Capillary action would be great, in fact, that's how the pros who make focus screens do it, but I don't know how to spurn it on.
I'm getting pretty good results now, simply from pouring wax over one piece of glass and then placing the other ontop -- I just need to keep everything super clean. Too often, contaminants get suspended in the wax, and it's a real effort to keep this from happening (i.e. all have failed so far.)
