I've thought about this and it won't cause a problem, the area will
simply get a coating of powder at the same height as the roller, it
can't build up because it gets ploughed as well.

If I knew all of this was going to work I would build the machine
proper but I don't, this will work or at least work well enough to
check. Cutting the end off pumps, hole sawing some receptacles in the
mdf base and adding a single threaded rod and nut in the already
hollow handles is all that is required. That's 5min. All this
cutting and gluing perspex is a big job in my workshop.
