Maybe they aren't even necessary. If you regularly (like, every year)
grease the bearings, nothing bad will probably happen. I lost my
pedal dustcap in 1987. Nothing bad happened for 8 long years, despite
the exposed bearings.

It's not the retaining the grease that's the problem as much as keeping
out the grime. Under the freewheel, it gets mighty grimey. I've
already replaced bearings and cones on that wheel once, so letting grime
in there would wear those components out prematurely.

The approaches suggested by Chalo and Werehatrack look like nice,
simple easily implemented solutions for keeping out the grime.
