Thanks. That's exactly what I'm looking for (if I can figure out how to 
apply the math, now).

Well, it's sort of nebulous ideas at this point, but basically it boils 
down to using one or more slats of wood (think 1/4" plywood) or similar 
material as support for a load that's constrained to move vertically. 
The plywood "beam" (or column, I guess it is technically) is rigidly 
attached at both ends. For a given load and allowable amount of 
deflection I want to find out how thick a piece of plywood I need, or if 
I need to use something more rigid like aluminum.

Thanks again and clear skies.
