 Dwight, I double checked the metal and we're both mis-remembering.
 It's not aluminum or stainless but just tool steel that Russ polished.
 You can stick a magnet to it.   Therefore, probably keep these out of
 the humidity or they will rust. 
Very timely.  I had an occasion to drag out my 10-hole punch yesterday and
modify a couple of diskettes for my N*.  The first time around I had a lot
of tearing that resulted in the dreaded "hanging chads".  When I took a
close look at the die plate I noticed an irregular raised burr around all
the holes.  After taking some fine-grit sandpaper to the surface and
leveling the holes it started working a lot better.
Maybe this will be helpful to other users.
