Thanks Cecil, for the link to the carbons at Walmart. There might be 
hope of getting them yet.
Only place that had them last year was in a big box quantity that cost a 
fortune and would have lasted me a
lifetime.
Keith, Gene has explained it well. Last thing I used my carbon arc torch 
on was attempting to pull a
rear brake drum on my 39 Ford. No luck yet . I use the bigger carbons, 
not sure but think they are the
half inch ones. They are the biggest that will fit in the torch holder.
I don't have any photos handy but google turned up some pictures that 
are similar to mine.
