Help with stovetop espresso

[stovetop1]

Can someone help me get this right. I cannot seem to make an espresso on my stove top. Here is exactly what I do.

1. place water in the bottom container.
2. place coffee in the filter/funnel, and set it in the holder.
3. Screw the top and bottome tigether, fairly tight.
4. Place it onto my stove at Med/Hi heat.

Is there something I am missing, I never seem to get any coffee this way. After 20 minutes there will not be a drop.

From what you described, you're doing everything right, but there's something you're not mentioning and it could be a number of things. It's possible there's something wrong the grind (try grinding it a little coarser), or maybe you're not using enough water. The latter seems a little more likely, since I still do that from time to time first thing in the morning. You might want to try just turning up the heat on your stove a little bit.
