While the CCH process is interesting from a intellectual standpoint, its proper execution is not something for the garage gunsmith to toy with (even though such hobbyist diversions are now popular). ... a great many pros are not comfortable in having it done to any classic double. .... And there are good reasons for them to do so.
KR,
I gotta disagree on this one. I think as many hobbyists as desire should toy with such a process. Gunsmiths are typically not specialists in most of the areas they work. In fact, most are specialists in only one of the many skills needed to be a gunsmith. A hobbyist has a huge advantage in the time dedication he can put into learning a process that a pro just can't afford, since he is busy trying to make a living. Oscar Gaddy was such a "hobbyist". Some other names you'd recognize from here were once hobbyists and now pro's, some of them top shelf.
Should a beginner start with an irreplaceable gun? No. There are plenty of chunks of steel around as well as dead doubles.
