Homebrew PCBs

I fabricate RF boards and consequently employ a lot of rivets for 
grounds.  I use solder coated rivets from International Eyelets. 
Used to carefully crimp them using the proper tools.  But have found 
use of  a small ball-peen hammer in conjunction with a flat steel 
backing plate  is just as effective and a lot faster.  The resulting 
crimp is  not as  uniform nor as pretty but it is then covered with 
solder anyway.
