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). Beyond the fact that 95% of all CCH renew efforts are attempted for "cosmetics" alone, a great many pros are not comfortable in having it done to any classic double. I won't name names, but they are not unknown.
In fact, ALL the top name UK makers send their CCH work out to long-trusted workmen. Along with blacking.
And there are good reasons for them to do so.
