[TheForge] Yellin question

[Chris Worsley]

Steve,
After reading some of the other replies, I could see that brazing or gas 
welding was an option. It just didn't occur to me at the time. It also 
looks like the round rod was chiseled after looking again at the book again.
Consider making a graver out of something hard like a cement nail and 
engraving on the thin sheet. That might work for you where chiseling 
might not.
