        I am seeing that some are having problems with aluminum pop rivets. At
  work we use aluminum pop rivets for NON-STRUCTURAL applications.
  However, when we use pop rivets for structural applications we use
  STAINLESS STEEL pop rivets. Yes. Stainless pop rivets are available and
  are much stronger than aluminum and being stainless no problem with
  bi-metallic concerns.
  
  Check a McMASTER CARR catalog. If you do not have access to a catalog,
  try searching the web for McMaster Carr.
  
  Maybe Force 12 should consider a switch to stainless in leiu of aluminum
  pop rivets.  73 de  Arne N7KA  New Mexico
  
    Arne: This is a great suggestion and thank heaven for TT.  That's a good 
 idea if they and the hole are coated first with silicone or the other 
greases and 2 
 rows of rivets are used at 90 degrees.  It still only gives a little over 90 
 degrees of a "Press Fit" for RF conduction instead of 360 degrees.  I'd use 
6 
 of these rivets real close to coated joint and 3 further back to achor the 
 tubing mechanically and electrically.  Even I could live with that.  Do they 
make tinny tiney small diameter copper pop rivets for copper wire Press Fit 
Splices?  This way the weak fingered don't have to twist the wire joint 
before soldering it.  k7gco
