It's also important to have the right racquet. If you have a head heavy racquet, which I believe baseliners prefer, you won't be able to manoeuver it at the net. I switched recently to the Head LM Radical, in part because it feels so good at net.
Benjamin, forgive me, I couldn't resist. I really admire the way you hold your own and take the jibbing on the racquets board. I think your students are lucky to have you.
I would strongly recommend a few hours with a pro before trying to learn the volley on your own. The foot work is also completely different from groundstrokes, and getting it right from the beginning will save you a lot of aggravation trying to match the right swing with the wrong footwork.
