Cool Roger, they say smell is one of the most powerful triggers of memories. My son went through the local community colleges welding curriculum so he can probably relate to your memories more than I. I guess now that I think about it, welding smells do remind me of when he still lived at home and our nest didn't seem so empty. I still have some of the pieces he used as tests to get his certs. He was so proud of his work and so was I. Sorry if I seemed flippant with my response to your post.
