Yes it does look like a job that's in 'the too hard' basket.
How about if 2 guys, one on each end, coordinate a steady & straight movement of the blade freehand like you say but keep a focused attention on the water level adhering to the blade, as the grinder turns, like on the demo tapes for ordinary chisels & straight-edged knives? Maybe a 3rd guy looking at it straight on, is needed for that?
The guillotine blade is a perfect rectangular piece of metal. It's not a samurai sword but it is longer than the average machete.
