Mail*Link(r) SMTP FWD>Fab-Re: More nailheading Phil, I'm glad somebody else remembered Bob's process for direct metalization of holes during the drilling process. I was thinking of Bob as I was writing my (published) humor for the day. As I recall though, the low temperature fusible metal was placed on the bottom stack so it could be "pulled-up" the drill flutes and roll over the helical edge of the drill and be "smeared" on the hole wall -- just like we don't want resins to do.

Worth has a patent on a nail heading process wherein he imposed on the top of the drill stack during drilling a layer of another foil and nailheaded (smeared) it all the way through the the hole thus eliminating electroless processing.
