Do I recall when such a room as you describe was known as a "Faraday
Cage?" Or am I having one of RvP's "Senior Moments?" (No offense, Ron!<span

<div>The ideal material I have seen is used in RF shielded room
walls. It is 3/4" high-density particle board, skinned with galvanized
steel on both sides, maybe 28ga. Very flat, and very smooth. It will
bow just a little, maybe 1/2 inch at the most, when you pick it up from
the end. Came in 4' x 12' as I recall. Don't have any idea where you
could purchase it at a reasonable cost. I was hoping they would have a
sheet of it leftover when they built one of the chambers where I used
to work, but they didn't.</div>

However, a common element to this discussion is that you need to
measure how flat the surface winds up. What tricks are you guys using
to actually measure how flat the surface is of the bench you just built?</font></p>
