I don't have any machines with enough travel to be able to adapt/improvise a
grinder setup for sharpening about 32" of blade edges.

I think you could sharpen them with a hand-held grinder as long as you
don't remove any metal from the vertical surfaces or change the angles
much. Irregularities that are perpendicular to the cut won't affect
its straightness.
