A tight door

I really want a tight seal on the entry to our earth oven.  Goatheader and I talked at length this morning about the need for a "hassle free" door--something that seals well and opens and closes easily.  It would be a real bonus if it looked good, too and didn't have any moving parts.

One of the links we've been studying shows a real spiffy earth oven with a real nice tight door.  I copied three photos from that online resource to display here.  (I sure hope that meets the "fair use" aspect of US Copyright laws!)  Anyway, you can read all about this oven yourself by clicking here.
