Just thinking aloud. I've read a number of threads where lots of people have jury rigged their own processing equipment, and I was wondering whether it would be worthwhile having a standard processor specification now that film processing is more of a small scale operation. What I mean by that is a standards committee made up of knowledgeable engineers could specify certain standards, and as long as those standards where met parts could be cobbled together, regardless of the manufacturer. eg. Jobo tanks could be a standard (Jobo cog size, dimensions). So all equipment for rotating (whether a manual crank or motor) would need to interface with Jobo reels. Tempering bath sizes would be standardised to allow for fitment of the largest Jobo tanks, and specify external dimension so things like lifts would slot in. Lift size would be standardised, and position for attachment of rotating, lift motors, chemical pumps and drains could be standardised. Motors could be standardised to have minimum and maximum torque and rpm, and obey certain electronic commands. This way standard off the shelf components could be used for pumps, motors, controllers as long as they adhered to set standards. Manufacturers may come and go, but since all the specifications are open source, if there is a great demand for a certain part someone could tool up and manufacture and know there is a market out there. Standards would specify how things fit together, but not specifiy the way individual components are built. Has anything like this been thought about before? Would it be useful? Should I stop inhaling chemicals?
