide some advice

(especially with the Expert Drum 3010, the one that takes ten sheets

of 4x5) I would be most grateful.

A fully loaded 3010 is very heavy, probably too heavy for the Unicolor base.

I have used a 3010 expert drum with 10 sheets of film and 850-900 ml of chemistry on the unicolor base for several years sucessfully. The drum tends to walk down the base even when the base is leveled. To prohibit that I put rubber bands and tape around the base so that the roller base wheels were trapped between the tape. The height of the tape plus rubber bands stopped the drum from walking.

 

My negatives are fine. I have used the same drum in a CPA-2, read negatives from each system on a densitometer and found the results to be identical.

 

One point: I process only b/w film. I have not tried this with color. My guess about color: If you can control the temperature of the chemsitry there should be no problem.

Hope this helps,

Bob

?? You got an Expert drum to fit a CPA-2 ? Please explain.

Sorry - Quick retraction. I was thinking of CPE-2. -- How dumb!
