Thanks for the great photo setup of how you produced the barrels for those great "9 mm Luger" Target Pistol that you so proudly display on your Web Page at http://www.vapensmedjan.com

Those are certainly very beautiful, High Quality Custom Firearms that you make .


However that picture demonstrates the most accepted method of custom fitting high quality firearm barrels . In small lot quanities .


But is a most time consuming method and not suited to the mass production of numerous firearms to the level of interchangability that was previously noted by "Hugh" , in having several barrels lock up at the same point of index .


Consider the problem of how to produce this mating of barrel and fork in quanities of say "One to Two Thousand Units" .


This presents a problem that demands a high level of fixturing and precise control of the accuracy of the final product . That is where the method that I have described provides a quite practical and workable solution .


As I said before , Just my idea of one of the possible ways to accomplish the task .


(Incidentally Where is the lathe dog that is needed to drive the Barrel ?)
