The recent thread about a hypothetical ballasting car that would actually be able to work on a model railroad layout got me to thinking. (Dangerous, I know.) Came up with an idea for such a piece of MOW equipment, but then decided that it would really work better as a hand-held tool (certainly not as operationally cool, but more effective).

DISCLAIMER: I haven't actually made one of these, so I have no frickin' idea if it would actually work.
I envision this being made out of cardboard and glued together; the inserts would seal off the slots that fit over the rail. (Of course, it would be nicer in soldered sheet brass; that, however, is a bit beyond my meager capabilities.) The size and shape of the openings would have to be determined experimentally; one wants the ballast to flow freely, but not *too* freely. And the side chutes could be angled down away from the track for a prototypical profile.
So what do y'all think? Might work?
