22 cal barrel liner
A recent post regarding a thin barrel 38 cal has caused me to reflect on several completed projects that were accomplished by an acquaintance near my use-to-be-home in eastern Kentucky.
I was never into "re-lining" barrels for 22 cal rim-fire but subconsciously I've always wanted to know more about methods used. Though the lathe he used was quite small, the culmination of his projects were quite remarkable. This said, he wouldn't reveal his techniques. He did state that the used barrel was drilled over-sized and the barrel liner was soldered to place.
When the project was completed, he hot-blued the barrel. It was practically impossible to see a line between the original barrel and the barrel liner at the crown. Additionally, there was NEVER a solder line visible.
1. How is a barrel drilled the entire length? The lathe was too small to chuck a long drill in the tail stock.
2. How is solder applied? Is solder only applied at the ends of the barrel once the liner is in position?
3. What kind of solder is used to withstand hot blue?
4. When the barrel was crowned, and before bluing, the liner could not be detected at the crown. The appearance was that of being a single piece of metal. After the barrel was blued, there was no solder line. How can that be accomplished where no line is detectable?
For those having fought for it, Freedom has a flavor the protected will never know.
