Simmaroller / Expert combo for neg developing?

[andrew pell]

Hello all,

 

A year or so ago I was given a Simmaroller motor driven base that has

a wash/wave action and I am about to order an Expert 3006 drum for

4x5 neg developing.

 

From a quick scan round the last few days posts, does anybody know

whether this is a viable combination or should I look out for another

setup?

 

The distance between the rollers is approx 5.5" - how long is

the "contact patch" on the body of a 3006 tank? It drives at 30rpm

(single direction rather than reversing) and the wash/wave motion

sloshes the soup along the axis of the tank as it rotates - is this

likely to not be ideal for the internal makeup of an expert drum?

 

Any help gratefully received.

 

Thanks

I've since found the Jobo USA site recommends reverse agitation for drums - I can see the logic of this for developing film in "print" tanks re streaking as the soup sloshes one way only over the ridges but does this also apply to using an Expert drum?

PS anybody know where I can get hold of a uniroller base in the UK? Hen's teeth are positively abundant compared to these things ;-)
