I've been lazily building a 16mm lab for ECN-2 color neg / ECP-2 color print / E6 color reversal and BW film from 2007. I've redesigned it a few times (for previous revision, see http://www.youtube.com/watch?v=wB4a_RN6U9Y ) but this time I believe I'm going in the right direction. I just completed the first tank rack with slots for seven ~9 liter tanks max 70 cm deep. Look at this:

This first rack is the "dark side" rack, then there will be a 11-tank rack (similar in design) to total to 18 tanks, and a dryer.

Tanks are made of 5mm acrylic (plexiglass) and are easily inserted in rack from below (this way they can ejected for easy maintenance):

I have also control panel electronics mostly done.

I'll update this discussion whenever I have some real progress to report!

What a fantastic project! You just need a little motivation and get it all together.

Hi everyone,

I have finished the lab! Some minor fixes to do, but basically, the film moves neatly through the lab, remjet removal and drier works, etc.

Here's some video footage of the laboratory developing its very first films: http://www.youtube.com/watch?v=SfV_p-mijwM

This is brilliant. It is exactly what I am in the process of building as there are no B&W reversal processors in the southern hemisphere, and now only one ECN-2 lab in the southern hemisphere that will accept lengths of colour neg film of less than 10,000ft. I process 1800-2000ft of B&W reversal in a lomo tank and it is a real chore. I have to send you my details to get your thoughts on my ideas.
