JOBO

Last week I started my very own JOBO Hospital. Waterford had 4 working JOBO's at one time (a JOBO is a machine made to develop various sizes of film and prints). Over the years they have gone bad and put into storage. Last year the last one gave up the ghost. During the summer another one was found and purchased off of eBay. When I was hired one of the things I wanted to do was repair the ones that were dead and get them all running.

This term the Juniors are going to be doing color E-6 medium format, so even though we have one working unit, I had some time and decided that I would dive into them. I completely disassembled all four of them, determined what wasn't working, cannibalized bits'n'pieces and got two of them running perfectly. I even calibrated the water heaters.

Of the remaining two, at least one of them can be brought back to working condition. I need to have the motor looked at and possibly rebuilt. The fourth one would work except that the heater control switch has been ripped out of the circuit board. I'm afraid that's beyond my level of understanding. If anyone has a broken JOBO CPP/CPA-2, let me know. I could use the parts.

Here's the film developing room. On the left is my NuArc exposure unit.



Tomorrow I'm rebuilding the large Seal dry-mount press...during Christmas Break I might add. Aren't I dedicated? Actually I'm just avoiding potential problems and it's really a selfish motive.
