I did about an hour google marathon search session basically asking what the most precise, adjustment laden enlarger is in terms of alignment and came up with an amazing amount of nothingness. What I mean by this is for example, the design of the bellows and stage assembly of the Beseler CB7 has a more precise and adjustable alignment system than the more spartan but still popular 45MX. I have the assembly for a mural enlarger project and it got me thinking about why more enlargers do not have some form of worm driven adjustment on all critical axis like precision X, Y & Z staging does. For example, when in my early 20's I built and aligned hi-tech wafer probing stations that employed an extreme amount of precision and adjustments: http://www.ppli.com/ I find the alignment of enlarger to be used for large prints along these lines and would like to either build in more precision and adjustment or cut to the chase in terms of what is the most capable enlarge in this regard. I don't believe they have to be 8 feet tall and weigh 400 pounds, I worked on this kind of stuff, it was the design, not a massive build that made it work well. So my question is what is the most precise and adjustable 4x5 enlarger out here that would not be a huge amont bigger than my current 45MX?
