To all interested members who have wondered if this project has died, it has not. It is temporarily on hold until such time as finances and interest resume.
A member of the other forum approached me about a project that ended in a major disaster some years ago. He wanted a 9mm Walther P1 barrel liner removed and a 30 Luger stepped liner installed. I did a test barrel and it worked out very well. I then did two more and managed to burn out a set of HSS drill bits and a reamer. I upgraded to Cobalt and the next one turned out quite acceptable. I've done several more. Still waiting for a review.
