Subject: copper plated tungsten rods

Hey  all,
Knowing that the skin effect causes most of the  current to travel on 
the outside of conductors, would it be worth my  trouble to copper plate the 
tungsten rods in my spark gap?  I have a  few ideas of how to do this, but I 
am not sure if it would be worth my  time.  Thanks.
Scott Bogard.





Hi Scott,
 
IMO, No. The copper plating would burn off rather quickly. The purpose of  
using tungsten is that it does not burn off like copper. Tungsten coated copper  
would do more good than copper coated tungsten, but neither is really worth 
the  trouble. A copper jacketed tungsten rod, with copper starting a ways back 
from  the tip might have useful electrical and thermal properties.
