[AT] Rivet how-to

[John Hall]

I did some research today and I'll second the motion that the head is 
conical and the rivet is braded to look like a button. I got my info out of 
my machinist handbook. They list conical head rivets although they don't go 
to a sharp point.

Looks like I'll be making rivets now!!!
